Ratio of heat exchangers to turbines is 1:2, don't bother building lots of pipes for 10% les turbines. Refer to Francis John play through video on YouTube on nuclear power. 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. Doubled the heat capacity of water from 0.1kJ per degree per liter to 0.2kJ. can you post a screenshot/blueprint? 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. Heat pipes (also in reactors and heat exchangers) glow with high temperatures. See also the applied power math tutorial to answer the question how much coal do I need? How do you set up a reactor to get enough water to keep producing steam? So we know that one offshore pump can supply 20 boilers but is that the same for heat exchangers? Steam engines are the most basic electricity generator, available to the player at the start of the game. By rejecting non-essential cookies, Reddit may still use certain cookies to ensure the proper functionality of our platform. You can also have some steam tanks with additional turbines for power spikes (laser turrets etc) as reactors always work with 100% power tanks will store steam when you're not using it all), Factorio Cheat Sheet - That's all the information you need. turbines, exchangers and reactor ratios will vary due to neighbor bonuses. 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. I found the cheatsheet and wiki which have been quite helpful. Do your pipes have water? 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. 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. When producing power, the steam engine will display a working animation: https://wiki.factorio.com/index.php?title=Steam_engine&oldid=188232. Pump Ratio ^ 1. Additional comment actions. The ideal ratio is 4 Reactors, 48 Heat Exchangers, 83 Steam Turbines and 5 Water pumps. 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. . by Amarula Fri Jan 03, 2020 4:45 pm, Post Press J to jump to the feed. 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? This means a single unit of 500C steam has 5.82MW / (60/s) = 0.097 MJ of energy. 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. Yogi Berra. Since heat exchangers consume 103.1 water each, a few dozen seems reasonable if . by azesmbog Fri Nov 29, 2019 4:19 pm, Post Each uranium fuel cell will power a nuclear reactor for 200 seconds. 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. As each heat exchanger produces 10 MW, the optimal ratio is 500 steam turbines for every 291 heat exchangers. This ratio is. 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. Are there enough steam generators (boilers, heat exchangers)? Includes pipe, pipe to ground, pump, offshore pump, heat pipe. by Honktown Mon Dec 02, 2019 1:56 pm, Post You can check the usage on the turbines as well as the production stat on the offshore pump. The most heat exchangers I've been able to fit on a single length of heat pipe is 30 heat exchangers on 44 heat pipes; any more than that incurs significant heat loss. But the water only gets heated up from 15C to 500C, so by 485C. 120 MW ^Note: Pumps, Steam Turbines and Power are approximate for easier build ratios. 40 MW of power output is consumed by 4 Heat Exchangers (10MW per Heat Exchanger ).

By accepting all cookies, you agree to our use of cookies to deliver and maintain our services and site, improve the quality of Reddit, personalize Reddit content and advertising, and measure the effectiveness of advertising. Optimal ratio is 1 offshore pump for every 20 steam turbines; or, 25 offshore pumps for every 291 heat exchangers. The true maximally efficient layout is a 2 by X rectangle; this gives you access to every reactor. you should have a 2 by X rectangle with one reactor dangling off the end. 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. Factorio - The Best Nuclear Power Ratio To generate ten fuel cells, you will need one U-235 cell and nineteen U-238 cells. What I can't find is how much water a heat exchanger *consumes* to produce the 103ish steam per second. Don't know how to use a machine? 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. Is the factory producing enough fuel (coal, solid fuel, uranium fuel cells)? This page was last edited on 13 September 2019, at 23:48. Then have a simple trigger than turns your nuclear plant on and off based on the storage tank steam levels. In theory, there is no difference between theory and practice. Reddit and its partners use cookies and similar technologies to provide you with a better experience. This can be extended as far as you want; every additional 2 reactors will provide an additional 320 megawatts of heat output. In vanilla factorio, without mods which change any of these values, the optimal ratio will be the same. All rights reserved. Electricity has to be produced before it can be transferred to consumers over the electric system. In practice, there is. HolyGarbage . (Low quality because reddit wouldn't let me upload the full png) redditads Promoted. So a 2x2 block produces 480MW (4*3*40). A heat exchanger produces 10 MJ a second, therefore it produces 10MJ / 0.097MJ = 103.0927835 steam per second. 