Article

The thermal state of a cap-type gas distributor with active thermal insulation in the form of a ventilated granular bed is modeled. The temperatures of air at exit from the granular bed and of the upper gas-tight plate of the gas distributor have been calculated by the method of successive approximations. The efficiency of active thermal insulation that substantially reduces the gas distributor temperature and simultaneously serves as a preheater for the primary air entering into the high-temperature fluidized bed is shown.
