Q1: What is the boiler efficiency?

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%.
