화목보일러의 버너부 구조{Burner Structure of Firewood Boiler}Burner Structure of Firewood Boiler {Burner Structure of Firewood Boiler}

본 발명은 화목을 투입하여 보일러 연료로 사용하는 화목보일러에 관한 것으로, 특히 화목이 연소하는 버너부에 보다 충분한 공기를 공급하여 완전연소를 유도하면서 화목 연소시 편축으로 타는 것을 방지한 화목보일러의 버너부 구조에 관한 것이다.The present invention relates to a firewood boiler used as a boiler fuel by injecting a firewood, and more particularly, to supply a sufficient amount of air to a burner in which a firewood burns to induce complete combustion while preventing burnt in a single shaft during burning a firewood. It is about the substructure.

공지된 바와 같이 화목보일러는 그 연료로 나무와 같은 목재를 이용하여 열교환기에서 온수난방을 수행할 수 있도록 되어 있는 보일러로서, 일반적인 구조는 내화재로 감싸진 본체 내부에 화목연료를 저장하는 화목저장공간부와, 이 화목저장공간부의 하방쪽으로 설치된 버너부, 이 버너부에 연하여 설치되는 열교환기 등을 갖추고 있다.As is known, a coal fired boiler is a boiler that can perform hot water heating in a heat exchanger using wood such as wood as its fuel, and a general structure is a firewood storage space for storing a coal fuel inside a body wrapped with a fireproof material. Section, a burner section provided below the firewood storage space section, a heat exchanger installed in connection with the burner section, and the like.

한편 본 출원인에 의해 기히 출원된 화목보일러는 도 4에 도시된 바와 같이 본체로 둘러 쌓인 화목적재공간부(105)와, 내화재로 이루어진 버너부(102)가 설치되는 가로지지대(103), 이 버너부(102)의 화염이 분사되는 연소실(104) 및, 상기 버너부(102)와 화목적재공간부(101)로 외부공기를 공급하는 1차 공기송풍기(106),2차공기송풍기(101)로 이루어진 화목보일러에 있어서, 상기 본체는 수실(111)로 이루어진 열교환기로 형성되어 있으며, 상기 가로지지대(103)는 양선단에서 테이퍼면을 이루고 이 테이퍼면을 접하면서 하향 공기유도홈들이 버너부(102) 쪽으로 평행되게 이격 형성되고, 이 가로지지대(103)의 중앙부에 설치된 버너부(102)는 상부버너와 하부버너의 이중버너로 형성되며, 상기 연소실(104)과 연통된 배기부가 구비되고, 이 배기부의 상부에 다수개의 배출파이프(114)가 설치되며서 이 배출파이프 (114)를 감싸는 열교환기(113)가 설치된 구조로 되어 있었다.On the other hand, the firewood boiler is already filed by the present applicant is a horizontal support 103, the burner unit 102 made of a firewood material space space 105 and the burner unit 102 is surrounded by a body as shown in Figure 4, the burner Combustion chamber 104 to which the flame of the part 102 is injected, and a primary air blower 106 and a secondary air blower 101 for supplying external air to the burner part 102 and the firewood loading space 101. In the hwamok boiler consisting of, the main body is formed of a heat exchanger consisting of a water chamber 111, the horizontal support 103 forms a tapered surface at both ends and the downward air induction grooves are in contact with the tapered surface burner ( It is formed parallel to the 102 spaced apart, the burner portion 102 is installed in the center of the horizontal support 103 is formed of a double burner of the upper burner and the lower burner, the exhaust portion communicating with the combustion chamber 104, Multiple discharges on top of this exhaust Tape 114 is installed, and a standing surrounding the exhaust pipe 114, there is a structure in the heat exchanger 113 is installed.

이와 같은 종래 화목보일러에서 버너부(102)에 공급되는 공기는 1차공기송풍기(106)를 통하여 연소용 공기로 사용되고, 단지 2차공기송풍기(101)를 매개로 1쌍의 공기 노즐(115)만을 통하여 공급되기 때문에 여러가지 장점이 있었으나, 화목연소시 완전 연소를 유도하기에는 문제점이 있었다.The air supplied to the burner unit 102 in the conventional coal fired boiler is used as combustion air through the primary air blower 106, and only a pair of air nozzles 115 through the secondary air blower 101. Since it is supplied through the bay, there were various advantages, but there was a problem in inducing complete combustion when burning firewood.

즉 화목적재공간부(105)에 적재된 화목에는 1차공기송풍기(106)를 통하여 유입되는 공기(도 4의 화살표 참조)의 유로가 많이 유입되는 부분에서 화목이 편축으로 연소되기 때문에 불안전 연소가 발생할 수 있으며, 화목연소시 완전연소를 위해 화목의 하부쪽인 버너부에서 연소되어져야 하나, 주연소용 공기가 상부에서 공급됨으로서 공기의 흐름에 따라 화목의 상부로 화염이 전달되거나 한쪽으로 치우쳐 편축으로 연소되어 지는 단점이 있다.That is, unstable combustion occurs because the firewood is burned uniaxially in the section where the flow path of air (see arrow in FIG. 4) flowing through the primary air blower 106 flows into the firewood loaded in the firewood loading space 105. It may occur, and when burning the firewood, it should be burned in the burner part at the lower side of the firewood for complete combustion, but the main combustion air is supplied from the upper side, so the flame is transferred to the upper part of the firewood according to the air flow or is biased to one side. There is a disadvantage of being burned.

더욱이 화목연소시 버너부의 급격한 온도상승으로 이 금속성의 버너부가 자주 훼손 되거나 뒤틀어지기 때문에 빈번하게 수리 또는 교체해야 하는 문제점도 있었다.In addition, there is a problem in that the burner part is frequently damaged or distorted due to the rapid temperature rise of the burner unit when burning firewood, so that the repair or replacement is frequently required.

이에 본 발명은 상기와 같은 종래 문제점을 해결하기 위해 발명된 것으로, 버너부에서 화목연소시 버너부에 2,3차공기를 공급하여 보다 완전연소를 유도하여 연소효율의 증대를 꾀할 수 있으면서 적재된 화목이 버너쪽인 하부로부터 차례대로 연소하여 편축연소를 방지하고, 버너의 급격한 온도상승을 예방하여 버너수명이 연장되는 화목보일러의 버너부 구조를 제공함에 그 목적이 있다.Therefore, the present invention was invented to solve the conventional problems as described above, and when the burner part is burned while being fired, the second and third air is supplied to the burner part to induce more complete combustion to increase the combustion efficiency. It is an object of the present invention to provide a burner structure of a firewood boiler in which burner life is burned sequentially from a lower part of the burner side to prevent uniaxial combustion and to prevent a sudden rise in temperature of the burner.
