Description

Tubular Boiler

종래의 관류보일러는 도 4에서와 같이 하부급수드럼에서 곧바로 증발수관으로 급수가 이루어지게한 구성이기 때문에 급수되는 물은 증발수관내에서 일정수위를 유지하고 있는 적은 관수량만 가열이 이루어지므로 순간 증발량이 적고 급수된 물을 가열하는데 많은 시간이 걸리게 되어 증발효율이 떨어지고 연료소모가 많아지며 버너의 화염이 일정수위를 유지하게 되는 증발수관내의 수면상측부에 직접 접촉되어 가열되므로 증발수관의 수명이 크게 단축되었었다.Since the conventional perfusion boiler is configured to supply water to the evaporation water pipe immediately from the lower water supply drum as shown in FIG. 4, the water supplied is instantaneously evaporated because only a small amount of water is maintained in the evaporation water pipe. It takes a lot of time to heat the water supply, so that the evaporation efficiency decreases, fuel consumption increases, and the burner's flame is heated in direct contact with the upper surface of the evaporated water pipe, which maintains a constant water level. It was greatly shortened.

본 고안은 이러한 문제점을 해결하기 위하여 상·하부드럼이 증발수관으로 연통되는 관류보일러 관체의 하부급수드럼을 격벽으로 분할구획시켜 급수실과 가열수실로 구성한다음 급수관과 증발수관을 상부증기드럼에 연통되게 설치하되 급수관 상측의 상부증기드럼에 범람실을 구성하여 급수관을 통해 범람실 내에 유입된 물이 오버플로워(Over Flower)되어 증발수관의 수위를 유지할수 있도록한 것이다.In order to solve these problems, the present invention divides the lower water supply drum of the perfusion boiler tube into which the upper and lower drums communicate with the evaporating water pipe into partition walls, and constitutes the water supply chamber and the heating water chamber, and the water supply pipe and the evaporation water pipe are connected to the upper steam drum. It is installed, but the flooding chamber is formed in the upper steam drum above the water supply pipe so that the water introduced into the flooding room through the water supply pipe overflows (over flower) to maintain the level of the evaporation water pipe.

이하 본 고안을 더욱 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in more detail.

상부증기드럼(10)과 하부급수드럼(20)이 노통부(40)에 설치된 증발수관(31)으로 연통되어 버너(41)의 화염에 의해 가열된 과열증기를 증기출구(13)로 배출시키는 관류보일러에 있어서, 하부급수드럼(20)을 격벽(21)으로 분할구획시켜 내·외측에 급수실(22)과 가열수실(23)을 각각 구성한다음 급수관(30)과 증발수관(31)을 상부증기드럼(10)에 연통되게 설치하되 급수관(30) 상측의 상부증기드럼(10)에 범람실(11)을 구성하여 범람실(11)에서 오버플로워(Over Flower)되어 급수되는 방법으로 증발수관(31)의 수위(W)를 유지시키도록 한다.The upper steam drum 10 and the lower water supply drum 20 communicate with the evaporated water pipe 31 installed in the furnace part 40 to discharge the superheated steam heated by the flame of the burner 41 to the steam outlet 13. In the perfusion boiler, the lower water supply drum 20 is divided into partitions 21 to form the water supply chamber 22 and the heated water chamber 23 inside and outside, respectively, and then the water supply pipe 30 and the evaporation water pipe 31 are separated. It is installed in communication with the upper steam drum 10 but the overflow steam 11 is formed in the upper steam drum 10 above the water supply pipe 30 to overflow from the flood chamber 11 (Over Flower) to be evaporated by water supply. It is to maintain the water level (W) of the water pipe (31).

그리고, 2열로 배치된 증발수관(31) 상측의 상부증기드럼(10)에 차단벽(12)을 형성하여 범람실(11)에서 오버플로워되는 물이 내측의 증발수관(31)에만 급수가 되도록한 것이다.Then, the barrier wall 12 is formed in the upper steam drum 10 on the upper side of the evaporated water pipe 31 arranged in two rows so that the water overflowed from the flooding chamber 11 is supplied only to the inner evaporated water pipe 31. It is.

