Description
本發明係有關於一種具有熱流場均勻化之蓄熱式燃燒器，其係於蓄熱式燃燒器之蓄熱室內部設置一均流構件，藉由均流構件導引一氣體(高溫廢氣) 形成一均勻氣流，並與蓄熱體接觸進行蓄熱作業，以提升蓄熱室內部之熱流場均勻性以及蓄熱量。
The invention relates to a regenerative burner with a uniform heat flow field, which is provided with a current sharing member inside the heat storage chamber of the regenerative burner, and a uniformity member guides a gas (high temperature exhaust gas) to form a uniformity. The airflow is in contact with the heat storage body for heat storage operation to enhance the uniformity of the heat flow field and the heat storage amount inside the heat storage chamber.
蓄熱式燃燒器之燃燒技術，係於作動時將燃燒用之助燃空氣與燃料混合參與燃燒作業，之後將蓄熱式燃燒器作動時排放之高溫廢氣對通過的介質進行蓄熱作業，再把儲熱完成之熱能用以預熱助燃之空氣，以此循環進行熱能回收運用。The combustion technology of the regenerative burner is to mix the combustion air for combustion with the fuel to participate in the combustion operation, and then the high-temperature exhaust gas discharged from the regenerative burner is used for heat storage operation of the passing medium, and then the heat storage is completed. The heat energy is used to preheat the combustion-supporting air, thereby recycling the heat energy.
由於將燃燒技術應用於各領域中，高溫廢氣之排放係為一常態處理作業。因此為了有效回收利用廢氣中的熱能(顯熱)、減少燃料的耗損以及降低高溫廢氣排放造成環境汙染(地球暖化)。方有蓄熱式燃燒技術衍生於各領域進行運用，以因應目前益發受到重視的能源再生利用以及環境保護議題。Since combustion technology is applied to various fields, the discharge of high-temperature exhaust gas is a normal processing operation. Therefore, in order to effectively recycle the heat energy (sensible heat) in the exhaust gas, reduce the fuel consumption, and reduce the high-temperature exhaust gas emissions, environmental pollution (global warming) is caused. The regenerative combustion technology is used in various fields to meet the current issues of energy recycling and environmental protection.
其中上述之介質係為一蓄熱體，根據現今應用於燃燒裝置之熱能回收作業中，陶瓷蓄熱磚或陶瓷蓄熱球係為普遍習知之一蓄熱體。蓄熱體於蓄熱燃燒技術之運用，係用以吸收高溫廢氣中的熱能，並將蓄熱完成之熱能儲存，以供預熱蓄熱式燃燒器作動時所需之助燃空氣。另外陶瓷蓄熱磚相較於陶瓷蓄熱球而言，具有傳熱面積大、壓力損失小、重量輕等優勢。因此在實務運用上，將複數個陶瓷蓄熱磚堆疊於一蓄熱室中，進行蓄熱作業係為較為常見之方式。The above medium is a regenerator, and the ceramic regenerator brick or the ceramic heat storage ball system is a commonly known regenerator according to the heat energy recovery operation applied to the combustion device. The application of the regenerator in the regenerative combustion technology is to absorb the thermal energy in the high-temperature exhaust gas and store the heat stored in the heat storage for the combustion air required for the preheating regenerative burner to operate. In addition, the ceramic heat storage brick has the advantages of large heat transfer area, small pressure loss and light weight compared with the ceramic heat storage ball. Therefore, in practical application, a plurality of ceramic heat storage bricks are stacked in a regenerator, and the heat storage operation is a relatively common method.
