Description
本發明係關於利用燃料氣體或燃料油作為燃燒所使用之燃料的燃燒裝置、以及使用如此燃燒裝置加熱被處理物之加熱爐。特別是具有以下特徵：可使用燃料氣體與燃料油任一者或兩者作為燃料燃燒裝置所使用之燃料，且修理及維護等可容易進行，此外在同時燃燒燃料油與燃料氣體時，可抑制因燃料油不完全燃燒而使煙灰附著堵塞於油噴嘴之情形。The present invention relates to a combustion apparatus using fuel gas or fuel oil as a fuel for combustion, and a heating furnace for heating a workpiece using such a combustion apparatus. In particular, it is characterized in that any one or both of fuel gas and fuel oil can be used as the fuel used in the fuel combustion apparatus, and repair and maintenance can be easily performed, and when fuel oil and fuel gas are simultaneously burned, it can be suppressed. The case where the soot adheres to the oil nozzle due to incomplete combustion of the fuel oil.
在以往之燃燒裝置中，一般而言使用有使用以燃料氣體作為燃燒所用燃料者、以及以燃料油作為燃燒所用燃料者。In the conventional combustion apparatus, those who use fuel gas as fuel for combustion and fuel oil as fuel for combustion are generally used.
而且，在如此燃燒裝置中燃燒燃料氣體或燃料油時，為了使燃料氣體或燃料油有效率地與燃燒用空氣接觸並燃燒，一般係在噴出燃燒用空氣之空氣噴嘴的內周側，設置噴出燃料氣體之氣體噴嘴、噴出燃料油之油噴嘴，而使燃燒用空氣會噴出於由氣體噴嘴噴出之燃料氣體、由油噴嘴噴出之燃料油的周圍。Further, when the fuel gas or the fuel oil is burned in such a combustion apparatus, in order to efficiently contact the combustion gas or the fuel oil with the combustion air, the fuel gas or the fuel oil is generally disposed on the inner peripheral side of the air nozzle that discharges the combustion air. The gas nozzle of the fuel gas and the oil nozzle that ejects the fuel oil cause the combustion air to be sprayed around the fuel gas ejected from the gas nozzle and the fuel oil ejected from the oil nozzle.
在此，於如此般在噴出燃燒用空氣之空氣噴嘴的內周側設置氣體噴嘴或油噴嘴之燃燒裝置中，在所使用燃料要在燃料氣體與燃料油間轉換時，需要更換配管之工事等，在作業上非常麻煩，且有費時與成本高等各種問題。Here, in the combustion apparatus in which the gas nozzle or the oil nozzle is provided on the inner peripheral side of the air nozzle that ejects the combustion air, when the fuel to be used is to be switched between the fuel gas and the fuel oil, it is necessary to replace the piping, etc. It is very troublesome in operation, and has various problems such as time consuming and high cost.
此外，在以往就使用燃料氣體與燃料油之燃燒裝置而言係如專利文獻1所示，已提出在噴出燃燒用空氣之空氣噴嘴的內周側設置噴出燃料油之油噴嘴，另一方面在空氣噴嘴的外周側設置噴出燃料氣體之氣體噴嘴者。In addition, as shown in Patent Document 1, a combustion apparatus using a fuel gas and a fuel oil has been proposed, and an oil nozzle for discharging fuel oil is provided on the inner peripheral side of the air nozzle for discharging the combustion air. A gas nozzle that ejects fuel gas is disposed on the outer peripheral side of the air nozzle.
但是，在該種燃燒裝置中，因在油噴嘴外周設置空氣噴嘴與氣體噴嘴而成為多重管構造，故有修理或維修等非常麻煩之問題。此外，當欲使油噴嘴與氣體噴嘴同時噴出燃料油與燃料氣體而燃燒時，因燃料氣體比燃料油容易燃燒，故由氣體噴嘴噴出之燃料氣體會先燃燒而消耗其周圍之燃燒用空氣，而由油噴嘴噴出之燃料油會不完全燃燒而產生煙灰，該煙灰會附著於油噴嘴，而產生油噴嘴堵塞等之問題。However, in such a combustion apparatus, since the air nozzle and the gas nozzle are provided on the outer circumference of the oil nozzle to have a multi-tube structure, there is a problem that repair or maintenance is very troublesome. Further, when the fuel nozzle and the gas nozzle are to be simultaneously injected with the fuel oil and the fuel gas to be combusted, since the fuel gas is more likely to be burned than the fuel oil, the fuel gas ejected from the gas nozzle is first burned to consume the combustion air around it. The fuel oil ejected from the oil nozzle may not completely burn to generate soot, which may adhere to the oil nozzle, causing problems such as clogging of the oil nozzle.
