• ### Boiler Efficiency Introduction and Calculation Methods-ZBG

What is boiler efficiency. Boiler efficiency is a combined result of efficiency of different components of a boiler. A boiler has many sub systems whose efficiency affects the overall boiler efficiency. Couple of efficiency which finally decide the boiler efficiency are- combustion efficiency and thermal efficiency.
