4 sets of ZOZEN 70MW gas-fired hot water boilers promote the central heating business in Xiqing District in Tianjin

31 Dec 2020

Recently, the coal-to-gas project between ZOZEN Boiler and Tianjin Ruicheng Thermal Power Co., Ltd. including 4 sets of 70MW gas-fired boilers had been successfully put into use. In order to make the residents have a warm winter, ZOZEN spared no efforts to complete the boiler production in time and provide technical guidance for the boiler installation and commissioning to help Ruicheng Thermal Power complete the coal-to-gas task.

ZOZEN signed the contract with Ruicheng Thermal Power who purchased 4 sets of 70MW gas-fired boilers

This year, as a large-scale heating company in Xiqing District, Ruicheng Thermal Power invested 99 million yuan to replace the existing coal-fired boiler system with 4 sets of new 70MW gas-fired hot water boilers with the total capacity unchanged. It also planned to complete the commissioning and operation of the whole heating system before the heating period of 2021 to ensure the heating service for the residents.

In view of the high requirements for the large-tonnage heating system, ZOZEN recommended the SZS series gas-fired hot water boiler for Ruicheng Thermal Power. The boiler has reasonable structure, reliable and safe operation, and wide capacity range of 7-116MW, which can meet the demands of central heating. In addition, the boiler also adopts the large-volume furnace and imported ultra low-NOx burner which can reduce the generation of NOx and reach the emission standard of less than 30mg/Nm3. There also are waste heat recovery devices at the boiler tail such as the condenser and economizer to improve the boiler thermal efficiency to over 95% and reduce the operating costs.

As a large-scale boiler manufacturer in China, ZOZEN has the industry-leading CNC production lines to realize the professional and large-scale production of main boiler parts, so as to meet the short-time delivery demands. Making the production tasks clear, ZOZEN adjusted the production schedule and completed the delivery in 45 days, which saved sufficient time for the boiler installation and commissioning.
