All rights reserved. 20. Steam engines have two ports, allowing excess steam to flow through. Looking for efficient setups? They produce electricity by consuming steam, using water pumped from an offshore pump that was heated to 165C steam with boilers or to 500C steam with heat exchangers. and another post in that thread (which calculates the solar panel to megawatt ratio in a different way). All trademarks are property of their respective owners in the US and other countries. The optimal ratio of accumulators per solar panel relies on many values in the game. Geplaatst op 3 juli 2022 door . The true value comes from the following facts: It takes 1 kilojoule of thermal energy to raise 5 units of water/steam 1 C, You've heated water from 15 C to 500 C; 500 - 15 = 485, Consuming steam in turbines gives you the same amount of energy back as electricity, Steam is consumed by steam turbines at a rate of 60 units/second. All trademarks are property of their respective owners in the US and other countries. A reactor produces 40MW, plus another 40MW for each active neighbouring reactor. Steam that has a higher temperature than the maximum temperature of the steam engine (165C) is consumed at the normal rate (30 units/s), and does not yield more electricity. Calculator for the Nuclear Reactor. All trademarks are property of their respective owners in the US and other countries. Now you have 0 waste of fuel. Not sure where you got those numbers from, but in 0.15, small pumps and offshore pumps pump at exactly the same rate: 1200 fluid/s. Electricity has to be produced before it can be transferred to consumers over the electric system. Valve Corporation. This is taken from Accumulator / Solar Panel Ratio (which calculates this in an impressive mathematical way!) If you inexplicably want to go back to a 4 year old build of Factorio then you will need to build 14 boilers in a row (they each used to heat the water up by a little bit), followed by 10 steam engines. These fuel cells are then burned in a nuclear reactor to create heat. Thanks. This page was last edited on 16 February 2022, at 11:27. by Honktown Fri Jan 03, 2020 8:34 pm, Post Yes, there is also a maximum throughput for water that depends on the distance the . Designed for supporting scaled up machines from "Schall Machine Scaling" mod. Heat exchangers will not produce steam until they reach 500C. Here are the total requirements for certain amounts of reactors, with everything rounded up to guarantee maximum energy production. A "close enough" ratio is 20:24:1 accumulators to solar panels to megawatts required (for example, a factory requiring 10 MW can be approximately entirely powered, day and night, by 200 accumulators and 240 solar panels - this approximation differs from optimal only in that it calls for 20 extra solar panels, which is negligible but remember that the difference between the "close enough" ratio and the optimal ratio increases as you add more solar panels). Each offshore pump outputs 1200 units of water per second. Additional comment actions. Factorio - The Best Nuclear Power Ratio To generate ten fuel cells, you will need one U-235 cell and nineteen U-238 cells. This equation could also be used to remember the vanilla optimal ratio given its simplicity. The heat exchanger exchanges heat between a heat connection and water to produce steam. Heat exchangers have a heat capacity of 1 MJ/C. 9.89 gigawatts is a lot. The glow of the heat pipes indicates temperature, with left ends being at the upper limit of 1000C. Use the lake west of your copper mine. It takes 200J to heat 1 unit of water by 1C. Heat exchangers are pipes too. factorio offshore pump heat exchanger ratio Try this checklist before you completely revamp your power source. Don't ask me how that works.) In a vanilla game that's. what, 1k science a minute? Using steam engines for power does not produce pollution, however using boilers to heat up the water does. Look at the windows in the pipes, hover over the pipes! Heat pipes (also in reactors and heat exchangers) glow with high temperatures. Tileable Nuclear Reactor Design. #footer_privacy_policy | #footer . The above ratio can be calculated from information available in-game: One boiler consumes 1.8MW of fuel and produces energy stored in steam at 100% efficiency. EDIT NOTE: The original version of the post used the wrong output for steam turbines (5.8 MW instead of 5.82). using 3 pumps and a tank, you can feed 28 heat exchangers. Doubled the heat capacity of water from 0.1kJ per degree per liter to 0.2kJ. This ratio is. In general, nuclear power is produced by the following production chain: Uranium ore is mined and processed to uranium-235 and uranium-238, then uranium fuel cells are created from the two. Nuclear reactors have a maximum temperature of 1000 C. Unlike boilers, nuclear reactors will not slow or stop their fuel consumption if their output isn't being used; they'll constantly use up fuel cells at the normal rate of 1 fuel cell / 200 seconds. Is steam able to reach all