依照習知蓄熱室內部之陶瓷蓄熱磚的堆疊方式，係大致為一立方體方式排列呈現。此堆疊方式在進行蓄熱作業時，容易造成先行與廢氣熱能接觸之蓄熱磚能夠獲取較佳之蓄熱量(即位於蓄熱室上方之蓄熱磚)，或者是與氣體流量較為廣泛之區域的蓄熱磚可以獲取較佳之蓄熱量(即相對氣體輸送口，且氣體流量強勁處)。而於蓄熱室下方之蓄熱磚或者是遠離氣體輸送口，且氣體流量薄弱處，因蓄熱磚本身之堆疊方式以及堆疊產生間隙之故，氣體通過該些區域之流域不均以及流速過快，造成蓄熱室內部的熱流場不均勻化現象產生，使得蓄熱室部分區域之蓄熱磚的蓄熱量不佳。According to the stacking manner of the ceramic heat storage bricks in the conventional heat storage chamber, the arrangement is roughly arranged in a cubic manner. In the stacking mode, when the heat storage operation is performed, the heat storage brick which is in contact with the heat energy of the exhaust gas can easily obtain a better heat storage capacity (that is, the heat storage brick located above the heat storage chamber), or the heat storage brick in a region with a relatively wide gas flow can be obtained. The preferred heat storage (ie, relative to the gas delivery port, and the gas flow is strong). However, the heat storage brick below the regenerator is either away from the gas delivery port and the gas flow is weak. Due to the stacking manner of the heat storage brick itself and the gap generated by the stack, the water flow through the regions is uneven and the flow rate is too fast, resulting in The heat flow field unevenness inside the regenerator is generated, so that the heat storage amount of the heat storage brick in the partial area of the regenerator is not good.
另外熱流場不均勻化現象容易致使蓄熱磚部分區域迅速呈現飽和狀態，而無法再行蓄熱。然，因氣體流域不均造成已呈飽和狀態之蓄熱磚持續承受高溫廢氣之熱應力影響，使得此區域之蓄熱磚容易碎裂破損、具有較快之損耗以及較短之壽命。同時亦因此區域之蓄熱磚已然呈現飽和狀態，因此流經該處之高溫廢氣中的熱能並未能持續被蓄熱磚吸收儲熱備用。高溫廢氣並未被完善進行蓄熱作業而排出於大氣中，有造成環境污染(地球溫室效應)以及能源浪費(顯熱無妥善回收利用)之虞。In addition, the phenomenon of uneven heat flow field tends to cause the partial area of the heat storage brick to rapidly become saturated, and it is impossible to store heat again. However, the regenerative bricks that have been saturated due to the uneven gas flow are continuously subjected to the thermal stress of the high-temperature exhaust gas, so that the regenerator bricks in this area are easily broken and damaged, have a relatively fast loss and a short life. At the same time, the regenerative bricks in the area are already saturated, so the heat energy in the high-temperature exhaust gas flowing through the area is not continuously absorbed by the regenerator bricks. High-temperature exhaust gas is not exhausted from the heat storage operation and is discharged into the atmosphere, causing environmental pollution (the global warming effect) and energy waste (the sensible heat is not properly recycled).
於此，為維持蓄熱室內部之熱流場均勻性，以提昇蓄熱室內部之整體蓄熱磚的蓄熱量。遂有改善高溫廢氣流經蓄熱室內部之氣體流量調節以及氣體流域均勻化之必要性。如此一來，蓄熱式內部之蓄熱磚在進行蓄熱作業時，局部蓄熱磚高溫現象以及區域性蓄熱磚的蓄熱量低下之問題方得以獲得改善。Here, in order to maintain the uniformity of the heat flow field inside the heat storage chamber, the heat storage amount of the entire heat storage brick in the heat storage chamber is increased. There is a need to improve the gas flow rate regulation of the high-temperature exhaust gas flowing through the interior of the regenerator and the uniformity of the gas flow area. As a result, the heat storage type internal heat storage bricks are improved in the heat storage operation, the high temperature phenomenon of the local heat storage bricks, and the low heat storage capacity of the regional heat storage bricks.
