MATHEMATICAL MODEL AND ALGORITHM FOR CALCULATION OF THERMAL STATE OF A REGENERATOR ACCUMULATING CONVERTER GAS HEAT OF COMBUSTION AND HEATING AIR FOR A RECOVERY BOILER

Abstract

The heat of combustion of the converter gas, which is periodically formed in the oxygen-converter production at the metallurgical plant, is proposed to be used for alternate heating of the checkerwork of two regenerators (such as сowpers), and their alternate cooling by a continuous flow of air heated to a high temperature, and directed to the recovery boiler to generate steam. A mathematical model is presented that allows evaluating the thermal state of the regenerator, the temperatures of the heating gases and the heated air in the modes of heating and cooling the regenerator checkerwork. An algorithm for numerical calculation of the temperature fields of the regenerator checkerwork, gases and air is presented.
