Detailed technical parameter table of 130t/h circulating fluidized bed steam boiler

2023-10-12 08:42:38

The 130-ton circulating fluidized bed boiler is a large-scale industrial equipment. The circulating fluidized bed boiler in this article is high temperature and high pressure, with a rated evaporation capacity of 130t/h, a rated steam temperature of 540°C, and a feed water temperature of 215°C. Moreover, the circulating fluidized bed boiler is more efficient than other power station boilers, with a combustion efficiency of about 97% to 99% and a thermal efficiency of over 92%. It is a large-scale energy-saving and high-efficiency boiler type that is promoted in my country.
