Abstract

The utility model relates to an improved domestic hot water heating stove which comprises a stove chamber of a stove body, a stove fire pipe, a water jacket, a water inlet and outlet pipe opening, etc. The utility model is characterized in that a layer of heat-insulation material is arranged between the stove chamber and the water jacket; the diameters of a plurality of stove pipes increase following the increase of the distance from a chimney; the sizes of openings which are arranged on a ceiling and are used for fixing the stove pipes also change correspondingly. The utility model has the advantages of high stove chamber temperature, complete and stable combustion, good fire extinction resistance, uniform heat conduction effect and high heat efficiency, decreases black smoke and reduces pollution.

Description

Efficient domestic heating water heater

The utility model relates to a kind of improved domestic heating hot-water boiler, the domestic heating hot-water boiler that particularly a kind of thermal efficiency is very high.

Along with the raising of living standards of the people, require the people of heating more and more, but the condition that always has quite a few family not possess central heating can only be carried out heating with the domestic heating water heater.

Existing domestic heating hot-water boiler, generally be to add a water jacket in the burner hearth outside, heating fuel (mainly referring to coal here) burning liberated heat is passed to hot water in the water jacket by hearth outer wall, its shortcoming is that this stove is because directly from the burner hearth heat-obtaining, will inevitably reduce fire box temperature, this will cause insufficient, the unstable and fire extinguishing easily of fuel combustion, also can cause chimney over-emitting black exhaust, atmosphere pollution.Another deficiency of prior art is that the thermal efficiency is low, can not fully be absorbed by stove water because leave the heat of the high-temperature flue gas behind the burner hearth, and many heats are run away from chimney in vain.The cooking ability is not high yet.

The purpose of this utility model provides the high novel domestic heating water heater of a kind of thermal efficiency, it can fully burn coal, change chemical energy wherein into heat energy to greatest extent, and these heat energy are passed in the stove water as much as possible go, reach energy savings, reduce the hot water heating operating cost, reduce the purpose of black smoke atmosphere pollution.And overcome the easily shortcoming of fire extinguishing of combustion instability.

Above-mentioned purpose is achieved by the following technical solution, existing in conjunction with the accompanying drawings and embodiment to be illustrated Fig. 1 be facade, Fig. 2 is a plane, its structure is as follows:

It comprises urceolus [1], base plate [2], lower plate [3], insulation material [4], inner core [5], hearth wall [6], boiler tube [7], effluent pipe mouth [8], card [9], top board [10], water inlet pipe mouth [11], fire bars [12], fire door [13], bell [14], chimney [15], burner hearth [16], furnace roof cavity [17], fume collecting chamber's parts such as [18].

Of the present utility model being characterised in that between the cylindrical of burner hearth [6] and water jacket is provided with one deck insulation material [4], this has just increased the thermal resistance between burner hearth and the stove water greatly, reduced the heat output of burner hearth to stove water, thereby improved fire box temperature, create good temperature conditions for the burning of fuel [16], guaranteed the completing combustion of fuel.And flame is vigorous.Because what the heat in the burner hearth passed away lacks, also make furnace roof cavity [17] locate very high temperature, when the bell on opening top board [10] is cooked and is boiled water, just have very prosperous firepower, thereby having improved the cooking ability of this stove greatly, flame that produces in the coal combustion process and high-temperature flue gas are entered the upper end of boiler tube [7] by furnace roof cavity [17], and then the boiler tube [7] of flowing through downwards collects in the fume collecting chamber [18], at last by flue [15] row to atmosphere.

In fume collecting chamber [18], from the near more cigarette joint of chimney [15], suffered draft is big more, if all smoke pipes [7] diameter is equal fully, it is big the draft that is subjected to by the nearer smoke pipe of chimney to occur, flow velocity height wherein, the draft that smoke pipe at a distance is subjected to is little, the phenomenon that flow velocity wherein is low, will cause flue gas flow imbalance in each smoke pipe like this, thereby cause the heat output imbalance in each smoke pipe, caused the deviation of heat output, influence furnace efficiency.

In order to overcome this shortcoming, the utility model will be nearer apart from chimney smoke pipe, make with thinner steel pipe, when flue gas was flowed through it, resistance was bigger, and make with thicker steel pipe apart from chimney smoke pipe far away, make its resistance less, thereby overcome because of do not wait deviation on the heat output that causes from the chimney distance, heat-transfer effect is even on the whole to guarantee this stove, perforate size on card [9] also will be done corresponding the adjustment and change, and fixes the different boiler tube of size.

The utlity model has following effect: in high-temperature flue gas is flowed through the process of smoke pipe [7], because the outside of smoke pipe [7] is the lower stove water of temperature, so it is to make with the very high steel pipe of thermal conductivity factor that very big heat transfer temperature and pressure smoke pipe [7] is arranged, can make the most of heats in the high-temperature flue gas pass to stove water, thereby improve the thermal efficiency of this stove.Reduced heat loss due to exhaust gas,, reduced the pollution of black smoke atmosphere because fuel combustion is complete.Again since interior the side contacts of this furnace outer wall [1] be stove water, so this wall temperature is lower, the radiation loss that this has just reduced body of heater makes furnace thermal efficiency raising; The smoke pipe of design different size diameter can make and conduct heat evenly, improves heat-transfer effect.

In addition, this stove has also designed appropriate coal seam height, and coal is fully burnt, and can make full use of coal again, and the waste heat of lime-ash gives hot combustion air, so not only can improve fire box temperature, has also reduced the loss of discharging lime-ash, has improved the thermal efficiency of this stove.

Claims

1. an efficient domestic heating water heater comprises parts such as furnace wall, burner hearth, hot water jacket, card, stove fire pipe, the Inlet and outlet water mouth of pipe, bell fire bars, chimney outlet, it is characterized in that:

A. between the cylindrical of burner hearth [6] and water jacket, be provided with one deck insulation material [4],

B. the diameter dimension of stove fire pipe [7] changes along with the distance that exports from chimney, and apart from more then caliber is littler, distance more then size heals greatly,

C. the perforate size on the card of stationary furnace fire tube [9] is also done corresponding change along with the size difference of stove fire pipe.
