Application of adjacent boiler heating technology in 1000MW ultrasupercritical thermal power units

Abstract

Abstract:

During the cold startup of a 1000MW ultrasupercritical thermal power unit in Huadian Laizhou Power Generation Company Limited, adjacent boiler heating technology is used to heat feed water of No.2 high pressure heater in hot flushing and boiler warming process, which can boost the flushing water temperature, shorten the hot flushing time and accelerate the warming of boiler. The technology can save auxiliary machinery power consumption and reduce the emission remarkably. Its environmental benefits and economic benefits are good.
