Shuangliang helps the world first low calorific value coal 660MW CFB demonstration unit pass 168 hours of trial operation
On November 27, in Binzhou City, Xianyang City, Shaanxi Province, Unit 1 of the Binchang low calorific value coal 660MW ultra-supercritical CFB demonstration project passed the 168-hour trial run, marking the successful completion of the project construction and its official launch of production operation. The all-steel intercooler project of the project was contracted by Shuangliang Energy Saving EPC. At present, the system is running smoothly and all performance indicators have reached excellent standards.
It is reported that the Shaanxi Binchang project is a "double demonstration" project of science and technology and electricity approved by the Ministry of Science and Technology and the National Energy Administration. It is also the first ecological restoration demonstration benchmark project in the Yellow River Basin in the national coal industry that integrates "comprehensive utilization of solid waste and mine water" and "mine geological environment governance and restoration and land reclamation". The project has "three" world's best and "five" domestic first-class technical characteristics. The construction of this project will effectively consolidate my country's world leading position in the field of CFB power generation technology and further improve the level of clean and efficient comprehensive utilization of coal.
Shuangliang Energy Conservation built the chimney-tower steel structure indirect air cooling system for the project, which integrates the main cooling tower and chimney. The total height of the steel structure tower is 168 meters, and the top outlet diameter (internal skin diameter) is 84 meters. The air-cooled radiator independently developed by Shuangliang is arranged vertically around the outer side of the indirect cooling tower, achieving significant results such as small footprint, low safety risks, and short construction period.
The all-steel intercooler tower project started on April 12, 2023, and the steel tower was topped out on November 22, 2023. The Shuangliang Energy Saving Project Department took 7 months to complete the project nodes as planned with quality and quantity guaranteed. It is the fastest unit for the main construction in the entire field. The mechanical installation was completed on June 15, 2024, and the single unit debugging and point transfer work was completed on June 30, 2024. It is the unit with the fastest operating conditions in the entire field. During the 168-hour trial operation, all performance indicators reached excellent standards, and all parameters met the design specifications. The systems and equipment in the intercooler tower operated smoothly, which was unanimously recognized by leaders and experts of the owner, design institute, supervision and other units.
