| Abstract: | Di - diversion preheater is a key equipment indigesting heat exchange of alumina production. During operation, the seal of cover found always broken, Created Seal to lose efficacy and influence on normal work of preheater. This paper introduced the cause of seal to lose efficacy, carried on reconstruction and to avoid making accident.The method was a less investment,more effective and improving on operation period. |
