Abstract
The utility model discloses a coal firing hot-blast stove. The front of the stove body is provided with a coal gate and a coal scuttle; an air room and a chain grate are arranged below the stove body; a hearth is internally provided with a front stove arch and a back stove arch; the upper part of the stove body is provided with a hot wind outlet. The utility model is characterized in that the inclined back stove arch has an included angle between 5-15 degrees with the level, and the upper part of the hearth is provided with an upper stove arch. The utility model can greatly improve the ignition condition and can be suitable for the normal combustion of a plurality of coal types. All combustible matters can be fully combusted in the utility model, thereby realizing the improvement of combustion efficiency and reaching the purposes of saving energy and reducing environmental pollution.
Description
Technical field
The utility model relates to a kind of air heater with heat-generating device, specifically a kind of coal-fired hot-blast stove.
Background technology
CN1216814 discloses a kind of coal-fired hot-blast stove, and its structure is to be provided with coal flashboard, coal bunker in body of heater the place ahead, and air compartment and traveling-grate stoker are set below body of heater, is provided with preceding chimney arch, back chimney arch in burner hearth, has hot-blast outlet in upper of furnace body.During work, the traveling-grate stoker of rotation advances the ribbing in the coal bunker in the burner hearth, and along with constantly in the past motion backward of fire grate, the preheating destructive distillation is forwardly passed through in the coal seam in moving, in the portion fire burns, become ash to the rear portion after-flame.The hot-blast stove of this structure, the air port that forms between preceding chimney arch and the back chimney arch is when having strong exhausting ability, the defective of bringing be exactly the combustible that in chain fire-gate front portion is in the preheating dry distillation area, discharges can by fast since then the air port aspirate away, make this part combustible under the state of incomplete combustion, be drawn into flue, so just cause burning insufficient, the problem that the thermal efficiency is low.
The utility model content
The purpose of this utility model will provide a kind of sufficient combustion exactly, the tangible coal-fired hot-blast stove of energy savings.
The utility model is achieved in that in body of heater the place ahead and is provided with coal flashboard, coal bunker, air compartment and traveling-grate stoker are set below body of heater, in burner hearth, be provided with preceding chimney arch, back chimney arch, have hot-blast outlet in upper of furnace body, the back chimney arch that tilts and the angle of horizontal plane between 5-15 °, chimney arch on upper furnace is provided with.
Preceding chimney arch below in the utility model constitutes the preheating dry distillation area, and back chimney arch below constitutes the combustion zone that catches fire.The angle of inclination of back chimney arch and horizontal plane is between 5-15 °, promptly the back chimney arch is nearer with coal-fired distance, therefore, its easier and a large amount of exchange heat and transmission of coal seam realization, simultaneously also give off a large amount of heats to the combustion zone that catches fire of burner hearth, will make the coal seam of chimney arch below, back more inflammable like this, the flame of combustion zone, flue-gas temperature is also higher, like this, can make coal adaptive surface of the present utility model wider first, second since chimney arch below, back the flue-gas temperature that fire burns produced higher, so the combustible that discharges in the preheating dry distillation area also can reach ignition temperature with after it mixes, thereby make the combustible in the dry distillation area also can in burner hearth, fully burn, and then the raising efficiency of combustion, reach energy savings, reduce the purpose of environmental pollution.
The back chimney arch of this low length, not only and formed low and long ignition zone between the fire grate, ignition condition is improved greatly, and, make to have formed pre-small post-large flue gas pressures buffering area between back chimney arch and the last chimney arch that in this buffering area, the solid particle material in the flue gas relies on self gravitation to descend, be sunken to the back chimney arch above, thereby reduced the content of the graininess pollutant of sending in the hot blast.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
This coal-fired hot-blast stove is to be provided with coal flashboard 14, coal bunker 1 in body of heater the place ahead, air compartment 5 is set below body of heater and establishes by tuned plate and regulates air door 4 into the air quantity size, and uncovered above the air compartment, the wall sealing has the leakage apparatus for ash below.The top of air compartment is the upper strata of traveling-grate stoker 7, and the below of air compartment is chain fire-gate lower floor, and the wheel shaft of the preceding sprocket wheel 2 of traveling-grate stoker 7 is driven through arrangements for speed regulation by motor.The grey mechanism 13 of retaining is set at the rear of traveling-grate stoker rearward end, and the below that keeps off grey mechanism is provided with mucking machine 6, is used for lime-ash is exported body of heater.Have hot-blast outlet 8 in upper of furnace body, chimney arch 3, back chimney arch 10 before in burner hearth, being provided with, the back chimney arch of inclination and the angle of horizontal plane are preferably 10 ° between 5-15 °.The forward terminal of back chimney arch is equal with the aft terminal height of preceding chimney arch, and existing therebetween spacing distance constitutes air port 15.Chimney arch 9 on upper furnace is provided with.Before chimney arch, back chimney arch and last chimney arch cooperate acting in conjunction, make the utlity model has coal adaptability by force, be easy to light a fire, sufficient combustion, minimizing pollution, characteristics that the thermal efficiency is high.
On the body of heater 12 above the chimney arch 10 of back, have secondary air mouth 11, combustion-supporting first, second can adjust the temperature of exporting hot blast.
