If you are doing a project which requiresparts to function in extreme heating 1,200 °F, you should be having a heat resistant casting. It’s essential to know, that every heat resistant goods arenot similar but different. There are many element that go into predicting thatwhich component is better for your specific industry. Radiant tubes are one ofthe many different types of heat resistant products available.What are RadiantTubes?The procedure of heating system do notonly depends on the furnace burner, but mainly on the radiant tubes. Tubes are categorised according to their construction. Heat is passed by radiation from the outer surface of the heated tube to the internal surfaces being heated.
Different sizes and shapesof various heat opposing substances are used for these tubes depending upontheir particular need, service temperature, and furnace atmosphere. What is W-TYPE Radiant Tube?A radiant tube heating consist of anexternal radiant tube build-up of heat-resistant substance, burner assemblycomprising an inner tube situated within and spaced inwardly from said radianttube, said inner tube having a forward discharge end, means for transferringcombustion air into said internal tube for flow toward the forward end of saidinner tube, a gas supply pipe located within said inner tube and having aforward end, means for delivering gaseous fuel to said gas supply pipe.Radiant tube assemblyThe current concept is a radiant tube assembly thatinvolves a burner assembly firing combustion gases into a combustion tube whoreleases radiant heat energy from its external surface. A black ceramic coatingis applied to the external surface of the combustion tube to increase theemissivity of the combustion tube and lower the temperature of the externalsurface of the combustion tube. Semi-circular top and semi-circular bottominserts extending longitudinally along the length of a first section of thecombustion tube lower the combustion tube outer temperature.
