Abstract

The utility model provides a coal, gas and oil boiler which comprises a boiler body. An inner container is arranged in the boiler body. A water cavity is formed between the inner container and the boiler body. A combustion chamber and a heat exchange chamber are formed in the inner container, the combustion chamber is arranged near the heat exchange chamber, two layers of fire grate pipes are arranged in the combustion chamber, pipe cavities of the fire grate pipes are communicated with the water cavity, the fire grate pipes in each layer are arranged at intervals, and the fire grate pipes divide the combustion chamber into a coal combustion chamber, a gas combustion chamber and an ash chamber. Three smoke strile-back chambers are arranged in the heat exchange chamber and communicated in sequence through a smoke heat exchange pipe, the rear ends of the smoke strile-back chambers are provided with smoke collection chambers and smoke outlets, and the gas combustion chamber is communicated with the smoke strile-back chambers. According to the coal, gas and oil boiler, combustion of coal and gas in the boiler are achieved in different chambers, coal combustion or gas combustion can be achieved independently and can also be achieved together, and multi-functional combustion of the boiler is achieved.

Description

A kind of coal, gas, oily three-purpose boiler

Technical field

The utility model relates to a kind of boiler, more particularly relates to a kind of coal, gas, oily three-purpose boiler.

Background technology

Under the large situation that is development trend with city large-scale centralized heat supply under the prerequisite day by day improving in environmental requirement standard, the boiler of no matter heating up water using at present or the boiler of heating, concentrated supply of heating in the city boiler, substantially be all coal-burning boiler, and in the higher big and medium-sized cities of environmental requirement, coal-burning boiler is again not allow to use, and all changes gas fired-boiler into, or oil burning boiler.Above-mentioned several boiler is all simple function, and coal-burning boiler can not fuel oil or combustion gas, and fuel oil and gas fired-boiler can not be coal-fired.User has often just bought coal-burning boiler, forbids again suddenly having burnt coal, by superseded boiler too unfortunate again, does not eliminate and can not use again, causes very large waste to user.

Summary of the invention

In order to overcome the deficiencies in the prior art, the utility model provides a kind of coal, gas, oily three-purpose boiler.

The utility model is achieved through the following technical solutions: a kind of coal, gas, oil three-purpose boiler, comprise body of heater, inner bag is set in body of heater, between inner bag and body of heater, form water cavity, combustion chamber and heat-exchanging chamber are set in inner bag, described combustion chamber is arranged on the side of heat-exchanging chamber, in described combustion chamber, be provided with two-layer furnace grate tube, the tube chamber of furnace grate tube communicates with described water cavity, arrange every layer of furnace grate tube space, combustion chamber is divided into coal-fired chamber by two-layer furnace grate tube, fuel chamber and cinder chamber, in described heat-exchanging chamber, be provided with three flue gas return combustion chambers, between three flue gas return combustion chambers, be communicated with successively by flue gas heat exchange tube, the rear end of flue gas return combustion chamber is provided with fume collecting chamber and exhaust opening, described fuel chamber communicates with flue gas return combustion chamber.

In such scheme, described furnace grate tube is obliquely installed.

In such scheme, the top of described heat-exchanging chamber arranges smoke pipe inspection opening, on smoke pipe inspection opening, upper cover is set.

Compared with prior art, its beneficial effect is for this coal, gas, oily three-purpose boiler:

1, the coal in this boiler and gas locellus burning, both can burn separately coal or burn gas, can merge again that to burn coal gentle simultaneously, realized boiler combustion multifunction.

2, furnace grate tube adopts tubular structure, and tube chamber communicates with body of heater water cavity, has improved the rate of heat exchange of boiler.

Accompanying drawing explanation

Accompanying drawing is the structural representation of the utility model coal, gas, oily three-purpose boiler;

In figure: 1. body of heater, 2. inner bag, 3. water inlet, 4. lower fire grating pipe, 5. ash hole, 6. bocca, 7. discloses burner, 8. upper fire-grating pipe, 9. fuel chamber, 10. coal-fired chamber, 11. coal filling holes, 12. water cavities, 13. delivery ports, 14. upper covers, 15. second flue gas return combustion chambers, 16. pressure relief openings, 17. exhaust openings, 18. fume collecting chamber, 19. flue gas heat exchange tubes, 20. the 3rd flue gas return combustion chambers, 21. first flue gas return combustion chambers, 22. flue gas heat exchange tubes, 23. cinder chamber, 24. smoke pipe inspection openings.

The specific embodiment

Below in conjunction with accompanying drawing and specific embodiment, the utility model coal, gas, oily three-purpose boiler are further described:

Accompanying drawing is the structural representation of the utility model coal, gas, oily three-purpose boiler.In figure, this coal, gas, oil three-purpose boiler, comprise body of heater 1, the interior inner bag 2 that arranges of body of heater 1, between inner bag 2 and body of heater 1, form water cavity 12, interior combustion chamber and the heat-exchanging chamber of arranging of inner bag 2, described combustion chamber is arranged on the side of heat-exchanging chamber, in combustion chamber, be provided with two-layer furnace grate tube, upper fire-grating pipe 8 and lower fire grating pipe 4, arrange every layer of furnace grate tube space, combustion chamber is divided into coal-fired chamber 10 by upper fire-grating pipe 8 and lower fire grating pipe 4, fuel chamber 9 and cinder chamber 23, the top of coal-fired chamber 10 arranges coal filling hole 11, side is provided with discloses burner 7, on the sidewall of fuel chamber 9, be provided with bocca 6, combustor by bocca 6 to jet flames in combustion chamber, on the sidewall of cinder chamber 23, be provided with ash hole 5, lime-ash after burning thus mouth is drawn out.In heat-exchanging chamber, be provided with three flue gas return combustion chambers, respectively the first flue gas return combustion chamber 21, the second flue gas return combustion chamber 15 and the 3rd flue gas return combustion chamber 20, between the first flue gas return combustion chamber 21 and the second flue gas return combustion chamber 15, be connected by flue gas heat exchange tube 22, between the second flue gas return combustion chamber 15 and the 3rd flue gas return combustion chamber 20, be connected by flue gas heat exchange tube 19, the rear end of flue gas return combustion chamber is provided with fume collecting chamber 18 and exhaust opening 17; Fuel chamber 9 communicates with the first flue gas return combustion chamber 21.Be respectively arranged with delivery port 13 and pressure relief opening 16 in the upper side of heat-exchanging chamber.The top of heat-exchanging chamber arranges smoke pipe inspection opening 24, is used for detecting and maintenance flue gas heat exchange tube, and upper cover 14 is set on smoke pipe inspection opening 24.Be provided with water inlet 3 in the bottom of water cavity 12.
