Coal Chemical Analysis - Energy engineering general , Dec 04, 2003· If you don't have one, you'll need to know the combustion process (boiler efficiency or unit heat rates, etc) and make some assumptions to derive an estimate The above is just "back-of-envolope" calculation and I'm sure there are someone who can provide a better solution
THERMAL POWER: Boiler Efficiency calculations Sep 23, 2009· For example, efficiency of a Bagasse fired boiler is about 70% where as that of oil fired boilers is about 85 % Higher moisture content in Bagasse reduces it’s efficiency So better criterion is efficiency based on LCV or NCV This is widely used in Europe and efficiency based on HHV or GCV is used in other parts of the world
THERMAL POWER PLANTS: CALORIFIC VALUE-DEFINE The calorific value or heat of combustion or heating value of a sample of fuel is defined as the amount of heat evolved when a unit weight ( or volume in the case of a sample of gaseous fuels ) of the fuel is completely burnt and the products of combustion cooled to a standard temperature of 298 degree K