此外，近年來為了利用燃燒排氣的熱來使燃燒氣體有效率地燃燒而使用蓄熱式燃燒裝置，其方式係在非燃燒時將加熱爐內之燃燒排氣通過收容有蓄熱材之蓄熱部而排出，而將燃燒排氣的熱蓄熱於蓄熱材，另一方面，在燃燒時將燃燒用空氣通過如此收容有已蓄熱的蓄熱材之蓄熱部而加熱，並將如此經加熱之燃燒用空氣由空氣噴嘴噴出而燃燒燃料氣體。Further, in recent years, in order to efficiently burn the combustion gas by the heat of the combustion exhaust gas, a regenerative combustion apparatus is used, in which the combustion exhaust gas in the heating furnace passes through the heat storage portion in which the heat storage material is accommodated during non-combustion. Exhaust, the heat of the combustion exhaust gas is stored in the heat storage material, and on the other hand, the combustion air is heated by the heat storage portion in which the heat storage material is stored, and the thus-heated combustion air is heated. The air nozzle is ejected to burn the fuel gas.
而且，在如此之蓄熱式燃燒裝置係存在有：將噴出燃料氣體之氣體噴嘴設置在噴出燃燒用空氣之空氣噴嘴的內周側者；或如專利文獻2、3所示，在與噴出燃燒用氣體之空氣噴嘴相隔的位置設置噴出燃料氣體之氣體噴嘴，並向著由空氣噴嘴噴出之燃燒用空氣而由上述氣體噴嘴噴出燃料氣體並燃燒者。Further, in such a regenerative combustion apparatus, the gas nozzle for ejecting the fuel gas is provided on the inner peripheral side of the air nozzle that ejects the combustion air, or as shown in Patent Documents 2 and 3, A gas nozzle that ejects the fuel gas is disposed at a position where the air nozzles of the gas are spaced apart, and the fuel gas is ejected from the gas nozzle and burned toward the combustion air blown by the air nozzle.
但是，在如此之蓄熱式燃燒裝置中係僅設有噴出燃料氣體之氣體噴嘴，故要將所使用燃料由燃料氣體轉換為燃料油時，需要 更換配管之工事等，在作業上非常麻煩，且有費時與成本高之問題。此外，如此僅將由氣體噴嘴噴出之燃料氣體與由空氣噴嘴噴出之燃燒用空氣混合而燃燒，會有難以依目的改變火焰形狀並適切地加熱加熱爐內之被處理物等之問題。However, in such a regenerative combustion apparatus, only a gas nozzle that ejects fuel gas is provided, so when the fuel to be used is converted from fuel gas to fuel oil, it is required The work of replacing the piping, etc., is very troublesome in operation, and has problems of time consuming and high cost. Further, in this case, only the fuel gas ejected from the gas nozzle is mixed with the combustion air ejected from the air nozzle to be burned, and there is a problem in that it is difficult to change the flame shape according to the purpose and appropriately heat the workpiece in the heating furnace or the like.

本發明之課題係在燃燒燃料氣體與燃燒油之燃燒裝置中，可使用燃料氣體與燃料油任一者或兩者作為該燃料，且燃燒裝置之修理及維護等可容易進行，此外在同時燃燒燃料油與燃料氣體時，可抑制因燃料油燃燒不完全而使煙灰附著堵塞於油噴嘴等之現象。An object of the present invention is to use any one or both of fuel gas and fuel oil as the fuel in a combustion apparatus for burning fuel gas and combustion oil, and it is easy to carry out repair and maintenance of the combustion apparatus, and simultaneously burn In the case of the fuel oil and the fuel gas, it is possible to suppress the phenomenon that the soot adheres to the oil nozzle due to incomplete combustion of the fuel oil.
本發明之燃燒裝置為解決上述課題，係具備噴出燃料氣體之氣體噴嘴、噴出燃料油之油噴嘴、以及噴出燃燒用空氣之空氣噴嘴的燃燒裝置，其中，在離開上述空氣噴嘴之不同位置分別設置上述氣體噴嘴與油噴嘴；並向著由上述空氣噴嘴噴出之燃燒用空氣而使燃料氣體由上述氣體噴嘴噴出，另一方面，使燃料油由上述油噴嘴噴出。In order to solve the above problems, the combustion apparatus of the present invention includes a gas nozzle that ejects a fuel gas, an oil nozzle that ejects fuel oil, and a combustion device that ejects an air nozzle for combustion air, wherein each of the air nozzles is disposed at a different position from the air nozzle. The gas nozzle and the oil nozzle are configured to eject the fuel gas from the gas nozzle toward the combustion air blown by the air nozzle, and the fuel oil is ejected from the oil nozzle.
