The hearth wall is sheathed in the stove casing, a spacer region is arranged between the hearth wall and the stove casing, a chimney interface is arranged at a point where positioned a little bit above the centerline of the stove casing, and a stove casing water jacket is connected with the upper part of a chimney water jacket by a connecting pipe. The utility model has the advantages of complete combustion, high thermal efficiency and few smoke discharge, and local overheat in the water jacket is avoided.

Description

Heating stove

The utility model belongs to coal combustion furnace, is a kind of warming stove that intercalated water sleeve is arranged that is used for family's heating.

Present family's warming stove, stove outer covering and burner hearth are one, and there is intercalated water sleeve the centre, and the water heat absorption is fast, causes fire box temperature to descend, and stove fire is difficult for reaching a high temperature.Chimney interface is on stove outer covering top, and flare is siphoned away by chimney after arriving the kitchen range bottom immediately, the kitchen range bottom inequality of being heated, and the flame RT is short, thereby reduces the thermal efficiency.The inequality because stove or chimney are heated, it is overheated that stove inner water sleeve and chimney water sleeve produce partial water, is commonly called as " Xiangshui County ", very easily causes danger.

The purpose of this utility model is: design a kind of sufficient combustion, kitchen range are heated evenly, and smoke is few, overcome family's warming stove of local heating.

The purpose of this utility model is achieved in that the stove outer covering that water jacket is installed on the base of warming stove, and hearth wall is arranged in it, also is connected to the chimney of band water jacket on the stove outer covering.Hearth wall is sleeved in the stove outer covering, between stove outer covering and hearth wall spacer region is arranged, and flue gas moves around burner hearth in spacer region.Chimney interface on the stove outer covering is located slightly on the upper side at the stove outer covering center line.The water jacket top of stove outer covering is connected with tube connector with chimney water sleeve top, makes tube connector and two water jackets form a loop.

The utlity model has following advantage: coal burning is abundant in the stove, and smoke is few, has saved the energy, forms loop with tube connector, has avoided hot-spot.According to experiment showed, that the thermal efficiency can improve more than 45%.

Description of drawings.Fig. 1 is the utility model cutaway view.

Below in conjunction with the drawings and specific embodiments structure of the present utility model is described in detail.The stove outer covering 3 of water cover 4 is installed on the base 1 of warming stove, hearth wall 5 is arranged in the stove outer covering 3, the stove outer covering 3 external chimneys 11 that have water jacket 9, hearth wall 5 is sleeved in the stove outer covering 3, between stove outer covering 3 and the hearth wall 5 spacer region 16 is arranged, flue gas flows around hearth wall in spacer region 16.Chimney 11 is located at the center line of stove outer covering 3 slightly on the upper side with the interface 15 of stove outer covering 3.The top of the water jacket 4 of stove outer covering 3 links to each other with tube connector 8 with the top of the water jacket 9 of chimney 11, makes water jacket 4, water jacket 9 and tube connector 8 form loop.When using the warming stove of this utility model, by water inlet pipe 12 water is injected in water jacket 4 and the water jacket 9 earlier, enter heating gas, get back to water inlet pipe 12, form a circulatory system from heating gas by outlet pipe 10.Light the coal in hearth wall 5 internal furnaces then, coal takes fire, and wind enters from bottom slag notch 14, and stove fire rises from crater 7 straight lines of hearth wall 5 napexes, arrives the kitchen range bottom on kitchen range mouth 6, makes kitchen range bottom thermally equivalent comprehensively.Stop that through the kitchen range bottom mixing hot-fluid of fire smoke gases flows from middle mind-set hearth wall 5 external diffusions, is heated inside and outside the hearth wall 5 from top to bottom, kept the interior temperature of burner hearth constantly to raise.Hot-fluid is when the bottom of the spacer region 16 that arrives stove outer covering 3 and hearth wall 5 centres, be obstructed once more, be subjected to the chimney suction affects, hot-fluid flows to the interface 15 of chimney 11 with stove outer covering 3 along hearth wall 5, and unburnt combustible gas cognition is mixed with remaining oxygen in spacer region 16, burns away, because increase burning time, make sufficient combustion, combustion rate improves, and has reduced the discharge rate of flue gas.At this moment, by the water in the heat conduction heating water jacket 4.Flue gas arrives chimney 11 interfaces 15 along hearth wall 5, enters chimney 11 from interface 15, and waste heat makes the water jacket 9 interior water of chimney 11 be heated, and hot water enter the circulatory system by outlet pipe 10 in water jacket 4 and the water jacket 9, reach the heating purpose.The warming stove of prior art is when stove burns, because of local heating, local temperature is too high in water jacket 4 or the water jacket 9, the water boiling produces " Xiangshui County ", the utility model connects into loop with tube connector 8 with water jacket 4 and water jacket 9, make the water of local heating in time obtain circulation, " Xiangshui County " phenomenon of having eliminated the partial water boiling and having produced, flue gas is at chimney 11 and stove outer covering 3 interfaces 15 place's reducings, increased resistance, dust has been descended, on base 1, leave cleaning door 13 on the interface 15 below spacer regions 16 bottom oven shells 3 of chimney 11, after a while in-furnace dust dirt is walked clearly.Because of the pollution in the not pure and mild circulatory system of water quality, produce dirt in the water jacket, sewage valve 2 is set in time removes.Behind the coal combustion, cinder is discharged from slag notch 14 in the stove.
