Abstract

The utility model relates to a vertical clean steam and water boiler by burning the coal, which is composed of a boiler body, a boiler chamber, a grate, and a smoke window. The boiler body comprises an outer internal boiler and an inner internal boiler. The inner and the outer internal boilers are communicated by an upper and a lower circulating pipes. An air supply piping system unit is arranged below the boiler body, and a combustion chamber communicated with the boiler chamber is arranged above the boiler body. The middle zone in the combustion chamber is fixedly provided with a water jacket for shielding the dust and absorbing the heat. When in use, the utility model can cause the gasification and the combustion of the coal to be combined into integration, the charcoal with the combustibility can obtain the sufficient combustion, the discharge amount of the dust can be reduced, and the problem of the environmental protection can be solved.

Description

The clean steam-water dual-purpose stove of vertical fire coal

The utility model relates to the clean steam-water dual-purpose stove of a kind of vertical fire coal.

The present coal-fired steam-water dual-purpose stove that uses of China, the smoke dust discharge concentration height, environmental pollution is serious, needs adapted air-introduced machine and cleaner, take up room so big, equipment is many, and the effect of smoke evacuation dedusting is undesirable, the environmental protection requirement that incompatibility is current.

The purpose of this utility model provides the clean steam-water dual-purpose stove of vertical fire coal of a kind of energy-saving and smoke-removing, dedusting.

For achieving the above object, the utility model is taked following design: the clean steam-water dual-purpose stove of a kind of vertical fire coal, constitute by body of heater, burner hearth, fire grate and smokestack, described body of heater comprises outer furnace, inner furnace, interior outer furnace communicates by upper and lower circulating water pipe, the air supply duct system unit is arranged below body of heater, comprising:

A blowing unit body is made of a wind conveying pipe that has air intake pipe orifice.

The secondary blast cell cube, comprise an air intake pipe orifice and with some secondary wind conveying pipes of its UNICOM, these some secondary wind conveying pipes again be positioned at the ring-type triangle wind storehouse UNICOM of fire grate top along the outer furnace inner wall surrounding, on triangle wind storehouse, have some wind hole;

Three blowing unit bodies by the direct UNICOM of air intake pipe orifice tertiary air loop pipe, lead to hearth body through the tertiary-air pipe that is arranged in the outer furnace of UNICOM again; Tertiary-air pipe and hearth body connection position are provided with nozzle;

Establish a combustion chamber that communicates with burner hearth above body of heater, zone line fixedly installs the water jacket of dust-break heat absorption in the combustion chamber.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is a structural representation of the present utility model

Fig. 2 is the B-B profile of Fig. 1

Fig. 3 is the C-C profile of Fig. 1

Fig. 4 is the A-A profile of Fig. 1

As shown in Figure 1 and Figure 2, the utility model is made of body of heater 1, burner hearth 2, fire grate 3, smokestack 4, air supply duct system unit and combustion chamber 5.

Body of heater 1 comprises outer furnace 101, inner furnace 102, and interior outer furnace communicates by upper and lower circulating water pipe 103,104.

The setting of burner hearth 2, fire grate 3, smokestack 4 is prior art, is not repeated herein.

Characteristic point of the present utility model is to be provided with the air supply duct system unit below body of heater, with reference to Fig. 1, Fig. 3, shown in Figure 4, it comprises:

A blowing unit body is made of a wind conveying pipe 602 that has air intake pipe orifice 601.Be balanced ventilation, the wind conveying pipe port also can connect a ring 603.

The secondary blast cell cube, comprise that an air intake pipe orifice 701 reaches and some secondary wind conveying pipes 702 of its UNICOM, these some secondary wind conveying pipes 702 again be positioned at fire grate top ring-type triangle wind storehouse 703 UNICOMs along the outer furnace inner wall surrounding, have intensive wind hole 7031 on the wind storehouse, the wind hole is towards top, burner hearth center.

Three blowing unit bodies by air intake pipe orifice 801 direct UNICOMs three air-supplies loop pipe 802, lead to hearth body through the tertiary-air pipe 803 of UNICOM again; Tertiary-air pipe 803 is provided with nozzle 804 with the hearth body connection position, and each nozzle can be fixing by the direction of setting (being a fixed inclination), makes the wind of ejection rotate naturally.

Combustion chamber 5 central areas above body of heater fixedly install the water jacket 9 of dust-break heat absorption.Combustion chamber 5 communicates with burner hearth by smoke pipe 11.

Be equipped with louver 10 on the air intake pipe orifice of above-mentioned one, two, three blowing unit body, it can control the size that enters air quantity.

Operation principle of the present utility model is: in the air supply duct system unit, a blowing unit body is through louver balanced ventilation under fire grate, impel the coal combustion on the fire grate, the plurality of pipelines of secondary blast cell cube is blown to triangular form wind storehouse, intensive wind hole blows out and forms intensive air curtain net to center, burner hearth top above triangular form wind storehouse again, unburnt charcoal in the coal, the fuel gas through burn incompletely produces mixes burning again under the secondary air curtain.Three times the blowing unit body rotates cloth wind by nozzle by the certain height angle direction near hanging courage, forming oxygen-enriched air film and unburnt imflammable gas fully mixes, form distinctive gas-fired on the top, combustion chamber, flammable charcoal in the combustion chamber is fully burned produces a large amount of heats, and pass to fast and hang in the courage and the water in the flue all around, thereby improved the thermal efficiency of this stove.Dust-break, heating water jacket's device are installed in the upper of furnace body combustion chamber, and flue gas, the micronic dust of rising are here blocked by it, make flue gas produce eddy current once more, and waste heat is transmitted feedwater once more.

The utility model has the advantages that this stove combines coal gasification and burning together, flammable charcoal is filled Divided combustion. Because the choked flow effect of strong air curtain is arranged, and unburnt imflammable gas forms in the combustion chamber Distinctive gas-fired is in than stable state unburnt charcoal and grit in burner hearth, reduced dirt Discharge capacity had both solved environmental issue, had reduced again fuel cost.
