Description

燃燒器裝置及加熱處理設備 Burner device and heat treatment equipment

本發明係有關燃燒器裝置及使用該燃燒器裝置的加熱處理設備，該燃燒器裝置係於空氣供應管之內周側設置有燃料氣體供應管，且使通過燃料氣體供應管而被導引的燃料氣體與通過前述的空氣供應管而被導引至燃料氣體供應管之外周側的空氣混合來進行燃燒。特別是，前述燃燒器裝置即使於減少了通過燃料氣體供應管而被導引的燃料氣體的量的情形下，也能使前述的燃料氣體與通過氣體供應管而被導引至燃料氣體供應管之外周側的空氣適切地混合而適切地保持火焰，能夠提高燃燒器的調節比(turndown ratio以完全燃燒之燃料氣體與空氣之比值混合燃料氣體與空氣之混合氣體供應量之變化比值)。 The present invention relates to a burner device and a heat treatment device using the burner device. The burner device is provided with a fuel gas supply pipe on the inner peripheral side of an air supply pipe and is guided through the fuel gas supply pipe The fuel gas is mixed with the air guided to the outer peripheral side of the fuel gas supply pipe through the aforementioned air supply pipe to be combusted. In particular, even when the amount of fuel gas guided through the fuel gas supply pipe is reduced, the aforementioned burner device can cause the aforementioned fuel gas and the gas supply pipe to be guided to the fuel gas supply pipe. The air on the outer peripheral side is appropriately mixed and the flame is maintained appropriately, which can increase the turndown ratio of the burner (turndown ratio is the ratio of the change in the supply amount of the mixed gas of the fuel gas to the air mixed with the ratio of the completely burned fuel gas to the air).

以往，於工業用爐等加熱處理設備中，乃廣泛利用燃燒器裝置，該燃燒器裝置係在空氣供應管之內周側設置有燃料氣體供應管，且使通過燃料氣體供應管而被導引的燃料氣體與通過前述的空氣供應管而被導引至燃料氣體供應管之外周側的空氣混合來進行燃燒。 In the past, in industrial furnaces and other heat treatment equipment, burner devices are widely used. The burner device is equipped with a fuel gas supply pipe on the inner peripheral side of the air supply pipe and is guided through the fuel gas supply pipe. The fuel gas is mixed with the air guided to the outer periphery of the fuel gas supply pipe through the aforementioned air supply pipe to be combusted.

在此，於上述之燃燒器裝置中，一般而言，一旦將通過燃料氣體供應管而被導引的燃料氣體的量或通過空氣供應管而被導引至燃料氣體供應管之外周側之空氣的量減少，前述的燃料氣體與空氣就無法被充分地混合而變得無法保持火焰，且變得無法繼續燃燒，因此，存在有無法確保較大的調節比等問題。 Here, in the above-mentioned burner device, generally speaking, once the amount of fuel gas guided through the fuel gas supply pipe or the air guided to the outer periphery of the fuel gas supply pipe through the air supply pipe If the amount of fuel gas is reduced, the aforementioned fuel gas and air cannot be sufficiently mixed, and the flame cannot be maintained, and the combustion cannot be continued. Therefore, there is a problem that a large turndown ratio cannot be ensured.

因此，以往為了對付如前述那般的燃燒器裝置中的火焰消滅的情況，乃進行了於燃燒器裝置設置引燃器(pilot burner)或電點火裝置。 Therefore, in the past, in order to cope with the flame extinction in a burner device as described above, a pilot burner or an electric ignition device has been installed in the burner device.

然而，如此地設置引燃器的情形時，就必須有另外供應燃料氣體等至該引燃器之設備等，因此存在有成本提高並且裝置大型化等問題。 However, when the pilot burner is installed in this way, it is necessary to separately supply the fuel gas and other equipment to the pilot burner. Therefore, there are problems such as increased cost and increased size of the device.