若如此地分別設置噴出燃料氣體之氣體噴嘴與噴出燃料油之 油噴嘴，則燃燒的燃料可在燃料氣體與燃料油間切換，使用燃料氣體與燃料油兩者也可簡單地進行。If so, the gas nozzle that ejects the fuel gas and the fuel oil are separately disposed. In the oil nozzle, the fuel to be burned can be switched between the fuel gas and the fuel oil, and both the fuel gas and the fuel oil can be simply used.
此外，若在離開空氣噴嘴之不同位置分別設置氣體噴嘴與油噴嘴，則在進行修理或維修等時，可將氣體噴嘴與油噴嘴分別取下。Further, if the gas nozzle and the oil nozzle are respectively provided at different positions away from the air nozzle, the gas nozzle and the oil nozzle can be removed separately during repair or maintenance.
而且，若上述燃料裝置中設有調整由上述氣體噴嘴噴出之燃料氣體的量之燃料氣體調整裝置、以及調整由上述油噴嘴噴出之燃料油的量之燃料油調整裝置，則燃燒的燃料可在燃料氣體與燃料油間切換之外，也可適當調整燃燒燃料中燃料氣體與燃料油的比例。結果可依目的適切地進行燃燒，並且若燃料油的比例多，則燃料油燃燒時因光焰而增加熱輻射，可增大放熱，並可謀求縮短加熱時間或省能量化。Further, if the fuel device is provided with a fuel gas adjusting device that adjusts the amount of fuel gas discharged from the gas nozzle, and a fuel oil adjusting device that adjusts the amount of fuel oil discharged from the oil nozzle, the fuel to be burned may be In addition to switching between fuel gas and fuel oil, the ratio of fuel gas to fuel oil in the combustion fuel can also be appropriately adjusted. As a result, combustion can be appropriately performed according to the purpose, and if the ratio of the fuel oil is large, the heat radiation is increased by the flame when the fuel oil is burned, the heat generation can be increased, and the heating time or energy saving can be shortened.
此外，由上述空氣噴嘴噴出之燃燒用空氣與由上述氣體噴嘴噴出之燃料氣體所合流的位置、以及由上述油噴嘴噴出之燃料油與由上述空氣噴嘴噴出之燃燒用空氣所合流的位置若相異，則會使燃料氣體與燃料油在不同位置與燃燒用空氣接觸並燃燒，會抑制燃燒油之不完全燃燒，也可防止因不完全燃燒所產生的煙灰附著於油噴嘴。Further, a position at which the combustion air blown from the air nozzle merges with the fuel gas discharged from the gas nozzle, and a position at which the fuel oil discharged from the oil nozzle merges with the combustion air blown from the air nozzle Differently, the fuel gas and the fuel oil are brought into contact with the combustion air at different positions and burned, and the incomplete combustion of the combustion oil is suppressed, and the soot generated by the incomplete combustion is prevented from adhering to the oil nozzle.
此外，上述燃燒裝置中，若在較由上述空氣噴嘴噴出之燃燒用空氣與由上述氣體噴嘴噴出之燃料氣體所合流的位置更向噴出方向下游側之位置，使由油噴嘴噴出之燃料油與由空氣噴嘴噴出之燃燒用空氣合流，則燃燒之火焰變長，即使在離開燃燒裝置之位置也可充分地加熱。Further, in the above-described combustion apparatus, when the combustion air blown by the air nozzle and the fuel gas discharged from the gas nozzle merge with each other at a position downstream of the discharge direction, the fuel oil discharged from the oil nozzle is When the combustion air jetted from the air nozzles merges, the flame of the combustion becomes long, and the heat can be sufficiently heated even at a position away from the combustion device.
在此，在由空氣噴嘴噴出之燃燒用空氣與由氣體噴嘴噴出之 燃料空氣所合流的位置、以及由油噴嘴噴出之燃料油與由空氣噴嘴噴出之燃燒用氣體所合流的位置相異之情形，可使用以下兩種方法：向著由空氣噴嘴噴出之燃燒用空氣，由上述氣體噴嘴噴出之燃料氣體的燃料氣體噴出角度、與由油噴嘴噴出之燃料油的燃料油噴出角度係相異之方法；或空氣噴嘴與氣體噴嘴之間隔、與空氣噴嘴與油噴嘴之間隔係相異之方法。Here, the combustion air blown by the air nozzle is ejected by the gas nozzle The position at which the fuel air merges and the position at which the fuel oil ejected from the oil nozzle merges with the combustion gas ejected from the air nozzle may be different, and the following two methods may be used: the combustion air ejected from the air nozzle, The fuel gas discharge angle of the fuel gas ejected from the gas nozzle is different from the fuel oil discharge angle of the fuel oil ejected from the oil nozzle; or the interval between the air nozzle and the gas nozzle, and the distance between the air nozzle and the oil nozzle Different methods.
