Abstract
The combustion of gaseous fuel in radiant tube-heaters has become a common practice for the heating and chemicothermal treatment of metal. Compared to conventional flame combustion, the new method of burning a gaseous fuel in such tubes — with circulation and fluidization of the dispersed intermediate heat carrier — ensures much more rapid, uniform, and efficient heating. A study is made of the phenomenon of gravitational fluidization of heat carriers, this effect resulting in an additional intensification of heat exchange and heat transfer among the particles in such tubes.
