COMBINED STRUCTURE WITH SURFACE-FLAME TYPE PREMIXED COMBUSTOR AND AIR PREHEATER FOR HEAT-DRIVEN HEAT PUMP

摘要

The present invention relates to a premixed combustor and air preheater combination for a heat driven heat pump, and more particularly to a combination of a surface-flame burner and an air preheater having a plurality of concentric circular heat transfer cylindrical members. .;According to the present invention, the surface material of the pre-mixed combustor of the surface flame method is made of porous metal fibers to actively utilize radiant heat transfer from the heat pump of the combustor to the high temperature part of the combustor, thereby transferring heat from the combustor to the heat driven heat pump. To recover the heat of the discharged combustion gas as much as possible to improve combustion efficiency and thermal efficiency, and use the absorbed heat to heat the air used in the combustion process and then supply the heated air to the combustor. It is to design a surface combustion type premixed combustor and air preheater combination in which an air preheater is installed outside the combustor.