此外，在上述燃燒裝置中，當由上述空氣噴嘴噴出燃燒用空氣時，可在非燃燒時將燃燒排氣之熱蓄熱於蓄熱部，另一方面在燃燒時將燃燒用空氣通過如此經蓄熱之蓄熱部而加熱，並由上述空氣噴嘴噴出。如此一來，可利用燃燒排氣的熱而有效率地燃燒燃料氣體或燃料油。Further, in the above-described combustion apparatus, when the combustion air is ejected from the air nozzle, the heat of the combustion exhaust gas can be stored in the heat storage unit during non-combustion, and the combustion air is passed through the heat storage unit during the combustion. The heat accumulating portion is heated and ejected by the air nozzle. In this way, the fuel gas or the fuel oil can be efficiently burned by the heat of the combustion exhaust gas.
此外，在本發明之加熱爐中加熱被處理物時，係使用上述燃燒裝置。Further, when the object to be treated is heated in the heating furnace of the present invention, the above-described combustion apparatus is used.
該發明之燃燒裝置中，係作成在離開空氣噴嘴之不同位置分別設置氣體噴嘴與油噴嘴，並向著由空氣噴嘴噴出之燃燒用空氣而噴出由氣體噴嘴噴出之燃料氣體，另一方面噴出由油噴嘴噴出之燃料油，故燃燒的燃料可在燃料氣體與燃料油間切換，使用燃料氣體與燃料油兩者也可簡單地進行。In the combustion apparatus of the present invention, the gas nozzle and the oil nozzle are provided at different positions apart from the air nozzle, and the fuel gas discharged from the gas nozzle is ejected toward the combustion air blown from the air nozzle, and the fuel gas is ejected on the other hand. Since the fuel oil is ejected from the nozzle, the fuel to be burned can be switched between the fuel gas and the fuel oil, and both the fuel gas and the fuel oil can be easily used.
此外，燃燒燃料氣體與燃料油兩者時，將燃料氣體與燃料油在不同位置與燃燒用空氣接觸並燃燒，會抑制燃料油之不完全燃燒，也可防止因不完全燃燒所產生的煙灰附著於油噴嘴。Further, when both the fuel gas and the fuel oil are burned, the fuel gas and the fuel oil are brought into contact with the combustion air at different positions and burned, which suppresses incomplete combustion of the fuel oil, and also prevents soot adhesion due to incomplete combustion. On the oil nozzle.
再者，因在離開空氣噴嘴之不同位置分別設置氣體噴嘴與油噴嘴，故可將氣體噴嘴與油噴嘴分別取下，容易進行修理或維修 等。Furthermore, since the gas nozzle and the oil nozzle are respectively disposed at different positions away from the air nozzle, the gas nozzle and the oil nozzle can be separately removed, which is easy to repair or repair. Wait.

以下根據所附圖式具體地說明本發明之實施形態之燃燒裝置及使用該燃燒裝置之加熱爐。另外，本發明之燃燒裝置及加熱爐係不限於下述實施形態所示者，在不改變發明主旨的範圍內可做適宜改變而實施。Hereinafter, a combustion apparatus according to an embodiment of the present invention and a heating furnace using the same will be specifically described based on the drawings. In addition, the combustion apparatus and the heating furnace of the present invention are not limited to those shown in the following embodiments, and can be modified as appropriate without departing from the scope of the invention.
如第1圖所示，該實施形態中係在加熱爐1的側壁1a處，將燃燒裝置10向著加熱爐1內部而設置。As shown in Fig. 1, in this embodiment, the combustion apparatus 10 is disposed toward the inside of the heating furnace 1 at the side wall 1a of the heating furnace 1.
在此，該燃燒裝置10中係設有將燃燒用空氣噴出於加熱爐1內之空氣噴嘴11，並通過收容有蓄熱材12a之蓄熱部12而將燃燒用空氣導入該空氣噴嘴11。Here, the combustion apparatus 10 is provided with an air nozzle 11 that blows combustion air into the heating furnace 1, and introduces combustion air into the air nozzle 11 through the heat storage unit 12 in which the heat storage material 12a is accommodated.
