: Boiler is a typically complex system which is multi-input, multi-output, nonlinear as well as non-self-balanced, and
boiler combustion of power station is complex physical and chemical process. The efficiency of a boiler system is important in
several ways. Thus this work will provide the performance comparison of Briquette Boiler & Furnace Boiler of process industry
and the ways to improve its efficiency. The company is using a basic rankine cycle with an open system. The source of raw water
for boiler is pumped from the bore wells provided by HSIIDC to the reserve pond for further internal and external treatments.
These approaches are by increasing pressure, by increasing temperature and by increasing both parameters up to certain limit.
The results show that the use of increase pressure and temperature can improve boiler efficiency as well as the plant efficiency
as compared to other methods.
