It takes 200J to heat 1 unit of water by 1C. by Amarula Fri Jan 03, 2020 4:45 pm, Post They only work when they're above 500 C, and have a maximum temperature of 1000 C. Temperatures above 500 don't increase efficiency; the exchanger will just store the heat, which it can then use later. 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. Introduction Troubled by pipes having low flow rates? 9.89 gigawatts is a lot. 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. One offshore pump can supply 20 boilers and 40 steam engines. If you overbuild reactors, you can end up wasting a lot of fuel cells without realizing it. Reddit and its partners use cookies and similar technologies to provide you with a better experience. EDIT NOTE: The original version of the post used the wrong output for steam turbines (5.8 MW instead of 5.82). I get that offshore pumps produce 1200 units of water per second. by Honktown Tue Jan 07, 2020 10:30 pm, Post by mrvn Fri Nov 29, 2019 4:41 pm, Post Id probably put it on or next to either of the lakes in the middle north or middle south. This means the energy that was put into the steam to heat it to a higher temperature is wasted. Each offshore pump outputs 1200 units of water per second. The true maximally efficient layout is a 2 by X rectangle; this gives you access to every reactor. Neighbor bonuses make nuclear very efficient: 1 reactor = 40MW = 4 exchangers = 7 turbines There is a handy table on the factorio wiki listing the throughput for different lengths of pipe between pumps. Click on an empty cell to place a nuclear power plant. A compendium of the most common Factorio game facts, such as build ratios, tips/tricks, . This link for calculations. Then you just connect the reactors to exchangers and exchangers to turbines, also you need about 1 water pump per 10 exchangers (in vanilla). factorio offshore pump heat exchanger ratio It produces 1200 units of water per second. If you want a ratio that's a little easier to remember, those are probably your best bet. (Except that you can potentially turn 8 gigajoules of uranium fuel cell into 40 gigajoules of heat. Stuck in a mission? When producing power, the steam engine will display a working animation: Get some landfill to straighten the edge youre gonna use. 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 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. by Honktown Mon Jan 06, 2020 6:52 pm, Post Looking for efficient setups? Exchanger outputs to 2 tanks. Community-run subreddit for the game Factorio made by Wube Software. This produces the 1:20:40 ratio. Someone already mentioned the normal "build on a lake" strategy. 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). chrisgbk 6 yr. ago Technically the HX consumes the water and outputs an equal amount of steam. fox hill country club membership cost. Hence, each water pump can support a maximum of 40 steam generators. by Amarula Mon Dec 02, 2019 3:51 pm, Post There are multiple methods to produce electricity: Each steam engine needs 0.5 boilers when running at full capacity. (Low quality because reddit wouldn't let me upload the full png) redditads Promoted. 75 crafting speed, while the induction furnaces use 3 * 1, so the ratio could be fine tuned a bit. Then have a simple trigger than turns your nuclear plant on and off based on the storage tank steam levels. HolyGarbage . 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. Community-run subreddit for the game Factorio made by Wube Software. 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. So a heat exchanger generated 103 steam per second is 103 water per second I need from my offshore pump. Added high graphics quality option for the steam engine. You can check the usage on the turbines as well as the production stat on the offshore pump. The flow between pipes and heat exchangers is also different to pump to heat exchangers. Steam engines will automatically adjust their power production and steam usage based on the current demands of the electricity network. Heat pipes (also in reactors and heat exchangers) glow with high temperatures. 20. 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. 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. So you have 10 + 12 = 22 pipes. The steam produced is exactly 500C hot, even if the exchanger is hotter. using 3 pumps and a tank, you can feed 28 heat exchangers. Cookie Notice 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). That's actually just odd. Is steam able to reach all steam engines? Final ratio: 25 offshore pumps : 291 heat exchangers : 500 steam turbines. 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. Factorio version: 1.1 Downloaded by: 1.88K users WHAT IS OFFSHORE P.U.M.P.S.? The optimal ratio of accumulators per solar panel relies on many values in the game. (Except that you can potentially turn 8 gigajoules of uranium fuel cell into 40 gigajoules of heat. An offshore pump produces 1200 units of water per second, which is enough for 116.4 MW. So I've run into an issue with water for my Turbines. All rights reserved. Optimal ratio is 1 offshore pump for every 20 steam turbines; or, 25 offshore pumps for every 291 heat exchangers. 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. 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. and another post in that thread (which calculates the solar panel to megawatt ratio in a different way). 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. The glow of the heat pipes indicates temperature, with left ends being at the upper limit of 1000C. Each boiler is capable of producing enough 165C steam for two steam generators. 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. If you run an odd number of reactors, you should have a 2 by X rectangle with one reactor dangling off the end. 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. Since steam is produced from water in a 1:1 ratio, this also means that 103 units of water are consumed per second. 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). One exchanger 3 storage tanks plus inf heat. Pump Ratio ^ 1. The heat exchanger exchanges heat between a heat connection and water to produce steam. 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. Here are the total requirements for certain amounts of reactors, with everything rounded up to guarantee maximum energy production. The current optimal ratio is 1 offshore pump to 20 boilers to 40 steam engines. By rejecting non-essential cookies, Reddit may still use certain cookies to ensure the proper functionality of our platform. Originally posted by Alaskan Glitch: The ratio is one water pump will supply a maximum of 20 boilers with water. For more information, please see our Also, the optimal ratio is: 1 offshore pump / 14 boilers / 10 steam engines is that 10 for each boiler? Create an account to follow your favorite communities and start taking part in conversations. Privacy Policy. Heat exchangers will not produce steam until they reach 500C. 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. turbines, exchangers and reactor ratios will vary due to neighbor bonuses. There are also times between day and night called dusk and dawn which complicate the calculations. Heat pipes are used to transfer heat from your nuclear reactors to your heat exchangers. This layout produces 40 MW output ( 1 SRE ). by leitk Mon Dec 02, 2019 4:29 am, Post 12. fox hill country club membership cost. you should have a 2 by X rectangle with one reactor dangling off the end. factorio offshore pump heat exchanger ratio A heat exchanger consumes 10 MW. 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. Doubled the heat capacity of water from 0.1kJ per degree per liter to 0.2kJ. Post by disentius Tue Jan 07, 2020 9:36 pm, Post by Amarula Fri Nov 29, 2019 3:09 pm, Post Finally, after 20 hours of work, I present the flowchart for Pyanodon Space Science! Designed for supporting scaled up machines from "Schall Machine Scaling" mod. 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. Valve Corporation. All trademarks are property of their respective owners in the US and other countries. 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. The maximum length of heat pipe you can use depends on the combined distance of your heat exchangers from your reactors. It takes 200J to heat 1 unit of water by 1C. 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. u/asdjfsjhfkdjs calculated the convergents of 500:291, and found that 7 : 4 and 55 : 32 are both fairly accurate approximations. by Bauer Wed Jan 08, 2020 3:04 pm, Post Note: This is ONLY to be used to report spam, advertising, and problematic (harassment, fighting, or rude) posts.
