In the firing furnace, the gas evaporated from the work contains an organic vapor. Vaporized gas can adversely affect the workpiece. For this reason, in the firing furnace, the inside of the furnace may be ventilated. Ventilation reduces the internal temperature of the firing furnace. For this reason, heat exchange is performed between the exhaust from the furnace and the intake air into the furnace.

高温気体の熱を回収して低温気体を加熱する熱回収装置は、熱回収の効率を高めることが望まれる。また、その製造コストの抑制も望まれる。   A heat recovery apparatus that recovers heat of a high-temperature gas and heats the low-temperature gas is desired to increase the efficiency of heat recovery. Moreover, suppression of the manufacturing cost is also desired.

この発明の目的は、従来よりも熱回収効率を高めることができ、製造コストの抑制が可能な熱回収装置を提供することにある。   An object of the present invention is to provide a heat recovery apparatus that can increase the heat recovery efficiency as compared with the prior art and can suppress the manufacturing cost.

この発明の熱回収装置は、高温チャンバの内部を経由する高温気体の通気路と、高温気体の通気路とは非連続に設けられ、低温チャンバの内部を経由する低温気体の通気路と、高温チャンバの内部の一部である吸熱領域で高温気体から熱を吸熱し、低温チャンバの内部の一部である放熱領域で前記低温気体に熱を放熱する熱交換器と、低温気体が高温チャンバの外壁面に沿って流れるように高温チャンバを内装する主予熱室と、低温気体が低温チャンバの外壁面に沿って流れるように低温チャンバを内装する副予熱室と、を備える。低温気体の通気路は、主予熱室内における高温チャンバの外壁面、副予熱室内における前記低温チャンバの外壁面、低温チャンバの内部をこの順に経由するように構成されている。 Heat recovery apparatus of the present invention, a vent path of the hot gases passing through the interior of the hot chamber, provided in discontinuous and vent path of hot gas, and air passage of cool gas passing through the interior of the cold chamber, the hot A heat exchanger that absorbs heat from the high temperature gas in a heat absorption region that is part of the interior of the chamber, and dissipates heat to the low temperature gas in a heat dissipation region that is part of the interior of the low temperature chamber; a main preheating chamber for interior hot chamber to flow along the outer wall surface, and the auxiliary preheating chamber which cool gas to interior cold chamber to flow along the outer wall surface of the cold chamber, Ru comprising a. Vent path of cool gas, the outer wall surface of the high-temperature chamber in the main preheating chamber, an outer wall surface of said cold chamber in the secondary pre-heating chamber, that is configured so as to pass through the inside of the cold chamber in this order.

したがって、熱交換器が高温気体から低温気体に熱を回収する。さらに、予熱室が高温気体の漏出熱を低温気体に回収する。これにより、熱回収装置の熱回収効率が高まる。また、高温気体の通気路に断熱処理を行う必要が無い。したがって、熱回収装置に設ける断熱材を抑制し製造コストを抑制することが可能になる。   Thus, the heat exchanger recovers heat from the hot gas to the cold gas. Further, the preheating chamber recovers the leaked heat of the high temperature gas into the low temperature gas. Thereby, the heat recovery efficiency of the heat recovery device is increased. Further, it is not necessary to perform heat insulation treatment on the hot gas passage. Therefore, it becomes possible to suppress the heat insulating material provided in the heat recovery apparatus and suppress the manufacturing cost.

前記高温気体の通気路における前記吸熱領域の前段に設けた、前記高温気体に含まれる有機物成分を分解する浄化部を備え、前記主予熱室は、前記浄化部が内部に配置され、前記浄化部の外壁面からの漏出熱を前記低温気体に吸熱させると好適である。A purification unit for decomposing an organic component contained in the high-temperature gas, provided in a stage preceding the endothermic region in the high-temperature gas ventilation path, wherein the purification unit is disposed in the main preheating chamber; It is preferable that the low-temperature gas absorbs heat leaked from the outer wall surface.

前記低温チャンバは、筒状であり、一端が前記副予熱室の内部で開口し、他端が前記副予熱室および前記主予熱室の外部で開口すると好適である。 It is preferable that the low temperature chamber has a cylindrical shape, and has one end opened inside the sub preheating chamber and the other end opened outside the sub preheating chamber and the main preheating chamber.

