Booming demand for electricity, especially in the developing countries, has raised power generation technologies in the headlines. At the same time the discussion about causes of global warming has focused on emissions originating from power generation and on CO2 reduction technologies such as:
(1) Alternative primary energy sources,
(2) Capture and storage of CO2,
(3) Increasing the efficiency of converting primary energy content into electricity.
In the dissertation, the thermal efficiency of the power plant is improved when Control of furnace draft (nearer to balanced draft). Oxygen level decreases percentage of flue gases. Above this level heat losses are increases & below this carbon mono-oxide is formed. Steam power plant is using fuel to generate electrical power. The used of the fuel must be efficient so the boiler can generate for the maximum electrical power. By the time the steam cycle in the boiler, it also had heat losses through some parts and it effect on the efficiency of the boiler. This project will analyze about the parts of losses and boiler efficiency. to find excess air which effect heat losses in boiler. By using the 27 MW coal fired thermal power plant of Birla Corporation Limited, Satna (M.P.) the data is collect by using types of Combustion & heat flow in boiler. Result of the analysis show that the efficiency of boiler depends on mass of coal burnt & type of combustion .This study is fulfilling the objective of analysis to find the boiler efficiency and heat losses in boiler for 27 MW thermal power plant of Birla Corporation Limited, Satna (M.P.)
