Self-Recuperative Radiant Tube (RT)

Self-Recuperative Radiant Tube

The Hotwork Combustion Technology single-ended radiant tube incorporates a self-recuperative burner which has been designed for delayed mixing and progressive combustion to produce a highly radiant diffusion flame. This ensures uniform and high heat transfer to the outer sur face of the tube and as a consequence even temperature distribution inside the furnace. The products of combustion exhaust through the integral heat exchanger which in turn preheats incoming combustion air, thus achieving high fuel efficiencies of up to 70%. The process of heat recovery reduces the amount of fuel required by as much as 35%.