副予熱室に放熱領域を内装してもよい。この場合、高温気体の通気路の吸気口と、低温気体の通気路の排気口とを同方向に向けると好適である。   A heat dissipation area may be provided in the auxiliary preheating chamber. In this case, it is preferable that the intake port of the high temperature gas passage and the exhaust port of the low temperature gas passage be directed in the same direction.

熱回収装置は、ブロワ部を備えてもよい。ブロワ部は、高温気体の通気路における吸熱領域の後段で高温気体の通気路の排気口の前段に設けられて、高温気体の流体圧を調整する。   The heat recovery apparatus may include a blower unit. The blower section is provided in the subsequent stage of the heat absorption region in the hot gas ventilation path and in the previous stage of the exhaust port of the hot gas ventilation path to adjust the fluid pressure of the hot gas.

この発明によれば、熱回収装置は高温気体の通気路からの漏出熱を回収でき、熱回収装置の熱回収効率を従来よりも高められる。そのため、断熱材などを抑制でき、製造コストを低減可能になる。   According to the present invention, the heat recovery device can recover the heat leaked from the hot gas ventilation passage, and the heat recovery efficiency of the heat recovery device can be improved as compared with the conventional case. Therefore, a heat insulating material etc. can be suppressed and manufacturing cost can be reduced.

以下、図面を参照して熱回収装置の構成例を説明する。ここでの熱回収装置は、液晶表示パネルの製造工程に用いられる多段焼成炉の換気に用いる。多段焼成炉からの排気ガスには、バインダーなどの蒸散によって有機物成分が含まれる。熱回収装置は、この排気ガスを炉外に排気し、外気を焼成炉に吸気する。   Hereinafter, a configuration example of the heat recovery apparatus will be described with reference to the drawings. The heat recovery apparatus here is used for ventilation of a multi-stage firing furnace used in the manufacturing process of the liquid crystal display panel. The exhaust gas from the multi-stage firing furnace contains an organic component by transpiration of a binder or the like. The heat recovery device exhausts the exhaust gas to the outside of the furnace and sucks the outside air into the firing furnace.

図１は、熱回収装置の側面断面図である。ここでは固定配置式の熱回収装置１００を示している。なお、熱回収装置１００の底面に移動ローラを設けるなどして、熱回収装置１００を可動式にしてもよい。   FIG. 1 is a side sectional view of the heat recovery apparatus. Here, a fixed arrangement type heat recovery apparatus 100 is shown. The heat recovery apparatus 100 may be movable by providing a moving roller on the bottom surface of the heat recovery apparatus 100.

熱回収装置１００は外装体１を備える。外装体１の内部は、制御室１１と主予熱室１２と副予熱室１３とに区画されている。制御室１１は制御部６を内装する。主予熱室１２は、高温チャンバ２と掃気ブロワ５とを内装する。副予熱室１３は、低温チャンバ３を内装する。主予熱室１２を構成する外装体１の壁面には、高温気体吸気口１６と高温気体排気口１７と低温気体吸気口１８とが設けられている。副予熱室１３を構成する外装体１の壁面には、低温気体排気口１９が設けられている。主予熱室１２と副予熱室１３との間には隔壁１４が設けられている。隔壁１４には、主予熱室１２と副予熱室１３との間を通気するための通気口１５が設けられている。   The heat recovery apparatus 100 includes an exterior body 1. The interior of the exterior body 1 is partitioned into a control chamber 11, a main preheating chamber 12, and a sub preheating chamber 13. The control room 11 includes a control unit 6. The main preheating chamber 12 includes a high temperature chamber 2 and a scavenging blower 5. The sub preheating chamber 13 includes the low temperature chamber 3. A high-temperature gas inlet 16, a high-temperature gas outlet 17, and a low-temperature gas inlet 18 are provided on the wall surface of the exterior body 1 constituting the main preheating chamber 12. A low-temperature gas exhaust port 19 is provided on the wall surface of the exterior body 1 constituting the auxiliary preheating chamber 13. A partition wall 14 is provided between the main preheating chamber 12 and the sub preheating chamber 13. The partition wall 14 is provided with a vent hole 15 for ventilating between the main preheating chamber 12 and the sub preheating chamber 13.

