There are a lot of flue gas waste heat resources in thermal power plants,and enterprises usually use low-temperature economizer to recover flue gas waste heat.The problems of perforation,corrosion,ash accumulation and clogging in the long-term operation of traditional low-temperature economizer affect the normal recovery and utilization of flue gas waste heat.Therefore,taking a power plant of an enterprise as an example,based on the application status of low-temperature economizer,a joint recovery scheme of"low-temperature economizer of heat pipe+water heater system"was proposed.The recovery and utilization scheme of flue gas waste heat was analyzed from perspective of scheme idea,key technical principles and characteristics of the transformation.Finally,the application test of the scheme was carried out in order to realize the effective recovery of waste heat and utilization.
