Here, in providing a pair of regenerative combustion devices in the heating furnace as described above, generally, as shown in FIG. 1, each regenerative combustion device 1a, 1b is provided with fuel gas supply pipes 2a, 2b, respectively. Burner portions 3a and 3b and heat storage chambers 5a and 5b in which the heat storage materials 4a and 4b are accommodated, and combustion air is supplied from the air supply device 6 to the heat storage chambers 5a and 5b in the heat storage combustion devices 1a and 1b. Switching valves 7a and 7b are respectively provided in the air guide path 7 for guiding the air to the heat storage chambers 5a and 5b through the air guide path 7 from the air supply device 6 by switching the opening and closing of the switching valves 7a and 7b. I am trying to supply. On the other hand, switching valves 9a and 9b are provided in the exhaust gas guide paths 9 for guiding the combustion exhaust gas in the heating furnace 10 from the heat storage chambers 5a and 5b in the heat storage combustion apparatuses 1a and 1b to the exhaust apparatus 8, respectively.

After storing heat in the heat storage materials 4a and 4b accommodated in the chambers 5a and 5b, the combustion exhaust gas is guided to the exhaust device 8 through the exhaust gas guide path 9 and discharged to the outside.
そして、このように加熱炉１０に対になった蓄熱式燃焼装置１ａ，１ｂを設け、一方の蓄熱式燃焼装置１ａにおいて燃料ガスを燃焼させる燃焼動作を行う場合には、上記の空気案内経路７に設けられた一方の切換弁７ａを開ける一方、他方の切換弁７ｂを閉じて、給気装置６から空気案内経路７を通して燃焼用空気を一方の蓄熱式燃焼装置１ａにおける蓄熱室５ａに導き、この蓄熱室５ａ内において蓄熱された蓄熱材４ａにより燃焼用空気を加熱させてバーナ部３ａに導くと共に、このバーナ部３ａにおける燃料ガス供給管２ａから燃料ガスを噴射させて、この燃料ガスを燃焼させるようにする。
When the regenerative combustion apparatus 1a, 1b paired with the heating furnace 10 is provided as described above, and the combustion operation for burning the fuel gas is performed in one regenerative combustion apparatus 1a, the air guide path 7 described above is used. One switching valve 7a provided in the engine is opened, while the other switching valve 7b is closed, and combustion air is guided from the air supply device 6 through the air guide path 7 to the heat storage chamber 5a in the one heat storage combustion device 1a.

I will let you.
また、他方の蓄熱式燃焼装置１ｂにおいて蓄熱動作を行う場合には、上記の排ガス案内経路９に設けられた一方の切換弁９ｂを開いた後に、他方の切換弁９ａを閉じて、上記の排気装置８により加熱炉１０内の燃焼排ガスを他方の蓄熱式燃焼装置１ｂにおける蓄熱室５ｂに導き、燃焼排ガスの熱をこの蓄熱室５ｂ内に収容された蓄熱材４ｂに蓄熱させた後、この燃焼排ガスを蓄熱室５ｂから排ガス案内経路９を通して排気装置８に導いて外部に排出させるようにする。
When the other heat storage type combustion apparatus 1b performs a heat storage operation, after opening one switching valve 9b provided in the exhaust gas guide path 9, the other switching valve 9a is closed and the exhaust gas is discharged. The apparatus 8 guides the combustion exhaust gas in the heating furnace 10 to the heat storage chamber 5b in the other heat storage combustion apparatus 1b, stores the heat of the combustion exhaust gas in the heat storage material 4b accommodated in the heat storage chamber 5b, and then performs this combustion.

そして、本発明の蓄熱式燃焼装置においては、上記の空気案内経路と排ガス案内経路とに設けられた三方切換弁の切り換えを制御する制御装置を設け、上記の給排気装置によって燃焼用空気を蓄熱室に供給する場合には、上記の排ガス案内経路に設けられた三方切換弁に接続された上記の空気導入管を通して給排気装置により燃焼用空気を空気案内経路に導くと共に、この空気案内経路に設けられた三方切換弁を通して燃焼用空気を蓄熱室に供給させるようにする。
In the regenerative combustion apparatus of the present invention, a control device that controls switching of the three-way switching valve provided in the air guide path and the exhaust gas guide path is provided, and the combustion air is stored in the heat supply and exhaust apparatus. When supplying to the chamber, the combustion air is guided to the air guide path by the air supply / exhaust device through the air introduction pipe connected to the three-way switching valve provided in the exhaust gas guide path, and the air guide path. Combustion air is supplied to the heat storage chamber through the provided three-way switching valve.
また、上記のように空気案内経路と排ガス案内経路とに設けられた三方切換弁の切り換えを制御する制御装置を設けた場合において、上記の給排気装置によって蓄熱室を通して排出される燃焼排ガスを排出させる場合には、蓄熱室を通して排出される燃焼排ガスを上記の排ガス案内経路に設けられた三方切換弁を通して給排気装置により空気案内経路に導き、この燃焼排ガスを空気案内経路に設けられた三方切換弁に接続された上記の排ガス排出管を通して外部に排出させるようにする。

本発明における蓄熱式燃焼装置においては、蓄熱室に燃焼用空気を案内する空気案内経路と、蓄熱室を通して排出される燃焼排ガスを案内する排ガス案内経路とを１つの給排気装置に接続させるようにしたため、このような蓄熱式燃焼装置を対にして加熱炉に設けるようにした場合、各蓄熱式燃焼装置において、空気案内経路と排ガス案内経路とが個別に設けられることになる。
In the regenerative combustion apparatus according to the present invention, an air guide path for guiding combustion air to the heat storage chamber and an exhaust gas guide path for guiding combustion exhaust gas discharged through the heat storage chamber are connected to one air supply / exhaust apparatus.