制御室１１は、主予熱室１２および副予熱室１３から分離されている。なお、制御室１１は図示しない断熱材により囲まれる。したがって、主予熱室１２および副予熱室１３から制御室１１への熱伝導が抑制される。制御部６は、熱回収装置１００の換気能力を維持するために、掃気ブロワ５を制御する。また、制御部６は、熱回収装置１００の換気能力の低下を、警告音や警告表示の形式で管理者に報知する。   The control chamber 11 is separated from the main preheating chamber 12 and the sub preheating chamber 13. The control chamber 11 is surrounded by a heat insulating material (not shown). Therefore, heat conduction from the main preheating chamber 12 and the sub preheating chamber 13 to the control chamber 11 is suppressed. The control unit 6 controls the scavenging blower 5 in order to maintain the ventilation capability of the heat recovery apparatus 100. Moreover, the control part 6 alert | reports the fall of the ventilation capability of the heat recovery apparatus 100 to an administrator in the form of a warning sound or a warning display.

低温チャンバ３は、流路方向の断面が矩形状の筒状部材である。低温チャンバ３の両端は開口している。また、両端付近の断面積が中央よりも小さくされている。低温チャンバ３の一端は、低温気体排気口１９から外装体１の外に退出する。この一端は、図示しない焼成炉に外気を排気する。低温チャンバ３の他端は、副予熱室１３の内部に配置されている。低温チャンバ３の内部には、放熱領域３１が設けられている。   The low temperature chamber 3 is a cylindrical member having a rectangular cross section in the flow path direction. Both ends of the low temperature chamber 3 are open. Moreover, the cross-sectional area near both ends is made smaller than the center. One end of the low temperature chamber 3 exits from the low temperature gas exhaust port 19 to the outside of the exterior body 1. This one end exhausts outside air to a firing furnace (not shown). The other end of the low temperature chamber 3 is disposed inside the sub preheating chamber 13. Inside the low temperature chamber 3, a heat radiation area 31 is provided.

放熱領域３１は、副予熱室１３から吸気する外気に熱を放熱する。そのため、放熱領域３１の内部には熱交換ユニット４の一部を配している。熱交換ユニット４の構成については後述する。   The heat radiation area 31 radiates heat to the outside air sucked from the sub preheating chamber 13. Therefore, a part of the heat exchange unit 4 is arranged inside the heat radiation area 31. The configuration of the heat exchange unit 4 will be described later.

高温チャンバ２は、流路方向の断面が矩形状の筒形部材である。高温チャンバ２の両端は開口している。また、両端付近の断面積が中央よりも小さくされている。高温チャンバ２の一端は、高温気体吸気口１６から外装体１の外に退出する。この一端には、図示しない焼成炉から排気ガスが吸気される。高温チャンバ２の他端は、主予熱室１２の内部に配置されている。高温チャンバ２の内部には、フィルタ室２１と浄化部２２と吸熱領域２３とが設けられている。   The high temperature chamber 2 is a cylindrical member having a rectangular cross section in the flow path direction. Both ends of the high temperature chamber 2 are open. Moreover, the cross-sectional area near both ends is made smaller than the center. One end of the high temperature chamber 2 exits from the high temperature gas inlet 16 to the outside of the exterior body 1. At one end, exhaust gas is sucked from a firing furnace (not shown). The other end of the high temperature chamber 2 is disposed inside the main preheating chamber 12. Inside the high temperature chamber 2, a filter chamber 21, a purification unit 22, and an endothermic region 23 are provided.

フィルタ室２１は、焼成炉からの排気ガス中から、ダストやミストを除去する。そのため、フィルタ室２１には、複数のフィルタ粒を堆積させている。フィルタ粒を用いることで、熱回収装置１００の稼働中でも、フィルタ粒の交換が可能になり、フィルタ室２１内の清浄度を高く維持できる。したがって、後段の浄化部２２にダストやミストが付着することがない。このためダストやミストの付着による浄化部２２での触媒による有機物分解能の低減が防げ、浄化部２２のメンテナンス回数を低減できる。   The filter chamber 21 removes dust and mist from the exhaust gas from the firing furnace. Therefore, a plurality of filter particles are deposited in the filter chamber 21. By using the filter particles, the filter particles can be exchanged even during operation of the heat recovery apparatus 100, and the cleanliness in the filter chamber 21 can be maintained high. Therefore, dust and mist do not adhere to the subsequent purification unit 22. For this reason, reduction of the organic substance resolution by the catalyst in the purification unit 22 due to adhesion of dust or mist can be prevented, and the number of maintenance of the purification unit 22 can be reduced.