本發明之主要目的，係提供一種具有熱流場均勻化之蓄熱式燃燒器，其係於一蓄熱室內部設置一均流構件，均流構件位於複數個蓄熱體上方，並相對一輸氣孔。其中均流構件具有複數個孔洞，孔洞之孔徑大小係對應輸氣孔輸送之一氣體流量的強弱分布遞增設置；藉此將均流構件設於輸氣孔以及蓄熱體之間，氣體流經均流構件後，可改善氣體流域不均致使蓄熱室內部之熱流場不均勻化現象。進而提升蓄熱室內部整體之蓄熱體的蓄熱量。The main object of the present invention is to provide a regenerative burner having a uniform heat flow field, wherein a regenerative member is disposed inside a regenerator, and the flow sharing member is located above the plurality of regenerators and opposite to an air vent.

The direction of the exhaust direction is set in the opposite direction. After the gas flows through the holes of the equalizing member, a uniform air flow is formed, so that the heat storage body can be uniformly heated to perform heat storage operation, thereby improving the uniformity of the heat flow field inside the heat storage chamber and the heat storage amount of the entire heat storage body.

為使對本發明之特徵及所達成之功效有更進一步之瞭解與認識，謹佐以較佳之實施例及配合詳細之說明，說明如後：For a better understanding and understanding of the features and advantages of the invention, the preferred embodiments and the detailed description are described as follows:
參閱第一圖以及第二圖，其為本發明一較佳實施例之蓄熱式燃燒器剖面圖以及側向排氣之氣體作動圖A；如圖所示，本發明之蓄熱式燃燒器1包含一燃燒器10，其內部具有至少一蓄熱室102，蓄熱室102內部堆疊複數個蓄熱體1022；一輸氣孔104，係供一氣體1042進出，輸氣孔104之一側連通燃燒器10，另一側連通蓄熱室102。本發明之均流構件106設於蓄熱室102內部，並相對輸氣孔104，且位於蓄熱體1022上方兩者間隔一距離D。均流構件106具有複數個孔洞1062，孔洞1062之孔徑大小係對應氣體1042流量之強弱分布遞增設置；較佳地，蓄熱體1022為蜂巢式陶瓷蓄熱磚，均流構件106為添加10~15%氧化鋯之陶瓷體。Referring to the first and second figures, a cross-sectional view of a regenerative burner and a gas actuation diagram A for lateral exhaust gas according to a preferred embodiment of the present invention; as shown, the regenerative burner 1 of the present invention comprises A burner 10 has at least one regenerator 102 therein, and a plurality of regenerators 1022 are stacked inside the regenerator 102; a gas passage 104 is provided for a gas 1042 to enter and exit, and one side of the gas passage 104 communicates with the burner 10, The other side is connected to the regenerator 102. The current sharing member 106 of the present invention is disposed inside the regenerator 102 and spaced apart from the air vent 104 by a distance D between the regenerators 1022. The flow-receiving member 106 has a plurality of holes 1062. The size of the holes 1062 is correspondingly increased according to the distribution of the flow of the gas 1042. Preferably, the heat storage body 1022 is a honeycomb ceramic heat storage brick, and the flow-flow member 106 is added 10-15%. Ceramic body of zirconia.