再者，以往如專利文獻1所示，係揭示有以下述方式所建構的構成：對於有由燃料氣體與空氣混合成的混合氣體被供應至前端側之燃燒器本體部的前端部，在以朝前端側突出成錐狀的方式所設置之噴出孔穴形成部的中央部設置主噴出孔，並且於形成錐狀之傾斜部分設置保持火焰形成用孔，而且於前述噴出孔穴形成部的外側方設置比噴出孔穴形成部更朝前端側突出之筒狀的保護部，使從保持火焰形成用孔噴出的前述混合氣體在保護部內燃燒。 Furthermore, as shown in Patent Document 1, conventionally, as shown in Patent Document 1, there is disclosed a structure constructed in such a way that a mixed gas of fuel gas and air is supplied to the front end of the burner main body on the front end side. The main ejection hole is provided in the central part of the ejection hole forming part protruding in a tapered shape toward the tip side, and a flame-holding hole is provided in the tapered inclined part, and is provided outside the ejection hole forming part The cylindrical protective part protruding further toward the tip side than the ejection hole forming part burns the above-mentioned mixed gas ejected from the flame holding hole forming part in the protective part.

然而，專利文獻1所示者，由於係將由燃料氣體與空氣預先混合成的混合氣體導引至設置在燃燒器本體部之前端部的噴出孔穴形成部，且使從設置在該噴出 孔穴形成部的傾斜部分的保持火焰形成用孔噴出的混合氣體在保護部內燃燒者，所以存在有當減少混合氣體中的燃料氣體的量時難以使混合氣體穩定燃燒的問題。 However, as shown in Patent Document 1, because the mixed gas pre-mixed with fuel gas and air is guided to the ejection hole forming portion provided at the front end of the burner body, and the ejection hole forming portion is provided The inclined part of the flame-forming hole keeps the mixed gas ejected from burning in the protective part, so there is a problem that it is difficult to stably burn the mixed gas when the amount of fuel gas in the mixed gas is reduced.

此外，專利文獻2揭示有下述構成：於將噴射燃料之通過口設成開口之倒圓錐狀之本體的周壁全面，將朝向相反方向而使燃燒用空氣分別朝向前方回旋噴氣之多數個前部細縫與後部細縫隔著間隔於前後成為兩段地朝輻射方向開口並且使後部細縫開口至通過口。 In addition, Patent Document 2 discloses a configuration in which the entire surface of the peripheral wall of the main body in the shape of an inverted cone in which the fuel injection port is opened is directed in the opposite direction so that the combustion air is directed to the front part of the swirling jet. The sipe and the rear sipe are opened in two stages from the front and back to the radiation direction with an interval therebetween, and the rear sipe is opened to the passage opening.

然而，專利文獻2所揭示者，由於係使噴射燃料之通過口於倒圓錐狀之本體的中央部開口，而僅使燃料從該中央部的通過口噴射，所以在減少了噴射的燃料的量時，從中央部之通過口噴射的燃料不一定會與從前部細縫或後部細縫朝向前方回旋噴氣的燃燒用空氣充分地接觸而燃燒，而仍然存有在減少了噴射的燃料時難以確實地保持火焰的問題。 However, as disclosed in Patent Document 2, the fuel injection port is opened at the center of the inverted cone-shaped body, and only the fuel is injected from the center port. Therefore, the amount of fuel injected is reduced. At this time, the fuel injected from the central port does not necessarily come into full contact with the combustion air that swirls forward from the front slit or the rear slit to burn. However, it is difficult to be sure if the injected fuel is reduced. The problem of keeping the flames in place.

再者，於專利文獻3、4中也提出有：以使供應的燃料的量改變而能夠進行在較寬廣範圍的燃燒之符合高調節比之方式所建構成的燃燒器。 In addition, Patent Documents 3 and 4 also propose combustors constructed in a manner that allows combustion in a wide range by changing the amount of fuel to be supplied and in accordance with a high turndown ratio.

但是，專利文獻3、4所揭示者，也仍然存有在減少了噴射的燃料時難以確實地保持火焰的問題。 However, as disclosed in Patent Documents 3 and 4, there is still a problem that it is difficult to reliably maintain the flame when the injected fuel is reduced.