なお、図示していないが、フィルタ室２１の直前および直後には、圧力検出部を設けている。これらの圧力検出部の検出した排気ガスの流体圧データは制御部６に出力する。制御部６では、この圧力変化に基づいて、フィルタ室２１の目詰まりを検知する。そして、目詰まりが生じた場合に、そのことを報知する警告音や警告表示を出力する。また、掃気ブロワ５の掃気能を調整し、圧力変化を補正して安定化させる。   Although not shown, a pressure detector is provided immediately before and immediately after the filter chamber 21. The fluid pressure data of the exhaust gas detected by these pressure detectors is output to the controller 6. The control unit 6 detects clogging of the filter chamber 21 based on this pressure change. Then, when clogging occurs, a warning sound or warning display for informing that is output. Further, the scavenging ability of the scavenging blower 5 is adjusted to correct and stabilize the pressure change.

浄化部２２は、フィルタ室２１を通過した排気ガス中の有機物成分を分解する。そのため、浄化部２２内部には触媒（ここでは、ヒータ付きの白金触媒）を設けている。この触媒により、有機物成分を酸化反応させ、排気ガス中の有機物成分を二酸化炭素などに分解する。したがって、後段の吸熱領域２３には有機物成分が流入することがない。そのため有機物成分による吸熱領域２３での熱交換効率の低減が防げ、吸熱領域２３のメンテナンス回数を低減できる。また、浄化部２２に流入する排気ガスは、触媒によって加熱される。具体的には、ヒータによる加熱と、有機物の分解反応で生じる熱とにより、排気ガスの温度が約１０℃〜１００℃ほど昇温する。したがって、後段の吸熱領域２３では、より多くの熱交換がなされる。   The purification unit 22 decomposes organic components in the exhaust gas that has passed through the filter chamber 21. For this reason, a catalyst (in this case, a platinum catalyst with a heater) is provided inside the purification unit 22. With this catalyst, the organic component is oxidized and the organic component in the exhaust gas is decomposed into carbon dioxide. Therefore, the organic component does not flow into the latter endothermic region 23. Therefore, it is possible to prevent the heat exchange efficiency in the endothermic region 23 from being reduced by the organic component, and the maintenance frequency of the endothermic region 23 can be reduced. Further, the exhaust gas flowing into the purification unit 22 is heated by the catalyst. Specifically, the temperature of the exhaust gas is raised by about 10 ° C. to 100 ° C. by the heating by the heater and the heat generated by the decomposition reaction of the organic matter. Therefore, more heat exchange is performed in the heat absorption region 23 at the subsequent stage.

なお、図示していないが、浄化部２２の直前および直後には、温度検出部を設けている。これらの温度検出部の検出した排気ガスの温度データは制御部６に出力する。制御部６では、この温度変化に基づいて、触媒の有機物分解能を検知する。そして、有機物分解能が所定値以下に低下した場合に、そのことを報知する警告音や警告表示を出力する。   Although not shown, a temperature detection unit is provided immediately before and immediately after the purification unit 22. The exhaust gas temperature data detected by these temperature detection units is output to the control unit 6. The controller 6 detects the organic matter resolution of the catalyst based on this temperature change. And when organic substance resolution falls below a predetermined value, the warning sound and warning display which alert | report that are output.

吸熱領域２３は、浄化部２２を通過する排気ガスから熱を回収する。そのため、吸熱領域２３の内部には熱交換ユニット４の一部を配している。この熱交換ユニット４の他の一部は、低温チャンバ３の放熱領域３１にも配されている。   The endothermic region 23 recovers heat from the exhaust gas that passes through the purification unit 22. Therefore, a part of the heat exchange unit 4 is arranged inside the endothermic region 23. Another part of the heat exchange unit 4 is also disposed in the heat radiation area 31 of the low temperature chamber 3.

ここで、熱交換ユニット４の構成例を図２に基づいて説明する。   Here, the structural example of the heat exchange unit 4 is demonstrated based on FIG.

