New Type Double Spiral Low Speed Circulating Fluidized Bed Steam Boiler

Introduction :

New Type Double spiral low speed circulating fluidized bed steam boiler which belongs to the Zhengzhou circulating fluidized bed boiler, Tsinghua university research, which is the latest scientific research achievements of Tsinghua University adapted. This type of boiler inherit the original technical advantages, at the same time,it achieved the scientific breakthrough in the technology of vortex fluidized combustion ,Wind vortex separation structure design and parameterized design，the separation vortex wind structure design and parametric design technology, returning technology, is the national patented product.

Advantage:

1、It adopts the membrane water wall to arrange the furnace,separator,revert system into one whole part,the structure is compact.

2、It has achieved major technical breakthrough in structure and parameterization of separator,effectively improve the burning and separator efficiency.

3、Return feeding of revert system is constituted by 2 pieces of membrane water wall,parts of heat energy carried by flying ash can absorbed by water wall,and besides it uses the device of style type boiling fluidization inheritance return feeding and realize the fluidized state of return fuel.

4、The anti-erosion design uses many measures,wide coal adaptability,and vortex fluidized combustion technology realize the material burning in swirl fluidized combustion cycles inside of combustion chamber,thus improving the burning efficiency.Besides,it reduce the fault rate and can run continuously for long time.

5、It adopts low temperature combustion technology,can effectively reduce the harmful gas,and realize the desulfuration inside of furnace,accord with national policy of energy saving and environmentally friendly.
