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.
Oct 23, 2013 · Combustion efficiency is dependent upon using the right amount of air to consume the fuel. In fuel-fired process heating, the largest source of energy loss is through the exhaust stack, which is why managing air flow is essential to combustion efficiency. When fuel burns in the presence of oxygen it is converted to carbon dioxide, water and heat.
The variation in boiler furnace size can upset the performance drastically. Oil and gas fired units have more uniform sizes, but the coal fired units have large variation.