此外，專利文獻5所揭示之熱處理裝置，係於燃燒器裝置的附近設置收納有蓄熱材之一對的蓄熱室，於一方的蓄熱室，進行將藉由收納在該蓄熱室之蓄熱材所蓄熱之熱所加熱後的燃燒用空氣，朝向從前述燃燒器 裝置中的燃料氣體供應管噴出的燃料氣體噴射而使燃料氣體燃燒的動作，另一方面，於另一方的蓄熱室，進行使燃燒燃料氣體後產生的燃燒排放氣體被收納在該蓄熱室之蓄熱材吸取而使蓄熱材蓄熱的動作，且交互地切換前述一方的蓄熱室與另一方的蓄熱室的動作，在該加熱處理裝置中，由於切換燃燒用空氣的噴射與吸取之切換閥的開閉動作時間為數秒鐘，空氣的流動於此期間呈不穩定，所以以往會阻斷燃料氣體的供應而將火焰消滅。因此，必須設置引燃器或電點火裝置等點火裝置而於每次切換燃燒用空氣時再度點火，而存在有燃料裝置之構造或控制變得複雜等問題。此外，由於一旦火焰消滅就不易保持燃燒器裝置近旁之環境氣體的溫度，所以也成為爐內溫度變動的主要因素。 In addition, in the heat treatment device disclosed in Patent Document 5, a heat storage chamber containing a pair of heat storage materials is installed in the vicinity of the burner device, and one heat storage chamber is used to store heat by the heat storage material stored in the heat storage chamber. The combustion air heated by the heat is injected toward the fuel gas ejected from the fuel gas supply pipe in the burner device to burn the fuel gas. On the other hand, it burns the fuel in the other regenerator. The combustion exhaust gas generated after the gas is absorbed by the heat storage material contained in the regenerator to accumulate heat, and the operation of one of the regenerators and the other regenerator is alternately switched. In the heating treatment device, Since the opening and closing operation time of the switching valve for switching between the injection and suction of combustion air is several seconds, the flow of air is unstable during this period, so in the past, the supply of fuel gas was blocked and the flame was extinguished. Therefore, it is necessary to install an ignition device such as a pilot burner or an electric ignition device to re-ignite each time the combustion air is switched, and there is a problem that the structure or control of the fuel device becomes complicated. In addition, once the flame is extinguished, it is difficult to maintain the temperature of the ambient gas near the burner device, which also becomes a major factor in temperature fluctuations in the furnace.

本發明以解決燃燒器裝置中的前述的問題作為課題者。 The present invention aims to solve the aforementioned problems in the burner device.

特別是，係以下列的情形為課題者：於空氣供應管之內周側設置有燃料氣體供應管，且使通過燃料氣體供應管而被導引的燃料氣體與通過前述空氣供應管而被導引至燃料氣體供應管之外周側的空氣混合並燃燒的燃燒器裝置中，即使在減少了通過燃料氣體供應管而被導引之燃料氣體的量的情形下，亦能將前述燃料氣體與通過空氣供應管而被導引至燃料氣體供應管之外周側的空氣適切地混合而適切地保持火焰，並提高燃燒器的調節比。 In particular, the following situation is the subject: a fuel gas supply pipe is provided on the inner peripheral side of the air supply pipe, and the fuel gas guided through the fuel gas supply pipe is guided through the air supply pipe. In the combustor device in which the air introduced to the outer periphery of the fuel gas supply pipe is mixed and burned, even when the amount of fuel gas introduced through the fuel gas supply pipe is reduced, the fuel gas can be combined with the passing The air that is guided to the outer periphery of the fuel gas supply pipe through the air supply pipe is appropriately mixed to appropriately maintain the flame, and the turndown ratio of the burner is improved.

