Circulating Fluid Bed Boiler  #SteamBoiler #HotWaterBoiler

Circulating fluidized bed combustion technology, is kind of new and mature coal combustion clean technology, with high-efficiency, low-pollution. 

With characteristic of low-temperature combustion, the NOx emissions are much lower than that of normal pulverized coal furnaces. CFB Boiler has NOx emission only about 100mg/Nm3, and can achieve direct desulfurization during the combustion process, with high desulfurization efficiency. The technical equipment is economical and simple, and its initial investment and operating costs for desulfurization are much lower than that of dry pulverized coal furnace plus flue gas desulfurization (PC+FCD).

 SHX & DHX Series Boiler  

SHX series circulating fluidized bed boiler, double drum horizontal type boiler.

DHX series circulating fluidized bed boiler, single drum horizontal type boiler.

1. It has wide fuel adaptability and high combustion efficiency, especially suitable for low calorific value and low-quality COAL/BIOMASS, Sludge, Solid Waste.

2. The discharged ash has good activity and is easy to be comprehensively utilized without secondary ash pollution.

3. The load adjustment range is large, and the low load can be reduced to about 30% of the full load.

 Advantages  CFB Coal Boiler 

Low coal consumption: high-efficiency separation + circulating combustion, combustion efficiency >99% or more, thermal efficiency >92%, coal consumption reduced by more than 3%

Save electricity bills: Restructure the flow pattern to achieve low bed pressure operation. The low power consumption rate of the factory can save more than 20% of the fan power consumption.

Environmental protection and low emissions: precise low-temperature staged combustion and air distribution, ultra-low initial emissions of SO2 and NOx, and superior environmental performance

Low wear: low bed pressure operation, low flue gas flow rate, nearly zero wear on the heating surface, low maintenance rate, annual operating time >8000 hours

Good fluidization: Patented improved bell-type wind cap solves the problems of ash pouring and fluidization to ensure boiler combustion efficiency and low emissions

High separation: The optimized center-offset high-efficiency cyclone separator is used to ensure efficient separation, with an efficiency of over 99.6
