Abstract

Abstract: Aiming at the problems of the high operation cost, the serious abrasion of the slag conveying tubes and others of the negative pressure slag conveying system existed in the followup conveying system of drytype slag extractor, the reasons of the problems were analyzed, and the optimization scheme was proposed. The operation situation of the optimized negative pressure conveying system was compared with that of original negative pressure conveying system used in similar fossil fuel power unit, and the result shows that the optimization of the negative pressure conveying system can reduce the operation cost effectively, decrease the system maintenance working load and improve the conveying efficiency.

Key words: dry-type slag extractor, negative pressure conveying system, optimization, fossil fuel power unit