按，習知蓄熱式燃燒器1之燃燒器10內部具有至少一蓄熱室102，並將複數個蓄熱體1022堆疊於蓄熱室102內部，蓄熱體1022堆疊完成後大致呈一立方體。當燃燒器10作用產生之一氣體1042(高溫廢氣)經由輸氣孔104導入蓄熱室102時，因輸氣孔104於蓄熱室102中之設置為側向氣體1042輸送(如圖一所示)。此時氣體1042之流動路徑係從左至右不斷地由輸氣孔104輸送至蓄熱室102內部。蓄熱室102內部之區域右方因為接受到較多的氣體1042流量，因此右方區域之蓄熱體1022與氣體1042之接觸時間較長以及流量較大，而可獲取較佳之蓄熱量。The burner 10 of the conventional regenerative burner 1 has at least one regenerator 102 inside, and a plurality of regenerators 1022 are stacked inside the regenerator 102. After the stack of regenerators 1022 is completed, it is substantially a cube. When the burner 10 acts to generate a gas 1042 (high temperature exhaust gas) to be introduced into the regenerator 102 via the air supply hole 104, the air supply hole 104 is disposed in the regenerator 102 and is disposed as the lateral gas 1042 (as shown in FIG. 1). . At this time, the flow path of the gas 1042 is continuously sent from the air vent 104 to the inside of the regenerator 102 from left to right. Since the flow of the gas 1042 is received to the right in the region inside the regenerator 102, the contact time between the regenerator 1022 in the right region and the gas 1042 is long and the flow rate is large, so that a preferable amount of stored heat can be obtained.
另外於蓄熱室102內部之區域左方所能獲取之氣體1042流量，係為氣體1042通過右方區域之蓄熱體1022後所剩餘的流量；以及氣體1042流經右方區域碰到蓄熱室102後，行進方向受到阻擋而變更流動方向往左方區域移動。因此越靠近輸氣孔104位置之氣體1042越薄弱，此區域之蓄熱體1022所能獲取之氣體1042流量較為稀少，使得位於蓄熱室102區域左方之蓄熱體1022的蓄熱量低下。Further, the flow rate of the gas 1042 which can be obtained to the left of the region inside the regenerator 102 is the flow rate remaining after the gas 1042 passes through the regenerator 1022 in the right region; and the gas 1042 flows through the right region and hits the regenerator 102. The traveling direction is blocked and the flow direction is changed to move to the left area. Therefore, the weaker the gas 1042 located closer to the position of the gas vent 104, the smaller the flow rate of the gas 1042 that can be obtained by the heat storage body 1022 in this region is, so that the heat storage amount of the heat storage body 1022 located to the left of the heat storage chamber 102 region is lowered.
爾後氣體1042往下一層之蓄熱體1022進行蓄熱作業時，因氣體1042本身之流動路徑以及流量所致，區域右方之氣體1042流量仍然大於區域左方。使得右方區域之蓄熱體1022仍能獲取較佳之蓄熱量，左方區域之蓄熱體1022的蓄熱量仍然低下，造成蓄熱室102內部整體之熱流場均勻性不佳。When the gas 1042 is subjected to the heat storage operation of the heat storage body 1022 of the next layer, the flow rate of the gas 1042 on the right side of the area is still larger than the left side of the area due to the flow path and the flow rate of the gas 1042 itself. The heat storage body 1022 in the right region can still obtain a better heat storage amount, and the heat storage amount of the heat storage body 1022 in the left region is still low, resulting in poor uniformity of the heat flow field inside the heat storage chamber 102.
其中熱流場均勻性不佳將導致局部蓄熱體1022高溫現象產生，即位於右方區域之蓄熱體1022因熱應力之故而較快耗損，容易造成此區域之蓄熱體1022碎裂、破損；而位於左方區域之蓄熱體1022因未能獲取或獲取較少之氣體1042接觸時間以及流量較小，有蓄熱量低下之問題產生。The poor uniformity of the heat flow field will result in the high temperature phenomenon of the local heat storage body 1022, that is, the heat storage body 1022 located in the right region is quickly depleted due to thermal stress, and the regenerator 1022 in this region is easily broken and damaged; The regenerator 1022 in the left region has a problem of low heat storage due to failure to acquire or acquire a small amount of gas 1042 contact time and a small flow rate.
