Optimizing urban heating in Taiyuan and Jinzhong for low-carbon development

achevé

In Taiyuan, the project involved phasing out 254 inefficient small boiler systems 20 years and building three levels of urban heating networks: a 9.6 km-long primary network from the power plant to a pressure isolation station, a 44 km-long secondary network comprising 75 substations, and part of the tertiary network. This network is supplied by a cogeneration plant and supplies a surface area of 10.6 million square meters.In Jinzhong, 677 small boiler systems and 8 district boiler systems with low levels of efficiency were decommissioned. They were replaced by a heating network for which the first 97.5 km-long phase is equipped with 87 heat exchange stations and supplied by a new cogeneration plant. This network supplies a surface area of 10.15 million square meters.
