ON THE THERMAL REGIME OF THE PROTECTIVE GRANULAR BED OF A GAS DISTRIBUTOR

A numerical solution of a two-temperature problem on the thermal state of an aerated granular bed, constituting the thermal protection of the gas distributor of a high-temperature bubbling bed, is carried out. An equation is obtained for the coeffi cient of the effi ciency of cooling the gas distributor. It is shown that on the side of the bubbling bed the surface temperature of the granular bed is independent of its thermal conductivity and thickness
