摘要: 闡明中小型高爐的風溫由1000 ℃左右提高到1250-1300 ℃的主要措施是將煤氣與空氣雙預熱;提出應用高速燒嘴和新型外燃旋流熱風爐來預熱助燃空氣,燒單一煤氣可以實現高爐1250～1300 ℃高風溫.對爐內流動與傳熱過程進行的數值計算結果表明,在蓄熱球床表面沒有偏流,氣流及溫度分布均勻.在中試爐上測量的煙氣溫度分布與計算結果基本吻合.

Abstract: It is clarified that the important method to improve the blast temperature from 1000 ℃ to 1 250-1 300℃ is to preheat both auxiliary air and coal gas. The blast furnace temperature can be reached to 1250-1 300℃ by burning single blast stove gas if using high speed burners and a type of external-combustion swirl-flowing hot blast stove to preheat auxiliary combustion air. The calculating results, similar to those determinating experimental data in a middle experiment hot blast stove, proved that there is no eccentric flow in the face of the store energy balls and the flow and temperature fields even.
