The utility model is compared with prior art and is had the following advantages:
1, the utility model adopts the spray and radiation heat transfer technology, heat exchange of heat pipe superconduction phase-change heat-exchange heated hot air heated is impacted high-temperature burner hearth and anti-quirk heat-transfer surface from the vertical high speed jet of jet flow tube spray orifice after the pressurization of hot blast air-introduced machine, significantly reduce the boundary-layer of the anti-quirk outer wall of burner hearth heat-transfer surface, reduce heat transfer resistance greatly, improve heat transfer intensity, reduction hearth wall surface temperature that can be bigger prolongs burner hearth service life, and the coefficient of heat transfer can reach 52-64W/m simultaneously
2℃ be 1.5～2 times of radiation recuperator, and hot blast temperature can improve about 1 times.
2, the utility model is earlier through the heat exchange of heat pipe heated hot air heated, and again through the jet radiation heat-exchanger impingement heat transfer, the hot-blast stove heat exchange efficiency can reach 90%, and hot blast temperature can reach 500-600 ℃; Adopt flue gas recirculation utilization and spray and radiation heat exchange.Can reduce burner hearth wall surface temperature about 50%, so just can adopt common steel alloy to make hot-blast stove, save manufacturing cost.
