Statistical modeling of an integrated boiler for coal ...
2019-9-27 · The thermal power plant produces power by converting thermal energy tomechanical energy and from mechanical energy to electrical energy. Thermalenergy is generated in the boiler section which consists of furnace, economizer,drum, superheater and reheater. Correct proportion of the coal and air are given tothe furnace for the complete combustion of the coal to produce flue gas. Theobtained hot flue gas from this unit transfers heat to all the other units of boiler asshown in Fig. 1. Meanwhile, feedwater enters the economizer unit for thepreheating purpose. The preheated liquid enters drum unit for the conversion ofliquid to steam. Drum unit in turn comprises of downcomer, riser and a drum.Downcomer transfers hot water from economizer and riser, where the conversionof water to unsaturated steam takes place. The steam and the droplets of water fromthe unsaturated steam are separated in the upper and lower part of the drum unitrespectively. The steam …