蓄熱室102內部之熱流場均勻性不佳，係因氣體1042流經各部位之蓄熱體1022的流量不均所致，進而衍生局部蓄熱體1022高溫現象(蓄熱室102區域右方)、局部蓄熱體1022蓄熱量低下(蓄熱室102區域左方)以及無法提升蓄熱室102內部整體之蓄熱體1022的蓄熱量等問題。The uniformity of the heat flow field inside the regenerator 102 is not good due to the uneven flow rate of the regenerator 1022 flowing through the respective portions of the gas 1042, and further the high temperature phenomenon of the local regenerator 1022 (the right side of the regenerator 102 region) and the local heat storage. The body 1022 has a low heat storage amount (to the left of the regenerator 102 region) and a problem that the heat storage amount of the heat storage body 1022 in the entire regenerator 102 cannot be increased.
復參閱第一圖，並一併參閱第三圖，其為本發明一較佳實施例之側向排氣之氣體作動圖B；如圖所示，為了改善蓄熱室102內部之熱流場均勻性以及提升整體蓄熱體1022之蓄熱量。本發明係將均流構件106設置於蓄熱室102內部，並相對輸氣孔104，且位於蓄熱體1022上方。其中均流構件106所具有之複數個孔洞1062的孔徑大小係對應輸氣孔104排氣方向之相反方向遞增設置。即靠近蓄熱室102右方區域之孔洞1062的孔徑較小，而靠近輸氣孔104方向之孔洞1062的孔徑較大。Referring to the first figure, and referring to the third figure, which is a gas actuating diagram B of the lateral exhaust gas according to a preferred embodiment of the present invention; as shown, in order to improve the uniformity of the heat flow field inside the regenerator 102 And increasing the heat storage amount of the entire heat storage body 1022. In the present invention, the current sharing member 106 is disposed inside the regenerator 102, and is located above the heat storage hole 104 and above the heat storage body 1022. The aperture size of the plurality of holes 1062 of the current sharing member 106 is incrementally set corresponding to the opposite direction of the exhaust direction of the air inlet 104. That is, the aperture 1062 near the right region of the regenerator 102 has a smaller aperture, and the aperture 1062 near the direction of the vent 104 has a larger aperture.
如此一來，當輸氣孔104輸送氣體1042進入蓄熱室102後，因位於區域右方之均流構件106的孔洞1062可供氣體1042通過之範圍縮減，致使氣體1042通過均流構件106之右方區域的孔洞1062飽和後，必須往左方區域移動，使左方區域之孔洞1062亦能獲取較多之氣體1042流量。In this way, when the gas delivery hole 104 conveys the gas 1042 into the regenerator 102, the hole 1062 of the flow equalizing member 106 located on the right side of the region can be reduced in the range through which the gas 1042 can pass, so that the gas 1042 passes through the right side of the flow sharing member 106. After the hole 1062 of the square area is saturated, it must be moved to the left area, so that the hole 1062 in the left area can also obtain more gas 1042 flow.
均流構件106依據氣體1042之流動路徑以及流量強弱分布，而對應設置孔洞1062之孔徑，使得氣體1042流經均流構件106後，於各區域之流量皆為相同，形成一均勻氣流1044。如此當氣流1044流經下一層之蓄熱體1022進行蓄熱作業時，各區域之蓄熱體1022仍能均勻接觸氣流1044中的熱能，而有效提升蓄熱量。The flow equalizing member 106 is correspondingly disposed according to the flow path of the gas 1042 and the flow intensity distribution, and correspondingly sets the aperture of the hole 1062, so that the gas 1042 flows through the flow equalizing member 106, and the flow rates in the respective regions are the same, forming a uniform air flow 1044. Thus, when the airflow 1044 flows through the heat storage body 1022 of the next layer for heat storage operation, the heat storage bodies 1022 of the respective regions can uniformly contact the heat energy in the airflow 1044 to effectively increase the heat storage amount.
