According to the China Chemical Industry News and Tianqing Company, “After two months of load-testing, the maximum load achieved in tests on single coal-crushing pressurized gasification units was 10,000 Nm3/h, setting a record for the operational load of such units in China.” ”On September 8, the production manager of Henan Jinmei Tianqing Coal Chemical Co., Ltd. told a reporter from China Chemical Industry News. Jinmei Tianqing Company has a total of 6 coal crushing and pressurized gasification units, which use coal from Block 15 in Jincheng as raw material to produce crude gas for use in subsequent processes to manufacture synthetic ammonia, urea, and natural gas. It is understood that the coal from block 15# in Jincheng is high-rank coal; it has a high degree of coalification, with a volatility content of around 7%. Its fixed carbon content is high, generally not less than 72%, while the ash content is low, usually not exceeding 20%. However, the sulfur content is relatively high, reaching 2.5%, and in some cases as high as 4.5%. At the same time, 15# anthracite coal has a high ash fusion point, generally not less than 1450°C. In order to achieve more economical production costs, Jincheng Coal Tianqing Company conducted tests to increase the single-furnace load of the coal gasification furnace at 4.0 MPa on the No. 15 coal seam in Jincheng during July and August this year. During the height-reaching test, Jinmei Tianqing Company closely monitored every stage of the production process, starting from the inspection of raw materials upon arrival at the plant, screening before they were fed into the furnace, process adjustments after feeding into the furnace, and tracking of the operations in subsequent stages, to ensure the smooth progress of the test. During the testing process, the gasification furnace operated stably, with all parameters within normal ranges. The gas composition improved significantly, and the steam decomposition rate increased markedly, resulting in good test outcomes: at an oxygen load of 10,000 Nm3, the output of raw gas per furnace reached 60,000 Nm3/h, which is 150% of the designed value ； The proportion of useful gases (CO+H2) in the raw gas can reach 70%, which is more than 10% higher than the designed value of 60% ； The CH4 content is 8.06%, which is 2.29% higher than the designed value; the content of useful gas components in the crude gas during actual operation has increased significantly, resulting in a substantial improvement in carbon utilization efficiency.
