Abstract

The utility model provides a direct-combustion gas-fired boiler. The direct-combustion gas-fired boiler comprises a boiler body, an inner container is arranged in the boiler body, a combustion chamber is arranged on the lower portion inside the inner container, a smoke collecting chamber is arranged on the upper portion inside the inner container, a plurality of smoke pipes are arranged between the combustion chamber and the smoke collecting chamber and spaced mutually, a water cavity is formed between the smoke pipes and the inner container, an outer cover is arranged outside the boiler body, and a heat preservation layer is arranged between the boiler body and the outer cover; a pipy boiler disc is arranged in the combustion chamber and provided with a plurality of fuel gas openings. The boiler is simple in structure, low in manufacturing cost and very convenient to use.

Description

A kind of direct combustion gas fired-boiler

Technical field

The utility model relates to a kind of boiler, more particularly relates to a kind of direct combustion gas fired-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.For reducing the pollution of the environment that we are depended on for existence, for reducing or eliminating haze weather, in the production of boiler, will firmly ban coal-burning boiler.

Summary of the invention

In order to overcome the deficiencies in the prior art, the utility model provides a kind of oligosaprobic direct combustion gas fired-boiler.

The utility model is achieved through the following technical solutions: a kind of direct combustion gas fired-boiler, comprise body of heater, in body of heater, be provided with inner bag, below, inner bag inside arranges combustion chamber, and inner bag inner and upper fume collecting chamber, arranges multiple fume pipes between described combustion chamber and fume collecting chamber, space between each fume pipe, between fume pipe and inner bag, form water cavity, body of heater outer setting has outer cover, between body of heater and outer cover, is provided with heat-insulation layer; In described combustion chamber, be provided with tubulose stone or metal plate for standing a stove on as a precaution against fire, multiple gas port are set on tubulose stone or metal plate for standing a stove on as a precaution against fire.

In such scheme, the dish type coiling in combustion chamber of described tubulose stone or metal plate for standing a stove on as a precaution against fire.

In such scheme, described fume collecting chamber is set to taper, up-small and down-big.

Compared with prior art, its beneficial effect is this direct combustion gas fired-boiler:

1, the bags of this boiler is large, and the carbon deposit forming when burning is few, and the degree of filling of flue gas is good, without dead angle;

Brief description of the drawings

Fig. 1 is the structural representation of the utility model direct combustion gas fired-boiler;

Fig. 2 is the A-A cutaway view in Fig. 1.

In figure: 1. outer cover, 2. tubulose stone or metal plate for standing a stove on as a precaution against fire, 3. heat-insulation layer, 4. body of heater, 5. water cavity, 6. gas port, 7. combustion chamber, 8. fume pipe, 9. fume collecting chamber, 10. exhaust opening, 11. inner bags.

Detailed description of the invention

Below in conjunction with accompanying drawing and specific embodiment, the utility model direct combustion gas fired-boiler is further described:

Fig. 1 is the structural representation of the utility model direct combustion gas fired-boiler, and Fig. 2 is the A-A cutaway view in Fig. 1.In figure, this direct combustion gas fired-boiler, comprises body of heater 4, in body of heater 4, be provided with inner bag 11, the inner below of inner bag 11 arranges combustion chamber 7, inner bag 11 inner and upper fume collecting chamber 9, and the top of fume collecting chamber 9 arranges exhaust opening 10, fume collecting chamber 9 is set to up-small and down-big taper, multiple fume pipes 8 are set between combustion chamber 7 and fume collecting chamber 9, and space between each fume pipe 8, forms water cavity 5 between fume pipe 8 and inner bag 11, body of heater 4 outer setting have outer cover 1, between body of heater 4 and outer cover 1, are provided with heat-insulation layer 3; In combustion chamber 7, be provided with tubulose stone or metal plate for standing a stove on as a precaution against fire 2, multiple gas port 6 are set on tubulose stone or metal plate for standing a stove on as a precaution against fire 2, tubulose stone or metal plate for standing a stove on as a precaution against fire 2 is dish type coiling in combustion chamber 7.

This boiler structure is very simple, and as natural gas range, by after natural gas igniting, the gas of burning, by the water heating in water cavity 5, by the further heat exchange of fume pipe 8 and water, improves the efficiency of heating surface of water in water cavity 5.This boiler structure is simple, and cost is low, very easy to use.

The above, it is only preferred embodiment of the present utility model, not the utility model is done to any pro forma restriction, although the utility model discloses as above with preferred embodiment, but not in order to limit the utility model, any those skilled in the art, do not departing within the scope of technical solutions of the utility model, when can utilizing the method for above-mentioned announcement and technology contents to make a little change or being modified to the equivalent embodiment of equivalent variations, in every case be the content that does not depart from technical solutions of the utility model, any simple modification of above embodiment being done according to technical spirit of the present utility model, equivalent variations and modification, still belong in the scope of technical solutions of the utility model.