於此，位於蓄熱室102內部之蓄熱體1022，因透過均流構件106調節氣體1042流量，致使蓄熱室102內部各區域之蓄熱體1022皆能獲取相同之氣體1042接觸時間以及氣體1042流量。改善局部蓄熱體1022高溫現象，提升蓄熱室102內部區域右方之蓄熱體1022的壽命，以及提升蓄熱室102內部區域左方之蓄熱體1022的蓄熱量，解決局部蓄熱體1022之蓄熱量低下問題。進而使蓄熱室102內部之熱流場均勻化，以提升蓄熱室102內部之整體蓄熱體1022的蓄熱量。Here, the heat storage body 1022 located inside the regenerator 102 adjusts the flow rate of the gas 1042 through the flow equalizing member 106, so that the regenerator 1022 in each region inside the regenerator 102 can acquire the same gas 1042 contact time and the gas 1042 flow rate. The high temperature phenomenon of the local heat storage body 1022 is improved, the life of the heat storage body 1022 on the right side of the inner portion of the heat storage chamber 102 is increased, and the heat storage amount of the heat storage body 1022 on the left side of the inner portion of the heat storage chamber 102 is raised, thereby solving the problem of low heat storage capacity of the local heat storage body 1022. . Further, the heat flow field inside the regenerator 102 is made uniform to increase the amount of heat stored in the entire heat storage body 1022 inside the regenerator 102.
參閱第四圖、第五圖以及第六圖，其為本發明另一較佳實施例之蓄熱式燃燒器剖面圖、直下式排氣之氣體作動圖A以及直下式排氣之氣體作動圖B；如圖所示，本發明之另一實施例係當輸氣孔104設置於均流構件106上方時(如第四圖所示)，均流構件106之孔洞1062孔徑的對應設置。Referring to FIG. 4, FIG. 5 and FIG. 6 , FIG. 4 is a cross-sectional view of a regenerative burner according to another preferred embodiment of the present invention, a gas actuation diagram A of a direct exhaust gas, and a gas actuation diagram B of a direct exhaust gas. As shown, another embodiment of the present invention is a corresponding arrangement of apertures 1062 of the flow equalization member 106 when the air vent 104 is disposed above the averaging member 106 (as shown in the fourth figure).
當蓄熱式燃燒器1未設置均流構件106時(如第五圖所示)，輸氣孔104輸送燃燒器10作動時產生之氣體1042(高溫廢氣)，係直接由上而下地往蓄熱室102內部之中央區域流動。此時位於中央區域之蓄熱體1022能夠獲取較多的氣體1042流量，而有較佳之蓄熱量。然，位於蓄熱室102兩側區域之氣體1042流量，係為氣體1042通過中央區域之蓄熱體1022後所剩餘的流量。因此遠離輸氣孔104位置之氣體1042較為薄弱，即兩側區域之蓄熱體1022所能獲取之氣體1042流量較為稀少，使得位於蓄熱室102兩側區域之蓄熱體1022的蓄熱量不佳。When the regenerative burner 1 is not provided with the flow equalizing member 106 (as shown in the fifth figure), the gas delivery hole 104 conveys the gas 1042 (high temperature exhaust gas) generated when the burner 10 is actuated, directly from the top to the bottom to the regenerator The central area of 102 flows. At this time, the heat storage body 1022 located in the central area can acquire a larger flow rate of the gas 1042, and has a better heat storage amount. However, the flow rate of the gas 1042 located in the region on both sides of the regenerator 102 is the flow rate remaining after the gas 1042 passes through the regenerator 1022 in the central region. Therefore, the gas 1042 which is far from the position of the gas vent 104 is relatively weak, that is, the flow rate of the gas 1042 which can be obtained by the heat storage body 1022 in the both sides is relatively small, so that the heat storage amount of the heat storage body 1022 located in the both sides of the heat storage chamber 102 is not good.
