Abstract
The utility model relates to a civilian clean moulded coal heating stove secondary air distribution structure, including air door, secondary air distribution port, be equipped with the secondary air distribution storehouse of embedded installation on the furnace body lateral wall, the outside in secondary air distribution storehouse is equipped with the air door, opens the secondary air distribution port that has the echelonment on the inside wall in secondary air distribution storehouse, the ladder shape and the flame burning walking form and the high matching in secondary air distribution port. The utility model discloses a secondary air distribution storehouse sets up the secondary air distribution mouth of echelonment, can satisfy the required reasonable amount of wind of burning according to the heating power air damper aperture of heating stove, makes the combustible gas complete combustion that the high temperature produced, does not make the required air of burning excessive again, reduces the heat loss of discharging fume.
Description
Technical Field
The utility model relates to a civil clean coal heating furnace, in particular to a secondary air distribution structure of the civil clean coal heating furnace.
Background
The existing clean coal heating furnace is generally provided with a primary air supply structure at one side or two sides of an air chamber at the bottom of a fire grate, a secondary distribution structure is arranged at the side part of a furnace body corresponding to a hearth, and the traditional secondary distribution structure is only an air inlet with a valve, so that the traditional secondary distribution structure can meet the combustion of clean coal, but cannot be reasonably matched with the air quantity required in the combustion process, the energy waste is caused, the fuel cannot be completely combusted to generate carbon monoxide, and the gas poisoning is caused.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to provide a civilian clean moulded coal heating stove secondary air distribution structure, guarantee the complete burning of fuel promptly, do not cause the heat loss increase of discharging fume again.
The utility model provides a technical scheme that its technical problem adopted is:
a secondary air distribution structure of a civil clean coal heating furnace comprises an air door and a secondary air distribution port, wherein an embedded secondary air distribution bin is arranged on the side wall of a furnace body, the air door is arranged on the outer side of the secondary air distribution bin, a stepped secondary air distribution port is formed in the inner side wall of the secondary air distribution bin, and the stepped shape of the secondary air distribution port is matched with the flame combustion walking shape and height.
When the heating is normal, the opening degree of the air door is adjusted according to the combustion condition, so that the molded coal is completely combusted; when the fire is closed, the air door is closed to prevent smoke.
Adopt above-mentioned technical scheme the utility model discloses, compare with prior art, beneficial effect is:
the secondary air distribution bin is provided with the stepped secondary air distribution port, so that the opening degree of the air door can be adjusted according to the heat supply power of the heating furnace, the reasonable air quantity required by combustion is met, the combustible gas generated at high temperature is completely combusted, the excessive air required by combustion is avoided, and the heat loss of smoke exhaust is reduced.
Further, the utility model discloses preferred scheme is:
the secondary air distribution bin is arranged at the position 40mm below the furnace cover, and the secondary air distribution opening corresponds to the outlet of the hearth.
