The feasibility study on the key technology of slurry flash for heat supply is carried out for Unit 1 of a power plant,taking the HG-1125-25.4-HM2 boiler that has already been put into operation as the re-search object.On the basis of wet flue gas desulfurization system,a slurry vacuum flash system and a heat pump system are additionally provided.Part of the desulfurized slurry is pumped into the vacuum flash sys-tem,and then transferred into the desulfurizing tower for spray desulfurization after the slurry is flashed and cools down,for the purpose of absorbing the heat of flue gas and increasing the heat temperature.Besides,the impacts of other processes in the plant are simultaneously studied and analyzed,and the benefit is calcu-lated,in order to get the profits from heat supply and coal saving under the corresponding load.
