China Drying Network News Guizhou Xinyu Coal Chemical Company's coal gasification project originally used multi-component slurry gasification technology, annual processing of 300,000 tons of methanol, put into production in December 2010. Due to the problem of the compatibility between the multi-component slurry gasifier and the coal, the raw coal for this project has been using coal produced in Yunnan, and the transportation cost is very high.
"Guizhou itself produces abundant coal but uses coal from other people. Guizhou Guizhou coal chemical industry industry invited experts from all aspects of production, research, and research in the country to discuss the transformation of a multi-component slurry gasifier into a coal-water slurry water-wall gasifier project. Feasibility plan, hope to achieve localization of raw coal through transformation.†Ni Defei, deputy chairman and general manager of Guizhou Shuicheng Mining Group, told reporters. It is understood that the coal ash melting point of the Shuicheng Mining Group is around 1450°C, and the multi-component slurry gasifier is not suitable for coals with such a high ash melting point, while the coal ash melting point for the coal-water slurry water wall gasifier is 1500 Above °C, local coal can be used for high temperature continuous production.
According to reports, Beijing Yingde Qingda Technology Co., Ltd., Donghua Engineering & Technology Co., Ltd., and Guizhou Xinyu Coal Chemicals Co., Ltd., etc., signed a letter of intent for cooperation at Donghua Engineering & Technology Co., Ltd. at the end of July. The parties plan to relocate the multi-material slurry gasifier of Guizhou Xinyu Coal Chemical Company into a water coal slurry water-wall gasifier project within six months to complete the first transformation of the world's new coal gasifier, thereby confirming China's new gas in the world The leading position in the transformation of the furnace.
The seven parties involved in the transformation project reached an agreement: Beijing Yingde Qingda Technology Co., Ltd. is responsible for process technical support, providing water coal slurry water cooling wall technology package and responsible for opening and stabilizing the system to achieve the desired goals; Donghua Engineering & Technology Co., Ltd. is responsible for The preliminary design, detailed engineering design and on-site project management of the project; Harbin Boiler Works is responsible for the transformation of the equipment body, responsible for the cutting, grinding, welding, lifting and installation of the multi-material slurry gasifier; Shanxi Yangmei Fengxi Chemical Equipment Co., Ltd. Responsible for the production of water-coal slurry waterwall gasifier internals; Beijing Aerospace Petrochemical Technology and Equipment Engineering Company is responsible for the provision of new burners; Luoyang Haite Refractory Materials Co., Ltd. is responsible for the provision of localized new refractories; Guizhou Xinyu Coal Chemical Company cooperates All parties on-site construction are responsible for training personnel and setting up a good system.
