Abstract
The invention provides a flame bridge structure of a furnace pipe and an air inlet ring. The flame bridge structure comprises the furnace pipe and the air inlet ring matched with the furnace pipe. The air inlet ring is in the shape of a frustum, and an opening of the air inlet ring faces downward. A circle of equal-radian protrusion structure is arranged on the inner side face of the air inlet ring and provided with air inlet holes evenly arranged at intervals. Ventilation holes are formed in the side wall of the top end of the furnace pipe. The protrusion structure is in an inner inclination state, and is attached to the side wall of the upper portion of the furnace pipe. The ventilation holes correspond to the air inlet holes in position in a one-to-one manner, and each air inlet hole is communicated with the corresponding ventilation hole. The flame bridge structure is arranged between the air inlet ring and the furnace pipe under the condition that an original furnace pipe structure is not changed, secondary ventilation holes are formed, and the combustion efficiency can be effectively improved.
Description
Technical field
The present invention relates to the grate structure of a kind of flue and air inlet ring.
Background technology
General existing biomass combustion furnace is all directly be placed in above flue by air inlet ring, air inlet ring is arranged bracing frame and can support boiler and burn.But because the flue of direct firing biomass fuel does not exist secondary air inlet, often only once ventilate at the ventilating opening of bottom, so the efficiency of combustion of biomass stove is not very high, a large amount of unburned fuel gas totally is all there is in the tail gas of final burning, can not save burning on the one hand and play maximum combustion efficiency, these imperfect combustion gases may contaminated air on the other hand.And existing secondary air is all generally change flue tube structure, form complicated version, this can significant increase cost and very inapplicable for common biomass combustion furnace.
Summary of the invention
The present invention proposes the grate structure of a kind of flue and air inlet ring, not changing in original flue tube structure situation, grate structure is set between air inlet ring and flue, form twice aeration hole, effectively can increase efficiency of combustion.
The present invention realizes particular by following technical scheme:
The grate structure of a kind of flue and air inlet ring, comprise the air inlet ring that flue and flue coordinate, described air inlet ring is frustum shape and opening down, and described air inlet ring medial surface is provided with the bulge-structure of the radians such as a circle, and described bulge-structure is provided with the fresh air inlet that uniform intervals is arranged; The sidewall on described flue top is provided with air vent, and described bulge-structure is tilted state and the sidewall on laminating flue top, and the position of described air vent is with the position one_to_one corresponding of described fresh air inlet and each fresh air inlet is communicated with corresponding air vent.
Further, described flue top is taper type, and upper end inside opening area is less than or equal to lower end inside opening area.
The beneficial effect that the present invention produces is: the present invention, not changing in original flue tube structure situation, arranges grate structure between air inlet ring and flue, forms twice aeration hole, effectively can increase efficiency of combustion.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is structural representation of the present invention;
Fig. 2 is boss structural section schematic diagram in the present invention.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
As shown in Figure 1, 2, the grate structure of a kind of flue and air inlet ring, comprise the air inlet ring 2 that flue 1 and flue coordinate, described air inlet ring 2 is opening down in frustum shape, described air inlet ring 2 medial surface is provided with the bulge-structure 3 of the radians such as a circle, and described bulge-structure 3 is provided with the fresh air inlet 5 that uniform intervals is arranged; The sidewall on described flue 1 top is provided with air vent 4, and described bulge-structure 3 is tilted state and the sidewall on laminating flue 1 top, and the position of described air vent 4 is with the position one_to_one corresponding of described fresh air inlet 5 and each fresh air inlet is communicated with corresponding air vent.
In the present embodiment, flue top is taper type, and upper end inside opening area is less than or equal to lower end inside opening area, ensures that inner combustion-gas flow flows in the top of flue in gathering shape.Be communicated with because the position of air vent 4 is formed with the position one_to_one corresponding of described fresh air inlet 5, when high-temperature gas due to inside is circulated to flue top, extraneous pressure is higher than the pressure in stove, and thus outside air enters into air vent 4 entering into stove inner top from fresh air inlet 5 and to contact with gas and form second-time burning.Owing to not changing the structure of flue in the present invention, just carry out coordinating, improving at air inlet ring and flue top, saved cost, and easily changed.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
Claims (2)
1. the grate structure of a flue and air inlet ring, comprise the air inlet ring that flue and flue coordinate, it is characterized in that, described air inlet ring is frustum shape and opening down, described air inlet ring medial surface is provided with the bulge-structure of the radians such as a circle, and described bulge-structure is provided with the fresh air inlet that uniform intervals is arranged; The sidewall on described flue top is provided with air vent, and described bulge-structure is tilted state and the sidewall on laminating flue top, and the position of described air vent is with the position one_to_one corresponding of described fresh air inlet and each fresh air inlet is communicated with corresponding air vent.
2. the grate structure of flue as claimed in claim 1 and air inlet ring, it is characterized in that, described flue top is taper type, and upper end inside opening area is less than or equal to lower end inside opening area.
