Comply with the Work Safety Law! Take on the role of the primary responsible person! ---------------------------------------------- The past decade has been a period of rapid development in China’s chemical industry, marked by the emergence of many new processes, products, and equipment. China’s chemical processing equipment has also seen significant progress, which has contributed to the swift advancement of the petrochemical sector. Here, we have compiled some of the achievements and breakthroughs made by Chinese equipment manufacturers in terms of larger-scale production and increased use of domestic equipment. We invite everyone to share their insights and discuss these topics together; let’s cheer for Made in China and support the development of chemical processing equipment! ------------------------------------------------------ The multi-nozzle opposed semi-waste-boiler gasifier, which is the core equipment of the industrial demonstration plant for the water-coal slurry gasification technology using a multi-nozzle opposed waste-boiler cooling process in Yulin Energy Chemical Industry, was manufactured by Xinhai Equipment and represents the first of its kind in the world. The equipment is 45.75 meters long, has an inner diameter of 4.2 meters, weighs 737 tons, and can process 2,000 tons of coal per day. It features a high carbon conversion rate, high overall thermal efficiency, and high efficiency across the entire system. The successful development of this equipment represents a milestone in the advancement of coal gasification technology in China.
From May 27 to 29, 2022, the China Petroleum and Chemical Industry Federation organized experts to go to Yulin Energy Chemical to conduct a 72-hour continuous operation test on the **key research and development project titled “Industrial demonstration unit for water-coal slurry gasification technology using a multi-nozzle opposed-type waste boiler–quenching process capable of processing 2,000 tons of coal per day per furnace.” The gasifier achieved successful operation on its first feed on December 10, 2020, and has now accumulated 6,334 hours of operation. Following the evaluation, the expert panel unanimously agreed that the demonstration unit operated smoothly during the 72-hour testing period, provided accurate measurement and analysis, and its various technical parameters exceeded the specified requirements. Among them, the steam yield generated as a by-product of the radiation waste boiler is 799 kg/1000 m3 (CO+H2), and the efficiency of the hot gas is 84%. The device features a high degree of automation, flexible operation control, and safe and reliable performance. It also has advantages such as a high carbon conversion rate, low raw material consumption, and advanced process parameters. The by-produced high-pressure saturated steam can be used for power generation, reducing the investment required for constructing utility boilers and in line with **energy conservation and emission reduction policies. The expert group unanimously determined that the assessment was successfully passed. The multi-nozzle opposed waste boiler-cooling process water-coal slurry gasifier was jointly developed by the former Yankuang Group and East China University of Science and Technology. The gasifier shell has an inner diameter of φ3.6/4.2 meters, with a total height of 45.75 meters. The gasification chamber is constructed of refractory bricks and is about 8 meters high. The radiation waste boiler section features a membrane-type water wall structure and is approximately 25 meters high. The quenching section is about 6 meters high. The daily coal processing capacity is 2,000 tons. Most of the sensible heat in the high-temperature syngas is recovered by the waste heat boiler in the gasifier, producing approximately 100 tons of high-pressure steam at 9.8 MPa per hour as a by-product. This is an industrial demonstration plant for the multi-nozzle opposed water-coal slurry gasification waste boiler–quenching process.
The multi-nozzle opposed semi-waste-boiler gasifier, which is the core equipment of the industrial demonstration plant for the water-coal slurry gasification technology using a multi-nozzle opposed waste-boiler cooling process in Yulin Energy Chemical Industry, was manufactured by Xinhai Equipment and represents the first of its kind in the world. The equipment is 45.75 meters long, has an inner diameter of 4.2 meters, weighs 737 tons, and can process 2,000 tons of coal per day. It features a high carbon conversion rate, high overall thermal efficiency, and high efficiency across the entire system. The successful development of this equipment represents a milestone in the advancement of coal gasification technology in China.