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. A heat exchanger consumes 10 MW. 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. Introduction Troubled by pipes having low flow rates? An offshore pump produces 1200 units of water per second, which is enough for 116.4 MW. This layout produces 40 MW output ( 1 SRE ). By rejecting non-essential cookies, Reddit may still use certain cookies to ensure the proper functionality of our platform. and our You may also use this to rectify brownouts/blackouts. Does the game consider 1 water = 1 steam (just a different temperature?) A compendium of the most common Factorio game facts, such as build ratios, tips/tricks, . Using steam engines for power does not produce pollution, however using boilers to heat up the water does. 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. by gGeorg Sat Dec 07, 2019 1:00 am, Post by mrvn Wed Jan 08, 2020 3:42 pm, Post One pump can supply up to 20 boilers. 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. Tutorial:Main bus. 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. Stuck in a mission? 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. Thus, they can buffer 500 MJ of heat energy across their working range of 500C to 1000C, and require 485 MJ of energy to warm up from 15C to 500C when initially placed. 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 turbine consume 60 water/s so 1200/60=20 turbines. 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). by astroshak Wed Jan 08, 2020 11:15 am, Post u/asdjfsjhfkdjs calculated the convergents of 500:291, and found that 7 : 4 and 55 : 32 are both fairly accurate approximations. 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. This page was last edited on 27 October 2020, at 13:19. 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. Factorio version: 1.1 Downloaded by: 1.88K users WHAT IS OFFSHORE P.U.M.P.S.? 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. This means the energy that was put into the steam to heat it to a higher temperature is wasted. These fuel cells are then burned in a nuclear reactor to create heat. (Except that you can potentially turn 8 gigajoules of uranium fuel cell into 40 gigajoules of heat. -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. That's actually just odd. Reddit and its partners use cookies and similar technologies to provide you with a better experience. Community-run subreddit for the game Factorio made by Wube Software. 75 crafting speed, while the induction furnaces use 3 * 1, so the ratio could be fine tuned a bit. It produces 1200 units of water per second. Yes, there is also a maximum throughput for water that depends on the distance the . To heat up 1 unit of water 1 degree, 200 joules are needed, so the heat exchanger is heating up water by 50,000C in total. This allows steam engines to be chained together. Mark IIIs are unable to complete a full cycle without going into meltdown and thus need to be shutdown mid-cycle in order to deal with the high amount of excess heat. where game_day is the number of seconds in the game day which is 25000/60 s by default. Or so. Valve Corporation. using 3 pumps and a tank, you can feed 28 heat exchangers. Designed for supporting scaled up machines from "Schall Machine Scaling" mod. There's no clear ratio as you need to account for heat bonus from other reactors but it's quite easy to calculate yourself, if you fuel the reactors it will show you produced heat in MW (with bonus) you just sum up all reactors and divide by heat exchanger power (all power/power per 1 hear exchanger) to get the number, then you do the same for turbines (all power/power per 1 turbine). So a heat exchanger generated 103 steam per second is 103 water per second I need from my offshore pump. Press J to jump to the feed. 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. SmartAlec105 having more than 2 steam engines per boiler could do that. 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. The heat exchanger exchanges heat between a heat connection and water to produce steam . 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. Do the numbers in the "beacons" column represent the number of modules or the number of beacons? Doubled the heat capacity of water from 0.1kJ per degree per liter to 0.2kJ. 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). One offshore pump can supply 20 boilers and 40 steam engines. All trademarks are property of their respective owners in the US and other countries. The flow between pipes and heat exchangers is also different to pump to heat exchangers. 