How much coal a plant 500 mw she uses daily?
The following is an approximate calculation with some assumptions, as shown. A power plant of 500 MW gives the electrical power of the plant. Therefore, the actual power of … m burning coal must be determined taking into account the efficacy of the plant. A general efficiency rating for a coal-fired power plant is approximately 35%. As a result, the resulting required power to produce 500 MW of electricity is 1429 MW (500 / 0.35). 1 watt of power equals 1 Joule per second. Therefore, the plant should produce: 1429 x 106 (to convert MW to Watts) Joules per second. Then, the energy per mass of the coal must be considered. There are many types of coal with different carbon contents, and other factors, for example. Moisture content that will affect the calorific value. However, for coal for general use, a value of 37 MJ / kg is used in the example. From the above, it is possible to determine the mass of burnt coal per second. 1429000000 J / s divided by 37000000 J / kg gives a mass of 38.6 kg / s of coal that must be burned. Multiplying this number 86400 (the number of seconds in a period of 24 hours), and you get 3,337 000 kg of coal burned per day, or 3337 tonnes per day. (MORE)
