Recently, the People’s Government of Shanxi Province issued the “Decision on the 2022 Shanxi Province Science and Technology Awards”; the project “Research, Development, and Industrialization of a Water-Cooled Wall Directly Connected Waste Boiler Gasification Furnace for Coal Water Slurry” (Jinhua Furnace 3.0) received the first prize in the 2022 Shanxi Province Science and Technology Progress Award. Focusing on the key technologies and equipment for the recovery of sensible heat in large-scale gasification, this project conducted research on the heat recovery mechanism of gasifiers with water-cooled walls connected directly to waste boilers, as well as on the hydrodynamics of heat recovery systems. It innovatively designed a structure for direct connection to radiation waste boilers, developed key manufacturing techniques for such gasifiers, and based on engineering demonstrations, successfully created gasifiers with water-cooled walls connected directly to waste boilers that are at the international leading level. This achievement marked the first time that efficient recovery of sensible heat from syngas produced in large-scale gasification was realized on an industrial scale. The main innovation of the project lies in elucidating the flow and heat transfer mechanisms of the three phases—gas, liquid slag, and fly ash particles—in the radioactive waste reactor ； A hydrodynamic flow and heat transfer model for membrane-type water wall was established ； A integrated structure that directly connects the water wall gasification chamber with the radiant waste boiler was designed and developed, along with key manufacturing technologies such as the automated welding process for high-alloy steel circular tubes and radially double-faced cladding walls, the electroslag wire electrode surfacing process for corrosion-resistant linings, as well as laser-based measurement and alignment techniques. A total of 68 patents have been granted for this project, including 5 invention patents and 63 utility model patents. Compared with similar technologies at home and abroad, it overcomes the critical problem that prevents long-term stable operation of gasifiers directly connected to radiation waste boilers due to ash accumulation and slag blockage. It boasts significant advantages such as wide adaptability to different coal types, high heat recovery efficiency, low project investment, low operating costs, long periods of safe and stable operation, and environmental friendliness along with the ability to handle hazardous waste in a coordinated manner. Key technical performance indicators: specific oxygen consumption of 374.2 Nm3O₂/kNm3(CO+H₂), specific coal consumption of 581.8 kg of coal/kNm3(CO+H₂); effective content of syngas (CO+H₂) at 80.72%; thermal efficiency of 98.4%; steam generated as a by-product in the radiant waste boiler at 810.0 kg/kNm3(CO+H₂); carbon conversion rate of 97.61%; pressure range of 6.5–8.75 MPa; continuous operation time of 150 days; maximum coal feeding rate of 3,000 tons per day. It can meet the requirements of large-scale coal gasification projects such as those for coal-to-methanol, coal-to-gas, coal-to-olefins, coal-to-ethylene glycol, and coal-to-oil production on a million-ton scale. This technology has been included in the **National Development and Reform Commission’s ‘Guidelines for Energy Conservation and Carbon Reduction Transformations in Key Sectors of High-Energy-Consuming Industries (2022 Edition)’ and ‘Guidelines for Energy Conservation and Carbon Reduction Transformations in the Ammonia Synthesis Industry (2022 Edition)’, as well as the Ministry of Industry and Information Technology’s ‘Guidelines and Cases for the Application of Industrial Energy-Saving Technologies (2019)’ and ‘List of Green and Low-Carbon Processes in the Petrochemical Sector (2021 Edition)’. The product was selected as a single-champion product in the manufacturing sector for 2021 by the Ministry of Industry and Information Technology. As of the end of April 2022, 37 units of this product had been sold and 32 units had been ordered; sales revenue amounted to 3.24 billion yuan, while additional profits reached 907 million yuan. Of these, 12 units have been put into operation, generating social benefits worth 1.9 billion yuan, reducing CO₂ emissions by 8.56 million tons, and improving the energy efficiency of the coal chemical industry. This has provided a \"Shanxi solution\" for the high-quality transformation and development of Shanxi as well as for achieving the national \"dual carbon\" goals. It is reported that for the First Prize for Scientific and Technological Progress in Shanxi Province, in accordance with the application and evaluation procedures and requirements, the project went through five rounds of evaluation: a formal review, an online review, a plenary session evaluation, a sub-group evaluation, and an on-site review