為解決上述課題，本發明之燃燒器裝置，係於空氣供應管之內周側設置有燃料氣體供應管，且使通過燃料氣體供應管而被導引的燃料氣體與通過前述空氣供應管而被導引至燃料氣體供應管之外周側的空氣混合並燃燒者，其中，於設置在前述空氣供應管之內周側之前述燃料氣體供應管的前端設置有朝向前方並往外周側擴大成錐狀的火焰保持筒，且於該火焰保持筒設置有：空氣導入孔，將通過前述空氣供應管而被導引至燃料氣體供應管之外周側的空氣導引至火焰保持筒內；以及空氣導引部，以於該空氣導入孔的部分朝空氣之流動的上游側往火焰保持筒的外周側突出的方式形成，而將空氣從前述空氣供應管導引至前述空氣導入孔；於前述燃料氣體供應管的前端部設置有：主噴射口，使通過燃料氣體供應管而被導引的燃料氣體從燃料氣體供 應管的中央部噴出；以及複數個副噴射口，使該燃料氣體從前述主噴射口的周圍噴出；將前述主噴射口設置成比前述複數個副噴射口更朝前端側突出，並於該主噴射口之周圍設置有將從前述各副噴射口噴出的燃料氣體予以導引的導引部，且將前述複數個副噴射口以朝向燃料氣體供應管的外周側的方式傾斜設置；而且該燃燒器裝置還設置有：控制裝置，控制供應至前述燃料氣體供應管之燃料氣體的量及/或供應至空氣供應管之空氣的量。 In order to solve the above-mentioned problems, the burner device of the present invention is provided with a fuel gas supply pipe on the inner peripheral side of the air supply pipe, and the fuel gas guided through the fuel gas supply pipe is passed through the air supply pipe. The air that is guided to the outer circumference of the fuel gas supply pipe is mixed and burned, wherein the front end of the fuel gas supply pipe provided on the inner circumference of the air supply pipe is provided with a tapered shape facing forward and expanding toward the outer circumference. The flame holding cylinder is provided with: an air introduction hole to guide the air guided to the outer circumference of the fuel gas supply pipe through the aforementioned air supply pipe into the flame holding cylinder; and air guide The part is formed in such a way that the part of the air introduction hole protrudes toward the outer peripheral side of the flame holding cylinder toward the upstream side of the air flow, and guides the air from the air supply pipe to the air introduction hole; in the fuel gas supply The front end of the pipe is provided with a main injection port that allows the fuel gas guided through the fuel gas supply pipe to be supplied from the fuel gas The central part of the pipe should be ejected; and a plurality of auxiliary injection ports to eject the fuel gas from the periphery of the main injection port; the main injection port is set to protrude toward the front end side than the plurality of auxiliary injection ports, and the The main injection port is provided with a guide portion that guides the fuel gas ejected from the aforementioned sub-injection ports, and the plurality of sub-injection ports are arranged obliquely toward the outer peripheral side of the fuel gas supply pipe; and The burner device is also provided with a control device that controls the amount of fuel gas supplied to the fuel gas supply pipe and/or the amount of air supplied to the air supply pipe.

再者，本發明之燃燒器裝置係建構成：使通過燃料氣體供應管而被導引的燃燒氣體從燃料氣體供應管之前端部的中央部的主噴射口、及設置在該主噴射口之周圍的複數個副噴射口噴出，並且藉由於前述燃料氣體供應管之前端朝向前方並往外周側擴大成錐狀的火焰保持筒所設置之前述空氣導引部，使通過空氣供應管而被導引至燃料氣體供應管之外周側的空氣通過設置在火焰保持筒之前述空氣導入孔而導引至火焰保持筒內。依據如此的構成，即使在減少了通過燃料氣體供應管而被導引之燃料氣體的量的情形下，燃料氣體除了從前述主噴射口噴出之外也會從設置在主噴射口的周圍之複數個副噴射口噴出，且從複數個副噴射口噴出的燃料氣體會沿著錐形流動，而與藉由設置在前述火焰保持筒之空氣導引部從前述空氣供應管通過空氣導入孔被導引至火焰保持筒內的空氣充分地混合而燃燒，以穩定地保持火焰。 Furthermore, the combustor device of the present invention is constructed such that the combustion gas guided through the fuel gas supply pipe flows from the main injection port at the center of the front end of the fuel gas supply pipe, and the main injection port A plurality of sub-injection ports around the jets are ejected, and the air guide portion provided by the flame holding tube whose front end of the fuel gas supply pipe faces forward and expands to the outer circumference side into a cone shape is guided through the air supply pipe. The air introduced to the outer peripheral side of the fuel gas supply pipe is introduced into the flame holding cylinder through the aforementioned air introduction hole provided in the flame holding cylinder. According to such a configuration, even when the amount of fuel gas guided through the fuel gas supply pipe is reduced, the fuel gas will be ejected from the main injection port in addition to the aforesaid main injection port. The fuel gas ejected from the sub-injection ports, and the fuel gas ejected from the plurality of sub-injection ports flows in a conical shape, and is guided from the air supply pipe through the air introduction hole by the air guide portion provided in the flame holder. The air introduced into the flame holding cylinder is fully mixed and burned to maintain the flame stably.

