Boiler Efficiency Testing Objectives

utilized to generate steam. There are two methods of assessing boiler efficiency: 1) Direct Method: In this method the energy gain of the working fluid (water and steam) is compared with the energy content of the boiler fuel. 2) Indirect Method: In this method the efficiency is the difference between the losses and the energy input.

Field Test of Boiler Primary Loop Temperature - Energy

Boiler Efficiency = (%) (Fuel consumption per hour :kg) × (Fuel low calorific heating value : kJ/kg) h2: The ratio enthalpy of feed water (kJ/kg) h1: The ratio enthalpy of steam (kJ/kg) The initial value of boiler efficiency for Z Boiler is depending on the boiler type, but it is normally 80-88%.
