The coke oven can be heated by feeding gas through a regulating and exchanging plug on a coke oven gas main pipe, then feeding air through an air gas shutter of the blast furnace gas, and feeding the air into the combustion chamber through a chute and a vertical fire pipeline for combustion, and can also be heated by feeding air and the blast furnace gas through the air gas shutter respectively to realize the combustion heating in the combustion chamber. If the chute through which the blast furnace gas or air is taken is burnt or blocked, the air or gas cannot be supplied normally. When the chute is blocked, the fire hole can be drilled through by a drill rod at the top of the furnace, but the drill rod cannot be drilled through completely, the diameter of the drill rod is phi 36mm, because the chute is made of high-temperature resistant silica bricks, and holes drilled through the drill rod when the chute is burned out are far larger than phi 36 mm.

Therefore, the coke oven heating system provided by the embodiment adds the air supply system on the fire erecting pipeline, so that the sufficient supply of air can be ensured under the condition that the chute is damaged, and the temperature required by normal production is met.

The coke oven gas exchange cock 130 is provided with a carbon removal hole 131, and the carbon removal hole 131 mainly functions to remove tar and graphite in the brick gas channel and prevent the graphite and tar from blocking the brick gas channel, and the principle is that air enters from a carbon removal port to burn off a deposited graphite layer and a deposited tar layer.
When the coke oven gas exchange cock 130 is closed, the air can enter the carbon removing hole 131, the air is directly replaced in the coke oven gas transverse pipe 120, the coke oven gas loose joint 250 on part of the coke oven gas vertical pipe 220 is removed, and the coke oven gas vertical pipe 220 is sealed by the blank cap 210, at the moment, the coke oven gas main pipe 110 and the vertical fire pipe are safely disconnected, and the coke oven gas cannot leak.
Referring to fig. 4 and 5, an air connection pipe 230 and an air vertical pipe 240 are sequentially connected to an air horizontal pipe 150, an air union 180 is installed on a portion of the air connection pipe 230, and a flow orifice plate 181 is installed in the air union 180 to communicate the air horizontal pipe 150 with the vertical pipe. The flow orifice plate 181 is provided with through holes 182 which are uniformly distributed, and the through holes 182 are used for air to pass through.
Referring to fig. 1-3, pulling the pull-strip 170 controls the opening of the air exchange faucet 160 to replenish the combustion chamber with sufficient air. Specifically, the air exchange cock 160 comprises a housing 164, a sealing head 168 and a cock plate handle 161, wherein the housing 164 has a circular cavity 165 therein, the housing 164 includes an air inlet 166 and an air outlet 167 which are oppositely disposed, the air inlet 166 and the air outlet 167 are respectively disposed at two opposite sides of the circular cavity 165, the sealing head 168 has an arc-shaped structure, the sealing head 168 is movably attached to a sidewall of the circular cavity 165, one end of the cock plate handle 161 extends into the circular cavity 165 and is rotatably connected with the housing 164, the cock plate handle 161 is further connected with the sealing head 168, the other end of the cock plate handle 161 extends out of the housing 164 and is connected to a pull bar 170, and the pull bar 170 drives the other end of the cock plate handle 161 to drive the sealing head 168 to rotate relative to the center of the circular cavity 165.
In fig. 2 the plug plate handle 161 is rotated 45 to the left relative to the vertical centerline so that the head 168 is just between the inlet 166 and the outlet 167, thereby placing the inlet 166 in communication with the outlet 167. In fig. 3, the plug plate handle 161 is rotated 45 ° to the right with respect to the vertical center line, so that the head 168 just blocks the air inlet 166, and thus the air inlet 166 is blocked from the air outlet 167.
The plug plate handle 161 is provided with a waist-shaped hole 162, the waist-shaped hole 162 extends along the length direction of the plug plate handle 161, and the pull strip 170 is connected to the waist-shaped hole 162 through a screw 163, so that the connecting position of the pull strip 170 on the plug plate handle 161 can move along the length direction of the waist-shaped hole 162, and the pull strip 170 is provided with a margin for vertical movement.
The coke oven gas exchange cock 130 is similar in construction to the air exchange cock 160 and will not be described in detail herein.
Because the pressure of the air is about 400000pa, and the pressure of the blast furnace gas is different from 7000-10000pa, a flow orifice plate 181 needs to be arranged in the air loose joint 180 to adjust the air pressure and the flow in the fire-fighting pipeline, when the pressure is too high and the injection speed is high, the high-efficiency heating of the flame in the coke oven is influenced, and the influence of too large and too small flow on the oven temperature is large.