steam engines? (100% neighbor bonus per adjacent reactor). u/asdjfsjhfkdjs calculated the convergents of 500:291, and found that 7 : 4 and 55 : 32 are both fairly accurate approximations. So we know that one offshore pump can supply 20 boilers but is that the same for heat exchangers? But the water only gets heated up from 15C to 500C, so by 485C. HolyGarbage . See also the applied power math tutorial to answer the question how much coal do I need? This can be extended as far as you want; every additional 2 reactors will provide an additional 320 megawatts of heat output. A heat exchanger produces 10 MJ a second, therefore it produces 10MJ / 0.097MJ = 103.0927835 steam per second. Give exchanger max heat you can then let the exchanger turn 25k water into steam. On a lake, very carefully - they consume a monstrous amount of water, and having the multiple required offshore pumps integrated directly into the design is often worth the hassle of wrangling landfill. I have been reading all about Nuclear power so I can convert my factory. (Except that you can potentially turn 8 gigajoules of uranium fuel cell into 40 gigajoules of heat. by Amarula Fri Nov 29, 2019 3:09 pm, Post Press question mark to learn the rest of the keyboard shortcuts. Yogi Berra. can you post a screenshot/blueprint? fox hill country club membership cost. Valve Corporation. Perfectly optimal solar network (Factorio forums), 1 solar panel produces 42KW after factoring in the night (Factorio forums), https://wiki.factorio.com/index.php?title=Power_production&oldid=182968. Fresh water is at 15C while the steam produced by heat exchangers and consumed by steam turbines is at 500C, a difference of 485C, so you need 1 unit of water for each 97kJ, which is roughly 10.3 units per MJ. However you did warn me: Save often and reload if necessary during landfilling. All rights reserved. Each steam turbine take a maximum input of 60 units of 500 C steam per second and outputs 5.82 megawatts of electricity; the 5.8 megawatts listed on the tooltip is rounded. One boiler consumes 1. The main thing to remember is that Factorio generally follows the laws of thermodynamics; if your nuclear reactor produces 40 megawatts of heat, you can get a maximum of 40 megawatts of electricity out the other side. However I want to do a different configuration and want to plan out how many of each type of component I need. fox hill country club membership cost. It must be placed on a shoreline of a body of water on the map, and connected to a pipe or other object that accepts liquids. Each turbine consume 60 water/s so 1200/60=20 turbines. That's actually just odd. makes troubleshooting easier. One exchanger 3 storage tanks plus inf heat. The steam production rate can also be calculated using the energy consumption: 1 Heat exchanger consumes 10MW, so it's putting 10,000,000 joule of energy into heating water/steam per second. Geplaatst op 3 juli 2022 door . The throughput of a fluid pipe depends on the length of said pipe, but you can put in pumps to pressurize the pipe and increase the throughput. Since steam is produced from water in a 1:1 ratio, this also means that 103 units of water are consumed per second. The steam produced is exactly 500C hot, even if the exchanger is hotter. by disentius Fri Nov 29, 2019 9:15 pm, Post So you have 10 + 12 = 22 pipes. Steam engines will automatically adjust their power production and steam usage based on the current demands of the electricity network. It does not require electricity or fuel to operate. Each heat exchanger converts 103 water to 103 steam, feeding 1.72 turbines. They produce electricity by consuming steam, using water pumped from an offshore pump that was heated to 165C steam with boilers or to 500C steam with heat exchangers. Post A steam turbine consumes 60 units of steam per second, which is 5.82 MW. 75 crafting speed, while the induction furnaces use 3 * 1, so the ratio could be fine tuned a bit. Espaol - Latinoamrica (Spanish - Latin America), https://wiki.factorio.com/Tutorial:Nuclear_power#Neighbor_bonus. Your other big concern is fluid flow, and the main constraint is the heat flow along heat pipes. 1 offshore pump: 20 Steam Turbines. A heat exchanger consumes 10 MW. One steam engine consumes 900kW of energy stored in steam, so each boiler can supply 2 steam engines: 1.8MW 0.9MW = 2. Doubled the heat capacity of water from 0.1kJ per degree per liter to 0.2kJ. Includes pipe, pipe to ground, pump, offshore pump, heat pipe. By rejecting non-essential cookies, Reddit may still use certain cookies to ensure the proper functionality of our platform. Heat exchangers produce ~103 steam with a temperature of 500C every second. The offshore pump produces water from a lake or ocean. Id probably put it on or next to either of the lakes in the middle north or middle south. Community-run subreddit for the game Factorio made by Wube Software. 4 Heat Exchangers boil 412.36 Water to Steam per second (103.09 per Heat Exchanger ). And probably how many Offshore Pumps you need for them?

