Uticaj kvaliteta uglja na ostvarenu snagu generatora termoelektrane nazivne snage 300 MW

Abstract

This paper discusses the results of monitoring the operation of the steam-turbine unit of the 300 MW thermal power plant over a period of 2 months. During the monitoring, coal samples were taken in front of the mill-fan (3 samples/day) and data were collected on the fuel load of the boiler, temperatures in the boiler, temperatures of flue gases, content of pollutants in flue gases and realized gross power on the generator. Based on the results of technical analyses of coal and collected data on the operation of the block, direct dependencies were established between the quality of coal expressed through the Lower Thermal Power (DTM) value, and the realized gross electric power on the generator, coal consumption and the content of pollutants in the flue gases of the thermal power plant.
