Abstract
The utility model relates to an efficient domestic water heating furnace and belongs to the technical fields of new energy and energy conservation. The efficient domestic water heating furnace comprises a hearth (1), a cooking tray (2), a plate-type heat exchanger (3), an ash bucket (4), a moving grate (5), a flue (6), an ignition heat exchange change-over switch (7), an upper flue (9) and a lower flue (8). By virtue of arranging the plate-type heat exchanger on the rear part of the water heating furnace, high-temperature fume with the temperature about 300-700 DEG C discharged out from a combustion chamber exchanges heat with heating water, and then the temperature of the fume is reduced to be less than 120 DEG C, so that the heating center of a furnace body is not lifted up while the fume heat of the heating furnace is fully recovered, the effective heat utilization efficiency of fuels is greatly improved, and environment conservation is realized while energy sources are greatly saved.
Description
Technical field
The utility model relates to a kind of small-sized efficient domestic use of water radiator, belongs to new forms of energy and field of energy-saving technology.
Background technology
The northern area that does not have central heating in China, especially samll cities and towns, rural area, domestic use of water radiator hot-water heating system (is that the body of heater internal heating surface is water jacket or water plate, an interface is respectively arranged up and down, connecing to one or more groups radiator with steel pipe, be commonly called as " native heating installation ") average service rate surpasses 30%.As the patent No. 02214424.2,02203962.7,20062001557.3,200921058254.0 etc.These cooking, heating dual-purpose stove generally are placed on the balcony of kitchen or sealing, and do not have the chimney of leakiness cigarette, and tradition uses traditional coal stove heating stove of smoke pipe heat radiation that very big progress has been arranged, and therefore, its use amount has surpassed traditional coal stove heating stove at present.
Yet because native heating installation self structure and the combustion system of banking up a fire are limit, heating efficient only is 30～40% (" the energy-conservation annual report 2012 of Chinese architecture ", Tsing-Hua University building energy conservation research centers).
Point out in " northern area part samll cities and towns building energy consumption status investigation and analysis " that University Of Tianjin's poplar Tianlin, Zhu can write: 62% resident family is individual heating in resident family of the samll cities and towns sample that seminar gathers, and " native heating installation " accounts for 38% in the individual heating, the tradition coal stove accounts for 19%, the thermal efficiency of these two kinds of heating system thermals source is all very low, is generally 30%～40%.
Find that through actual measurement limited because having Heating stove water pipe or water plate heating surface area now, exhaust gas temperature was up to 300～700 ℃ when native heating installation coal furnace very hot oven burnt, heat loss due to exhaust gas is excessive to be the low main cause of the native heating installation thermal efficiency.
Increase heat exchange area if above stove, make water jacket again, can improve Btu utilization efficient really.Add the thermal center (-tre) but can raise like this, make the forfeiture of heating hot water gravity Natural Circulation effect pressure head.
Summary of the invention
The purpose of this utility model just is to avoid above-mentioned the deficiencies in the prior art part, provides a kind of and can fully recycle the heating stove flue gas heat, does not raise body of heater simultaneously and adds the thermal center (-tre), guarantees the nondecreasing high efficiency civil hot-water heating of Natural Circulation pressure head stove.
Technical problem to be solved in the utility model is achieved through the following technical solutions:
A kind of high efficiency civil hot-water heating stove is characterized in that: described hot-water heating stove comprises burner hearth (1), cooking dish (2), plate type heat exchanger (3), ash bucket (4), moving grate (5), smoke flue (6), igniting heat exchange change-over switch (7), upper flue (9), lower flue (8); Described hot-water heating stove burner hearth (1) exhanst gas outlet is provided with a upper flue (9) and is communicated with plate type heat exchanger (3) and smoke flue (6); Described plate type heat exchanger (3) bottom is provided with a lower flue (8) and is communicated with smoke flue (6); Igniting heat exchange change-over switch (7) is set in the described smoke flue (6).
By hot-water heating stove rear portion plate type heat exchanger is set, makes the combustion chamber discharge high-temperature flue gas (about 300～800 ℃) earlier through after plate type heat exchanger and the heat exchange of heating water, enter atmosphere through chimney again.When so not only fully recycling the heating stove flue gas heat but also can not raise body of heater and add the thermal center (-tre), effectively raise the heating stove thermal efficiency.The plate type heat exchanger heat exchange area is 0.5～5 square metre, flue-gas temperature control is at 50～180 ℃ after the heat exchange, if temperature (refers to the combustion of sulfur coal after the design heat exchange more than the sour gas dew point, the biomass molding fuel sulfur-bearing is very low, need not consider the dew point corrosion problem), plate type heat exchanger can adopt the general steel plate manufacturing, otherwise, for preventing dew point corrosion, the manufacturing of preferential use corrosionproof steel against sulfuric acid at dew point, or at general steel plate inner-wall spraying resistant to sulfuric acid dew point corrosion coating, also can use common material steel plate, but it must be designed to the structure that is easy to change.
Flue gas spills into indoor when igniting heat exchange change-over switch being set effectively avoiding a some stove by high-efficiency water heating stove.
Through after the above processing, exhaust gas temperature is down to below 120 ℃, has improved fuel available heat utilization rate widely, has also protected environment when saving a large amount of energy, has responded the policy of national energy-saving and emission-reduction.

The specific embodiment
Above-mentioned hot-water heating stove changes in the hot-water heating stove any one for the radiator of just heating up water, counter heat up water radiator or positive and negative burning and cutting.
Come the utility model is further described below in conjunction with the radiator of just heating up water.
By Fig. 1, shown in Figure 2, the utility model is made up of burner hearth (1), cooking dish (2), plate type heat exchanger (3), ash bucket (4), moving grate (5), smoke flue (6), igniting heat exchange change-over switch (7), upper flue (9), lower flue (8).
In Fig. 1, when igniting heat exchange change-over switch (7) switches to the heat exchange state, the direction of arrow was discharged by chimney by burner hearth (1), upper flue (9), plate type heat exchanger (3), lower flue (8), change-over switch (7), smoke flue (6) shown in the high-temperature flue gas that the burner hearth fuel combustion produces was pressed successively, flue-gas temperature is reduced to below 120 ℃ after actual measurement is through the plate type heat exchanger heat exchange, and the thermal efficiency is greater than 80%.
In Fig. 2, igniting heat exchange change-over switch (7) when switching to fired state, flue gas flows in the direction of arrows, can not spill into indoor without plate type heat exchanger (7) flue gas when guaranteeing to light a fire.
