Why Economizer and Air Pre-Heaters are Provided in Boilers
May 03, 2009 · Boilers are provided with economizer and air pre-heaters to recover heat from the flue gases. Boilers operate with around 86 to 90% efficiency depending upon the type of fuel and design adopted. A degrease of about 20 % of boiler efficiency is seen by not providing both economizer and air pre-heaters. If economizer alone is provided then the efficiency will be …

How much coal is required to generate 1 MWH of electricity?
Mar 09, 2017 · One KW is 3600 kj per hour. Therefore, at 21% efficiency, we need a heat input of about 7,560 kj/hr (3600/21%) - therefore for producing 1 kw/hr electriccity, we need 7,560/20,000 or 0.378 kg of coal. For a megawatt/hr we would need 0.378 x 1000 = 378 kg of coal - we can round it off to 400 kg. Keyword: Industry steam boiler, boiler generate 1
