Efficiency of a Coal Fired Boiler in a Typical Thermal

A coal-fired thermal power plant. The combustion air will be supplied to the burners by the forced-draft fan, and pre-heated the air to dry the pulverized coal. Mixture of the fuel and air will be burned in the furnace. From combustion, the heat recovered by the boiler generates steam at the specified pressure and temperature.
