본 고안은 송풍기로부터 공급되는 공기가 고체 연료인 분탄공급관으로 역풍되는 것을 방지하기 위하여 송풍기 상부에 별개의 작은 송풍구를 형성하여 분탄공급통 내에 연관된 분탄공급관에 연관시키고 연소실내에 연관된 분탄공급관의 상부에 수개의 작은 통공을 뚫어 주므로서 역풍되는 공기와 송풍기로부터 공급되는 공기가 연소실내로 배기되게 한 역풍방지장치에 관한 것으로 종래의 분탄 온수보일러는 송풍기로부터 공급되는 공기가 일부는 분탄공급관을 통하여 분탄 공급통내의 분탄에 함유된 분진을 외부로 비산시켜 비위생적인 문제점이 있었다.The present invention is to form a separate small blower in the upper part of the blower in order to prevent the air supplied from the blower back to the coal supply pipe is a solid fuel, and associated with the coal supply pipe associated in the coal supply tank and to the upper part of the coal supply pipe associated in the combustion chamber The present invention relates to an anti-wind device that allows back air and air supplied from a blower to be exhausted into a combustion chamber by drilling several small holes. In the conventional coal-fired hot water boiler, some of the air supplied from the blower is supplied through a coal supply pipe. There was an unsanitary problem by scattering the dust contained in the coal in the barrel to the outside.

본 고안은 이와같은 문제점을 적게하기 위하여 분탄공급관에 송풍기로부터 적은량의 공기를 공급시켜 분탄공급관으로 역풍되는 것을 방지케한 것으로 첨부도면에 의하여 상세히 설명하면 다음과 같다.The present invention is to prevent the backwind to the coal supply pipe by supplying a small amount of air from the blower to the coal supply pipe in order to reduce such problems as described in detail by the accompanying drawings as follows.

보일러 동체(1)의 내부에 다수의 통기공(2)을 뚫으 테이퍼진 연소통(3)을 장설하고 그 주위에 공기공급실(4)을 형성하여 송풍기(5)와 연관시키고 보일러동체(1)와 송풍기(5) 사이에 입자상의 분탄공급통(6)을 장설하고 그 하내부에서 수평으로 연소통(3)의 하부에 연관시킨 입자상의 분탄 이송관(7)내에 이송스크류(8)을 장설한 공지한 것에 있어서 송풍기(5)의 상부에 보조송풍구(9)를 형성하여 연료공급통(6)에 연관된 입자상의 분탄이송관(7)에 송풍유도관(10)으로 연관시키고 연소실내에 위치한 입자상의 분탄이송관(7)의 상부에 수개의 공기분출장공(11)을 뚫어서 된 것이다.In the boiler body 1, a plurality of vent holes 2 are drilled, and a tapered combustion cylinder 3 is installed, and an air supply chamber 4 is formed around the boiler body 1 so as to be associated with the blower 5 and the boiler body 1 Particulate coal supply cylinder 6 is installed between the air blower 5 and the blower 5, and a transfer screw 8 is installed in the granular coal transfer pipe 7 connected to the lower part of the combustion cylinder 3 horizontally from the bottom thereof. In one known embodiment, an auxiliary tuyer 9 is formed on the upper part of the blower 5 so as to be connected to the particulate coal transfer pipe 7 associated with the fuel supply container 6 with a blow induction pipe 10 and located in the combustion chamber. It is made by drilling several air ejection holes 11 in the upper part of the granular coal transport pipe 7.

이상과같이 된 본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention made as described above are as follows.

보일러동체(1)의 내부에 다수의 통기공(2)을 뚫은 테이퍼진 연소통(3)을 장설하고 그 주위에 공기공급실(4)을 형성하여 송풍기와 연관시키고 보일러동체(1)와 송풍기(5) 사이에 입자상의 분탄공급통(6)을 장설하고 그 하내부에서 수평으로 연소통(3)의 하부에 연관시킨 입자상의 분탄이송관(7) 내에 이송스크류(8)을 장설하고 송풍기(5)의 상부에 보조송풍구(9)를 형성하여 연료공급통(6)에 연관된 입자상의 분탄이송관(7)에 송풍유도관(10)으로 연관시키고 연소실내에 위치한 입자상의 분탄이송관(7)의 상부에 수개의 공기분출장공(11)을 뚫었기 때문에 입자상의 분탄이송관(7) 내에 장설된 이송스크류(8)에 의하여 연소통(3)으로 공급되는 입자상의 분탄을 연소시키는데 필요한 공기를 송풍기(5)에서 발생시킨 공기를 공기공급실(4)에 보내어 연소통(3)의 주위에 다수뚫은 통기공(2)을 통하여 공급시켜 연소시키게 되는데 이때 공급되는 공기가 입자상의 분탄이송관(7) 내로 역류하는 공기는 송풍기(5)의 상부에 형성한 보조송풍구(9)로 통풍되는 적은 양의 공기가 송풍유도관(10)을 통하여 입자상의 분탄이송관(7)에 공급되는 공기에 의하여 입자상의 분탄공급통(6)으로 역류되지 않고 연소실에 위치한 입자상의 분탄이송관(7)의 상부에 뚫은 공기분출 장공(11)을 통하여 연소실내로 분출되므로 역류하는 공기에 의하여 비산되는 분진이 거의없어 보일러실이 항상 청결한 이점이 있는 것이다.In the inside of the boiler body 1, a tapered combustion cylinder 3 having a plurality of vent holes 2 is installed, and an air supply chamber 4 is formed around the boiler body 1 to associate with the blower, and the boiler body 1 and the blower ( 5) Install the granular coal supply cylinder 6 in between, install the transfer screw 8 in the granular coal transfer pipe 7 which is connected to the lower part of the combustion cylinder 3 horizontally in the lower part thereof, and blower ( 5, an auxiliary tuyeres 9 are formed on the upper part thereof, and are connected to the particulate coal transfer pipe 7 associated with the fuel supply container 6 with the blowing induction pipe 10, and the particulate coal transfer pipe 7 located in the combustion chamber. Since several air ejection holes 11 are drilled on the upper part of the air), the air necessary for burning the particulate powdered coal supplied to the combustion cylinder 3 by the conveying screw 8 installed in the particulate coal conveying pipe 7 is provided. Air from the blower (5) is sent to the air supply chamber (4), It is supplied through the vent hole (2) to combust the air flowing back into the particulate coal transport pipe (7) is a small amount of air to be vented to the secondary air outlet (9) formed on the upper of the blower (5) Of the particulate coal transfer pipe 7 located in the combustion chamber without being flowed back into the particulate coal supply cylinder 6 by the air supplied to the particulate coal transfer pipe 7 through the blowing induction pipe 10. Since the air is ejected into the combustion chamber through the air ejection hole 11, there is almost no dust scattered by the air flowing back has the advantage that the boiler room is always clean.
