Abstract

Abstract: The paper introduces aircooled drytype deslagging system applied more in large size power plant boiler in recent years. Comparative tests on drytype and wettype deslagging system were done. By contrasting boiler exhaust gas temperature, combustible ash content and boiler efficiency, the effect of drytype deslagging system on boiler is given, and this provides a reference for deslagging system choice in large unit.

Key words: dry-type deslagging, wet-type deslagginy, exhaust gas temperature, boiler efficiency, combustible ash
