Description

A kind of domestic efficient heating stove

Technical field

The utility model relates to a kind of domestic efficient heating stove.

Background technology

Flue gas after the heating stove burning is discharged through flue, but contain a large amount of waste heats in the flue gas, can not cause thermal waste if do not recycle, make the thermal efficiency of heating stove not high, the general flue of Domestic heating stove that uses at present is positioned at the top of burner hearth, waste heat in the flue gas is got rid of without just reclaiming, carry out heat recovery although the flue that has is provided with the jacket water (J.W.) cover, recovering effect is unsatisfactory, and because flue is positioned at the top of body of heater, the body of heater volume is increased, be unfavorable for transportation and installation.

The utility model content

The technical problems to be solved in the utility model provides a kind of domestic efficient heating stove, and it has, and volume is little, the thermal efficiency is high, make things convenient for the characteristics such as production and transport and installation.

For solving the problems of the technologies described above, technical solution adopted in the utility model is: it comprise burner hearth, upper furnace the second-time burning mouth, be positioned at outside secondary air distribution outlet and the furnace water jacket that is connected with the second-time burning mouth of body of heater, it also comprises the smoke gas afterheat heat exchanger that is positioned at body of heater inside and is connected with lower furnace portion in addition, smoke gas afterheat heat exchanger is provided with floss hole by the dividing wall type heat exchanger that the circulating water cavity that is connected with furnace water jacket and smoke chamber form on smoke gas afterheat heat exchanger top.

The utility model further improves and is: it is cuboid, burner hearth and smoke chamber are separated by hearth wall, and the bottom is connected, circulating water cavity is made of outside water cavity and inner water cavity, outside water cavity is furnace water jacket, and inner water cavity is to be positioned at the heat exchanger tube that the two ends of smoke chamber are connected with furnace water jacket; Burner hearth and smoke chamber connected entrance are provided with the cooking heating switch boards; Floss hole is two, is respectively cleaning door and road a heatable brick bed mouth, and cleaning door is positioned at directly over the smoke chamber and is provided with seal cover, and road a heatable brick bed mouth is positioned at the side relative with burner hearth, smoke chamber top, is provided with level or slightly acclivitous exhaust gases passes at road a heatable brick bed mouth; The volume of smoke chamber is the 1/3-2/3 of combustion space.

The beneficial effect that adopts technique scheme to produce is: it is provided with and is positioned at the inner smoke gas afterheat heat exchanger that is connected with lower furnace portion of body of heater, the dividing wall type heat exchanger that smoke gas afterheat heat exchanger is comprised of the circulating water cavity that is connected with furnace water jacket and smoke chamber, this shows that its heat exchange efficiency is higher than the heat exchange efficiency of used flue chuck water jacket far away, the design of breaking the normal procedure of this heating stove, flue gas enters efficient dividing wall type heat exchanger by burner hearth bottom and carries out heat recovery and utilization, its waste heat is fully cemented out, reduce the heat that heating stove is discharged by flue gas, heating stove improves the thermal efficiency needs two conditions: 1, make combustible fully burn (chemical reaction is abundant, and by second-time burning the materials such as CO being burnt again produces heat energy).2, reduce thermal loss (such as the heat loss of flue and furnace wall) as far as possible.This heating stove is provided with second-time burning mouth and secondary air distribution outlet, can carry out second-time burning, makes burning more abundant, reduces simultaneously the discharging of dusty gas; Reduce thermal loss by furnace water jacket and smoke gas afterheat heat exchanger, therefore greatly improved the thermal efficiency of heating stove, reduced simultaneously the body of heater volume, be convenient to production and transport and installation; Burner hearth and smoke chamber connected entrance are provided with the cooking heating switch boards.Switch handle by cooking heating flue gas flow direction is switched, conveniently utilize stockhole to cook and heat up water.

In the accompanying drawings: 1, burner hearth; 2, second-time burning mouth; 3, secondary air distribution outlet; 4, furnace water jacket; 5, smoke chamber; 6, heat exchanger tube; 7, cooking heating switch boards; 8, exhaust gases passes; 9, cleaning door; 10, cooking heating switches handle; 11, fire grate; 12, fire grate handle; 13, coal feed point; 14, water inlet; 15, delivery port; 16, stockhole.

The specific embodiment

By the embodiment shown in Fig. 1-3 as can be known, it comprise burner hearth 1, burner hearth 1 top second-time burning mouth 2, be positioned at outside secondary air distribution outlet 3 and the furnace water jacket 4 that is connected with second-time burning mouth 2 of body of heater, it also comprises the smoke gas afterheat heat exchanger that is positioned at body of heater inside and is connected with burner hearth 1 bottom in addition, smoke gas afterheat heat exchanger is provided with floss hole by the dividing wall type heat exchanger that the circulating water cavity that is connected with furnace water jacket 4 and smoke chamber 5 form on smoke gas afterheat heat exchanger top; It is cuboid, and burner hearth 1 and smoke chamber 5 are separated by hearth wall, and circulating water cavity is made of outside water cavity and inner water cavity, and outside water cavity is furnace water jacket 4, and inner water cavity is to be positioned at the heat exchanger tube 6 that the two ends of smoke chamber 5 are connected with furnace water jacket 4; Burner hearth 1 and smoke chamber 5 connected entrances are provided with cooking heating switch boards 7; Floss hole is two, is respectively cleaning door 9 and road a heatable brick bed mouth, and cleaning door 9 is positioned at directly over the smoke chamber 5 and is provided with seal cover, and road a heatable brick bed mouth is positioned at the relative side of smoke chamber 5 tops and burner hearth 1, is provided with level or slightly acclivitous exhaust gases passes 8 at road a heatable brick bed mouth; The volume of smoke chamber 5 is the 1/3-2/3 of burner hearth 1 volume.

The course of work when utilizing these family expenses high efficient heating furnace to warm oneself and cook is as follows:

During heating, the cooking heating switch boards is switched handle by cooking heating to be opened, flue gas is fully replaced its waste heat in the heating circulating water by the higher smoke gas afterheat heat exchanger of heat exchange efficiency, reduce the heat that heating stove is discharged by flue gas, improved the thermal efficiency of heating stove, flue gas enters heated kang by exhaust gases passes and heats to heated kang, enter atmosphere by the chimney that is connected with heated kang again, if the flue gas house dust is too many, can be cleared up by cleaning door, if flue gas can be with the exhaust gases passes shutoff without heated kang, flue gas can enter atmosphere through chimney by cleaning door.

When cooking or heat up water, the cooking heating switch boards is switched handle by cooking heating close, flue gas is discharged by stockhole, the stockhole flame of can emerging, temperature is very high, can cook or heat up water.