此外，在離開上述空氣噴嘴11之位置(亦即，與上述空氣噴嘴11相隔之位置)設置將燃料氣體噴出於加熱爐1內之氣體噴嘴13，在該氣體噴嘴13內裝設有氣體噴嘴單元14，係將燃料氣體向著由空氣噴嘴11噴出之燃燒用空氣而噴出，並在將燃料氣體供給於該氣體噴嘴單元14之燃料氣體供給通路15中，設置作為燃料氣體調整裝置之燃料氣體調整閥15a，係調整供給於該氣體噴嘴單元14之燃料氣體的量。此外，在該氣體噴嘴單元14旁邊設置導燃器14a，係用以將由氣體噴嘴單元14噴出之燃料氣體點火。Further, a gas nozzle 13 for spraying fuel gas into the heating furnace 1 is disposed at a position apart from the air nozzle 11 (i.e., at a position spaced apart from the air nozzle 11), and a gas nozzle unit is disposed in the gas nozzle 13 14. The fuel gas is ejected toward the combustion air blown by the air nozzle 11, and the fuel gas is supplied to the fuel gas supply passage 15 of the gas nozzle unit 14 to provide a fuel gas regulating valve as a fuel gas adjusting device. 15a, the amount of fuel gas supplied to the gas nozzle unit 14 is adjusted. Further, a pilot burner 14a is provided beside the gas nozzle unit 14 for igniting the fuel gas ejected by the gas nozzle unit 14.
此外，在與上述空氣噴嘴11相隔之位置中，在與上述氣體噴嘴13相異位置處設置有將燃料油噴出於加熱爐1內之油噴嘴16，在該油噴嘴16內裝設有油噴嘴單元17，係將燃料油向著由空氣噴嘴11噴出之燃燒用空氣而噴出，並在將燃料油供給於該油噴嘴 單元17之燃料油供給通路18中，設置作為燃料油調整裝置之燃料油調整閥18a，係調整供給於該油噴嘴單元17之燃料油的量。此外，在該油噴嘴單元17旁邊設置導燃器17a，係用以將由該油噴嘴單元17噴出之燃料油點火。Further, in a position spaced apart from the air nozzle 11, an oil nozzle 16 for spraying fuel oil into the heating furnace 1 is provided at a position different from the gas nozzle 13, and an oil nozzle is installed in the oil nozzle 16. The unit 17 discharges the fuel oil toward the combustion air blown by the air nozzle 11, and supplies the fuel oil to the oil nozzle.

Further, a pilot burner 17a is provided beside the oil nozzle unit 17 for igniting the fuel oil discharged from the oil nozzle unit 17.
在此，該燃燒裝置10中，僅使用燃料氣體而進行燃燒時，如第2圖所示，打開上述燃料氣體調整閥15a，並通過燃料氣體供給通路15而將燃料氣體導入氣體噴嘴單元14，另一方面關閉上述燃料油調整閥18a，而使燃料油不導入油噴嘴單元17。Here, in the combustion apparatus 10, when the combustion is performed using only the fuel gas, as shown in FIG. 2, the fuel gas adjustment valve 15a is opened, and the fuel gas is introduced into the gas nozzle unit 14 through the fuel gas supply passage 15. On the other hand, the fuel oil regulating valve 18a is closed, and the fuel oil is not introduced into the oil nozzle unit 17.
接著，在非燃燒時，將燃燒用空氣通過將燃燒排氣的熱蓄熱於蓄熱材12a之蓄熱部12而導入上述空氣噴嘴11，將在該蓄熱部12中經加熱之燃燒用空氣由空氣噴嘴11向加熱爐1內噴出，並如上述由導引燃料氣體之氣體噴嘴單元14，將燃料氣體向著噴出於加熱爐1內之燃燒用空氣而噴出，並將該燃料氣體在加熱爐1內燃燒。另外，於加熱爐1內之溫度未達燃料氣體之點火溫度時，藉由上述導燃器14a而將由氣體噴嘴單元14噴出之燃料氣體點火。Then, at the time of non-combustion, the combustion air is introduced into the air nozzle 11 by storing the heat of the combustion exhaust gas in the heat storage unit 12 of the heat storage material 12a, and the combustion air heated in the heat storage unit 12 is used by the air nozzle. 11 is ejected into the heating furnace 1, and the fuel gas is sprayed toward the combustion air sprayed into the heating furnace 1 by the gas nozzle unit 14 for guiding the fuel gas as described above, and the fuel gas is burned in the heating furnace 1. . Further, when the temperature in the heating furnace 1 is less than the ignition temperature of the fuel gas, the fuel gas discharged from the gas nozzle unit 14 is ignited by the pilot burner 14a.
