Abstract:

There are so many beam type shaft kilns in China, and most of them are cooled by heat transfer oil.This cooling method is of high consumption and high cost,but the important thing is that too much heat is discharged directly into air by radiators.Based on beam type shaft kiln production process and its operating requirements,the paper proposes a new direct steam cooling process and introduces boiler heat transfer principle into the production process of combustion beam,which realizes beam evaporative cooled and produces saturated or superheated steam output at the same time.This process has practical application value because of energy conservation and emission reduction and heat utilization.
