Introduction to The CFBCBoiler Room Process Water System
Energy-saving Circulating Fluidized Bed Boiler takes the principle of stationary design and circulating fluidized bed map as the guide,the theory of material balance and the theory of particle fuel combusition and a more substantial reduction in the total bed stock,thus form the flow pattern based on the re-structure ofIntroduction to The CFBCBoiler Room Process Water System technology.It represents the latest developments direction of the circulating fluidized bed technology.The structure features ofIntroduction to The CFBCBoiler Room Process Water System are :
1 The structure of a single drum
Introduction to The CFBCBoiler Room Process Water System transverse type
2 The suspension furnace of energy-saving circulating fluidized bed boiler equipped with film water-cooled wall and the imports of separator is water-cooled flue
3 The use of bell hood of
Introduction to The CFBCBoiler Room Process Water System that 's easy to replace,low resistance,non-inverted gray
4 The separator and the center tube of energy-saving circulating fluidized bed boilerhave the technological improvements for low resisitance,high separation efficiency
5 The use of patented technology and equipped with independent device of roots blower to save power consumption
6 The use of low bed pressure operation.
7 The use of lower pressure fans,reducing the power consumption of fans
8 Optimization of secondary air layout and flow vents to reduce the secondary air pressure of fans
9 To improve the fuel crusher and screening system,the coal particalsize is in line with design requirements
10 The air preheater use of a multi-tube boxarrangement,and low-temperature use of corrosion-resistant steel to avoid the corrosion due to low temperature cause to replace the whole.
The performance characteristics ofIntroduction to The CFBCBoiler Room Process Water System are:
1.Power-saving:The fance can reduce more than 30%
Power consumption,operate under low bed pressure,the pressure head of the first,second blower,Roots blower,induced draft fan have been reduced,the power consumption of fans is reduced.
2.Coal-saving:the coal-saving of boiler can reach 3-5%
Operate under low bed pressure,back-pressure reduced in the furnance,reduce the concentration of secondary air regional materials, the effect of secondary air penetration disturbance is enhanced to improve combustion efficiency.
3.Less-wear:There is almost no wear and tear on the heating surface,the annual running time was up to 8000 hours.
4.Operate under low bed pressure,low flow speed of flue gas,small materials concentration in the furnance,less wear and tear,can run for a long period.
