Each plant is fired with subbituminous coal from the powder river basin (PRB) (see Table for coal properties) and sized to generate 750 MW of net power. The flue gas temperature exiting the air heaters of all four boilers is 121 °C (250 °F) and the boiler efficiency is % (HHV).
A coalfired thermal power station is a power plant in which the prime mover is steam driven. Water is heated, turns into steam, and spins a steam turbine, which drives an electrical generator, as schematically shown in Fig. it passes through the turbine (one to three stage), the steam is condensed in a condenser and recycled to where it was heated; this is known as a Rankine cycle.

With a total generating capacity of 2,600 MW, Gavin Plant ranks as the largest generating station in the state of Ohio. It is located along the Ohio River at Cheshire, Ohio, and has an average daily coal consumption of 25,000 tons at full capacity. The coal arrives by barge and is stored in the plant''s coal .
This paper presents the thermal and economic performance of a 210 MWe coalfired power plant situated in North India. Analysis is used to predict coal consumption rate, overall thermal efficiency, mass flow rate of steam through boiler, and Net present value (NPV) of plant for given load. Thermodynamic analysis was carried out using mass and energy equations followed by empirical correlations.
