SHX coal-fired CFB (circulating fluidized bed) stea

Zozen Boiler-SHX coal-fired CFB (circulating fluidized bed) steam boiler. Working pressure: 1.25-2.45MPA: Circulating fluidized bed combustion is low-temperature combustion, so the NOx emission is much lower than that of pulverized coal furnace, only 200ppm. CFBC can desulfurize directly during the combustion process, and the