図２は熱交換ユニット４の一部を示す斜視図である。熱交換ユニット４は、２次元に配列された複数のパイプ４１を備える。各パイプ４１は、内部が空洞になっていて、空洞に作動流体が封入されている。各パイプ４１は、上述の主予熱室１２と副予熱室１３との間の隔壁１４と、高温チャンバ２の天面と、低温チャンバ３の底面と、に設けられた孔を貫通するように配置される。したがって、各パイプ４１の一端側は、高温チャンバ２内部の吸熱領域２３に配置される。各パイプ４１の他端側は、低温チャンバ３内部の放熱領域３１に配置される。なお、図示していないが、各パイプ４１には、それぞれの軸方向に垂直なフィンが形成される。また、各パイプ４１と隔壁１４との間には、高温チャンバ２内部と低温チャンバ３内部との気密を保つ気密部材が設けられる。   FIG. 2 is a perspective view showing a part of the heat exchange unit 4. The heat exchange unit 4 includes a plurality of pipes 41 arranged two-dimensionally. Each pipe 41 has a hollow inside, and a working fluid is sealed in the hollow. Each pipe 41 is arranged so as to pass through holes provided in the partition wall 14 between the main preheating chamber 12 and the sub preheating chamber 13, the top surface of the high temperature chamber 2, and the bottom surface of the low temperature chamber 3. Is done. Therefore, one end side of each pipe 41 is disposed in the heat absorbing region 23 inside the high temperature chamber 2. The other end side of each pipe 41 is disposed in the heat radiation area 31 inside the low temperature chamber 3. Although not shown, each pipe 41 is formed with fins perpendicular to the respective axial directions. In addition, an airtight member is provided between each pipe 41 and the partition wall 14 to maintain the airtightness between the high temperature chamber 2 and the low temperature chamber 3.

パイプ４１内部の作動流体は、高温チャンバ２内の吸熱領域２３で、排気ガスの熱を吸熱して蒸発する。そして、この作動流体は、低温チャンバ３内の放熱領域３１で凝縮して液化し、外気に熱を放熱する。これにより、高温チャンバ２内の高温気体が冷却され、低温チャンバ３内の低温気体が加熱される。この熱交換ユニット４は、小さい温度差であっても高効率に熱エネルギーを交換できる。   The working fluid inside the pipe 41 evaporates by absorbing the heat of the exhaust gas in the heat absorbing region 23 in the high temperature chamber 2. The working fluid is condensed and liquefied in the heat radiation area 31 in the low temperature chamber 3 to radiate heat to the outside air. Thereby, the high temperature gas in the high temperature chamber 2 is cooled, and the low temperature gas in the low temperature chamber 3 is heated. The heat exchange unit 4 can exchange heat energy with high efficiency even with a small temperature difference.

掃気ブロワ５には、高温チャンバ２の前記他端が接続される。掃気ブロワ５は、回転する内部フィンの回転速度の調整により高温チャンバ２内に負圧をかけ、排気ガスを吸引する。掃気ブロワ５に吸引された排気ガスは、高温気体排気口１７から熱回収装置１００の外部に排気される。   The other end of the high temperature chamber 2 is connected to the scavenging blower 5. The scavenging blower 5 applies a negative pressure to the high temperature chamber 2 by adjusting the rotation speed of the rotating internal fins, and sucks the exhaust gas. The exhaust gas sucked into the scavenging blower 5 is exhausted to the outside of the heat recovery apparatus 100 from the high temperature gas exhaust port 17.

掃気ブロワ５は、排気ガスを熱回収装置１００の外部に排気し、高温チャンバ２内に負圧をかける。高温チャンバ２は高温気体吸気口１６を介して、図示しない焼成炉に負圧をかける。この焼成炉は低温気体排気口１９を介して低温チャンバ３内に負圧をかける。低温チャンバ３は副予熱室１３内に負圧をかける。副予熱室１３は通気口１５を介して主予熱室１２内に負圧をかける。主予熱室１２は低温気体吸気口１８を介して熱回収装置１００の外部から外気を吸気する。   The scavenging blower 5 exhausts the exhaust gas to the outside of the heat recovery apparatus 100 and applies a negative pressure in the high temperature chamber 2. The high temperature chamber 2 applies a negative pressure to a firing furnace (not shown) through the high temperature gas inlet 16. This firing furnace applies a negative pressure into the low temperature chamber 3 through the low temperature gas exhaust port 19. The low temperature chamber 3 applies a negative pressure in the auxiliary preheating chamber 13. The sub preheating chamber 13 applies a negative pressure to the main preheating chamber 12 through the vent 15. The main preheating chamber 12 draws outside air from the outside of the heat recovery apparatus 100 through the low temperature gas inlet 18.

