가압송풍용 주철제 섹숀보일러Cast iron section boiler for pressurized air blowing

제1도는 본 고안의 전체 조립 단면도.1 is a cross-sectional view of the entire assembly of the present invention.

제2도는 제1도의 A-A선 단면도.2 is a sectional view taken along the line A-A of FIG.

제3도는 본 고안의 일부 분해사시도.3 is an exploded perspective view of a part of the present invention.

본 고안은 주철제 섹숀보일러를 구성 함에 있어서 각 섹숀사이에 내열성의 세라믹화이바패킹을 대서 섹숀의 연결부가 완전 밀폐상태도 되고 하며 연소실의 후면 섹숀하부에는 압력 조절변의 상부가 유착핀을 기점으로 개폐작용 하도록 탄력설치하여 안전한 운전을 할수 있도록한 가압송풍용 주철제 섹숀보일러에 관한 것이다.The present invention consists of a heat-resistant ceramic fiber packing between each section in the construction of cast iron section boiler, and the connection part of the section is also completely sealed. The present invention relates to a cast iron section boiler for pressurized air blowing which is installed elastically for safe operation.

일반적으로 수관식 보일러에 있어서 연소실의 연소압력을 대기압 이상으로 상승시켜 연료를 연소시킴으로서 증발효율이 향상되어 대기압 이하에서 연소하던 보일러에 비하여 동일한 증기발생량을 기준할 때 보일러의 크기를 작게 할수 있으며 열효율이 향상되는 것은 공지한 바 있다.In general, in a water pipe type boiler, the combustion pressure of the combustion chamber is increased above atmospheric pressure to burn the fuel, so that the evaporation efficiency is improved. It is known to improve.

이를 위하여 강판재로 제작된 수관식 보일러에 있어서는 연소시의 연소압력을 대기압 이상으로 함에는 수관 및 외피등의 강도를 증가시킴으로서 이를 해결하고 있다.To this end, in the case of a water pipe boiler made of steel plate material, this problem is solved by increasing the strength of the water pipe and the shell such that the combustion pressure at the time of combustion exceeds atmospheric pressure.

그러나 기존 대기압이하에서 사용하던 섹숀보일러의 활용을 대기압이상에서 시도하였던 바 각 섹숀의 연결부로 연소가스가 누출되어 연소실의 압력을 대기압 이상으로 하는데는 상당한 문제점이 대두 되었다.However, attempts were made to use the section boilers above atmospheric pressure above atmospheric pressure. Therefore, a significant problem has arisen in that the pressure of the combustion chamber is higher than atmospheric pressure due to the leakage of combustion gas through the connection of each section.

본 고안은 종래 주철제 섹숀보일러의 섹숀을 이용하여 가압송풍에 의한 대기압 이상에서도 연소실내의 기밀성 유지를 간단한 구조로 해결하고 또, 압력조절변의 작동이 원활하게 이루어 지도록한 것인데 이를 첨부도면에 의거 상세히 설명하면 다음과 같다.The present invention solves the airtightness in the combustion chamber with a simple structure by using a section of a conventional cast iron section boiler to maintain the airtightness in the combustion chamber even at atmospheric pressure due to the pressurized air flow, and the pressure regulating valve is made to operate smoothly according to the accompanying drawings. Is as follows.

In the well-known section boiler which is inserted and assembled by the nut 5, heat-resistant ceramic fiber packing S is applied between the junction parts of the section 1, 1 ', 1 ", and each section 1 ( 1 ') (1 ") is attached in a completely sealed state and around the nozzle 22 of the well-known oil burner 21 installed in the front of the boiler main body B, the air supply cylinder 27 and the air supply opening ( 23) to pressurize and blow the combustion air by Fan (28), and the combustion chamber 6 of the boiler body (B) is formed in a circular shape, but connected to the combustion chamber (6) of each section The lower circular water pipe 7 and the upper water pipe 8 are configured to pass through each other so that water is distributed to the entire peripheral surface of the 6 ', and in the middle, on the intermediate water pipe 9 and the intermediate water pipe 9, The horizontal flame passage (10) (10,) is narrowly formed under the middle section Water pipes (8) and (9) assembled at the front and the rear of (1 ') are formed in half to form vertical flame passages (12) and (12') so that the flame in combustion chamber (6 ') is the vertical flame passage (12). 12 'and horizontal flame passages 10 and 10', and the uneven water pipe 13 is vertically communicated inside the rear section 1 ", which is a high heat portion of the combustion chamber 6 '. Therefore, the heat transfer area at the high temperature portion that becomes the end of the flame is widened, and the upper portion of the pressure regulating valve 17 installed in the rear opening 15 of the combustion chamber 6 'has the section 1 " ), And the long holes 17 'and 17 "drilled in the lower portion of the pressure regulating valve 17 are inserted into the fixing bars 18 and 18' and supported by the spring 20, so that the pressure regulating valve 17 is coalesced. The pin 16 was configured to be opened and closed as a starting point.