再者，由於空氣導入孔係相對於空氣的流動為斜向的細縫，且空氣導引部朝空氣之流動的上游側突出，所以能夠將空氣的流動大幅地承接朝斜向回旋而引導至火焰保持筒內，並且藉由其攪拌效果來更為促進其與燃料氣體的混合。 Furthermore, since the air introduction holes are slits obliquely with respect to the flow of air, and the air guide portion protrudes toward the upstream side of the flow of air, the flow of air can be largely swiveled in the oblique direction and guided to it. The flame is kept in the cylinder, and its mixing effect with the fuel gas is further promoted.

此外，本發明之燃燒器裝置較佳為：將使燃料氣體從前述燃料氣體供應管之中央部噴出的主噴射口設置成比使燃料氣體從該主噴射口的周圍噴出之複數個副噴射口更朝前端側突出，並設置有於將從該主噴射口之周圍的各副噴射口噴出的燃料氣體予以導引的導引部。依據如此的構成，即使在減少了通過燃料氣體供應管而被導引之燃料氣體的量的情形下，從主噴射口之周圍的各副噴射口噴出的燃料氣體也不會受到外部的影響即能通過前述的導引部，且適切地被導引至從空氣導入孔被導引至火焰保持筒內之空氣的位置而與該空氣充分地混合以保持火焰。 In addition, in the burner device of the present invention, it is preferable that the main injection port through which the fuel gas is ejected from the central portion of the fuel gas supply pipe is set to be larger than the plurality of auxiliary injection ports through which the fuel gas is ejected from the periphery of the main injection port It further protrudes toward the front end side, and is provided with a guide portion that guides the fuel gas ejected from each sub-injection port around the main injection port. According to such a configuration, even when the amount of fuel gas guided through the fuel gas supply pipe is reduced, the fuel gas ejected from the auxiliary injection ports around the main injection port will not be affected by the outside. It can pass through the aforementioned guide portion and be appropriately guided to a position where the air is guided from the air introduction hole to the flame holding tube, and is sufficiently mixed with the air to maintain the flame.

再者，於本發明之加熱處理設備中係建構成：使用前述那種燃燒器裝置，且藉由前述控制裝置來控制通過燃料氣體供應管而被導引的燃料氣體的量，以控制燃燒而進行加熱處理。 Furthermore, in the heating treatment equipment of the present invention, it is constructed that the aforementioned burner device is used, and the aforementioned control device controls the amount of fuel gas guided through the fuel gas supply pipe to control combustion Carry out heat treatment.

於該加熱處理設備中，藉由前述控制裝置，能夠控制供應至燃料氣體供應管之燃料氣體的量及/或供應至空氣供應管之空氣的量而控制燃料氣體的燃燒，即使在減少了如前述那般通過燃料氣體供應管而被導引之燃料氣體的量的情形下，從主噴射口之周圍的各副噴射口噴出的燃料氣體也會與如前述那般藉由前述空氣導引部從空氣供應管通過空氣導入孔被導引至火焰保持筒內的空氣充分地混合並燃燒而保持火焰，能夠提高燃燒器的調節比而在較寬廣的範圍控制燃料氣體的燃燒。 In the heat treatment equipment, by the aforementioned control device, the amount of fuel gas supplied to the fuel gas supply pipe and/or the amount of air supplied to the air supply pipe can be controlled to control the combustion of the fuel gas, even if such In the case of the amount of fuel gas that is guided through the fuel gas supply pipe as described above, the fuel gas ejected from the sub-injection ports around the main injection port will also be the same as described above by the air guide portion. The air guided from the air supply pipe through the air introduction hole into the flame holding tube is sufficiently mixed and burned to maintain the flame, and the turndown ratio of the burner can be increased to control the combustion of the fuel gas in a wide range.

再者，於本發明之加熱處理設備中，係能夠建構成：於前述燃燒器裝置的附近設置收納有蓄熱材之一對的蓄熱室，於一方的蓄熱室，進行使藉由收納在該蓄熱室之蓄熱材所蓄熱之熱所加熱後的燃燒用空氣，朝向從前述燃燒器裝置中的燃料氣體供應管噴出的燃料氣體噴射而使燃料氣體燃燒的動作，另一方面，於另一方的蓄熱室，進行使燃燒燃料氣體後產生的燃燒排放氣體被吸取至該蓄熱室而使所收納的蓄熱材蓄熱的動作，且交互地切換進行前述一方的蓄熱室與另一方的蓄熱室的動作。 Furthermore, in the heat treatment equipment of the present invention, it can be constructed such that a heat storage chamber containing a pair of heat storage materials is provided near the burner device, and one heat storage chamber is stored in the heat storage chamber. The combustion air heated by the heat stored in the heat storage material in the chamber is injected toward the fuel gas ejected from the fuel gas supply pipe in the burner device to burn the fuel gas.

