  In view of the large industrial waste heat recovery project currently in use,this paper takes the district heating project as an example to introduce the system and energy-saving research.which is used absorption heat exchanger system to recover the waste heat of the thermal power plant steam turbine and the waste heat of the cooling water.The research content as follows: Through theoretical analysis and actual operation data analysis,the influence of key factors such as waste heat enthalpy,high heat enthalpy,water supply temperature,return water temperature on the comprehensive energy efficiency of the waste heat recovery system was studied,which is summarized to improve the scope of the relevant key parameters(waste heat enthalpy,high heat enthalpy,water supply temperature,return water temperature)of the comprehensive energy efficiency of the waste heat recovery system,providing theoretical basis and guidance for the application of the waste heat recycling system project.
