Project Description

HRSG Ultra-long Boiler Tubes

Product Description

In combined cycle power plants, HRSG (Heat Recovery Steam Generator) boilers recover waste heat from gas turbine exhaust gases to generate steam that drives a turbine for electricity generation. HRSG ultra-long tubes are essential components of these boilers. At present, Changbao has developed a series of HRSG ultra-long tubes with multiple specifications, which have been certified by renowned domestic and international customers such as Harbin Boiler Works, Shanghai Boiler Works, Dongfang Boiler Works, IHI, ALSTOM, etc., and the products are exported to overseas markets like Japan, South Korea, and the United States.
