Description

A kind of normal-pressure boiler

The utility model relates to a kind of normal-pressure boiler.

Existing heating boiler is owing to the reason of body of heater internal structure design, the general chamber structure that adopts single flue, mode of heating mostly is the directly-fired kiln courage one time, tends to cause the calory burning utilization incomplete like this, the thermal efficiency is not high, thereby influences the performance of boiler heat supplying ability.

In order to overcome above-mentioned weak point, the purpose of this utility model is to provide a kind of high normal-pressure boiler of calory burning, heating efficiency that can make full use of fuel.

The technical solution of the utility model is: this normal-pressure boiler comprises body of heater, fire bars, fire door, furnace water jacket and inlet tube and outlet tube, its characteristics are that furnace water jacket is made up of the vertical heating tube around outer courage, middle courage, inner bag and the burner hearth, all leave passage of flame between each courage, the top of middle courage and the bottom of inner bag all have the plane tank, the plane tank has some vertical heating tubes, the bottom of heating tube is connected with annular water tank, and inner bag and middle courage, middle courage and outer courage communicate.

In order more effectively to utilize calory burning, above-mentioned inside of boiler is nested with and adds courage, communicates between the two courage chambeies; The outer courage inwall at burner hearth place is provided with heat absorbing sheet.

For the ease of the cleaning ashes, be provided with the deashing element in the described body of heater.

The utility model has been realized turning over fire twice by above design, by the heating for multiple times of vertical heating tube and the water courage more than three, thereby makes the burner hearth Btu utilization abundant, has improved the heating efficiency of boiler.The utility model can be used for the warming of small sizes such as family, shop.

Below in conjunction with accompanying drawing embodiment of the present utility model is done to describe in detail:

Fig. 1 is the cutaway view of the utility model embodiment one;

Fig. 2 is the perspective view of the utility model embodiment one;

Fig. 3 is the cutaway view of the utility model embodiment two;

Fig. 4 is the perspective view of the utility model embodiment two.

See figures.1.and.2, the utility model embodiment one comprises body of heater 1, fire bars 14, fire door 13, furnace water jacket and inlet tube and outlet tube, its characteristics are that furnace water jacket is made up of the vertical heating tube 10 around outer courage 5, middle courage 6, inner bag 7 and the burner hearth, form passage of flame between each courage, the top of middle courage 6 and the bottom of inner bag 7 have plane tank 2 and plane tank 9 respectively, plane tank 9 has some vertical heating tubes 10, the bottom of heating tube 10 is connected with annular water tank 12, and inner bag 7 and middle courage 6, middle courage 6 and outer courage 5 communicate.

In order more effectively to utilize calory burning, the outer courage inwall at above-mentioned boiler furnace place is provided with heat absorbing sheet 11, and inner bag 7 is with to add between courage 8, the two courage chambeies and communicates.

With reference to Fig. 1～Fig. 4, embodiment two and embodiment one are basic identical.Different is behind the middle courage 6 and inner bag 7 combinations with embodiment one, during installation sub-assembly integral body to be upside down in the outer courage 5.According to the order of passage of flame and current heating, courage has become inner bag in making, and inner bag has become middle courage.Passage of flame is by inwardly upset between outer courage and the inner bag.This design has been because of having strengthened the diameter and the area of the inner bag that can directly be heated, comparatively favourable to current.

With reference to Fig. 3 and Fig. 4, in embodiment two,, be provided with deashing element 16 in the described body of heater 1 for the ease of the cleaning ashes, it is to offer ash-falling hole in plane tank 9 centers, the ash-falling hole plug has been dialled got final product deashing, stops up to prevent the long-time flue that causes that uses.

See figures.1.and.2, normal-pressure boiler of the present utility model in use, just rotary head is descending to the plane tank 2 on middle courage 6 tops through inner bag 7 and the flame that adds courage 8 internal combustion, and is descending through the passage of flame between in inner bag 7 and the middle courage 6, walk to overturn again behind the inner bag plane tank 9 up.Enter chimney 3 by the passage of flame between middle courage 6 and the outer courage 5.Make by water inlet pipe 15 enter outer courage 5, from outer courage 5 enters courage 6, arrival outlet pipe 4 after therefrom courage 6 enters inner bag 7 and adds the current heating for multiple times of courage 8 again, send in the heating system.

By above design, realized turning over fire twice, by the heating for multiple times of vertical heating tube 10 and the water courage more than three, thereby make the burner hearth Btu utilization abundant, improved the heating efficiency of boiler.

See figures.1.and.2,, can utilize this stove to cook, be heating, the dual-purpose stove of cooking if the plane tank 2 on courage 6 tops in removing covers with courage 6 tops in the bell handle.