The above ratio can be calculated from information available in-game: One boiler consumes 1.8MW of fuel and produces energy stored in steam at 100% efficiency. One steam engine consumes 900kW of energy stored in steam, so each boiler can supply 2 steam engines: 1.8MW 0.9MW = 2. P UMPING U NITS M EETING P HYSICS S TANDARDS This mod started off as a project to sustain my most eco-unfriendly excessive water needs by implementing some Higher Tier Offshore Pumps. Remember that water in pipes still obeys Factorio physics; if you pipe your water a long distance, you may not get the full 1200/s. Steam that has a higher temperature than the maximum temperature of the steam engine (165C) is consumed at the normal rate (30 units/s), and does not yield more electricity. Don't ask me how that works.). Until then it is advisable to not use more than one pump per water network. (Low quality because reddit wouldn't let me upload the full png) redditads Promoted. (Except that you can potentially turn 8 gigajoules of uranium fuel cell into 40 gigajoules of heat. This page was last edited on 27 October 2020, at 13:19. This produces the 1:20:40 ratio. Press J to jump to the feed. The current optimal ratio is 1 offshore pump to 20 boilers to 40 steam engines. Do the numbers in the "beacons" column represent the number of modules or the number of beacons? 15 - Factorio Factorio Forums View topic - 0. Introduction Troubled by pipes having low flow rates? The optimal ratio is 0.84 (21:25) accumulators per solar panel, and 23.8 solar panels per megawatt required by your factory (this ratio accounts for solar panels needed to charge the accumulators). 1 Answer. The number of boilers can be derived from the number of steam engines: 40 2 = 20. Sushi Belt question : r/factorio. I think it is easiest to just have an abundance of storage tanks for the steam. One pump can supply up to 20 boilers. A reactor without neighbor bonus needs 4 heat exchangers so that all its heat gets consumed. 1 electric pump can keep up with rate of roughly 10 water pumps if i recall, so at least you don't need to have pump and waterpump flows in parallel. This means a single unit of 500C steam has 5.82MW / (60/s) = 0.097 MJ of energy. This means the energy that was put into the steam to heat it to a higher temperature is wasted. Each heat exchanger converts 103 water to 103 steam, feeding 1.72 turbines. Tutorial:Main bus. -adding a second off-shore pump to start off with twice as much water (in theory); -putting in more pumps, say one pump for every underground pipe; -putting in a complete second line from off-shore pump to heat exchangers with a pump every 5 underground pipes. where game_day is the number of seconds in the game day which is 25000/60 s by default. The current optimal ratio is 1 offshore pump to 20 boilers to 40 steam engines. Optimal ratio is 1 offshore pump for every 20 steam turbines; or, 25 offshore pumps for every 291 heat exchangers. by gGeorg Sat Dec 07, 2019 1:00 am, Post So far I have built/replaced 3 reactor sectors to be on the lake rather than beside the lake, and I am pretty happy with the results (600 fewer pipes, 800 fewer underground pipes). As each heat exchanger produces 10 MW, the optimal ratio is 500 steam turbines for every 291 heat exchangers. Heat exchanger heats 15C water to 500C steam; It takes 0.2 kJ of burner energy to raise 1 water 1C; Steam is consumed by steam turbines at a rate of 60 units per second; (500C - 15C) 0.2 kJ 60 units = 5820 kW, or 5.82 MW. Create an account to follow your favorite communities and start taking part in conversations. which, given the default time lengths of: day = 12500/60 s; dawn or dusk = 5000/60 s; night = 2500/60 s, and the default: Solar_power = 60 kW; Accumulator_energy = 5 MJ = 5000 kJ, gives the optimal ratio of 0.84 accumulators per solar panel. Each boiler is capable of producing enough 165C steam for two steam generators. Heat exchangers have different dynamics to actual pipes. One steam engine consumes 30 steam per second, and one offshore pump produces 1200 water per second, so each offshore pump produces enough water to supply 40 steam engines: 