Abstract

The utility model relates to an efficient energy-saving stove, which is composed of a water jacket of a stove chamber, a heat absorption circulation water pipe in a horizontal downward turning fire bending type water jacket flue of a heat absorption circulation water pipe by an upper layer and a lower layer in a stove chamber of a quick heating water ring, a secondary combustion structure, etc. The horizontal folding type water jacket flue of the stove can make use of heat energy sufficiently; a water sandwich partition wall in the flue and the heat absorption circulation water pipe can absorb heat energy sufficiently. Meanwhile, the utility model can make dust carried by flue gases clung to the flue for reducing the environmental pollution. The secondary combustion can make fuel sufficiently combusted for achieving the energy saving effect. The stove can save coal by 60% compared with a vertical water jacket type heating stove of a simplex stove chamber water jacket.

Description

Efficient energy-saving furnace

The utility model relates to the equipment that a kind of heating is used, and it is to be pyrotoxin with lump coal, is the hot-water heating stove of the high-efficiency and energy-saving type of medium with recirculated water.

At present, existing hot-water heating stove is compared with old traditional stove, has increased water burner hearth and vertical shredded tobacco for water pipes road, is used for family's heating.But this hot-water heating stove coal consumption is big, and heat supply speed is slow, and the thermal efficiency is low, and coal fires endless, causes energy waste and environmental pollution.Simultaneously also brought financial burden to the user.

This practical purpose is to cancel above-mentioned unfavorable factor and shortcoming, alleviates energy shortage, and shortage of resources is strengthened condition.So that solve the heat supply problem of vast residential houses and part office space, and it is energy-conservation to accomplish to economize coal in a large number.

The purpose of this utility model is achieved in that the steel plate with 3 millimeters thick bends through stamping-out, and welding after operations such as calendering are shaped processes a series of component parts by the drawing design, and wherein bell has adopted ironcasting, is assembled into stove.

This stove removes has common hearth water sleeve (1), fast Circle device for heating water (8), outside the flue water jacket, increased the second-time burning structure in the design, horizontal collapsible flue water jacket of downward-turning fire and heat absorption circulating water pipe (11), in the second-time burning flue, be provided with the adjustable valve of control second-time burning, and be provided with two shoot doors (16) in horizontal flue outer end.The second-time burning structure is to be provided with two-layer heat absorption circulating water pipe (4) (6) under the fast Circle device for heating water (8) in burner hearth, and two-layer heat absorption circulating water pipe (4) (6) plays the function of fire grate again, and this just forms two burner hearths up and down in burner hearth.The caliber and the spacing of upper strata heat absorption circulating water pipe (6), all greater than the caliber and the spacing of lower floor heat absorption circulating water pipe (4), the most fuel second-time burning in lower floor's burner hearth of unburned that fuel is absorbed heat by the upper strata and leaks down between circulating water pipe (6) in upper strata burner hearth internal combustion earlier, in the middle of two-layer heat absorption circulating water pipe, be provided with adjustable shutter (5) on the furnace wall, required oxygen when supplying with two burner hearth fuel combustions.Upper strata burner hearth pyrotechnics upwards flows into the collapsible flue of horizontal downward-turning fire, the pyrotechnics of lower floor's second-time burning burning downwards enters the second-time burning flue, laterally folded formula flue and the junction of upper strata pyrotechnics have been entered again by second-time burning adjustable valve (17), the structure of second-time burning is burnt fuel completely, has realized energy-efficient purpose.

Laterally the structure of the collapsible flue water jacket of downward-turning fire is, laterally setting up a vertical water interlayer partition wall and two horizontal water interlayer partition walls (10) in the water-jacket typ flue, the flue gas laterally folded again walking of walking downwards earlier that burner hearth is come out, under two-layer horizontal water interlayer partition wall, be provided with heat absorption circulating water pipe (11), this kind structure, the high temperature pyrotechnics heat that burner hearth can be come fully absorbs, and the hot water temperature that burner hearth is come improves once again, and heat is fully utilized.

Owing to turn over and bend walking under the flue gas, effective sedimentation of dust energy of carrying in the flue gas or apposition are in horizontal flue, and dust can regularly be removed from two shoot doors (16), so just significantly reduce the pollution to environment.

This stove structure is both artistic and practical, and technical parameter is reasonable.

Because adopt such scheme, this stove has realized that programming rate is fast, UTILIZATION OF VESIDUAL HEAT IN is abundant, thermal efficiency height.Through using it to economize on coal 60%, create huge economic benefit and social benefit than the warming stove of the vertical flue water-jacket typ of simple hearth water sleeve.This stove can also be taken into account cooking and shower simultaneously at heating, is subjected to users' favorable comment deeply.

Below in conjunction with accompanying drawing the utility model is further specified: Fig. 1 is that the energy-efficient furnace structure of the utility model is always schemed.Fig. 2 is the laterally folded formula flue of the interior fast Circle device for heating water upper strata heat absorption circulating water pipe of the burner hearth water sleeve heat absorption circulating water pipe structure chart of the utility model efficient energy-saving furnace.Fig. 3 is I-I profile of Fig. 1.

Among the figure, 1, hearth water sleeve; 2, water inlet; 3, burner hearth cleaning door; 4, lower floor's heat absorption circulating water pipe; 5 adjustable shutters; 6, upper strata heat absorption circulating water pipe; 7, cobbings door; 8, fast Circle device for heating water; 9 bells; 10, water interlayer partition wall; 11, heat absorption circulating water pipe in the flue; 12, delivery port; 13 chimneys; 14, chimney hold-down screw; 15, cleaning door; 16, shoot door; 17, second-time burning flue adjustable valve.

This efficient energy-saving furnace need be installed with the radiator pipe arrangement and form the heat supplying loop use.Because whole system is by Natural Circulation, and why Natural Circulation can realize, is because the water temperature variation can produce the bulk water pressure head, wants to keep system to circulate smoothly, must make the radiator position of center line be higher than burner hearth center line certain size.Replenisher tank must be arranged in addition and, must not arbitrarily adorn pipe valve, guarantee that pipeline is unimpeded, reduce resistance as far as possible at highest point dress atmospheric valve.
