Abstract

The utility model relates to an efficient clean-type coal circulatory combustion direct gasification oven, which comprises an oven body, wherein the middle part of the oven body is a hearth, and the lower part of the oven body is an ash bin; a thermal insulation jacket is arranged outside the hearth, and a combustion chamber is arranged inside the hearth; an air collection chamber is arranged at the upper part of the combustion chamber, and a circulatory combustor is arranged at the lower part of the combustion chamber; oxygen feed openings are arranged at the top of the air collection chamber; an air adjustment inserted board is arranged inside the ash bin, and fire bars are placed on the air adjustment inserted board; a dustproof cover is installed at a mouth of the oven; and the combustion chamber, the circulatory combustor, a mixed gas passage, a fuel gas passage, an adjustable air inlet and the air collection chamber are communicated. The efficient clean-type coal circulatory combustion direct gasification oven has little pollution and high combustion efficiency, and consumes less fuel; the fuel price is low; further, the oven remarkably saves the energy, reduces the emission and lowers the consumption.

Description

High effect cleaning moulded coal circulating combustion direct gasification stove and accessory

Technical field

The utility model relates to circulating combustion direct gasification technology.

Background technology

The supporting combustion heat energy utilization rate of China's clean moulded coal and stove and accessory is low at present, and the poor heat stability of moulded coal produces a large amount of dusts in the process of blowing, and clean coal is unholiness in the process of burning.The primary raw material of China's heat energy is a coal, and along with demand for energy increases, energy supply is also nervous thereupon.Common cooking stove on the market both wasted energy now, again atmosphere was had very big pollution.

Summary of the invention

The purpose of the utility model is to provide high effect cleaning moulded coal circulating combustion direct gasification stove and accessory, can make the clean more burning of moulded coal, in the process of burning, does not blow ash; Reduce exhaust gas discharging; Realize the chimney zero-emission, realize dual solid sulphur, improve the heat energy utilization rate.

The technical scheme of the utility model is following: high effect cleaning moulded coal circulating combustion direct gasification stove and accessory, comprise body of heater, and the body of heater middle part is a burner hearth; The body of heater bottom is grey storehouse; It is characterized in that outside burner hearth, being provided with muff, in burner hearth, be provided with the combustion chamber, be provided with collection chamber on top, combustion chamber; Be provided with cyclic burner in the bottom, combustion chamber, the collection chamber top is provided with send the oxygen hole; Be provided with in the ash storehouse and transfer the wind plate, transfer on the wind plate and be placed with fire bars; Fire door is equipped with dust cover; Combustion chamber, cyclic burner, mixed gas passage, blast tube, adjustable air inlet and collection chamber are connected.

Between burner hearth and muff, form the heating water jacket, be provided with delivery port, be provided with water inlet in the heating water jacket bottom on heating water jacket top.

Between mixed gas passage and muff, form the flue residue heat water jacket, be provided with delivery port, be provided with water inlet in flue residue heat water jacket bottom on flue residue heat water jacket top.

The utility model is the characteristics according to clean moulded coal, manufactures and designs the combustion stove of specialty, cyclic burner and dust cover has been installed, waste heat repeated combustion and utilization; What blow is overfire air, and heat energy loss is low, and adjustable rectification campaign amount; Therefore control flame can practice thrift mass energy, improves the heat energy utilization rate; Make clean moulded coal completing combustion as clean as a penny, the protection environment reduces the burning cost.

It is little that the utility model pollutes, and efficiency of combustion is high, and consume fuel is few, at the bottom of the fuel price, energy-conservation, reduce discharging, consumption reduction obviously.

Description of drawings

Fig. 1 is the utility model overall structure sketch map.

The specific embodiment

Be described in detail below in conjunction with the content of accompanying drawing the utility model.

As shown in Figure 1; During use, with heating water jacket 3 and flue residue heat water jacket 10 interior topped up with water, then the wood fragments material is put into combustion chamber 5 and light earlier; Moulded coal is positioned on the fire bars 4; Power-on start cycles burner 6, adjustment mixed gas passage 7, blast tube are chimney 8, adjustable air inlet 9, send oxygen hole 13, transfer wind plate 16, and method of operating and common stove and accessory are basic identical.Each auxiliary function is controlled as required.

Clean moulded coal changes into heat energy after 5 burnings of combustion chamber, the water in the heating water jacket 3 heats naturally, and delivery port 1 is discharged the water Automatic Cycle of heating; Water inlet 2 is sent into running water, and cyclic burner 6 is forced waste heat is introduced combustion chamber 5, and mixed gas passage 7 is regulated the air proportionings; Blast tube 8 is that chimney is discharged waste heat, adjustable air inlet 9 be the spontaneous firing exhaust opening be again the forced burning air inlet, from water inlet 18 topped up with water in flue residue heat water jacket 10; Delivery port 17 is discharged the water Automatic Cycle of heating, and flue residue heat water jacket 10 utilizes the water in the water jacket that the hot gas that reclaims is cooled off, and reduces the hot air temperature through cyclic burner 6; Gas that collection chamber 11 collection combustion chambers 5 produce in combustion process and the oxygen that send oxygen hole 13 to carry are transported to blast tube 8 with the two afterwards, and dust cover 12 stops dust to be discharged; Can with part flame stop downward entering combustion chamber 5 again backfire once make burning more abundant, send oxygen hole 13 can adjust collection chamber 11 oxygen contents; Muff 14 not losses of protection heat energy; And can reduce indoor temperature, grey storehouse 15 storage ashes are transferred wind plate 16 to regulate and are given air quantity.

This stove and accessory is equipped with cyclic burner 6, impels thermal source constantly to circulate, and the incendivity thing is thoroughly burnt; Stove and accessory has a plurality of oxygen holes 13 of sending can adjust oxygen-supplying amount, controls required heat-source energy; Blast tube 8 is that the natural air inducing of chimney combines with cyclic burner 6, regulates from the amount of the mist of adjustable air inlet 9 and collection chamber 11 entering mixed gas passages 7, has changed oxygen supply airflow direction and residual neat recovering system, and the fire door dust is few, clean hygiene.

The utility model can externally steam, boils, bathing, heating, refrigeration auxiliary equipment, reaches multi-use.
