Open absorption heat pump and application in flue gas waste heat recovering

Simple structure and low grade heat energy requirement are great advantages of open absorption heat pump. Proper use of this technology is important to solve the city heat shortage and improve energy efficiencies in industries. However，equipment corrosion，non-condensable gas and other issues often prevent the application of open absorption pump. This paper summarized the domestic and international research progressed of the open absorption heat pump. It can be used in heating，air conditioning，refrigeration and other industrial processes. Processing media including air，flue gas after combustion，driving heat source can be concentrated heat source and distributed energy，such as solar energy，biomass boiler，gas boiler and power plant boiler. Structures can be different based on heat sources and purposes of applications. Applications of open absorption heat pump in the industrial waste heat recovery，especially flue gas waste heat recovery were also briefly overviewed. The causes and possible solutions to corrosion and non-condensable gas plugging were analyzed as well.
