Description

Civilian heat supply stove

The utility model relates to civilian heating stove and accessory.

Present civilian heating stove and accessory is to set up water jacket on general stove and accessory, and water jacket links to each other with heating equipment, and its weak point is that combustion rate is low, and the thermal efficiency is low, pollutes heavy.

The purpose of this utility model is to provide a kind of and has combustion rate height, thermal efficiency height, pollutes the light stove and accessory that heats of being suitable for specially.

The utility model comprises the stove seat, the spray dish, fire bars, chimney and annular steam chamber, the annular steam chamber links to each other with the spray dish by pipe, it is characterized in that the outdoor cross section that is covered with successively of annular steam is for the steam generating chamber and the cross section of " U " shape are the preheating water tank who falls " U " shape, steam generating chamber and preheating water tank are provided with coal filling hole, in the annular steam chamber, form " U " shape flue between steam generating chamber and the preheating water tank, chimney is located on the preheating water tank, the annular steam chamber, being provided with pipe between steam generating chamber and the preheating water is connected, steam generating chamber is provided with the heating outlet pipe, and the preheating water tank is provided with return pipe.

Above-mentioned heat supply stove, the pipe that the annular steam chamber is connected with steam generating chamber is provided with control valve.

Above-mentioned heat supply stove, the pipe other end that is connected with the spray dish stretches into the annular steam chamber.

Above-mentioned heat supply stove, preheating water tank's inwall is provided with heat absorbing sheet, and its top extends upward and forms a water jacket that is wrapped in outside the chimney.

Because of the utility model is steam generating chamber and the preheating water tank of cross section for falling " U " shape who falls " U " shape in the outdoor cross section that is provided with of annular steam, make burner hearth be in a relative closure state, stove fire directly heats steam generating chamber, quicken the formation of water vapour, after entering the annular steam chamber, the water vapour that forms further heated, make between the hydrone separate more thorough, improved the production rate of water-gas, thereby improved the burning of coal rate, reduced energy consumption, alleviated pollution, when 800 ℃ of stove Nei Wenduda, water and iron reaction generate hydrogen, and hydrogen is the instead of part coal combustion directly, make energy consumption and pollute further the reduction; Secondly, " U " shape flue that forms between annular steam chamber, steam generating chamber and preheating water tank can absorb waste heat, improves furnace thermal efficiency, if at preheating water tank's inwall heat absorbing sheet is set, its top connects one and is wrapped in the outer water jacket of chimney, and then thermal loss still less; In addition, also can provide bathing water at the indoor spiral heat exchange tube that is provided with of steam generation.The utlity model has that structure is tightly played, lightweight advantage, be suitable for rural area, building site, the frontier sentry heat supply in winter of central heating inconvenience.

Figure is described in detail the utility model below in conjunction with symbol.

Fig. 1 is the structural representation of the utility model embodiment.

With reference to Fig. 1, annular steam chamber (11) is set on the stove seat of the present utility model (1), establish fire bars (16) in the annular steam chamber (11), the outer cross section that is covered with successively, annular steam chamber (11) is for the steam generating chamber (12) and the cross section of " U " shape are the preheating water tank (8) who falls " U " shape, steam generating chamber (12) and preheating water tank (8) are provided with coal filling hole (13), in annular steam chamber (11), form " U " flue between steam generating chamber (12) and the preheating water tank (8), chimney (6) is located at preheating water tank (8) top, preheating water tank (8) inwall is provided with along the vertically disposed heat absorbing sheet of circumference (17), preheating water tank (8) top extends upward to form and is wrapped in the outer water jacket (6) of chimney (5), preheating water tank (8) links to each other with steam generating chamber (12) by pipe (9), steam generating chamber (12) links to each other with annular steam chamber (11) by pipe (2), pipe (2) is provided with control valve (3), annular steam chamber (11) links to each other with spray dish (10) by pipe (15), pipe (15) one ends stretch into annular steam chamber (11), its end sealing, have air admission hole (14) on the wall, steam generating chamber (12) is provided with heating outlet pipe (7), and preheating water tank (8) is provided with heating water return pipe (4).
