Abstract

Abstract: IGCC (Integrated Gasification Combined Cycle) is a clean and high-efficiency coal power generation technology. The stability and economy of the operation using different types of coal can be determined via the operation parameters of gasifier. Between 2014 and 2016, the comparative combustion tests of unblended coal and blended coal were carried out by stages in the gasifier of Tianjin IGCC power station. Since the kickoff of unblended coal combustion testing, the gasifier has been operated in stable condition, and the slag blocking has been significantly reduced. The operation costs of almost 14 million RMB have been saved, compared with the blended coals combustion. Therefore the feasibility of unblended coal combustion in gasifier is verified, which will provide references for future design and operation of gasifier, especially those in the IGCC stations.

Key words: IGCC power station, two-stage dry fine coal gasifier, unblended coal, blended coal
