1. ENERGY PERFORMANCE ASSESSMENT OF BOILERS Bureau of Energy Efficiency 1 1.1 Introduction Performance of the boiler, like efficiency and evaporation ratio reduces with time, due to poor combustion, heat transfer fouling and poor operation and maintenance. Deterioration of fuel quality and water quality also leads to poor performance of boiler.
The direct method testing is also sometimes referred to as input-output method. This method estimates the boiler efficiency using the heat added to the steam and the gross heat in the fuel. Formula: Boiler Efficiency % = ( Heat Output / Heat Input ) x 100.