도면중 미설명부호 21'는 오일버어너(21)의 노즐(22)에 형성된 1차 공기분사구, 24는 급수관, 25는 송출구, 26은 배연통이다.In the drawing, reference numeral 21 ′ denotes a primary air injection port formed at the nozzle 22 of the oil burner 21, 24 is a water supply pipe, 25 is a discharge port, and 26 is a flue gas communication.

이와 같이 구성된 본 고안은 전면 섹숀(1)의 화구(6)에 설치된 통상의 오일버어너(21)의 연료분사노즐(22)에서 연료가 연소실(6')내에서 분무 연소될때, 보일러본체(B)전면의 외부에 설치되어 있는 휀(28)에 의한 강제송풍이 공기공급통(27)의 공기공급구(23)로 2차 연소용 공기가가 압공급케 되므로 이때 연소실(6')에는 대기압 이상의 압력이 유지되어 연소상태가 신속하고 고열 연소케 되며, 이 화염은 후면 섹숀(1")의 내면 요철(凹凸) 수관(13)을 가열함과 동시에 그상부 수직화염통로(12)와 수평화염통로(10')를 통과하여 수직화염통로(12')와 수평화염통로(10)를 거쳐 배열되는 동안 고열부인 연소실(6')의 주위 전면에 형성된 원형수관(7)과 상, 중 수관(8)(9)에 유동되는 물을 효유적으로 가열케되는데, 본 고안은 각 섹숀(1)(1')(1")이 조립되는 그 사이에 내열성의 세라믹화이바패킹(S)이 밀착되어져서 각섹숀(1)(1')(1")의 결합부가 완전한 기밀성이 유지되고 또 연소실(6')을 원통형으로 원형수관(7)으로 둘러 싸이기 때문에 휀(28)에 의하여 공기공급통(27) 및 공기공급구(23)으로 2차 연소공기가 강제로 연수실(6')내에 가압송풍되어도 연소실(6')내의 연소가스가 새지 않어 안전하며 열흡수율이 우수한 효과가 있고 또, 연소실(6')의 내압은 후면섹숀(1")의 개구(15)에 설치된 압력조절변(17)이 일측유착핀(16)을 기점으로 원호작용으로 개폐될때 장공(17')(17")의 범위내에서 고정간(18)(18')에 안내되어 스프링(20)의 탄력을 받으며 자동개폐되므로 압력조절변(17)의 개폐작용이 원할한 효과가 있고 또, 스프링(20)의 탄도 조정은 고정간(18)(18')에 나착시킨 너트(19)를 틀어 조정이 가능하므로 사용이 간편한 것으로 종래의 섹숀보일러의 섹숀을 활용하여 가압 송풍용 보일러로 활용할 수 있으므로 종래것에 비하여 증기발생량을 증대시킬 수 있는 효과가 있다.The present invention configured as described above has a boiler main body when fuel is spray-fired in the combustion chamber 6 'in the fuel injection nozzle 22 of the conventional oil burner 21 installed in the crater 6 of the front section 1. B) Forced air blown by the fan 28, which is installed on the outside of the front surface, causes the secondary combustion air to be supplied to the air supply port 23 of the air supply cylinder 27, so that the combustion chamber 6 ' The pressure above atmospheric pressure is maintained so that the combustion state is rapid and high temperature combustion, and this flame heats the inner uneven water pipe 13 of the rear section (1 ") and at the same time the upper vertical flame passage (12) and the water The circular water pipe 7 formed on the front surface of the combustion chamber 6 ', which is a high heat portion, is arranged while passing through the peace flame passage 10' and through the vertical flame passage 12 'and the horizontal flame passage 10, The water flowing in the heavy water pipes (8) and (9) is heated efficiently, and the present invention is designed to provide heat resistance between each section (1) (1 ') (1 "). Because the mixing bar packing S is in close contact, the joint of each section 1, 1 ', 1 "is maintained in hermetic airtightness, and the combustion chamber 6' is cylindrically surrounded by a circular water pipe 7 Even though the secondary combustion air is forcedly blown into the soft water chamber 6 'by the air cylinder 27 and the air supply port 23 by the fan 28, the combustion gas in the combustion chamber 6' does not leak and is safe and heat. The absorption rate has an excellent effect, and the internal pressure of the combustion chamber 6 'is the pressure control valve 17 installed in the opening 15 of the rear section 1 " The opening and closing action of the pressure regulating valve 17 has a smooth effect because it is guided to the fixed rod 18 and 18 'within the range of the long hole 17' and 17 "and receives the elasticity of the spring 20. In addition, the trajectory adjustment of the spring 20 can be adjusted by turning the nut 19 attached to the fixed rods 18 and 18 '. It can leverage Sean used as the blowing pressure boilers there is an effect that it is possible to increase the steam amount as compared to the prior art.
