Abstract

The utility model discloses a fluid bed furnace. A furnace bin is connected with a coal feeder; the coal feeder is rotationally contacted with a coal blanking pipe; the coal blanking pipe enters a furnace body; a vaporization heated surface is formed in the furnace body; one side of the furnace body is provided with a flue gas outlet; a furnace bed is provided with a grid plate and a cyclone air cap; and the bottom of the furnace bed is provided with a slag discharge pipe. The fluid bed furnace has the advantages that: a high-temperature region needed by combustion is formed by reducing heated surface in a fluid bed region, and heated surface is increased in other regions, so that the heat load requirement of a boiler is met; according to the cyclone air cap, air current is emitted tangentially, eddy current is formed in a bed, transverse mixing and heat mass exchange of a bed material are enhanced, combustion is more complete, and burn-out of low-heat-value coal gangue is facilitated; and coal gangue 4,600 KJ/kg (1,100 Kcal/kg) and oil shale 4,187 KJ/kg (1,000 Kcal/kg) serving as fuels can burn normally after being charged into the furnace, the bed temperature is about 950 DEG C, and the fluid bed furnace can run stably for a long time, and has a good effect and remarkable energy-saving and consumption-reduction effects.

Description

Fluid bed furnace
Technical field
The utility model relates to a kind of combustion apparatus, is a kind of fluid bed furnace specifically.
Background technology
Recirculating fluidized bed is a kind of novel combustion apparatus that grows up nearly decades, and it adopts the fluidized combustion technology to produce steam, high-temperature flue gas, high temperature air.Can be widely used in industries such as generating, papermaking, building materials, chemical industry, smelting.Fluid bed furnace can only burn the colm about 8374KJ/kg (2000Kcal/kg) at present, when the calorific value of coal is lower than 6280 KJ/kg (1500 Kcal/kg), and the stove combustion instability, furnace temperature is on the low side, and thermic load also sharply descends.And when the calorific value of coal low during to 4600 KJ/kg (1100 Kcal/kg), can't fire burns.
The utility model content
To the problem of above-mentioned existence, it is good that the purpose of the utility model provides a kind of combustion efficiency, energy-saving and cost-reducing significant fluid bed furnace.
The technical scheme of the utility model is: fluid bed furnace comprises furnace bin, feeder, coal unloading tube, evaporates heating surface, exhanst gas outlet, air distribution plate, eddy flow blast cap and scum pipe that it is characterized in that: furnace bin links to each other with feeder; Feeder rotates with coal unloading tube and contacts; Coal unloading tube enters in the body of heater, is provided with in the body of heater to evaporate heating surface, and body of heater one side has exhanst gas outlet; Siege is provided with air distribution plate and eddy flow blast cap, has scum pipe at the bottom of the siege.
The advantage of the utility model: through evaporating heating surface is optimized, reduce heating surface, form the needed high-temperature region of burning, and increase heating surface, to satisfy the boiler heat load requirement in other position in fluidised bed zones; The spiral-flow type blast cap penetrates the air-flow tangential, in bed, forms eddy current, makes horizontal mixing of bed material and caloic exchange better, and it is more abundant to burn, and helps the after-flame of low calorific value coal spoil; When fuel is gangue 4600 KJ/kg (1100 Kcal/kg), when oil shale was 4187 KJ/kg (1000 Kcal/kg), going into behind the stove all can normal combustion, and bed temperature reaches about 950 ℃, can operation steady in a long-term, and respond well, significantly energy-saving and cost-reducing.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the structure cutaway view of eddy flow blast cap.
Fig. 3 is A among Fig. 2-A face structure cutaway view.
The specific embodiment
Combine accompanying drawing at present, the utility model is further specified.
As shown in Figure 1, furnace bin 1 links to each other with feeder 2, and feeder 2 rotates with coal unloading tube 3 and contacts; Coal unloading tube 3 enters in the body of heater, is provided with in the body of heater to evaporate heating surface 4, and body of heater one side has exhanst gas outlet 5; Siege is provided with air distribution plate 6 and eddy flow blast cap 7, has scum pipe 8 at the bottom of the siege.
