Description
Technical field
The utility model is related to a kind of heating furnace spout device that can realize second-time burning, belongs to thermal technology's heating furnace technology
Field.
Background technology
Mainly include coal gas burner, air burner using wide recuperative heater spout device at present and pacify respectively
Loaded on gas port and air port on heating furnace furnace wall, gas port is connected with coal gas burner, and air port burns with air
Mouth is connected；When heating furnace works, typically one coal gas one air of correspondence burns on burner hearth inner edge mixing side, becomes after having burnt
Burner hearth is then exhausted from into flue gas；Burning in recuperative heater burner hearth belongs to the mixed effect of diffusion combustion, i.e. coal gas, air
Influence efficiency of combustion, with the increase and the reduction using calorific value of gas of heating furnace output, the coal gas needed for single coal gas burner
Amount is increasing, while combustion air volume corresponding with coal gas is also increasing, two strands of larger amount of coal gas and air are in burner hearth
Meet, insufficient, reduction efficiency of combustion of burning can occur because of situations such as mixed effect difference, while combustion high temperature region Tai Ji
In, it is unfavorable for the uniformity of fire box temperature.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of heating furnace spray that can realize secondary mixed combustion
Combustion air can be divided into two strands by mouth device, this spout device, realize the secondary mixing combustion of coal gas, air in burner hearth
Burn, the uniformity of lifting gas combustion efficiency and fire box temperature.
Solving the technical scheme of above-mentioned technical problem is：
A kind of heating furnace spout device that can realize secondary mixed combustion, including coal gas burner, air burner and difference
Gas port and air port on heating furnace furnace wall are installed on, gas port is connected with coal gas burner, air port and air
Burner is connected, and its improvements is：Angle is acute angle between the center line and heating furnace furnace wall of the gas port；The air
Spout includes primary air spout and auxiliary air spout, the center line of primary air spout and the centerlines of gas port
It is acute angle, angle is acute angle between heating furnace furnace wall, and angle is between the center line and heating furnace furnace wall of auxiliary air spout
Right angle.
A kind of above-mentioned heating furnace spout device that can realize secondary mixed combustion, the center line of the gas port with
Angle is 10 °~80 ° between heating furnace furnace wall, between the center line and heating furnace furnace wall of primary air spout angle be 10 °~
80°。
A kind of above-mentioned heating furnace spout device that can realize secondary mixed combustion, the gas port and primary air
Beeline between spout is less than the beeline between gas port and auxiliary air spout.
Using heating furnace of the present utility model operationally, due to gas port, primary air spout and heating furnace furnace wall
Angle be 10 °~80 ° and primary air spout central line intersects with gas port center line, and gas port is to once empty
Beeline between gas blowout mouthful is less than the beeline between gas port and auxiliary air spout, so being sprayed by gas port
Enter the coal gas in burner hearth carries out mixed combustion with by the primary air in primary air spout penetrating burner hearth first, imperfect combustion
Coal gas continue with by auxiliary air spout spray into burner hearth in auxiliary air carry out mixed combustion, Gas Flow stock-traders' know-how crosses air stream
After stock flow-disturbing mixing twice, burning is reached fully, improve the effect of efficiency of combustion；Primary combustion and the initial of second-time burning meet
The position of mixing point, can be according to furnace width, by adjustment and the folder of gas port, primary air spout and heating furnace furnace wall
Angle is adjusted.
The beneficial effects of the utility model are：
The utility model increases auxiliary air spout on the outside of the primary air spout before original air burner, will be with coal
Gas mixes combustion-supporting air and is divided into two strands by one, increases disturbance mixed effect of the combustion air to coal gas, improves gas-fired
Efficiency；Meanwhile, the initial mixing position of primary combustion and second-time burning can be adjusted flexibly according to furnace width, make in burner hearth
Furnace temperature evenly, improves workpiece heat quality.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the enlarged drawing of part A in Fig. 1；
Marked in figure：Coal gas burner 1, air burner 2, gas port 3, primary air spout 4, auxiliary air spout 5,
Heating furnace furnace wall 6, burner hearth 7, primary combustion initial mixing point 8, second-time burning initial mixing point 9.
Specific embodiment
Fig. 1 and Fig. 2 show, a kind of heating furnace spout device that can realize secondary mixed combustion of the utility model, including
Coal gas burner 1, air burner 2, the gas port 3 being installed on heating furnace furnace wall 6 and it is installed on heating furnace furnace wall 6 once
Air port 4 and auxiliary air spout 5, gas port 3 are connected with coal gas burner 1, primary air spout 4 and auxiliary air spout
5 are connected with air burner 2 respectively, and the beeline between gas port 3 and primary air spout 4 is less than gas port 3 and two
Beeline between secondary air port 5；Angle is 10 °~80 ° sharp between the center line and heating furnace furnace wall 6 of gas port 3
