Experimental Research of Enhancing Heat Transfer Performances of the Radiant Tube in Gas-fired Radiant Heating System

摘要：

This paper studies the subject of enhancing radiation heat transfer performances of radiant tube in a Gas-fired Radiant Heating system through experiments.Two methods are mainly discussed: the first is that high efficient radiant material is brushed on the surfaces of the radiant tube.The second method is that radiations are implanted in the radiant tube.The experimental results show that the two methods both have roles in enhancing radiation heat transfer performances,but the degree of impact is different.If the two methods are combined,the radiation heat transfer efficiency will be enhanced more obviously.

关键词： Gas-fired radiant heating system Radiant tube High efficient radiant material Radiation
