recuperator tube by Qingdao Hexin Machinery Co.,Ltd.
Radiant tube insertion type heat exchanger, the gas discharged from the maximum degree of preheating combustion supporting air, to improve the heat transfer efficiency maximum.
The radiation tube heat exchanger can effectively reduce the flue gas temperature, the temperature of the outer surface of the heat exchanger is below 80 degrees Celsius, does not need additional insulation material to heat insulation.
Other than the regular radiant tubes of W-type,U-type and I-type , we also customized various of special shape radiant tubes according to the request of the customers drawings or furnace type, like S type, O type, P type and more.
