Indirect method is also called as heat loss method . The efficiency is arrived at, by subtracting the heat loss fractions from 100. The standards do not include blow down loss in the efficiency determination process.  Join our WhatsApp Channel - The Indian Boiler Engineer for regular updates    Principal heat losses that take place in a boiler are listed below: •        Heat loss in dry flue gas •        Heat loss due to evaporation of water formed due to hydrogen present in the fuel •        Heat loss due to evaporation of moisture present in the fuel •        Heat loss due to moisture present in the combustion air •        Loss due to unburnt fuel in ash •        Heat loss due to radiation and other unaccounted losses Also, some heat is added to the boiler other than the f...
