본 고안은 가열로등의 공업로에서 화염온도를 측정하는 열전대(Thermocouple)에 관한 것으로 특히 금속보호관, 비금속보호관, 석영관을 차례로 구분관착하고, 이 보호관의 중공(中空) 중심선상에 +, -소선을 일체로 매입한 절연체를 관설하여서되는 화염 온도측정용 열전대에 관한 것이다.The present invention relates to a thermocouple measuring flame temperature in an industrial furnace such as a heating furnace. In particular, a metal protective tube, a non-metal protective tube, and a quartz tube are sequentially separated and installed on the hollow center line of the protective tube. It relates to a thermocouple for flame temperature measurement by providing an insulator in which element wires are integrally embedded.
제품의 가열, 소성, 균열, 시간조정등 적절한 가열패턴(Pattern) 설정으로 연소관리의 합리화, 연료원 단위감소, 적정버어너(Burner)선택 및 제품의 품질향상을 도모하기 위하여 정확한 화염온도를 측정하여야 하나 화염이 수평상태로 길기 때문에 열전대에 휨발생과 측정소요시간이 장시간 걸리기 때문에, 측정의 효과를 거둘 수 없다.Accurate flame temperature measurement for rationalization of combustion management, reduction of fuel unit, selection of proper burner and improvement of product quality by proper heating pattern setting such as heating, firing, cracking, and time adjustment of products. However, since the flame is long in the horizontal state, the thermocouple may be warped and take a long time, so the effect of the measurement cannot be achieved.
즉, 수평으로 설치하는 열전대, 특히 길이가 긴 열전대에 있어서는 휨 발생이 문제가되며, 화염온도를 조업에 이용하기 위해서는 온도 감지시간이 단시간이어야 한다. 본 고안에서는 이러한 문제점을 해결하기 위하여, 보호관을 위치별로 다른 재질로 사용하므로 종래의 문제점을 해결한 것으로 첨부도면에 의해 설명하면 다음과 같다.That is, in the case of horizontally installed thermocouples, especially long thermocouples, warpage is a problem, and in order to use the flame temperature for operation, the temperature sensing time must be short. In order to solve this problem, the present invention solves the conventional problem because the protective tube is used as a different material for each position.
백금(Plantium: Pt)선으로 된 -소선(1)과 백금로듐(Pt-Rh)선으로 된 +소선(2)을 관(管)상으로 된 절연체(Insulator)(3)에 삽입한 후 끝단을 용접한다. 열전대 프레임(Frame)(8)에 스테인레스(Stainless)강으로 된 금속보호관(5)을 나착하였으며, 금속보호관(5) 끝단에 알루미나(Alumina)로 된 비금속보호관(6)을 끼우되 금속보호관(5)과 사이에는 글라스올(Glass Wool)(4)로 충진하였다. 끝단에는 석영(Quartz)관(7)으로 하되 비금속보호관(6)과는 글라스울(4)로 충진하였다.Insert the -small wire (1) made of platinum (Pt) wire and the + small wire (2) made of platinum rhodium (Pt-Rh) wire into the tubular insulator (3). Weld A metal protective tube (5) made of stainless steel was attached to the thermocouple frame (8), and a non-metal protective tube (6) made of alumina (Alumina) was inserted at the end of the metal protective tube (5). ) And was filled with glass wool (4). The end was made of quartz tube (7), but the non-metallic protective tube (6) and the glass wool (4) was filled.
이와 같이 구성된 본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention configured as described above are as follows.
가열로, 균열로 등의 공업로에 있어서 화염은 보통수평 상태로 형성되므로 열전대의 설치도 수평상태로 유지되어야 한다. 이때 열전대의 지지는, 열전대 프레임(8)과 금속보호관(5)에 의해 지지된다.In industrial furnaces, such as heating furnaces and cracking furnaces, flames are usually formed in a horizontal state, so the installation of thermocouples should be maintained in a horizontal state. At this time, the support of the thermocouple is supported by the thermocouple frame 8 and the metal protective tube 5.
종래의 보호관은 일체로 되어 있기 때문에 끝단부에서는 보호관 자중과 고열에 의해 휨이 발생되나 본 고안의 열전대는 비금속보호관(6)과 석영관(7)은 가벼우므로 휨발생이 완전 방지되며 화염온도를 측정하는 끝단부가 석영관(7)으로 되어있기 때문에 온도감지 속도가 종래에 비해 단축되었으며, 절연체(3)는 +, -소선 (1)(2)을 보호하여 열화를 방지한다. 이때 열전대 프레임(8)과 금속보호관(5) 및 비금속보호관(6)등은 계속해서 사용이 되며, 석영관(7)만 1회용이므로 교체하여 사용한다. 이와같이 보호관 자중에 의한 휨발생 방지와 온도측정시간이 단축되어 종래의 문제점을 완전 해결한 고안이다.Since the conventional protection tube is integrated, bending occurs at the end due to the protection tube weight and high temperature. However, the thermocouple of the present invention is light in non-metal protection tube (6) and quartz tube (7), so that warpage is completely prevented. Since the end to be measured is made of a quartz tube (7), the temperature sensing speed is shorter than in the prior art, and the insulator (3) protects the + and-wires (1) (2) to prevent deterioration. At this time, the thermocouple frame 8, the metal protective tube (5) and the non-metal protective tube (6) continue to be used, and the quartz tube (7) is used only once, so replace it. In this way, the prevention of bending caused by the weight of the protective tube and the temperature measurement time are shortened, and the present invention is completely solved.