接著，作為第一加熱處理設備，如第5圖(A)、(B)所示，說明將前述燃燒器裝置10使用於工業用爐 20的情形。 Next, as the first heat treatment facility, as shown in Figs. 5 (A) and (B), a case where the aforementioned burner device 10 is used in an industrial furnace 20 will be described.

在此，於該工業用爐20中，係建構成：以貫穿其爐壁21的方式安裝前述燃燒器裝置10的前端部，藉由前述控制裝置Z來控制藉由燃料氣體供應裝置Y從燃料氣體導入部12a供應至燃料氣體供應管12內的燃料氣體，並且控制藉由空氣供應裝置X從空氣導入部11a供應至空氣供應管11內之空氣的量。 Here, in the industrial furnace 20, the system is constructed such that the front end of the burner device 10 is installed through the furnace wall 21, and the fuel gas supply device Y is controlled by the fuel gas supply device Y by the control device Z.

再而，如第5圖(A)所示，於前述燃燒器裝置10中，當增大工業用爐20內的燃料氣體的燃燒量時，係增多供應至燃料氣體供應管12之燃料氣體的量及供應至空氣供應管11之空氣的量，以使火焰增大而增大燃燒量。 Furthermore, as shown in Fig. 5(A), in the aforementioned burner device 10, when the combustion amount of the fuel gas in the industrial furnace 20 is increased, the amount of fuel gas supplied to the fuel gas supply pipe 12 is increased. And the amount of air supplied to the air supply pipe 11 to increase the flame and increase the amount of combustion.

另一方面，如第5圖(B)所示，於前述燃燒器裝置10中，當減少工業用爐20內的燃料氣體的燃燒量時，係減少供應至燃料氣體供應管12之燃料氣體的量及供應至空氣供應管11之空氣的量，使火焰縮減而減少燃燒量。 On the other hand, as shown in Fig. 5(B), in the aforementioned burner device 10, when the combustion amount of the fuel gas in the industrial furnace 20 is reduced, the amount of fuel gas supplied to the fuel gas supply pipe 12 is reduced. The amount and the amount of air supplied to the air supply pipe 11 reduce the flame and reduce the amount of combustion.

在此，如第5圖(B)所示，係建構成：當使用前述燃燒器裝置10時，即使減少供應至燃料氣體供應管12之燃料氣體的量及供應至空氣供應管11之空氣的量，如前述那般從主噴射口15a之周圍的各副噴射口15b噴出的燃料氣體也會通過主噴射口15a之周圍的導引部15c而被導引至燃料氣體供應管12的前端外周側，並沿著擴大成錐狀的火焰保持筒14前進，而與通過前述空氣導入孔14a 被導引至火焰保持筒14內的空氣充分地混合並燃燒，使火焰不易消滅，且大幅地確保燃燒器的調節比，而能夠在寬廣的範圍控制燃料氣體的燃燒。 Here, as shown in Fig. 5(B), the system has a configuration: when the aforementioned burner device 10 is used, even if the amount of fuel gas supplied to the fuel gas supply pipe 12 and the amount of air supplied to the air supply pipe 11 are reduced As described above, the fuel gas ejected from the sub-injection ports 15b around the main injection port 15a will also be guided to the outer periphery of the front end of the fuel gas supply pipe 12 through the guide portion 15c around the main injection port 15a. Side, and proceed along the flame holding tube 14 expanded into a cone shape, and fully mix and burn with the air introduced into the flame holding tube 14 through the aforementioned air introduction hole 14a, so that the flame is not easily extinguished, and greatly ensured The turndown ratio of the burner can control the combustion of fuel gas in a wide range.