20. Then you just connect the reactors to exchangers and exchangers to turbines, also you need about 1 water pump per 10 exchangers (in vanilla). The Factorio devs plan some refactoring for the upcoming version 0.17. You can sideload water for a 1.1 GW plant. Post Ratio of reactors to whatever is 2x2 480MW reactor to 10MW heat exchanger, ratio of reactors to miners is 1:4 iirc, so double that miners. The offshore pump produces water from a lake or ocean. by mrvn Wed Jan 08, 2020 3:45 pm, Powered by phpBB Forum Software phpBB Limited. Each offshore pump outputs 1200 units of water per second. Tileable Nuclear Reactor Design. Each heat exchanger takes a maximum input 10 megawatts of heat and uses it to heat water into steam. For each 100% neighbor bonus, the reactor needs 4 more heat exchangers. If you want a ratio that's a little easier to remember, those are probably your best bet. Heat exchangers have different dynamics to actual pipes. Heat pipes are used to transfer heat from your nuclear reactors to your heat exchangers. 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. Additional comment actions. 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. 412.36 Water requires 1 ( 0.34) Offshore Pumps (1200 per Offshore Pump ). The heat exchanger exchanges heat between a heat connection and water to produce steam. There are also times between day and night called dusk and dawn which complicate the calculations. r/factorio . Sushi Belt question : r/factorio. Build the reactor over a lake, with careful placement of landfill you can have pumps directly feeding each end of the heat exchanger line. Give exchanger max heat you can then let the exchanger turn 25k water into steam. by disentius Fri Nov 29, 2019 9:15 pm, Post All rights reserved. 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). All trademarks are property of their respective owners in the US and other countries. Neighbor bonuses make nuclear very efficient: 1 reactor = 40MW = 4 exchangers = 7 turbines It takes 200J to heat 1 unit of water by 1C. My own personal Factorio super-power - running out of power. And probably how many Offshore Pumps you need for them?

The glow of the heat pipes indicates temperature, with left ends being at the upper limit of 1000C. by mrvn Fri Nov 29, 2019 4:41 pm, Post 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. by Bauer Wed Jan 08, 2020 3:04 pm, Post So the 50,000C are enough to heat up 103 units of steam per second, since 50,000 / 485 = 103.09. Change fluidbox height and base level of boiler, steam engine and pump to improve fluid flow. 15 - Factorio Factorio Forums View topic - 0. Privacy Policy. The steam produced is exactly 500C hot, even if the exchanger is hotter. (Except that you can potentially turn 8 gigajoules of uranium fuel cell into 40 gigajoules of heat. There is a handy table on the factorio wiki listing the throughput for different lengths of pipe between pumps. Heat exchangers will not produce steam until they reach 500C. A steam turbine consumes 60 units of steam per second, which is 5.82 MW. A theory without practice is dead, practice without a theory is blind, this quote is attributed to commander Alexander Suvorov. by astroshak Sat Jan 04, 2020 1:58 am, Post There are multiple methods to produce electricity: Each steam engine needs 0.5 boilers when running at full capacity. Press question mark to learn the rest of the keyboard shortcuts. Now you have 0 waste of fuel. Heat exchangers are pipes too. Nuclear power plants mostly need a lot of water. The maximum length of heat pipe you can use depends on the combined distance of your heat exchangers from your reactors. Until then it is advisable to not use more than one pump per water network. This page was last edited on 16 February 2022, at 11:27. The technical implementation details of Factorio's pipe system still have some room for improvement. https://wiki.factorio.com/index.php?title=Heat_exchanger&oldid=175988. 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. As shown, making the heat pipes thicker allows supporting heat exchangers that are farther away. They represent the number of modules. Factorio version: 0.17 - 1.1 Downloaded by: 6.01K users Summary Adds scaled up versions in different sizes for various pipes and pumps. 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). 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. A heat exchanger produces 10 MJ a second, therefore it produces 10MJ / 0.097MJ = 103.0927835 steam per second. A powered nuclear reactor outputs 40 megawatts of heat, plus an additional 40 megawatts for each powered nuclear reactor directly adjacent to it. by Amarula Mon Dec 02, 2019 3:51 pm, Post Click on an empty cell to place a nuclear power plant. 1 offshore pump: 20 Steam Turbines. Geplaatst op 3 juli 2022 door . It takes 200J to heat 1 unit of water by 1C. by Honktown Fri Jan 03, 2020 8:34 pm, Post Looking for efficient setups? Hence, each water pump can support a maximum of 40 steam generators. One Offshore pump can fully supply 12 (11.64) . by steinio Fri Jan 03, 2020 4:52 pm, Post 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. 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.