低温気体吸気口１８から吸気される外気は、掃気ブロワ５および高温チャンバ２の外壁面を沿って流れる。この間に、外気は掃気ブロワ５及び高温チャンバ２の漏出熱を吸熱する。その後、外気は通気口１５を介して主予熱室１２から副予熱室１３の内部に吸入される。その後、外気は副予熱室１３内部を、低温チャンバ３の外壁面に沿って流れる。この間に、外気は低温チャンバ３の漏出熱を吸熱する。その後、外気は低温チャンバ３の内部に吸入される。この間に、外気は低温チャンバ３の内部の放熱領域３１で熱を吸熱する。その後、外気は低温気体排気口１９から焼成炉に排気される。   The outside air sucked from the low temperature gas inlet 18 flows along the scavenging blower 5 and the outer wall surface of the high temperature chamber 2. During this time, the outside air absorbs the leakage heat of the scavenging blower 5 and the high temperature chamber 2. Thereafter, outside air is sucked from the main preheating chamber 12 into the sub preheating chamber 13 through the vent 15. Thereafter, the outside air flows in the auxiliary preheating chamber 13 along the outer wall surface of the low temperature chamber 3. During this time, the outside air absorbs the heat leaked from the low temperature chamber 3. Thereafter, the outside air is sucked into the low temperature chamber 3. During this time, the outside air absorbs heat in the heat radiation area 31 inside the low temperature chamber 3. Thereafter, the outside air is exhausted from the low temperature gas exhaust port 19 to the firing furnace.

したがって、熱回収装置１００は、焼成炉からの高温の排気ガスから低温の外気に、熱交換ユニット４で熱を回収するとともに、高温チャンバ２の外壁面から漏出する漏出熱を回収できる。したがって、熱回収装置１００の熱回収効率は極めて高いものになる。そのため、高温チャンバ２や低温チャンバ３の外装面に断熱材を設ける必要が無く、製造コストが低減される。   Therefore, the heat recovery apparatus 100 can recover heat from the high-temperature exhaust gas from the firing furnace to the low-temperature outside air by the heat exchange unit 4 and also the leakage heat leaking from the outer wall surface of the high-temperature chamber 2. Therefore, the heat recovery efficiency of the heat recovery apparatus 100 is extremely high. Therefore, it is not necessary to provide a heat insulating material on the exterior surface of the high temperature chamber 2 or the low temperature chamber 3, and the manufacturing cost is reduced.

また、浄化部２２で排気ガス中の有機物成分を除去して、有機物成分が外気を汚染することを無くすことができる。その際に、有機物成分の分解により生じる熱エネルギーも、回収する熱の一部となる。また、フィルタ室２１で排気ガス中のダストやミストを除去するが、稼働中に補充および取り出し可能なフィルタ粒を用いることで、メンテナンス性を高め、熱回収装置１００の稼働時間や寿命を高められる。   Further, the organic component in the exhaust gas can be removed by the purification unit 22 so that the organic component can be prevented from polluting the outside air. At that time, thermal energy generated by the decomposition of the organic component also becomes a part of the recovered heat. Further, dust and mist in the exhaust gas are removed in the filter chamber 21. By using filter particles that can be replenished and taken out during operation, maintainability is improved, and the operation time and life of the heat recovery apparatus 100 can be increased. .

ここでは、主予熱室１２と副予熱室１３との間には隔壁１４に設けた通気口１５を、低温気体吸気口１８から離して、高温気体吸気口１６と低温気体排気口１９とに近接させている。これにより、主予熱室１２における低温気体の通気路を長く確保して、低温気体である外気に十分に漏出熱を吸収させる。また、高温気体吸気口１６を外装体１の低温気体排気口１９と同一側面に設けている。これにより、高温気体の通気路の吸気口と低温気体の通気路の排気口とが同方向に向く。したがって、この外装体１の側面を焼成炉方向に向けることで、焼成炉への配管接続を容易に行える。なお、高温気体吸気口１６と低温気体排気口１９とは必ずしも外装体１の同一側面に設けなくてもよい。   Here, a vent 15 provided in the partition 14 is provided between the main preheating chamber 12 and the sub preheating chamber 13 away from the low temperature gas intake port 18 and close to the high temperature gas intake port 16 and the low temperature gas exhaust port 19. I am letting. This ensures a long passage for the low temperature gas in the main preheating chamber 12 and allows the outside air, which is a low temperature gas, to sufficiently absorb the leakage heat. The high temperature gas inlet 16 is provided on the same side as the low temperature gas outlet 19 of the exterior body 1. As a result, the intake port of the hot gas passage and the exhaust port of the cold gas passage are oriented in the same direction. Therefore, the piping connection to the firing furnace can be easily performed by directing the side surface of the exterior body 1 toward the firing furnace. The high temperature gas inlet 16 and the low temperature gas outlet 19 are not necessarily provided on the same side surface of the exterior body 1.
