The Coal Chemical Engineering Expert Committee of Jinmei Group held an expert seminar on the Jinhang Furnace project. Author/Source: Modern Coal Chemical Engineering. Date: May 5, 2020. Clicks: 65. On April 28, 2020, the Coal Chemical Engineering Department and the Coal Chemical Engineering Research Institute of Jinmei Group organized seven experts from the committee to visit the Wenxi branch of Jinfeng Company, in order to discuss and evaluate the 168-hour operation of the Jinhang Furnace project. In recent years, with the maturity and widespread adoption of new powder coal gasification technologies, along with **industry policy restrictions**, the traditional fixed-bed batch gasification process (UGI) has been phased out at an accelerated pace, resulting in an unprecedented crisis of oversupply for anthracite coal in our province. Smokeless lump coal is primarily consumed through coal chemical processes. The development of new technologies for pressurized gasification of lump coal will help restore its competitive advantages as a product, support the implementation of the \"three modernizations and one transformation\" strategy in the chemical industry, and provide strong backing for the transformation and upgrading of the traditional coal chemical industry in our province and across the country. On April 27, 2020, the Jinhua Coal Furnace (Jinmei H Furnace) successfully completed its 168-hour industrial test, paving a new exemplary path to overcoming the challenges associated with the clean and efficient use of anthracite coal in our province, as well as to facilitating the low-cost, high-quality transformation of traditional coal chemical enterprises. The process technology of the Jinhang furnace (Jinmei H furnace) has the following advantages: First, it uses crushed coal (6–50 mm) as raw material, resulting in simple raw material processing. Secondly, by drawing on the precise control techniques from the aerospace industry, modifying the slag discharge structure, and adding a small amount of solubilizers, it is possible to achieve liquid slag discharge for bituminous coal with a high ash fusion point. Thirdly, it features a high gasification temperature, a high content of useful gases (with methane levels as low as less than 1.5%), a high carbon conversion rate (greater than 99%), and low residual carbon in the ash. Fourth, it is more environmentally friendly: the emissions of waste gases, wastewater, and solid waste meet **standards**, and the steam consumption is only 1/6 that of Lurgi furnaces. Fifth, it features a high degree of automation and intrinsic safety. Through program design and precise sequential control, “one-button” ignition is achieved without any on-site operation. Sixthly, the cost is low; the comprehensive cost per ton of ammonia is significantly lower (by more than 18%) compared to traditional fixed-bed batch gas generation furnaces. Additionally, a \"modular\" construction approach is adopted for the core gasification components, which reduces the construction time and lowers costs. The expert group visited the central control room of the Jinfeng Wenxi branch and the site of the \"Jinhang Furnace\" in sequence, to gain a detailed understanding of its operation status, equipment process parameters, and construction projects; they also inspected the actual structure of the \"Jinhang Furnace\" as well as the slag discharge process. After listening to the summary reports presented by companies such as Wenxi Company, Aerospace Power Company, and the Coal Chemical Engineering Research Institute regarding the technology involved in the Jinhang Furnace project as well as its performance during 168 hours of operation, the experts present, through thorough discussion, agreed that this technology successfully overcame the challenge of liquid slag discharge with high-ash-melting-point anthracite, enabling continuous and stable operation. The various process parameters were excellent, and the technology was advanced, safe, and reliable. The expert group requested the project team to carefully summarize the operation status of the Jinhang furnace, organize the subsequent work properly, conduct more accurate economic analyses, and lay a foundation for the industrial application and promotion of the Jinhang furnace.
