Coal Mill Pulverizers In 210 Mw Coal Base Plants

The present study aims at determining the actual performance of a coal based 210 MW power plant at full and part loads (210 MW and 195.86 MW). Design and actual performance values of boiler efficiency, specific fuel consumption, heat rate and overall efficiency are compared. During actual performance, although small deviations are

    This paper presents the thermal and economic performance of a 210 MWe coal-fired 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
