China Drying Network News China's independently developed chilled process dry pulverized coal gasification technology has successfully realized industrial applications. On August 31, the 300,000-ton/year methanol plant with the first domestic chilling process 1000-ton pulverized coal gasification furnace was successfully put into operation and crude methanol was produced at Wusinqi Shilin Chemical Co., Ltd., Ordos, Inner Mongolia. get through. As of the time of the press release on September 10, the device has been operating stably for 10 days. It is reported that this is the chilled process dry coal pulverized flow entrained bed gasification device with the largest amount of coal in a single furnace that is independently developed at home. According to reports, the 300,000-ton/year methanol plant has a daily coal input of 1,000 tons, a gasifier pressure of 4.0 megapascals, a gasification temperature of 1400°C to 1600°C, and a carbon conversion rate of over 99%. The product gas is clean and the specific oxygen consumption is lower. It is 300 standard cubic meters/1000 standard cubic meters. The cold gas efficiency is 77% to 83%. According to Ren Yongqiang, head of the Green Coal and Power Department of Huaneng Group Clean Energy Technology Research Institute Co., Ltd., the two-stage dry pulverized coal gasification technology developed by Huaneng Group has obtained national invention patents for its overall process and key technologies and was once listed as a national "863" plan key projects in the field of energy. The technology uses dry coal powder to feed two sections up and down, and the coal has a wider adaptability. The pulverized coal gasification divides the chilling process and the waste pan process. Among them, the dry pulverized coal gasification and chilling process adopts the lower-stage feed, the upper spray water quenches, and the secondary cooling of the chilled tank is used after the steering, which eliminates expensive, high-failure waste boilers, ceramic filters, and chilled air. Compressor, less number of gasifiers, less maintenance work, and large steam production, can effectively improve the stability of the operation. In April of this year, dry pulverized coal flow entrained gasifier with the largest amount of coal to be used for single boilers developed using dry pulverized coal gasification technology has been successfully applied to the 250MW integrated coal gasification combined cycle of Tianjin Green Coal Power. 2,000 tons/day gasification unit for IGCC industrial demonstration project. Compared with the pulverized coal gasification boiler, the chilling process has shorter gasification start-up and stop time, simpler system, longer continuous operation time, lower initial investment, and more moisture in the produced gas, which can be used in the subsequent conversion process. Less or no steam, more suitable for coal chemical projects. Filter Cloth,PE Filter Cloth,PP Filter Cloth Xiahua Envirotech Co., Ltd. , http://www.jsfiltercloth.com
