  • Efficiency of a Coal Fired Boiler in a Typical Thermal

    This paper presents briefly on the boiler efficiency evaluation procedures by direct and indirect methods useful in thermal power plants. In the direct method consideration is given to the amount of heat utilized while evaluating the efficiency of the boiler, whereas, indirect method accounts for various heat losses. The boiler efficiency evaluated by direct method is found to be lower than
