Modern electricity consumption is rising, which has increased the need for better power-producing technology, particularly in emerging nations like India. The urgent need to reduce greenhouse gas emissions can be met by significantly increasing the coal-fired power stations' efficiency. The operation of a boiler that is not optimized can result in a variety of problems, including decreased boiler efficiency, increased surplus air needs, delayed combustion, increased heat rate, high CO and NOx emissions, and more. Today, every thermal power plant must priorities optimizing combustion in pulverized coal-fired boilers. The quality of the coal, the fineness of the pulverized coal, the burner tilting angle, the air fuel ratio, and the production of slagging and NOx all have an impact on the combustion in a pulverized coal fired boiler. The review of several optimisation methods has been completed.
