Detailed description of the invention

By reference to the accompanying drawings, detailed description of the invention of the present utility model is described further:

As Fig. 1, utilization shown in 2 two-stage of burning fin type water pipe furnace grate that is all-trans adjusts wind furnace thorax, comprise the base 1 of body of heater 13 and support body of heater 13, described body of heater 13 inside is provided with anti-burning fin type water pipe furnace grate 7 and gear cigarette return facilities 3, gear cigarette return facilities 3 is located at anti-below of burning fin type water pipe furnace grate 7, be feed compartment 8 above anti-burning fin type water pipe furnace grate 7, cavity between anti-burning fin type water pipe furnace grate 7 and gear cigarette return facilities 3 is combustion chamber 5, it is heat absorption district 19 below gear cigarette return facilities 3, heat absorption is provided with some endothermic tubes 18 in district 19, the bottom of combustion chamber 5 is provided with the combustion chamber crater 2 through with district 19 of absorbing heat.

Body of heater 13 sidewall of described feed compartment 8 correspondence is provided with deashing and inspection socket 9, charge door 10 and some primary air regulators 12, be provided with the fire door 11 being convenient to opening and closing in charge door 10, body of heater 13 sidewall of described combustion chamber 5 correspondence is provided with shoot door 4 and some secondary air registers 6.Utilize deashing and inspection socket, shoot door can clear up dust in feed compartment and combustion chamber in time, be conducive to the Thorough combustion of fuel, play the effect that flue gas diffuses simultaneously in blowing out or when banking up a fire.Primary air regulator and secondary air register are distributed on the front, rear, left and right sidewall of body of heater, arrange multiple primary air regulator, considerably increase the contact area of oxygen and fuel, make oxygen supply fully realize clean combustion; Utilize secondary air register to regulate to make after primary combustion, containing the flue gas of certain proportion CO after-flame completely again in combustion chamber, to discharge pure qi (oxygen), realize the clean combustion of boiler to air quantity.

All control valve is installed in each primary air regulator and secondary air register, suitable air register can be selected according to actual needs to open quantity and position.

The bottom of described body of heater 13 is also provided with water seal and falls ashpit 20, the bottom surface of body of heater 13 has ash port 21, and the water seal ashpit 20 that falls is through by ash port 21 and combustion chamber 5, and described ash port 21 place is provided with hinge-type water seal board 22.Most of dust in flue gas to be fallen ashpit 20 sedimentation pump drainage by water seal, and hinge-type water seal board 22 only just can be opened in the operation of dust gravity, prevents flue gas from directly entering water seal through ash port 21 and falls in ashpit 20.

Body of heater 13 sidewall bottom of described heat absorption district 19 correspondence is provided with dedust port 17, water return outlet 24 and sewage draining exit 25, can clear up the dust, ponding etc. of bottom of furnace body in real time.

The top of described body of heater 13 is provided with water tank 16, and each endothermic tube 18 is connected with water tank 16.Water circulates between endothermic tube 18 and water tank 16, cyclic process is lowered the temperature to flue gas, in water tank 16, a water-level gauge also can be set, to observe the water level in water tank, body of heater can be opened in the through delivery port of water tank and air connector, facilitate pump drainage or make-up water, prevent from being unfavorable for observing the state in water tank because water temperature raises generation fog simultaneously.

As Fig. 4, shown in 5, described anti-burning fin type water pipe furnace grate 7 by some extended surface tubes side by side gap weldig form, welded gaps between adjacent fin pipe forms ventilation section 73, extended surface tube comprises water cooling tube 72 and horizontal symmetrical and is welded in some fins 71 on water cooling tube 72 outer wall, described fin 71 is arranged along water cooling tube 72 axis direction spaced set two, each fin 71 is in same plane with the axis of water cooling tube 72, the solder side of described fin 71 is crescent, the side relative with solder side is the fin head of rounding, the thickness of fin is 8-10mm, be highly 40mm, fin head is 30-35mm to the distance of the center of welding (beeline namely between fin head and water cooling tube), the width of ventilation section is 20-25mm, and this width distance effectively can increase ventilation, is conducive to the Thorough combustion of fuel.Therefore on the basis of same grate area, greatly increase the sectional area that fires of fire grate, the resistance that flue gas moves downward reduces, and increased flame speeds, improves burning velocity and ignition temperature.The structure of fin is crescent, compared with the rectangular fin of tradition, one adds and the contact area of water cooling tube and weld strength, it two is convenient to deashing and disclose fire, it three adds ventilation more, its four service life extending fire grate, its five, unburnt fuel can be stoped to leave out by mistake by the structure interval rationally between effective crescent fin and waste energy.

Fin and water cooling tube are vertical Welding Structure, along its axis direction welding two row fin on every root water cooling tube, two row's fins are symmetrical and be in same plane with the axis of water cooling tube, 30mm is set to along adjacent two fins of water cooling tube axis direction, such design had both been conducive to contact area when welding with water cooling tube, increase weld strength, be conducive to again deashing simultaneously and increase ventilation.

Described anti-burning fin type water pipe furnace grate 7 is obliquely installed along water cooling tube 72 axis direction, and angle of inclination is determined according to the degree of depth of burner hearth and water circulation direction.

Described gear cigarette return facilities 3 is obliquely installed along its axis, the one end be connected with burner hearth backhaul plate 27 end is high-end, combustion chamber crater 2 is located at the low side of gear cigarette return facilities 3, make the dust after burning fall to vertically dropping down onto ash port 21 through combustion chamber crater 2 again along the gear flue and water pipe tilted, finally enter the water seal ashpit 20 that falls and carry out precipitation pump drainage.Gear cigarette return facilities 3 can adopt two kinds of structures, a kind of for shown in Fig. 2, is be welded side by side by some gear flue and water pipes; A kind of for shown in Fig. 3, adopt box backhaul water jacket.Gear flue and water pipe can be connected by water tank with backhaul water jacket, forms recirculated water.

The specific works process of this boiler is:

Fuel enters on the anti-burning fin type water pipe furnace grate 7 of feed compartment 8 by charge door 10, under the effect of extraneous air inducing and primary air regulator 12, flue gas after burning enters combustion chamber 5 through after red-hot coke layer, in flue gas, unburnt CO is by the combustion-supporting complete after-flame of secondary air register 6, the flue gas in afterburnt is by combustion chamber crater 2 being advanced into heat absorption district 19, heat exchange is carried out with the endothermic tube 18 in heat absorption district 19, flue gas after cooling is expelled in outside wet type dedusting devulcanizer through outlet flue, and dust is through combustion chamber crater 2, ash port 21 drains into water seal and falls in ashpit 20, realize the environmental protection and energy saving operational effect of smokeless and dust free.What the direction of arrow shown in Fig. 1 was flue gas flows to index line.

When blowing out or when banking up a fire, open the adjustable plate 15 put on ash and flue gas diffusion mouth 14, and close the valve of primary air regulator 12, open the secondary air register 6 of combustion chamber, allow residual air discharge and realize safe operation.

Boiler described in the utility model can be adapted to heating furnace, heating stove, steam oven and various combustion apparatus etc.; Fuel can be coal, coke, biomass fuel, moulded coal etc.; Manufacture material and can be steel and foundry goods etc.Medium can be water, conduction oil, air etc.