另一方面，該燃燒裝置10中，僅使用燃料油而進行燃燒時，如第3圖所示，打開上述燃料油調整閥18a，並通過燃料油供給通路18而將燃料油導入油噴嘴單元17，另一方面關閉上述燃料氣體調整閥15a，而使燃料氣體不導入氣體噴嘴單元14。On the other hand, in the combustion apparatus 10, when the combustion is performed using only the fuel oil, as shown in Fig. 3, the fuel oil adjustment valve 18a is opened, and the fuel oil is supplied to the oil nozzle unit 17 through the fuel oil supply passage 18. On the other hand, the fuel gas regulating valve 15a is closed, and the fuel gas is not introduced into the gas nozzle unit 14.
接著，與上述燃料氣體時同樣地，將燃燒用空氣通過蓄熱部12而導入空氣噴嘴11，將在該蓄熱部12中經加熱之燃燒用空氣由該空氣噴嘴11噴出於加熱爐1內，並如上述由導引燃料油之油噴嘴單元17，將燃料油向著噴出於加熱爐1內之燃燒用空氣而噴 出，並將該燃料油在加熱爐1內燃燒。另外，加熱爐1內之溫度未達燃料油之點火溫度時，藉由上述導燃器17a而將由油噴嘴單元17噴出之燃料油點火。Then, similarly to the case of the fuel gas, the combustion air is introduced into the air nozzle 11 through the heat storage unit 12, and the combustion air heated in the heat storage unit 12 is sprayed into the heating furnace 1 by the air nozzle 11, and The fuel oil nozzle unit 17 for guiding the fuel oil is sprayed toward the combustion air sprayed into the heating furnace 1 as described above. The fuel oil is burned in the heating furnace 1. Further, when the temperature in the heating furnace 1 does not reach the ignition temperature of the fuel oil, the fuel oil discharged from the oil nozzle unit 17 is ignited by the pilot burner 17a.
如此一來，可簡單地將在該燃燒裝置10中燃燒所使用之燃料在燃料氣體與燃料油間切換。In this way, the fuel used for combustion in the combustion apparatus 10 can be simply switched between the fuel gas and the fuel oil.
此外，該燃燒裝置10中，使用燃料氣體與燃料油兩者而進行燃燒時，如第4圖所示，打開上述燃料氣體調整閥15a與燃料油調整閥18a，通過燃料氣體供給通路15而將燃料氣體導入氣體噴嘴單元14，並通過燃料油供給通路18而將燃料油導入油噴嘴單元17。Further, when the combustion device 10 performs combustion using both the fuel gas and the fuel oil, as shown in FIG. 4, the fuel gas adjustment valve 15a and the fuel oil adjustment valve 18a are opened, and the fuel gas supply passage 15 is used. The fuel gas is introduced into the gas nozzle unit 14, and the fuel oil is introduced into the oil nozzle unit 17 through the fuel oil supply passage 18.
接著，與上述燃料氣體或燃料油時相同地，將燃燒用氣體通過上述蓄熱部12而導入空氣噴嘴11，將在該蓄熱部12中經加熱之燃燒用空氣由該空氣噴嘴11噴出於加熱爐1內，並如上述由導引燃料氣體之氣體噴嘴單元14、及導引燃料油之油噴嘴單元17，分別將燃料氣體與燃料油向著噴出於加熱爐1內之燃燒用空氣而噴出，並將該燃料氣體與燃料油在加熱爐1內燃燒。Then, similarly to the case of the fuel gas or the fuel oil, the combustion gas is introduced into the air nozzle 11 through the heat storage unit 12, and the combustion air heated in the heat storage unit 12 is sprayed from the air nozzle 11 to the heating furnace. In the above, the fuel gas nozzle unit 14 for guiding the fuel gas and the oil nozzle unit 17 for guiding the fuel oil are respectively sprayed toward the combustion air sprayed into the heating furnace 1 by the fuel nozzle unit 14 for guiding the fuel gas, and The fuel gas and the fuel oil are burned in the heating furnace 1.
在此，於上述燃燒裝置10中，設成不使由油噴嘴單元17噴出之燃料油在加熱爐1內單獨地燃燒，而是一直與由氣體噴嘴單元14噴出之燃料氣體一起燃燒時，可刪除該油噴嘴單元17之導燃器17a等。此外，在燃料油之點火溫度以上之情形下，才噴出燃料油時亦可刪除該油噴嘴單元17之上述導燃器17a等。Here, in the above-described combustion apparatus 10, the fuel oil discharged from the oil nozzle unit 17 is not separately burned in the heating furnace 1, but is always burned together with the fuel gas discharged from the gas nozzle unit 14. The pilot burner 17a of the oil nozzle unit 17 and the like are deleted. Further, in the case where the fuel oil is fired or higher, the pilot burner 17a of the oil nozzle unit 17 or the like may be deleted when the fuel oil is discharged.