1200 unit/s 30 units/s = 40. The ideal ratio is 4 Reactors, 48 Heat Exchangers, 83 Steam Turbines and 5 Water pumps. All rights reserved. Build the reactor over a lake, with careful placement of landfill you can have pumps directly feeding each end of the heat exchanger line. One offshore pump can supply 20 boilers and 40 steam engines. by astroshak Wed Jan 08, 2020 11:15 am, Post If your heat pipe is too long, your reactors will max out at 1000 C before your heat exchangers can reach a steady state of 500 C, and and you'll start to waste heat. How do you set up a reactor to get enough water to keep producing steam? If you want a ratio that's a little easier to remember, those are probably your best bet. Each heat exchanger takes a maximum input 10 megawatts of heat and uses it to heat water into steam. 40 MW of power output is consumed by 4 Heat Exchangers (10MW per Heat Exchanger ). by Honktown Mon Dec 02, 2019 1:56 pm, Post What I can't find is how much water a heat exchanger *consumes* to produce the 103ish steam per second. I get that offshore pumps produce 1200 units of water per second. Additional comment actions. by Amarula Fri Jan 03, 2020 4:45 pm, Post The maximum length of heat pipe you can use depends on the combined distance of your heat exchangers from your reactors. This link for calculations. If you overbuild reactors, you can end up wasting a lot of fuel cells without realizing it. The flow between pipes and heat exchangers is also different to pump to heat exchangers. There are mods that can add landfill tiles to existing blueprints if you're up for modding and using a blueprint rather than making your own reactor, and this design is one of my favourites - not objectively "best" perhaps, but has a certain elegance that I deeply appreciate alongside a decent serving of entirely respectable practicality. The Factorio devs plan some refactoring for the upcoming version 0.17. Change fluidbox height and base level of boiler, steam engine and pump to improve fluid flow. Heat pipes are used to transfer heat from your nuclear reactors to your heat exchangers. There are also times between day and night called dusk and dawn which complicate the calculations. by steinio Fri Jan 03, 2020 4:52 pm, Post There is a handy table on the factorio wiki listing the throughput for different lengths of pipe between pumps. and our Also, the optimal ratio is: 1 offshore pump / 14 boilers / 10 steam engines is that 10 for each boiler? Are there enough steam generators (boilers, heat exchangers)? you should have a 2 by X rectangle with one reactor dangling off the end. Stuck in a mission? Cookie Notice If I know how much energy i'm outputting from my reactors -> figure out how many turbines -> figure out how many heat exchangers -> How many pumps do I need? Hovering the mouse over a steam engine will display their current power production (Performance) and their possible power production (Available Performance), in a display on the right. The more heat exchangers you want to put on a single length of heat pipe, the shorter that heat pipe has to be to ensure minimal heat loss; e.g. This allows steam engines to be chained together. As far as I can tell, the absolute smallest perfect-ratio setup possible is: which would require an input of 1.46 uranium fuel cells per second and output a cool 46.56 gigawatts of electricity. Nuclear power plants mostly need a lot of water. Ratio of heat exchangers to turbines is 1:2, don't bother building lots of pipes for 10% les turbines. Does the game consider 1 water = 1 steam (just a different temperature?) Do your pipes have water? What does clicking on an item's icon in the "Factory" tab do? The steam production rate can also be calculated using the energy consumption: 1 Heat exchanger consumes 10MW, so it's putting 10,000,000 joule of energy into heating water/steam per second. Also, before you set it up, make sure you nuke any landfill land to get a little pollution absorption to help manage your Fun fumes cloud. If you run an odd number of reactors, you should have a 2 by X rectangle with one reactor dangling off the end. Press J to jump to the feed.

