Abstract

The utility model discloses a multifunctional coal-saving stove for civil use. The utility model is additionally provided with a layer of jacket on the outer side of a stove body of the ordinary coal stove for civil use, and a flue port of a stove chamber at the upper part of the stove body is provided with a heat-absorbing water jacket which is communicated with the jacket on the outer side of the stove body. Heat-absorbing water pipes in vertical staggered arrangement are arranged in the heat-absorbing water jacket, and two ports of the heat-absorbing water pipes are communicated with the heat-absorbing water jacket. A flue is arranged between the heat-absorbing water pipes, and the heat-absorbing water pipes and the heat-absorbing water jacket are heated by flame; cold water enters a cold water inlet on the jacket of the outer side of the lower part of the stove body to be primarily heated and then enters the heat-absorbing water pipes and the heat-absorbing water jacket, and finally is discharged from a hot water outlet. The utility model can be used for heating and cooking for civil use, and has the advantages of simple structure, normal-pressure operation and high thermal efficiency.

Description

Multi-functional coal-saving stove

The utility model relates to a kind of civil stove and accessory, specifically is exactly a kind of multifunctional civil coal-saving stove.

Be the life use stove tool of fuel with coal in the prior art, mostly be vertical, round, by the heating of flue absorption portion residual heat heating gas sheet, utilization rate of waste heat is low, causes heat waste, and delivery port water level height, the water circulation is not smooth, and the warming stove that has needs to install and use inconvenience by hair-dryer and water circulating pump, a complete set of stove and accessory cost is higher, and application is restricted.

The purpose of this utility model is to provide a kind of thermal efficiency higher, energy savings and multifunctional civil coal stove simple in structure, that cost is low, and it can be used for the usefulness of heating and cooking.

The purpose of this utility model is to realize like this, body of heater is a drum type, one deck chuck is established in the outside, furnace lining refractory material heat-insulation layer is set up a heat absorption water jacket at the top of body of heater hearth box floss hole, and the heat absorption water jacket communicates with the chuck in the body of heater outside, in flue, be provided with vertical staggered heat-absorbing water pipe, the two ends of heat-absorbing water pipe communicate with the heat absorption water jacket, and heat-absorbing water pipe is interspersed, and helps absorbing the heat of flue flame.On the heat absorption water jacket, be provided with hot water outlet, on the chuck in the outside, body of heater bottom cold water inlet is arranged, cold water enters in the chuck in the body of heater outside from this inlet, after preliminary heating, enter in the heat absorption water jacket and heat-absorbing water pipe on the flue, continued heating by flue flame, after hot water outlet enters heating system, enter cold water inlet circulation heating after the heat release again, flue flame passes through between vertical staggered heat-absorbing water pipe pipe in the flue, through chimney cigarette is discharged, and chimney is located at of heat absorption water jacket.

In order fully to absorb the heat of flame in the flue, will make flat near the heat-absorbing water pipe of chimney, help the absorption of flame waste heat, promptly be unlikely to allow chimney be taken away the flame waste heat is too fast.

Certainly also can one firestopping piece be set for achieving the above object near chimney and towards flame direction.

In order to guarantee flame as far as possible delay some times in flue, to the heat-absorbing water pipe heating, the summation of flue area should be greater than the sectional area of chimney between heat-absorbing water pipe in design more.

Below in conjunction with accompanying drawing and the embodiment that provides the utility model is further described.

Accompanying drawing 1 is structural representation of the present utility model (analysing and observe).

Accompanying drawing 2 is vertical views of the present utility model.

As depicted in figs. 1 and 2, body of heater 6 is a drum type, in its outside one deck chuck 12 is arranged, furnace lining refractory material heat-insulation layer 11, be provided with a heat absorption water jacket 3 at floss hole 2 places of the top of body of heater hearth box, it is welded on the outside of flue, or with a cast molding of body of heater, (or in the water jacket that claims to absorb heat) has the vertical staggered heat-absorbing water pipe 13 of three rows on flue, these heat-absorbing water pipe upper and lower openings communicate with heat absorption water jacket 3, therefore the slit between heat-absorbing water pipe has formed flue, flame is being discharged cigarette by chimney 5 heat-absorbing water pipe 13 heating backs, and chimney 5 is at the external end head of heat absorption water jacket, near 14 one-tenth flat of heat-absorbing water pipe at chimney 5 places, be also referred to as fireguard, it also is a hollow, and upper and lower opening communicates with the heat absorption water jacket, and cold water enters in the chuck 12 in the body of heater outside from water inlet 7, enter again in heat absorption water jacket and the heat-absorbing water pipe through preliminary preheating, further heated after chimney 5 is discharged cigarette by flue flame.Coal-fired from fire door 1 adding, the 9th, fire grate, thin ash is drawn out from ash hole 8,10 be slag outlet be again air inlet, if when cooking, bell is opened with it, flue valve sealing or semiclosed, during heating, cover bell, the aperture on the bell blows into secondary wind fully burns to heat absorption water jacket and heat-absorbing water pipe heating coal.When banking up a fire, the air inlet of body of heater bottom is closed, seal up coal slime or broken coal, middle bundle one aperture covers bell and gets final product.

This stove can burn lump coal, broken coal and multiple coal, but the equal normal combustion of common excellent coal.

The utility model is simple in structure, making is easy, cost is lower, general about 90 yuan every, its combustion thermal efficiency height is through test, 200Kg water can be heated to 90 ℃ of delivery port water temperatures in 2 hours after lighting with the 5Kg coal, return water temperature is more than 50 ℃, and normal pressure work does not have specific (special) requirements to material, be a kind of coal-saving domestic stove, apply easily with multiple function.

Claims (4)

1, a kind of commercial coal stove that constitutes by body of heater 6, fire grate 9 and flue, hearth box floss hole 2 places, top that it is characterized in that body of heater 6 are provided with a heat absorption water jacket 3, it communicates with the chuck 12 in the body of heater outside, in flue, be provided with vertical staggered heat-absorbing water pipe 13, the two ends of heat-absorbing water pipe communicate with heat absorption water jacket 3, on the heat absorption water jacket 3 hot water outlet 4 being arranged, is passage of flame between heat-absorbing water pipe, and chimney 5 communicates with flue.
