Description

A kind of new-type fluidized bed smoke furnace

Technical field

The utility model relates to fluidized bed smoke furnace technical field, specifically a kind of new-type fluidized bed smoke furnace.

Background technique

Fluidized bed smoke furnace is a kind of type of furnace for burning particles fuel, and traditional fluidized bed smoke furnace is called boiling Furnace is made of furnace body and fluidisation air-distribution device, and granular fuel is furnace bed by gravity feeding boiling by fuel feedstock mouth, combustion-supporting Wind is sent into siege by bellows, makes fuel suspension combustion on siege by fluidizing air distribution plate, the slag for burning completion is straight by scum pipe Run in outside furnace, by manually being stored up with cart transport.

With industrialized process, the requirement to industrial equipment is gradually increased, and conventional fluidization pool furnace type deposits following ask Topic:

1, furnace body enlargement is difficult, and the former fluidized bed type of furnace is mostly to be less than the 14MW type of furnace, can be expired using traditional stalk structure Sufficient requirement, because of the raising of furnace wall height, improves the swell increment of furnace wall, is not increasing furnace during furnace body enlargement Increase height under the premise of wall thickness, the maintenance cycle of converter life sharp fall, furnace wall shortens.

2, fuel tolerance is poor, the type of granular fuel be it is diversified, from low to high according to fugitive constituent, fuel combustion Ignition temperature when burning is that from high to low, conventional types of furnaces does not have good modulability, to operator on fuel tolerance Stoker's skill requirement of member is higher, and the fault-tolerance and tolerance in combustion process are all lower.

3, furnace combustion intensity is low, and in combustion, combustion space space utilization is insufficient, and fluid bed furnace is in work for conventional types of furnaces The emulsion zone of lower end and the dilute-phase zone of upper end can be divided into when making in burner hearth, the emulsion zone of conventional types of furnaces is shorter, local high temperature zone without Method, which is adjusted, causes furnace wall to hang coke, lengthens emulsion zone and is conducive to improve combustion intensity, but there are emulsion zone feeds for conventional types of furnaces Difficult problem: the mode of emulsion zone feed is to install the screw conveyor companion for passing through furnace wall using the emulsion zone of burner hearth at present With there is cooling wind, by screw conveyor into the emulsion zone of burner hearth forced feeding, fuel enter burner hearth after, immediately with concentrated phase A large amount of fluidized pellet fuels in area are mutually collided, are rubbed, dusting, burning increase substantially the burnout rate of fuel, but stop When furnace, system can also shut down fluidisation cooling wind, and screw conveyor stops feed, and spiral fuel can not be emptied all, lead to spiral shell It revolves discharge gate and continues smoulder, make equipment damage or blocking, booting next time continues normally be fed when production, needs to carry out Cooling cleaning, labor intensity is big, influences production efficiency.

4, UTILIZATION OF VESIDUAL HEAT IN is difficult, and in industrial production system, entire operation area is all no longer independent operating, other systems it is remaining Hot waste gas is recycled according to specific characteristic is recyclable, but because the structure of conventional types of furnaces limits, close phase combustion zone and dilute phase are fired Burn area not separated, usually can only only recycle waste heat exhaust gas by exhanst gas outlet, the utilization rate of waste heat compared with It is low.

5, the main labor intensity of large labor intensity, conventional fluidization bed combustion gas furnace is deslagging and stoker, because fluidized bed is arranged Waste residue temperature out is higher, and generally at 300 ~ 600 degree, for bed drain purge of Large Furnace up to 0.1 ~ 0.2t, slag-drip opening periphery is also adjoint Dust and radiant heat, environment is poor, and the waste heat of waste residue is not collected recycling.
