ている。2. Description of the Related Art As shown in FIG. 8, for example, a regenerative combustion device generally comprises a pair of two regenerative combustion devices 2 and the combustion devices 2 alternately burn fuel. According to this alternate combustion, the position of the flame serving as a heat source changes periodically, and thus there is an effect that the temperature in the furnace becomes uniform. However, in order to use burners with the same amount of combustion as compared with the conventional normal burners, it is necessary to install twice the number of burners. Needs to be doubled, so that no matter which type is selected, the furnace wall area is almost twice as large as that of a conventional burner, and this problem hinders the spread of regenerative combustion devices. .

In this regenerative combustion device, gas passages are arranged on both sides of a fuel nozzle, and the combustion gas ejected from one gas passage is used to burn the fuel ejected from the fuel nozzle while the other gas passage is used. A first state in which the in-furnace exhaust gas is sucked from the passage, and a second state in which the combustion air ejected from the other gas flow path is used for fuel combustion and the in-furnace exhaust gas is sucked from the one gas flow path.

You. This kills the feature of the regenerative combustion device that attempts to equalize the furnace temperature by periodically changing the flame position. Further, there is a problem that the NOx concentration is high because the combustion air heated to a high temperature due to the contact with the heat storage body is jetted toward the fuel.

In addition, the gas flow path is arranged so as to move away from the surface as it goes to the front end. Note that the two gas flow paths may be branched into two or more from the portion where the regenerator is filled to the tip of the burner. Further, the direction of the fuel nozzle may have an angle with respect to the central axis in a direction away from the gas flow path. In addition, one around the fuel nozzle
A secondary gas flow path may be provided to eject a part of the combustion air. Further, it is preferable that the ejection of the combustion air from the primary gas flow path be stopped when the furnace temperature becomes equal to or higher than the fuel ignition point.

As a result, the mixing speed of the fuel and the air is reduced, the combustion temperature is reduced, and the NOx is reduced. Further, the flame is formed so as to be deviated in each blowing direction of the combustion air. That is, the position of the flame moves periodically. Therefore, the temperature in the furnace becomes uniform, and the material to be processed in the furnace is heated equally.

振られ、これにより炉内の温度が均一になる。The regenerative combustion device 1 configured as described above
0 is fixed to the furnace wall 36 as shown in FIG. Also,
The fuel nozzle 18 is connected to a fuel supply device, and each of the supply / exhaust ports 34A and 34B is connected to an air supply device and an exhaust gas suction device via a switching valve. Next, the operation of the regenerative combustion device 10 will be described. Now, as shown in FIG. 3, combustion air is blown out from one gas flow path 26A to burn the fuel blown out from the fuel discharge port 16, and the other gas flow path 26A is burned.
Exhaust gas in the furnace is exhausted from B. in this case,
The fuel jetted from the fuel nozzle 18 through the fuel jet port 16 emits radial regions 38A and 38B around the surface 20.
Spread between. Further, the combustion air supplied to the vacant chamber 22A is preheated by the heat storage body 28A, and then is ejected from the gas flow path 26A and spreads in a radial region 40A obliquely with respect to the surface 20. Then, the fuel and the combustion air are mixed at the end 38A of the fuel ejection region 38 to form a flame 42A. At this time, the exhaust gas in the furnace is sucked from the other gas flow path 26B, and the heat is recovered by the heat storage body 28B and exhausted from the supply / exhaust port 34B. After a predetermined time, the switching valve is switched, the combustion air is ejected from the other gas passage 26B to burn the fuel ejected from the fuel ejection port 16, and the exhaust gas in the furnace is exhausted from the one gas passage 26A. You will be in a state to do. In this state, as shown in FIG.
The fuel ejected from the fuel through the fuel ejection port 16 spreads between the radial regions 38A and 38B around the surface 20.
Further, the combustion air supplied to the empty room 22B is stored in the heat storage body 28.
After being preheated in the gas flow path 26B,
It extends to a radial region 40B which goes obliquely with respect to 0.
Then, the fuel and the air are mixed at the end 38B of the fuel ejection region 38 to form a flame 42B. At this time, the exhaust gas in the furnace is sucked from the other gas flow path 26B, and the heat is recovered by the heat storage body 28A and exhausted from the supply / exhaust port 34A. The above two states are alternately repeated at predetermined time intervals, and the flames 42A and 42B are largely swung right and left at predetermined time intervals, whereby the temperature in the furnace becomes uniform.

The gas flow path may be further branched into two parts from 2A, 22B to the tip of the burner, and two gas flow paths 26A, 26A ', 26B, 26B' may be provided left and right symmetrically. In this case, there is an advantage that the flame position and the flame shape can be controlled more accurately.

ることができる。Furthermore, in the regenerative combustion device 10 of the present invention, the overlap between the fuel ejection region and the combustion air ejection region is reduced, so that the furnace temperature is low for a while after the start of the furnace operation. Then, the fuel is difficult to ignite and the flame is not stable. Therefore, as in the regenerative combustion device 10C shown in FIG. 7, a passage 44 for the primary air is formed around the fuel nozzle 18, and the combustion air flows through the passage 44 until the temperature in the furnace exceeds the ignition point of the fuel. Preferably, a portion is supplied to burn the fuel. However, the air supply from the passage 44 may be always performed, in which case, even when the combustion air is switched from the state in which the combustion air is ejected from the gas flow path to the other gas flow path, or vice versa. Thus, the combustion state of the fuel can be stabilized.