爾後氣體1042往下一層之蓄熱體1022進行蓄熱作業時，因氣體1042本身之流動路徑以及流量所致，中央區域之氣體1042流量仍然大於兩側區域。使得中央區域之蓄熱體1022仍能獲取較佳之蓄熱量，兩側區域之蓄熱體1022的蓄熱量仍然低下，造成蓄熱室102內部整體之熱流場均勻性不佳。When the gas 1042 is subjected to the heat storage operation of the heat storage body 1022 of the next layer, the flow rate of the gas 1042 in the central region is still larger than that on both sides due to the flow path and the flow rate of the gas 1042 itself. The heat storage body 1022 in the central region can still obtain better heat storage, and the heat storage amount of the heat storage body 1022 in the both sides is still low, resulting in poor uniformity of the heat flow field inside the heat storage chamber 102.
其中熱流場均勻性不佳將導致局部蓄熱體1022高溫現象產生，即位於中央區域之蓄熱體1022因熱應力之故而較快耗損，容易造成此區域之蓄熱體1022碎裂、破損；而位於兩側區域之蓄熱體1022因未能獲取或獲取較少之氣體1042接觸時間以及流量較小，有蓄熱量不佳之問題產生。The poor uniformity of the heat flow field will result in the high temperature phenomenon of the local heat accumulator 1022, that is, the heat storage body 1022 located in the central region is quickly depleted due to thermal stress, and the regenerator 1022 in this region is easily broken and damaged; The regenerator 1022 in the side region has a problem of poor heat storage due to failure to acquire or acquire a small amount of gas 1042 contact time and a small flow rate.
蓄熱室102內部之熱流場均勻性不佳，係因氣體1042流經各部位之蓄熱體1022的流量不均所致，進而衍生出局部蓄熱體1022高溫現象(蓄熱室102中央區域)、局部蓄熱體1022蓄熱量低下(蓄熱室102兩側區域)以及無法提升蓄熱室102內部整體之蓄熱體1022的蓄熱量等問題。The uniformity of the heat flow field inside the regenerator 102 is poor due to the uneven flow rate of the regenerator 1022 flowing through the respective portions of the gas 1042, thereby deriving the high temperature phenomenon of the local regenerator 1022 (the central region of the regenerator 102) and local heat storage. The body 1022 has a low heat storage amount (a region on both sides of the regenerator 102) and a problem that the heat storage amount of the heat storage body 1022 in the entire regenerator 102 cannot be increased.
復參閱第四圖以及第六圖，為了改善蓄熱室102內部之熱流場均勻性以及提升蓄熱室102內部整體之蓄熱體1022的蓄熱量。本發明係將均流構件106設置於蓄熱室102內部，並相對輸氣孔104，且位於蓄熱體1022上方兩者間隔一距離D。其中均流構件106所具有之孔洞1062孔徑大小係對應輸氣孔104之排氣方向而往兩側遞增設置。即靠近蓄熱室102中央區域之孔洞1062的孔徑較小，而遠離輸氣孔104之兩側方向的孔洞1062孔徑較大。Referring to the fourth and sixth figures, in order to improve the uniformity of the heat flow field inside the regenerator 102 and to increase the amount of heat stored in the heat storage body 1022 inside the regenerator 102. In the present invention, the current sharing member 106 is disposed inside the regenerator 102, and is spaced apart from the air inlet 104 by a distance D between the regenerators 1022. The aperture 1062 of the current sharing member 106 has a hole size corresponding to the exhaust direction of the air inlet 104 and is incrementally disposed on both sides. That is, the hole 1062 near the central portion of the regenerator 102 has a smaller aperture, and the hole 1062 away from the both sides of the vent 104 has a larger aperture.
如此一來，當輸氣孔104輸送氣體1042進入蓄熱室102後，因位於中央區域之均流構件106的孔洞1062可供氣體1042通過之範圍縮減，致使氣體1042通過均流構件106之孔洞1062飽和後，必須往兩側區域移動，使得兩側區域之孔洞1062亦能獲取較多之氣體1042流量。As a result, when the gas delivery hole 104 conveys the gas 1042 into the regenerator 102, the hole 1062 of the flow equalizing member 106 located in the central region can be reduced in the range through which the gas 1042 can pass, so that the gas 1042 passes through the hole 1062 of the flow equalizing member 106. After saturation, it must move to both sides, so that the holes 1062 on both sides can also obtain more gas 1042 flow.