此外，如上述於使用燃料氣體與燃料油兩者而進行燃燒時，藉由燃料氣體調整閥15a與燃料油調整閥18a，而可適當地調整導入氣體噴嘴單元14之燃料氣體的量、與導入油噴嘴單元17之燃 料油的量。Further, when the combustion is performed using both the fuel gas and the fuel oil, the fuel gas adjustment valve 15a and the fuel oil adjustment valve 18a can appropriately adjust the amount and introduction of the fuel gas introduced into the gas nozzle unit 14. Fuel nozzle unit 17 The amount of oil.
接著，調查固定上述燃燒裝置10之燃料的燃燒量，並改變導入氣體噴嘴單元14之燃料氣體之比例、與導入油噴嘴單元17之燃料油之比例時之NOx產生量與焰長之變化，其結果示於第5圖及第6圖。Next, the amount of combustion of the fuel to which the combustion apparatus 10 is fixed is measured, and the change in the ratio of the amount of the fuel gas introduced into the gas nozzle unit 14 to the ratio of the fuel oil introduced into the oil nozzle unit 17 to the change in the NOx generation amount and the flame length is examined. The results are shown in Figures 5 and 6.
在此，第5圖中係顯示使僅燃燒燃料油時之NOx產生量為1.00，而改變燃料油與燃料氣體之比例時其NOx之產生量的變化。Here, Fig. 5 shows a change in the amount of NOx generated when the amount of NOx generated when only the fuel oil is burned is 1.00, and the ratio of the fuel oil to the fuel gas is changed.
此外，第6圖中係顯示使僅燃燒燃料油時之火焰長為1.00，而改變燃料油與燃料氣體之比例時其火焰長的變化。Further, Fig. 6 shows the change in the flame length when the flame length when burning only the fuel oil is 1.00 and the ratio of the fuel oil to the fuel gas is changed.
結果可知，若導入於油噴嘴單元17之燃料油的比例越高，則NOx產生量增加，另一方面火焰長變長且即使在離開燃燒裝置10之位置也可進行充分之加熱。此外，若燃料油之比例變高，則燃料油燃燒之火焰其輻射傳熱變高，可有效率地加熱加熱爐1內之被處理物(未圖示)。As a result, it is understood that the higher the proportion of the fuel oil introduced into the oil nozzle unit 17, the higher the amount of NOx generated, and the longer the flame length, and the sufficient heating can be performed even at a position away from the combustion apparatus 10. Further, when the ratio of the fuel oil is increased, the flame of the fuel oil combustion is increased in radiation heat, and the workpiece (not shown) in the heating furnace 1 can be efficiently heated.
如此，使用燃料氣體與燃料油兩者進行燃燒時，可依所需之火焰長或溫度而決定燃料油的比例，除此之外，也可依燃料氣體與燃料油之時價或NOx之產生量而決定，藉由調整該比例可有助於低成本、低公害之燃燒。In this way, when both the fuel gas and the fuel oil are used for combustion, the ratio of the fuel oil can be determined according to the required flame length or temperature, and in addition, the price of the fuel gas and the fuel oil or the generation of NOx can be used. The amount is determined by adjusting the ratio to contribute to low-cost, low-polluting combustion.
此外，如上述由氣體噴嘴單元14與油噴嘴單元17將燃料氣體與燃料油，分別向著由空氣噴嘴11噴出之燃燒用空氣噴出，並在加熱爐1內燃燒燃料氣體與燃料油時，若在較由氣體噴嘴單元14噴出之燃料氣體的位置更向噴出方向下游側之位置，將由油噴嘴單元17噴出之燃料油與由空氣噴嘴11噴出之燃燒用空氣合流，則易燃燒之燃料氣體會先燃燒，且不易燃燒之燃料油會隨後 燃燒，故會使燃燒時的火焰長更長，在加熱爐1內廣範圍地進行燃燒並均勻地加熱加熱爐1內。Further, when the fuel gas and the fuel oil are respectively ejected from the combustion air blown by the air nozzle 11 by the gas nozzle unit 14 and the oil nozzle unit 17, and the fuel gas and the fuel oil are burned in the heating furnace 1, if The position of the fuel gas ejected from the gas nozzle unit 14 is further toward the downstream side in the discharge direction, and the fuel oil ejected from the oil nozzle unit 17 merges with the combustion air ejected from the air nozzle 11, and the combustible fuel gas first Burning, non-flammable fuel oil will follow When it is burned, the flame length during combustion is made longer, and combustion is widely performed in the heating furnace 1 and uniformly heated in the heating furnace 1.
