본 고안은 1차 공기의 공급속도와 분무컵의 회전속도를 상승시켜 분무되는 연료의 입자를 미세하게 하고 또 분무컵의 중앙에는 경유분사노즐을 설치하여 소량의 경유를 분사시켜 주므로 안정된 화염이 형성되게 하므로 연소가 촉진되도록한 로우터리버어너에 대한 것이다.The present invention increases the supply speed of the primary air and the rotational speed of the spray cup to make fine particles of fuel to be sprayed, and also installs a light oil injection nozzle in the center of the spray cup to inject a small amount of diesel oil to form a stable flame. It is for a rotary burner that allows combustion to be accelerated.
일반적으로 로우터리 버어너는 취급의 간편성 때문에 중질유를 사용하는 보일러에 많이 사용하고 있는데, 이러한 버어너의 연소성능은 분무되는 입자의 크기 등과 밀접한 관계가 있기 때문에 작은 입자를 얻는 것이 매우 중요하며, 이는 1차 공기의 공급속도와 분무컵의 회전속도와 비례 관계에 있었다. 그러나 종래의 로우터리 버어너는 통상 분무컵이 착설된 연소 시스템내에 송풍기를 설치하였기 때문에 송풍기의 직경이 커서 고속회전시 회전 부분의 균형을 유지하는 데 많은 어려움이 있어 주측의 회전속도 증가에 제한을 받게 되므로, 1차 공기의 공급속도와 분무컵의 회전 속도를 필요한 만큼 고속으로 상승시켜 주는데 한계가 있어, 분무되는 연료의 입자를 미세화 할 수 없게 되고 이에 따라 예열 시간이 많이 걸리게 되어 최초 점화 시간이 길어지고 또 연소 상태가 불량하게 되므로 매연이 발생되는 등 공해의 원인이 되며 화염의 중심 부분이 버어너에서 떨어지므로 주화염이 안정되지 못하여 열 손실이 많게 되는 등의 문제점이 있었다.In general, rotary burners are frequently used in heavy oil boilers because of their ease of handling, and since the burner's combustion performance is closely related to the size of the sprayed particles, it is very important to obtain small particles. The rate of supply of primary air was proportional to the rotational speed of the spray cup. However, the conventional rotary burner has a large diameter of the blower because the blower is usually installed in the combustion system in which the spray cup is installed. Therefore, it is difficult to maintain the balance of the rotating part at high speed, thereby limiting the increase in the rotational speed of the main side. As a result, there is a limit to increasing the supply speed of the primary air and the rotational speed of the spray cup as fast as necessary, so that the particles of the fuel to be sprayed cannot be refined, and thus, the preheating time is increased, and thus the initial ignition time is increased. Since the combustion condition is longer and the combustion state is poor, soot is generated, causing pollution, and since the central part of the flame falls from the burner, the main flame is not stabilized and heat loss is increased.
본 고안은 이와 같은 점들을 해결하기 위해 연소시스템 내에서 송풍기를 제거하여 주축의 회전속도를 고속화하며, 증기이젝터를 설치하여 1차 공기의 공급 속도를 상승시켜 주므로 분무되는 입자를 미세하게 하고 회전 확산컵의 중앙에는 경유 분사노즐을 착설하여 소량의 경유를 분사하여 연소시키므로 안정된 화염을 형성할 수 있도록 고안한 것으로 첨부도면에 의거 상술하면 다음과 같다.In order to solve these problems, the present invention removes the blower in the combustion system to speed up the rotational speed of the main shaft, and installs a steam ejector to increase the supply speed of the primary air, thereby minimizing the atomized particles and rotating diffusion. In the center of the cup, a diesel oil injection nozzle is installed to inject a small amount of diesel oil to burn, and thus it is designed to form a stable flame.

On the rear side of the primary air supply pipe 13 connected to the primary air inlet 11, a steam injection nozzle 16, which is closed by the control valve 15, is attached to a steam ejector 14 mounted therein and is blower. It is made by connecting the 17 and the transfer pipe (18).

이와 같이 구성된 본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention configured as described above are as follows.
모우터(21)를 작동시켜 주측(6)을 고속회전시키면 그 외부끝에 끼워 고정된 확산컵(1)과 분무캡(5)이 고속 회전되며, 동시에 송풍기(17)를 작동시키면 공급되는 공기 중의 일부는 이 송관(18)을 통해 증기이젝터(14)내로 이송되고 나머지는 2차 공기 공급관(20)을 따라 이송된다.By operating the motor 21 and rotating the main side 6 at high speed, the diffusion cup 1 and the spray cap 5 fixed to the outer end are rotated at high speed, and at the same time, when the blower 17 is operated, Some are conveyed through the conduit 18 into the steam ejector 14 and the others are conveyed along the secondary air supply conduit 20.
