Abstract: In order to investigate the adaptability of dry pulverized Gasification for Shenhua coal in HT-L gasifier, this paper systematically analyzes and summarizes the quality characteristics and gasification characteristics of the coals used in HT-L gasifier. Taking three Shenhua coals from Yanjiata, Daliuta and Batuta as the research objects, the industrial analysis and ash melting characteristics of these coals are compared with the feed coals for HT-L gasifier. The results show that the bituminous coals are favourable used in HT-L Gasififer via the pressurized gasification technology of pulverized coal. The anthracite coal with high ash melting point can be used in HT-L Gasififer via adding fluxing agent or mixing other coal. The three kinds of Shenhua coals have the characteristics of bituminous coal with high volatile matter, high calorific value, low ash and low sulfur. Base on the industrial analysis, these Shenhua coals meet the coal quality requirements of HT-L Gasififer. However, the adaptability of the Shenhua coals from Daliuta and Batuta for HT-L gasifier need to be improved by mixing with other coal, for the reason that the ash melting points of these Shenhua coals are relatively lower.