而且，如此在較由氣體噴嘴單元14噴出之燃料氣體的位置更向噴出方向下游側之位置，將由油噴嘴單元17噴出之燃料油與由空氣噴嘴11噴出之燃燒用空氣合流時，例如可使用第7圖或第8圖所示之方法。Further, when the position of the fuel gas ejected from the gas nozzle unit 14 is further toward the downstream side in the discharge direction, when the fuel oil discharged from the oil nozzle unit 17 and the combustion air discharged from the air nozzle 11 are merged, for example, it can be used. The method shown in Figure 7 or Figure 8.
在此，第7圖所示之方法中，空氣噴嘴11與氣體噴嘴13之間隔d1、以及空氣噴嘴11與油噴嘴16之間隔d2設為相同，另一方面，向著由空氣噴嘴11噴出之燃燒用空氣，由氣體噴嘴13噴出燃料氣體之燃料氣體噴出角度θ 1，亦即空氣噴嘴11之軸線L1與氣體噴嘴13之軸線L2交叉之角度；向著由空氣噴嘴11噴出之燃燒用空氣，由油噴嘴16噴出燃料油之燃料油噴出角度θ 2，亦即空氣噴嘴11之軸線L1與油噴嘴16之軸線L3交叉之角度，兩者相較θ 2較θ 1小。Here, in the method shown in Fig. 7, the interval d1 between the air nozzle 11 and the gas nozzle 13 and the interval d2 between the air nozzle 11 and the oil nozzle 16 are the same, and on the other hand, the combustion is performed toward the air nozzle 11. The fuel gas discharge angle θ1 from which the fuel gas is ejected by the gas nozzle 13 is an angle at which the axis L1 of the air nozzle 11 intersects with the axis L2 of the gas nozzle 13; the combustion air ejected from the air nozzle 11 is made of oil. The nozzle 16 discharges the fuel oil discharge angle θ 2 of the fuel oil, that is, the angle at which the axis L1 of the air nozzle 11 intersects the axis L3 of the oil nozzle 16 , which is smaller than θ 2 than θ 1 .
此外，第8圖所示方法中，空氣噴嘴11與油噴嘴16之間隔d2大於空氣噴嘴11與氣體噴嘴13之間隔d1，另一方面，向著由空氣噴嘴11噴出之燃燒用空氣，由氣體噴嘴13噴出燃料氣體之燃料氣體噴出角度θ 1、與由油噴嘴16噴出燃料油之燃料油噴出角度θ 2相同。Further, in the method shown in Fig. 8, the interval d2 between the air nozzle 11 and the oil nozzle 16 is larger than the interval d1 between the air nozzle 11 and the gas nozzle 13, and on the other hand, the combustion air discharged from the air nozzle 11 is supplied by the gas nozzle. The fuel gas discharge angle θ 1 at which the fuel gas is discharged is the same as the fuel oil discharge angle θ 2 at which the fuel oil is discharged from the oil nozzle 16 .
此外，雖然圖中未顯示但可組合第7圖所示方法與第8圖所示方法，而作成為在較由氣體噴嘴單元14噴出之燃料氣體的位置更向噴出方向下游側之位置，將由油噴嘴單元17噴出之燃料油與由空氣噴嘴11噴出之燃燒用空氣合流。Further, although not shown in the drawings, the method shown in Fig. 7 and the method shown in Fig. 8 may be combined, and the position on the downstream side in the discharge direction from the position of the fuel gas ejected from the gas nozzle unit 14 will be The fuel oil discharged from the oil nozzle unit 17 merges with the combustion air jetted from the air nozzle 11.
此外，與上述情形相反，亦可設成在較由氣體噴嘴單元14噴 出之燃料氣體的位置更向噴出方向上游側之位置，將由油噴嘴單元17噴出之燃料油與由空氣噴嘴11噴出之燃燒用空氣合流。如此一來，因難燃燒之燃料油先與燃燒用空氣混合，故可抑制燃料油不完全燃燒，並防止煙灰產生。In addition, contrary to the above, it may be arranged to be sprayed by the gas nozzle unit 14 The position of the fuel gas is further increased to the upstream side in the discharge direction, and the fuel oil discharged from the oil nozzle unit 17 merges with the combustion air discharged from the air nozzle 11. In this way, since the fuel oil that is difficult to burn is first mixed with the combustion air, it is possible to suppress incomplete combustion of the fuel oil and prevent the generation of soot.
另外，上述實施形態中，雖然說明的是具有蓄熱燃燒排氣的熱之蓄熱部12的蓄熱式燃燒裝置10，但不具有如此蓄熱裝置12之通常燃燒裝置也可同樣地構成。Further, in the above-described embodiment, the regenerative combustion apparatus 10 having the heat storage unit 12 for accumulating the combustion exhaust gas is described. However, the normal combustion apparatus having no such heat storage unit 12 may be configured in the same manner.