이때, 중질유와 경유를 각기 공급로(24)(25)를 통해 공급시켜 주면 중질유는 공기유입공(2)을 통해 앞쪽 부분이 확산컵(1) 내측에 끼워지는 공급통(24')의 앞쪽 외주면에 뚫어진 각 구멍을 통과하여 분무캡(5) 내로 들어가서 그 측면에 뚫어진 각 연료분출공(3)을 통해 확산컵(1)측으로 분출되며, 경유는 공급관(8)을 통해 분사노즐(9)에서 분사된다.At this time, the heavy oil and light oil are supplied through the supply passages 24 and 25, respectively, and the heavy oil is the front of the supply cylinder 24 'in which the front portion is fitted into the diffusion cup 1 through the air inlet hole 2. Through each hole drilled on the outer circumferential surface, it enters into the spray cap (5) and is ejected to the diffusion cup (1) through each fuel ejection hole (3) drilled on its side, and the diesel oil is injected into the injection nozzle (9) through the supply pipe (8). Sprayed from
이와 같은 상태에서 1차 공기 공급관(13)을 거쳐 공기 유입공(2)으로 들어오는 일부의 공기는 분무캡(5)의 전면에 뚫어 각 공기 분출공(4)을 통해 분출되어 노즐(9)에서 분사되는 경유에 공기를 공급하여 줌과 동시에 이 경유가 필요 이상의 범위로 확산되는 것을 방지하여 주며, 또 중질유는 고속 회전되는 확산컵(1)에 의해 연소실(19)내로 분무 확산되는데 이때, 1차 공기 공급관(13)을 거쳐 분사구(11)로 분사되는 1차 공기가 분무확산되는 중질유에 공급되어 중질유의 분사 속도를 가속시켜 입자가 더욱 미세하게 분산되게 하여 준다.In this state, some of the air that enters the air inlet hole 2 through the primary air supply pipe 13 is drilled through the front of the spray cap 5 and blown out through each air blower hole 4 to discharge from the nozzle 9. It supplies air to the injected diesel oil and prevents the diesel oil from spreading more than necessary range, and heavy oil is spray-spreaded into the combustion chamber 19 by the diffusion cup 1 rotated at a high speed. Primary air injected through the air supply pipe 13 to the injection hole 11 is supplied to the heavy oil to be spray-diffused, thereby accelerating the injection speed of the heavy oil to more finely dispersed particles.
이와 같은 과정에서 노즐(9)을 통해 분사되는 경유에 점화를 하면, 화염이 확산컵(1)에서 분사되는 중질유의 내부에서 버어너 가까이에 형성되므로 분사되는 중질유가 최초의 분사지점에서부터 예열되기 때문에 중질유가 신속하게 착화되며, 또 미세한 입자로 분사되므로 완전연소가 이루어져 주화염이 안정되고 화염직경이 작아지게 되어 열손실도 방지되는 것이다.In this process, when the ignition is performed on the diesel fuel injected through the nozzle 9, since the flame is formed near the burner in the heavy oil injected from the diffusion cup 1, the injected heavy oil is preheated from the first injection point. Heavy oil is ignited quickly and is injected into fine particles, so that complete combustion occurs, so that the main flame is stabilized and the flame diameter is reduced to prevent heat loss.
이와 같은 작동되는 본 고안은 1차 공기 공급관(13)으로 공급되는 1차 공기는 조절변(15)에 의해 조절되는 증기분사노즐(16)에서 분사되는 증기의 압력에 의해 그 공급 속도가 가속화되므로 확산컵(1)에서 확산 분사되는 중질유의 분사속도를 가속시켜 입자의 미세화를 촉진시켜 주게 되며, 또 연소시스템내에서 송풍기가 제거되므로 주측(6)을 고속 회전시켜 줄 수 있고, 이에 따라 분무캡(5)에 부착된 확산컵(1)도 고속회전이 가능하게 되어 중질유의 입자를 더욱 미세하게 분산시켜 주게 됨은 물론, 회전되는 관형상의 주축(6)내에 경유공급관(8)을 고정되게 끼워 그 외부끝에 분사노즐(9)을 착설하였기 때문에 이를 통해 분사되는 소량의 경유가 안정된 화염을 중질유의 내부에서 형성하게 되어 중질유를 버어너 가까이의 최초 분사지점에서 충분히 예열시켜 주므로 신속하고도 효과적으로 연소되게 하여 연소효율이 증대되며, 아울러 연소 상태가 양호하게 되므로 매연 발생이 제거되어 공해방지에도 기여할 수 있게 되는 등 매우 실용적인 고안이다.The present invention operates as described above, since the primary air supplied to the primary air supply pipe 13 is accelerated by the pressure of steam injected from the steam injection nozzle 16 controlled by the control valve 15. Accelerates the injection speed of the heavy oil diffused from the diffusion cup (1) to promote the refinement of the particles, and because the blower is removed in the combustion system, it is possible to rotate the main side (6) at high speed, accordingly the spray cap The diffusion cup (1) attached to (5) can also be rotated at high speed to disperse the fine oil particles more finely, and the diesel oil supply pipe (8) is fixedly inserted into the rotating tubular spindle (6). Since the injection nozzle 9 is installed at its outer end, a small amount of light oil injected through it forms a stable flame inside the heavy oil, so that the heavy oil is sufficiently preheated at the first injection point near the burner. As a result, the combustion efficiency is increased by rapidly and effectively increasing the combustion efficiency, and the combustion state becomes good, so that the generation of soot is eliminated, which contributes to the prevention of pollution.