接著，作為第二加熱處理設備，如第6圖至第8圖所示，就下述情形說明：以貫穿工業用爐20之爐壁21的方式安裝前述燃燒器裝置10的前端部，並且於前述燃燒器裝置10的附近，在燃燒器裝置10的兩側設置收納有蓄熱材31A、31B之一對的蓄熱室30A、30B，且以從各蓄熱室30A、30B貫穿於工業用爐20之爐壁21的方式分別於燃燒器裝置之兩側設置有導引管32A、32B。 Next, as the second heat treatment equipment, as shown in Figs. 6 to 8, the following description will be given: the front end of the aforementioned burner device 10 is installed so as to penetrate the furnace wall 21 of the industrial furnace 20, and In the vicinity of the aforementioned burner device 10, regenerators 30A, 30B containing a pair of heat storage materials 31A, 31B are provided on both sides of the burner device 10, and the regenerators 30A, 30B penetrate through the industrial furnace 20. The furnace wall 21 is provided with guide pipes 32A and 32B on both sides of the burner device.

在此，如第6圖所示，於前述第二加熱處理設備中，在使從前述燃燒器裝置10之燃料氣體供應管12噴出的燃料氣體之量增多的狀態下，進行使藉由收納在前述一方的蓄熱室30A之蓄熱材31A所蓄熱之熱所加熱後的燃燒用空氣通過前述導引管32A朝向從前述燃料氣體供應管12噴出的燃料氣體噴射，而於工業用爐20內使燃料氣體燃燒的動作，另一方面，於另一方的蓄熱室30B，以前述的方式，使燃燒燃料氣體後產生的燃燒排放氣體從工業用爐20內通過前述導引管32B並予以吸收而導引至該蓄熱室30B，而由收納在該蓄熱室30B的蓄熱材31B蓄熱。 Here, as shown in FIG. 6, in the second heat treatment facility, in a state in which the amount of fuel gas ejected from the fuel gas supply pipe 12 of the burner device 10 is increased, it is stored in The combustion air heated by the heat stored in the heat storage material 31A of the regenerator 30A is sprayed toward the fuel gas ejected from the fuel gas supply pipe 12 through the guide pipe 32A, and fuel is used in the industrial furnace 20 The gas combustion operation, on the other hand, in the other regenerator 30B, the combustion exhaust gas generated after burning the fuel gas from the industrial furnace 20 passes through the guide pipe 32B and is absorbed and guided in the aforementioned manner. To the heat storage chamber 30B, the heat storage material 31B stored in the heat storage chamber 30B stores heat.

此外，在此省略了用以將燃料氣體予以噴射或將燃料氣體予以吸取而設置於蓄熱室30A、30B的配管或切換閥的圖式。 In addition, the drawing of the piping or switching valve installed in the regenerator 30A, 30B for injecting fuel gas or sucking the fuel gas is omitted here.

接著，如第7圖所示，在交互地切換一方 的蓄熱室30A與另一方的蓄熱室30B的動作時之切換閥的動作中，係停止從一方的蓄熱室30A使加熱後的燃燒用空氣通過導引管32A朝工業用爐20內噴出的動作，並且於另一方的蓄熱室30B中停止使燃燒燃料氣體後產生的燃燒排放氣體從工業用爐20內通過前述導引管32B而導引至該蓄熱室30B的動作，而以此狀態減少供應至前述燃料氣體供應管12之燃料氣體的量及供應至空氣供應管11之空氣的量。如此一來，即使減少供應至燃料氣體供應管12之燃料氣體的量及供應至空氣供應管11之空氣的量，一旦使用前述的燃燒器裝置10，則如前述那般從主噴射口15a之周圍的各副噴射口15b噴出的燃料氣體也會通過主噴射口15a之周圍的導引部15c而被導引至燃料氣體供應管12之前端外周側，並與通過前述空氣導入孔14a被導引至火焰保持筒14內的空氣充分地混合而燃燒，而防止火焰的消滅。 Next, as shown in Fig. 7, in the operation of the switching valve when the operation of alternately switching between one regenerator 30A and the other regenerator 30B, the heating of the combustion air from one regenerator 30A is stopped. The action of jetting into the industrial furnace 20 through the guide pipe 32A, and stopping the combustion exhaust gas generated after burning the fuel gas in the other regenerator 30B is guided from the industrial furnace 20 through the aforementioned guide pipe 32B To the operation of the regenerator 30B, the amount of fuel gas supplied to the fuel gas supply pipe 12 and the amount of air supplied to the air supply pipe 11 are reduced in this state. In this way, even if the amount of fuel gas supplied to the fuel gas supply pipe 12 and the amount of air supplied to the air supply pipe 11 are reduced, once the aforementioned burner device 10 is used, it will be removed from the main injection port 15a as described above.
