[Ten years of development of chemical equipment] 758-2022 The first set of ultra-high temperature and ultra-high pressure primary reheat dry quenching waste heat boilers in the country

Shanxi Xinshi Energy Technology Co., Ltd.'s 1.8 million tons/year coking supporting 1x250t/h dry quenching coke waste heat power generation system project (referred to as Xinshi waste heat power generation project) is a technology company held by Jianlong Group, Huatai Yongchuang (Beijing) Technology Co., Ltd. Co., Ltd. (Huatai Yongchuang for short) is the general contractor and operator. Jianlongchuan Boiler cooperated with the general contractor to undertake the design and manufacturing of dry quenching coke waste heat boilers, and applied ultra-high temperature and ultra-high pressure primary reheat technical parameters to the field of dry quenching coke waste heat boilers for the first time in China. In view of the generally low power generation efficiency of high and medium pressure dry quenching coke waste heat boilers currently widely used in China, Jianlongchuan Boiler and Huatai Yongchuang broke the rules and adopted a new double super dry quenching coke waste heat boiler solution with reheater for the first time in the Xinshi waste heat power generation project. Compared with conventional boilers, the main steam pressure of the double super dry quenching waste heat boiler can reach 14.2MPa, the temperature can reach 571°C, and the power generation per ton of coke can be increased by more than 12%, which can greatly improve the recovery and utilization rate of coke sensible heat. This is a leapfrog improvement in the efficiency of dry quenching waste heat utilization. Jianlongchuan Boiler, as the country's only national and local joint engineering research center for high-efficiency energy-saving technology for small and medium-sized boilers, has been deeply involved in the research and development of high-efficiency energy-saving technology for small and medium-sized boilers in recent years. In the field of dry quenching coke waste heat boilers, it has cooperated with Huatai Yongchuang to develop and design dual-super-one-time reheat dry quenching coke waste heat boiler technology and water-cooled cyclone separation and dust removal and dry quenching coke waste heat boiler integration technology. The successful operation of Xinshi Waste Heat Power Generation Project is a verification of Jianlongchuan Boiler’s technical strength and service capabilities. In the context of "carbon neutrality and carbon peak", Jianlongchuan Pot will be driven by innovation, adhere to the concept of "quality first, customer first", be committed to promoting the efficient and clean utilization of industrial green energy, and continue to provide customers with high-quality products and services.

Shanxi Xinshi Energy Technology Co., Ltd.'s 1.8 million tons/year coking supporting 1x250t/h dry quenching coke waste heat power generation system project is generally contracted by Huatai Yongchuang (Beijing) Technology Co., Ltd., which includes project design, construction and operation and maintenance. Jianlongchuan Boiler cooperated with the general contractor to undertake the design and manufacturing of dry quenching coke waste heat boilers. It is the first time in China that ultra-high temperature and ultra-high pressure primary reheat technical parameters have been applied to the field of dry quenching coke waste heat boilers.

Although the high- and medium-pressure dry quenching waste heat furnaces currently widely used in China also recover the sensible heat of coke, their power generation efficiency is generally low. Jianlongchuan Boiler and its partner Huatai Yongchuang broke the rules and adopted a new double super-coke dry quenching waste heat boiler solution with reheater for the first time in the Xinshi project. Compared with conventional boilers, the main steam pressure of the double super dry quenching waste heat boiler can reach 14.2MPa, the temperature can reach 571°C, and the power generation per ton of coke can be increased by more than 12%, which can greatly improve the recovery and utilization rate of coke sensible heat. This is a leapfrog improvement in the efficiency of dry quenching waste heat utilization. As the only national and local joint engineering research center for high-efficiency energy-saving technologies for small and medium-sized boilers in the country, Jianlongchuan Boiler has been deeply engaged in the research and development of high-efficiency energy-saving technologies for small and medium-sized boilers in recent years. In the field of dry quenching coke waste heat boilers, it has cooperated with Huatai Yongchuang to develop and design dual-super one-time reheat dry quenching coke waste heat boiler technology and water-cooled cyclone separation and dust removal and dry quenching coke waste heat boiler integration technology. The successful operation of the new stone project is a verification of the technical strength and service capabilities of Jianlongchuan Pot.
