THERMAL POWER: Boiler Efficiency calculations

Sep 23, 2009 · Efficiency is a very important criterion in Boiler selection and Design. Efficiency figure depends upon the type of boiler as well as on the type of fuel and it's constituents. 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 better criterion is efficiency based on ...
