【Abstract】 Weihe Chemical Fertilizer Plant originally used Huangling coal, but due to its high ash content and ash fusion point, it became an obstacle in the long term stable operation of the Texaco Gasifier. After extensive survey and study and analysis, the feedstock coal has been changed to Huating coal, which basically satisfies the requirements for long term stable operation of the gasifier. An analysis is given of the reasons for changing the feedstock coal, trial operating by using Huating coal as feedstock and results obtained, and demonstrations are presented. A method is put forward for further improvement on the slurrying property of the coal in future.更多还原
