The utility model has the advantages of novel structure, coal saving, high heat efficiency and faster temperature rising. The utility model can make a plurality of groups of radiators for heating rooms, and meanwhile, the rice cooking can not be affected.

Description

Stove with heat exchanger

The utility model relates to adopt solid-fuelled heating to cook domestic burners that hot water uses, is a kind of Stove with heat exchanger.

At present, the cook domestic burners of hot water of common heating, shortcoming such as it is low all to exist the thermal efficiency, and coal consumption is higher, and thermal loss is big, and hot water circuit is not ideal enough, and it is slow to heat up, and it is insufficient to burn.

The purpose of this utility model is to overcome the deficiency of prior art and designs the Stove with heat exchanger that a kind of not only coal consumption is low but also the thermal efficiency is high.

The purpose of this utility model realizes by following measure: this Stove with heat exchanger comprises burner hearth, fire bars, flue and intercalated water sleeve and outlet pipe and return pipe, the burner hearth intercalated water sleeve is arranged between the internal protecting wall of its burner hearth and the outer furnace wall, one the ear shape pipe of being no less than that communicates with the burner hearth intercalated water sleeve is arranged on the internal protecting wall; The outlet flue of burner hearth is connected to the return air inner flue, and the return air inner flue has the inner flue intercalated water sleeve outward; The inner flue intercalated water sleeve communicates with the burner hearth intercalated water sleeve and is one; External flue has the external flue intercalated water sleeve outward; The external flue intercalated water sleeve communicates with inner flue intercalated water sleeve or burner hearth intercalated water sleeve and is one; Eight ear shape pipes that communicate with the burner hearth intercalated water sleeve are arranged on the internal protecting wall.

Accompanying drawing 1 is the three-dimensional profile schematic diagram of the utility model most preferred embodiment;

Accompanying drawing 2 is the stereochemical structure partial sectional view of the utility model most preferred embodiment;

Accompanying drawing 3 is the structure cutaway view of the utility model most preferred embodiment burner hearth intercalated water sleeve and ear shape pipe;

Accompanying drawing 4 is that the A-A of accompanying drawing 3 is to the structure cutaway view;

Accompanying drawing 5 is the structure sectional plan view of the utility model most preferred embodiment;

Accompanying drawing 6 is that the B-B of accompanying drawing 5 is to the structure cutaway view;

Coding in the accompanying drawing is respectively: 1 is external flue, and 2 is top board, and 3 is the external flue intercalated water sleeve, 4 is bell, and 5 is outer furnace wall, and 6 is the air intake fire door, 7 is the return air inner flue, and 8 is internal protecting wall, and 9 are ear shape pipe, 10 is the burner hearth intercalated water sleeve, and 11 is fire bars, and 12 is burner hearth, 13 is the inner flue intercalated water sleeve, and 14 is the external flue intercalated water sleeve, and 15 is flue, 16 is intercalated water sleeve, and 17 is outlet pipe, and 18 is return pipe.

Below in conjunction with most preferred embodiment the utility model is further described:

Shown in attached Fig. 1 and 2, this most preferred embodiment comprises burner hearth 12, fire bars 11, flue 15 and intercalated water sleeve 16 and outlet pipe 17 and return pipe 18, between the internal protecting wall 8 of its burner hearth 12 and the outer furnace wall 5 burner hearth intercalated water sleeve 10 is arranged, eight ear shape pipes 9 that communicate with burner hearth intercalated water sleeve 10 are arranged on the internal protecting wall 8; In order to make full use of heat, the outlet flue of burner hearth 12 is connected to return air inner flue 7, and inner flue intercalated water sleeve 13 is arranged outside the return air inner flue 7, preferably inner flue intercalated water sleeve 13 communicates with burner hearth intercalated water sleeve 10 and is one, simultaneously, external flue intercalated water sleeve 14 is arranged outside the external flue 1, and preferably external flue intercalated water sleeve 14 communicates with inner flue intercalated water sleeve 13 or burner hearth intercalated water sleeve 10 and is one.

Owing to the ear shape pipe 9 that communicates with burner hearth intercalated water sleeve 10 is arranged on the internal protecting wall 8, thereby has increased heating surface area, and, accelerated the circulation rate of water in the burner hearth intercalated water sleeve 10, thereby improved the thermal efficiency by ear shape pipe 9.In order to make full use of flue gas heat, flue 15 is made of return air inner flue 7 and external flue 1, and inner flue intercalated water sleeve 13 arranged outside return air inner flue 7, external flue intercalated water sleeve 14 is arranged outside external flue 1, through preliminary test, the exit gas temperature of external flue 1 is generally 68 ℃, than the reduction greatly of other domestic burners.

General civil boiler commonly used, the many groups of band radiator is for 80 square metres of room heatings, and year coal consumption needs about 4.5 tons, and room temperature and not really high; And,,, only needed 2.5 tons of coals in 1 year to being equal to or greater than 80 square metres of rooms heating by the radiator of outlet pipe 17 and the same quantity of return pipe 18 drives with this most preferred embodiment Stove with heat exchanger, just can satisfy the demand, and room temperature can remain on more than 18 ℃; Therefore the utility model is not only economized the coal but also the thermal efficiency.

The utility model novel structure, easy to use uses this Stove with heat exchanger not only can the fuel saving coal, and the thermal efficiency is higher, and it is very fast to heat up, do not influence cook in, can be with many group radiators is the room heat supply.
