boiler can alter the heat transfer rates, the wall and tube temperatures and the boiler efficiency. Fortunately, NG possesses combustion properties which make possible its use in coal- or oil-fired boilers with minimal effects on the boilers' performance. There are few examples of the use of NG in oil-fired boilers…

1. ENERGY PERFORMANCE ASSESSMENT OF BOILERS

Abstract— An energy audit is feasibility study to establish and quantify the cost of various energy inputs to and flows within a factory or an organization in a given period. Energy Audit of Coal Fired Thermal Power Plant has been considered out. The aim is to calculate all the losses and give measures to rectify them and calculate the economic benefits after taking measures of rectification of losses. The Energy Audit …
