Abstract
The utility model is a kind of liquid fuel burner hearth, and the pot edge of burner hearth is intervally distributed with air discharge duct, and its main points are, the inclined-plane of air discharge duct and the angle of horizontal plane are 50-70 °, and the difference in height on top, pot edge and air discharge duct top is 4-12mm.The utility model is changed little to prior art, strengthens the angle of air discharge duct inclined-plane and horizontal plane, more points to the bottom of a pan to the guiding of tail gas, make the heat exchange of the bottom of a pan and tail gas more abundant, make combustion gas long for the residence time in burner hearth simultaneously, burn more abundant, efficiency of combustion is high, economize energy.
Description
Technical field
The utility model belongs to burner hearth, especially belongs to liquid fuel gasification furnace thorax.
Background technology
Existing liquid fuel mainly alcohol radical liquid fuel, its burner hearth is as Fig. 1, shown in 2, the firehole 16 installing burner 2 is had in the middle of bottom burner hearth 1, the internal diameter of firehole 16 is greater than the external diameter of burner, gap is wherein as the inlet channel of burning, in order to utilize flame temperature better, the distance of the bottom of a pan and burner is shorter, burnt gas is discharged by the air discharge duct 12 on the pot edge 11 of burner hearth, the effect of support pot is played in pot edge 11, so air discharge duct 12 is distributed on pot edge 11, usually just air discharge duct 12 is not established on the position of cook, to prevent waste gas, the harm such as scald are caused to it, the length on air discharge duct 12 inclined-plane is 50mm, the degree of depth is about 30mm, the angle of air discharge duct 12 inclined-plane and horizontal plane is about 35 °, the difference in height on top, pot edge and air discharge duct 12 top is about 20mm, because exhaust cross section is large, exhaust resistance is little, in burner hearth, unburned combustion gas thoroughly is easily taken out of by flue gas, and make burning insufficient, efficiency of combustion is low.And existing burner 2 is fixed in burner hearth, the combustion high temperature in burner hearth also have impact on the service life of burner 2.
Summary of the invention
The utility model object is to overcome above-mentioned defect, provides a kind of and can make the liquid fuel burner hearth that fuel gas buring is more abundant, improve efficiency of combustion.
The utility model is a kind of liquid fuel burner hearth, and the pot edge of burner hearth is intervally distributed with air discharge duct, and its main points are, the inclined-plane of air discharge duct and the angle of horizontal plane are 50-70 °.
The utility model improves on the basis of existing liquid fuel burner hearth, strengthen the angle of air discharge duct inclined-plane and horizontal plane, that is the bottom surface of air discharge duct inclined-plane and pot is more close, it points to the bottom of a pan more to the guiding of tail gas, make the heat exchange of the bottom of a pan and tail gas more abundant, be conducive to improving efficiency of combustion.
Consider and be designed to preferably: the inclined-plane of air discharge duct and the angle of horizontal plane are 50-60 °.
The difference in height on top, pot edge and air discharge duct top is 4-12mm.Reduce the degree of depth of air discharge duct, reduce exhaust cross section, make combustion gas long for the residence time in burner hearth, burning is more abundant, and efficiency of combustion is high.
The difference in height on top, pot edge and air discharge duct top is 8-10mm.
Air admission hole is had in the below of burner hearth.Increase air admission hole, for burning provides more oxygen, the chivalrous burning of energy is more abundant.
There are three centres being evenly arranged in bottom surface inwall and firehole in arc-shaped air admission hole.
The outer of air admission hole and the distance of bottom surface inwall are 2-5mm.
Burner is fixed on the below of burner hearth, and the upper surface of burner and the inner surface of burner hearth are put down.Such burner is not subject to the impact of burner hearth high temperature, long service life.
At interior thorax built with heat-preservation cotton.Can prevent heat from spreading out of in burner hearth and affecting environment temperature, improve the utilization rate of heat energy.
Burner is fixed on the below of burner hearth, and the upper surface of burner and the inner surface of heat-preservation cotton are put down.
The utility model is changed little to prior art, strengthens the angle of air discharge duct inclined-plane and horizontal plane, more points to the bottom of a pan to the guiding of tail gas, make the heat exchange of the bottom of a pan and tail gas more abundant, make combustion gas long for the residence time in burner hearth simultaneously, burn more abundant, efficiency of combustion is high, economize energy.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail, professional and technical personnel can be made more to understand the utility model.
Embodiment 1, as shown in Figure 3,4, a kind of liquid fuel burner hearth, it improves on the basis of existing liquid fuel burner hearth, reduces the degree of depth of air discharge duct, reduces exhaust cross section, specifically: the internal diameter of burner hearth 1 is 38cm, its pot edge 11 is intervally distributed with air discharge duct 12, and the difference in height on top, pot edge and air discharge duct 12 top is 4-12mm, and the inclined-plane of air discharge duct 12 and the angle of horizontal plane are 50-70 °.Better design is: the difference in height on top, pot edge and air discharge duct 12 top is 8-10mm, and the angle of air discharge duct 12 inclined-plane and horizontal plane is be 8mm in 50-60 °, figure, 60 °.There is air admission hole 13 in the bottom surface of burner hearth, have three centres being evenly arranged in bottom surface inwall 17 and firehole 16 in arc-shaped air admission hole 13, or the distance of the outer of air admission hole 13 and bottom surface inwall 17 is 2-5mm.Burner 2 is fixed on the below of burner hearth, and the inner surface of the upper surface of burner 2 and burner hearth (1) is put down.It is same as the prior art that all the other do not state part.
