The second phase of the Langfang cogeneration power plant in Hebei Province, operated by Guodian Power (國電電力), a subsidiary of China Energy Investment Corporation (國家能源集團), has reportedly entered full-capacity commercial operation. Unit 4 reportedly passed a 168-hour full-load trial run on the night of August 12 and entered formal commercial operation, completing the 2×350MW (megawatt) equal-capacity replacement project.
The Langfang cogeneration plant Phase 2 project replaces aging equipment with two 350MW-class coal-fired cogeneration units, reportedly carried out as a demonstration project for ‘new high-efficiency flexible coal-fired power generation technology’ under the Huairou (懷柔) National Laboratory. Unit 4 reportedly applies several core technologies for the first time, including flue-gas molten salt heat storage integration, a new ultra-low-load stable combustion burner, and multi-variable intake coordination between the steam turbine and molten salt system. However, the original report did not disclose the specific equipment suppliers or technology licensors for these systems, so this information could not be confirmed.
