how to calculate boiler efficiency

Modern Method to deterMine recovery Boiler efficiency

In a simple boiler process, the fuel and the required amount of combustion air are fed into the boiler. The fuel reacts with the oxygen in the boiler and the fluegas is drawn out. The released heat is captured to the water pumped into the boiler which transforms it to the steam that flows from the boiler.

How does one calculate boiler efficiency? - Quora

The boiler efficiency is a rain of the chemical energy in the natural gas versus the amount of energy put out by the boiler. You will need to know the amount of gas fed into the boiler as well as the thermal energy imparted onto the water flowing through the boiler. Keep your units of measure to be consistent.
