The Theoretical Analysis And Applied Research Of Dry-type Deslagging System On Thermal Power Plant

This paper introduces the dry-type deslagging system through analyzing the status of deslagging system in Thermal Power Station.The recycle energy and the cooling air of slag were computed.The effect of the cooling air on the boiler efficiency was analyzed. In addition,the paper generalizes the advantage and disadvantage of dry-type deslagging system,and some corresponding advice was proposed.The Characteristics of the different follow-up conveying systems were studied,which would help for case choosing.Based on the technical and economic point of view,the hydraulic-type extraction system was compared with the dry-type deslagging system.It shows that the hydraulic-type extraction system has the potential to be used widely.
