Regulation of Corncob on Ash Melting Characteristics of Xinjiang Piliqing Subbituminous Coal
A lot of biomass waste will be produced in daily life.In order to make full use of these waste biomass,this paper studies coal gasification after mixing biomass ash with Xinjiang piliqing subbituminous coal(PSBC)ash.After adding corncob ash,the ash fusion temperature of PSBC is determined,and mixed ash samples are prepared with different proportions of coal.With the help of HR-4A microcomputer ash melting point tester,the effect of biomass ash on the fusion characteristics of PSBC ash was determined.The results show that the ash fusion temperature of PSBC can be reduced by adding different proportion of biomass,but the results show different trends.Factage7.2 software was used to analyze various minerals such as low melting point xonotlite,potassium carbonate,and high melting point calcium oxide after mixing biomass with coal.According to the change of minerals,the reason for the change of ash fusion temperature of PSBC was analyzed.