均流構件106依據氣體1042之流動路徑以及流量強弱分布，而對應設置孔洞1062之孔徑，使得氣體1042流經均流構件106後，於各區域之流量皆為相同，形成一均勻氣流1044。如此當氣流1044流經下一層之蓄熱體1022進行蓄熱作業時，各區域之蓄熱體1022仍能均勻接觸氣流1044中的熱能，而有效提升蓄熱量。The flow equalizing member 106 is correspondingly disposed according to the flow path of the gas 1042 and the flow intensity distribution, and correspondingly sets the aperture of the hole 1062, so that the gas 1042 flows through the flow equalizing member 106, and the flow rates in the respective regions are the same, forming a uniform air flow 1044. Thus, when the airflow 1044 flows through the heat storage body 1022 of the next layer for heat storage operation, the heat storage bodies 1022 of the respective regions can uniformly contact the heat energy in the airflow 1044 to effectively increase the heat storage amount.
於此，位於蓄熱室102內部之蓄熱體1022，因透過均流構件106調節氣體1042流量，致使蓄熱室102內部各區域之蓄熱體1022皆能獲取相同之氣體1042接觸時間以及氣體1042流量。改善局部蓄熱體1022高溫現象，提升蓄熱室102內部中央區域之蓄熱體1022的壽命，以及提升蓄熱室102內部兩側區域之蓄熱體1022的蓄熱量，解決局部蓄熱體1022之蓄熱量低下問題。進而使蓄熱室102內部之熱流場均勻化，以提升蓄熱室102內部之整體蓄熱體1022的蓄熱量。Here, the heat storage body 1022 located inside the regenerator 102 adjusts the flow rate of the gas 1042 through the flow equalizing member 106, so that the regenerator 1022 in each region inside the regenerator 102 can acquire the same gas 1042 contact time and the gas 1042 flow rate. The high temperature phenomenon of the local heat storage body 1022 is improved, the life of the heat storage body 1022 in the central region of the heat storage chamber 102 is increased, and the heat storage amount of the heat storage body 1022 in the both sides of the heat storage chamber 102 is increased, thereby solving the problem of low heat storage amount of the local heat storage body 1022. Further, the heat flow field inside the regenerator 102 is made uniform to increase the amount of heat stored in the entire heat storage body 1022 inside the regenerator 102.
由上述具體實施例可得知本發明所揭示之具有熱流場均勻化之蓄熱式燃燒器，係將均流構件對應輸氣孔設置於蓄熱室內部。根據輸氣孔輸送之氣體流動路徑以及氣體流量強弱分布遞增設置孔洞大小，使氣體流量均勻分布於蓄熱室內部各區域。蓄熱室內部之熱流場均勻化後，可以有效提升整體蓄熱體之蓄熱量，同時減少局部蓄熱體因高溫現象(熱應力)所造成的損耗，以及改善局部蓄熱體無法有效進行蓄熱作業，而有蓄熱量不佳之問題。According to the above specific embodiment, the regenerative burner having the uniform heat flow field disclosed in the present invention is characterized in that the flow-receiving member is disposed in the heat storage chamber corresponding to the gas transmission hole. According to the gas flow path of the gas transmission hole and the gas flow intensity distribution, the hole size is set incrementally, so that the gas flow rate is evenly distributed in each area of the heat storage chamber. After the heat flow field inside the regenerator is homogenized, the heat storage of the entire regenerator can be effectively increased, and the loss of the local regenerator due to high temperature (thermal stress) can be reduced, and the local regenerator can not be effectively stored for heat storage. The problem of poor heat storage.
