Abstract
The utility model relates to a coal-combustion supporting device which comprises a combustion supporter, air inlet pipes and a blower fan, wherein a three-way pipe joint arranged on the lower end of an upper air inlet pipe is connected with the blower fan and a lower air inlet pipe, the upper end of the upper air inlet pipe, namely, the upper side of a furnace grill is connected with the combustion supporter which forms a cylindrical shape, the lower part of the combustion supporter is symmetrically and orderly provided with at least two rows of small air spraying holes and at least a row of large air spraying holes from bottom to top according to an axial direction in lines, and the lower air inlet pipe extends to a furnace ash chamber. The utility model has the advantages of fuel saving and convenient use, and reduces environmental pollution caused by smoke.
Description
Technical field
The utility model relates to a kind of fuel savings, protection environmental area, particularly relates to a kind of coal-fired combustion-supporting device.
Background technology
The fuel of extensive use mainly is coal in China's people's lives at present, the stove and accessory of existing various ways, because the contact area of fuel and air is little, the oxygen of supply is inadequate, and it is insufficient that coal burns, and cause very big waste and contaminated environment.There is a kind of fire grate to be provided with the stove and accessory of combustion-supporting, though can increase the contact area of fuel and air when using this stove and accessory just to begin to light a fire, and the combustion rate of increase coal, but ashes will stop up the air vent of combustion-supporting after a while, and can not normally bring into play the effect of combustion-supporting.
Summary of the invention
The purpose of this utility model is to remedy the deficiencies in the prior art, for people provide a kind of fuel savings, reduces environmental pollution, coal-fired combustion-supporting device easy to use.
The purpose of this utility model is achieved through the following technical solutions.
Coal-fired combustion-supporting device of the present utility model, comprise combustion-supporting, blast pipe, air blast, wherein the tee pipe coupling that is provided with of the lower end of upper blast pipe is connected with air blast and lower blast pipe, the upper end of upper blast pipe is that the upside of fire grate is connected with combustion-supporting, combustion-supporting is cylindrical, the bottom of described combustion-supporting is by the axis direction symmetry little fumaroles and the big fumarole of delegation at least of embarking on journey successively and being arranged with at least two row from bottom to top, and lower blast pipe stretches to the ashes thorax.
The utility model has the advantages that the air inflow that strengthens in the burner hearth, supply with oxygen abundance, even, make full combustion of fuel, fuel savings reduces the environmental pollution that flue dust causes.
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the A-A cutaway view of Fig. 1.
The specific embodiment
As Fig. 1, shown in Figure 2, coal-fired combustion-supporting device of the present utility model includes combustion-supporting, blast pipe, air blast, wherein the tee pipe coupling 9 that is provided with of the lower end of upper blast pipe 2 is connected with air blast 3 and lower blast pipe 7, the upper end of upper blast pipe 2 is that upside 20～30Cm place of fire grate 4 is connected with cylindrical shape combustion-supporting 1, and the axis direction of this combustion-supporting 1 is consistent with the floss hole direction, the bottom of described combustion-supporting 1 is by the axis direction symmetry little fumaroles 6 and the big fumarole 5 of delegation at least of embarking on journey successively and being arranged with at least two row from bottom to top, the pore size of this big fumarole 5 is 3.5mm～4.5mm, the pore size of little fumarole 6 is 1.5mm～2.5mm, little fumaroles 6 setting of staggering each other of described at least two row, and adjacent and not with the distance between the little fumarole in the delegation with adjacent and equating promptly to be 1Cm with the distance between the little fumarole in the delegation, thereby guaranteed the air inflow in the burner hearth, increase the contact area of fuel and air, the oxygen abundance of supplying with, evenly, make full combustion of fuel; Because described combustion-supporting 1 is arranged on the upside of fire grate 4, lower blast pipe 7 is arranged in the downside ashes thorax of fire grate 4, so even the ashes that produce after burning a period of time have stopped up lower blast pipe 7, the combustion-supporting 1 that is arranged on fire grate 4 upsides can not stop up, be that cylindrical shape combustion-supporting 1 still can normally be brought into play combustion-supporting effect, reach fuel savings, the purpose of the environmental pollution that the minimizing flue dust causes.
Described three blast connections 9 are provided with air control valve 8, can regulate the air inflow of upper blast pipe and lower blast pipe arbitrarily by this air control valve 8.