For example, 4.3 meters, each combustion chamber burning approximately 70m of blast furnace gas3H, coke oven gas about 13m3The volume ratio of the blast furnace gas to the air is about 1: 1.5, the dosage ratio of the coke oven gas to the air is about 1: 4. therefore, it is necessary to add a flow orifice 181 to regulate the flow of air in the de-firing line.
The coke oven heating system 100 of the present embodiment can also control the coke oven gas exchange cock 130 and the air exchange cock 160 to open or close by observing the flame status through the pull bar 170, and replace the flow orifice plate 181 to allow the gas to burn sufficiently. Specifically, the condition of gas combustion can be judged whether the matching of gas and air is proper or not by observing the flame state besides calculating the excess coefficient by analyzing waste gas, and the specific judgment process is as follows:
when the coke oven gas is burned:
(1) in the case of normal coking: the flame holes are rice yellow in the daytime, the flame nozzles are far away from the flame path of the circulating holes, and the flame is in a shape of a slender torch and is slightly white; the flame nozzle is close to the flame path of the circulating hole, and the flame and the waste gas are mixed to fill the flame path.
(2) When the air is more and the gas is less: the flame is short, and is white, bright and dazzling in daytime;
(3) when the air is less and the gas is more: the flame is dark and smokes; when the air and the coal gas are less, the flame is smaller compared with the flame path with the same size;
(4) if there is more air and gas, the flame is bigger than the flame path with the same size. In order to judge the flame, in addition to the flame of the ascending air flow, the color of the bottom of the descending air flow should be observed to judge the temperature.
When the blast furnace gas is used for heating:
since the burning flame is blue-transparent, it is difficult to accurately grasp the burning state by observing the flame state. Therefore, whether the matching of the gas and the air is proper or not is judged according to the position of the flame, and the specific judgment process is as follows:
(1) since the amount of gas is larger than the amount of air in many cases, the normal flame is not in the middle but is biased toward the air chute port.
(2) When mixed gas is used, the position of the flame is different according to the size of the mixing ratio, and the larger the mixing ratio is, the more the flame is deviated to the gas inclined channel port.
(3) If the flame is too much deviated to the air inclined channel opening, the air is less and the coal gas is more; if the inclined direction is deviated to the coal gas inclined road junction, the opposite is true.
(4) When the temperature is low, the blue flame is seen more clearly, and the higher the temperature is, the less noticeable. At the moment, the color depth of the two ramp openings can be used for judging which ramp opening has a darker color, namely more gas amount; the degree of turbidity in the flame path can be judged, and the flame path is clear and unmixed normally, and the more turbid, the more gas amount. When the gas amount is too much, a blue flame emerges from the fire hole.
Thus, the coke oven gas exchange cock 130 and the air exchange cock 160 are controlled to open or close by the pull bar 170 and the flow orifice plate 181 is replaced to allow the gas to be sufficiently burned, depending on the observed flame conditions, including the color and location of the flame.

1. on the basis of the existing coke oven structure, a set of air supply system is added and organically combined with a coke oven gas heating system to form a new coke oven heating system 100. The system forms the combination of one path of air system and one path of high-gas coke-charging system;
2. after the coke oven heating system 100 provided by the embodiment is adopted, the coke cake maturation of the coking chamber is greatly improved, the phenomena of difficult coke pouring and coke pushing do not occur, the temperature of the combustion chamber is increased to be over 80 ℃, and the maturation of the coke cake is effectively ensured;
3. because the damage to the coke tank of the coke quenching car is avoided, the maintenance cost of the coke tank is reduced, the damage of the green coke to the furnace wall is reduced, and the service life of the coke furnace is prolonged;
4. under the condition of ensuring the maturity of the coke cake, the coal gas for heating is obviously reduced after the implementation, the blast furnace gas flow is saved by 1000 cubic meters per hour, the coke oven gas is saved by 100 cubic meters, and the blast furnace gas is 0.1 yuan/m3Coke oven gas 1 yuan/m3The gas cost is saved by more than 170 ten thousand yuan each year;