My own personal Factorio super-power - running out of power. 120 MW ^Note: Pumps, Steam Turbines and Power are approximate for easier build ratios. Final ratio: 25 offshore pumps : 291 heat exchangers : 500 steam turbines. One offshore pump can supply 20 boilers and 40 steam engines. A heat exchanger produces 10 MJ a second, therefore it produces 10MJ / 0.097MJ = 103.0927835 steam per second. 12. The technical implementation details of Factorio's pipe system still have some room for improvement. It's recommended to build them near or on bodies of water, as that lets you place offshore pumps where ever you want. In vanilla factorio, without mods which change any of these values, the optimal ratio will be the same. by leitk Mon Dec 02, 2019 4:29 am, Post by eradicator Fri Nov 29, 2019 4:43 pm, Post Hence, each water pump can support a maximum of 40 steam generators. A theory without practice is dead, practice without a theory is blind, this quote is attributed to commander Alexander Suvorov. Water: is a liquid which can be infinitely extracted from water tiles using an offshore pump; Steam: is a gas you can create by heating water in a boiler or heat exchanger; Other Factorio Guides: Boiler to Steam Ratio; Solar Panel Ratio; Console Commands & Cheats Is there any info about how much water per second Heat Exchangers use? Reddit and its partners use cookies and similar technologies to provide you with a better experience. I concur the ratio is 1:1 cerified through testing. Factorio version: 0.17 - 1.1 Downloaded by: 6.01K users Summary Adds scaled up versions in different sizes for various pipes and pumps. The heat can be used to convert water to steam using a heat exchanger and the steam can be consumed by steam turbines to produce power. So the 50,000C are enough to heat up 103 units of steam per second, since 50,000 / 485 = 103.09. If the only effect the mod has on the game is it changes the total length of one day, without changing the ratio of dusk: day: dawn: night, then the equation can be simplified as. A powered nuclear reactor outputs 40 megawatts of heat, plus an additional 40 megawatts for each powered nuclear reactor directly adjacent to it. For each 100% neighbor bonus, the reactor needs 4 more heat exchangers. Press question mark to learn the rest of the keyboard shortcuts. If not, ensure all. Click on an empty cell to place a nuclear power plant. I found the cheatsheet and wiki which have been quite helpful. Create an account to follow your favorite communities and start taking part in conversations. by Bauer Wed Jan 08, 2020 3:04 pm, Post The water calculation has me stumped. These include the power generation of a solar panel, the energy storage of an accumulator, the length of a day, and the length of a night. As shown, making the heat pipes thicker allows supporting heat exchangers that are farther away. Get some landfill to straighten the edge youre gonna use. It produces 1200 units of water per second. Also iirc tanks limit liquid throuput when it flows through them, so try connecting them on the side and not in-line if you have to at all. Espaol - Latinoamrica (Spanish - Latin America). A compendium of the most common Factorio game facts, such as build ratios, tips/tricks, . Originally posted by Alaskan Glitch: The ratio is one water pump will supply a maximum of 20 boilers with water. You can sideload water for a 1.1 GW plant. by azesmbog Fri Nov 29, 2019 4:19 pm, Post Privacy Policy. Neighbor bonuses make nuclear very efficient: 1 reactor = 40MW = 4 exchangers = 7 turbines, 2 reactor = 160MW = 16 exchangers = 28 turbines, 4 reactor = 480MW = 48 exchangers = 83 turbines. The lake under the oil field looks like a nice place, letting you place offshore pumps near the center, with the turbines extending to land. Exchanger outputs to 2 tanks. When producing power, the steam engine will display a working animation: https://wiki.factorio.com/index.php?title=Steam_engine&oldid=188232.

Community-run subreddit for the game Factorio made by Wube Software. by astroshak Sat Jan 04, 2020 1:58 am, Post Refer to Francis John play through video on YouTube on nuclear power. 6, crafting time is 15s, producing 0. This means that you need 1.428 MW of production (of solar panels) and 100MJ of storage to provide 1 MW of power over one day-night cycle. A perfect square of reactors has the highest theoretical efficiency, but at 3x3 and above you'll have reactors surrounded on all 4 sides and have no way to load the uranium fuel cells. you can put 4 heat exchangers at the end of ~135 heat pipes, but you can put 16 heat exchangers only at the end of ~50 heat pipes. Added high graphics quality option for the steam engine. Is the factory producing enough fuel (coal, solid fuel, uranium fuel cells)? This layout produces 40 MW output ( 1 SRE ). For more information, please see our You can check the usage on the turbines as well as the production stat on the offshore pump. If the player uses mods which change the power generation of solar panels, or the energy storage of accumulators, but not the length of days, a simplified version of this equation can be used. Or so. Then you just connect the reactors to exchangers and exchangers to turbines, also you need about 1 water pump per 10 exchangers (in vanilla). by Honktown Mon Jan 06, 2020 6:52 pm, Post Heat exchangers produce 103 steam/second.This can be calculated by relying on steam turbine data: A steam turbine consumes 60 steam/second and produces 5.82MW (assuming 500C steam).