이와같이된 본 고안은 관류보일러의 증발수관(31)에 급수된 물이 가열되어 발생된 과열증기가 상부증기드럼(10)을 통해 증기출구(13)로 배출이 이루어지는 것은 통상의 방법과 같이 이루어진다.In the present invention, the superheated steam generated by heating the water supplied to the evaporating water pipe 31 of the perfusion boiler is discharged to the steam outlet 13 through the upper steam drum 10 as in the conventional method.

이때, 본 고안의 증발수관(31)에 급수되는 물은 도 1에서와 같이 하부급수드럼(20)에 분할구획시킨 내측의 급수실(22)에서 급수관(30)을 통해 상승하여 상부증기드럼(10)에 구성한 범람실(11) 내에 유입된 다음 오버플로워(Over Flower)되어 증발수관(31)의 수위를 유지시키게 되는 것이다.At this time, the water supplied to the evaporation water pipe 31 of the present invention rises through the water supply pipe 30 in the inner water supply chamber 22 partitioned into the lower water supply drum 20 as shown in FIG. It is introduced into the flooding chamber 11 configured in 10) and then overflowed (Over Flower) to maintain the level of the evaporated water pipe (31).

즉, 범람실(11) 내의 물은 증발수관(31)에 물이 급수되기 전에도 노통부(40)에 설치된 급수관(30)이 버너(41)의 화염으로 가열되면서 급수관(30) 내의 물을 소정온도이상으로 유지시키게 되므로 그만큼 관수량이 많아져서 순간증발량을 증대시킬수 있게되고, 이렇게 어느정도 가열된 물이 증발수관(31)에 급수되어 수위를 유지하므로 증발수관(31) 내의 증기발생효율을 대폭 향상시킬수 있게 될뿐만 아니라 이에 따른 연료절감효과를 얻을수 있게 된다.That is, the water in the floodplain 11 is pre-determined water in the water supply pipe 30 while the water supply pipe 30 installed in the furnace part 40 is heated by the flame of the burner 41 even before the water is supplied to the evaporated water pipe 31. Since it maintains above the temperature, the amount of water is increased so that the instantaneous evaporation amount can be increased, and thus the water heated to some extent is supplied to the evaporation water pipe 31 to maintain the water level, thereby greatly improving the steam generation efficiency in the evaporation water pipe 31. Not only can this be done, but it also saves fuel.

또, 버너(41)의 화염이 내측의 만수된 급수관(30)에는 직접 접촉되고 일정수위를 유지하게 되는 증발수관(31)에는 화염의 직접적인 영향을 받지않게 되므로 증발수관(31)의 수위상면이 쉽게 손상되는 것을 방지할수 있게되어 보일러수명을 크게 늘릴수 있게 되는 것이다.In addition, since the flame of the burner 41 is not directly affected by the flame in the evaporated water pipe 31 which is in direct contact with the inner full water supply pipe 30 and maintains a constant water level, the water level upper surface of the evaporated water pipe 31 is It is possible to prevent the damage easily and to greatly increase the life of the boiler.

한편, 본 고안의 급수관(30)을 통해 유입된 물이 범람실(11)에서 오버플로워되면서 2열로 배치된 증발수관(31)에 한꺼번에 급수가 이루어지도록 할수도 있고, 차단벽으로 내측의 증발수관(31)에만 급수되고 외측의 증발수관(31)에는 직접적인 급수가 되지않고 하부 가열수실(23)을 통해 급수가 이루어져서 증발수관(31)의 수위를 유지시킬수 있게 되는 것으로 이는 버너의 형태나 증기발생효율에 따라 선택적으로 사용할수 있는 것이다.On the other hand, the water introduced through the water supply pipe 30 of the present invention overflows from the flooding chamber 11, so that the water supply to the evaporated water pipes 31 arranged in two rows can be made at once, the inner wall of the evaporated water pipe as a blocking wall The water is supplied to only the 31 and the water is supplied through the lower heating water chamber 23 without directly supplying water to the evaporated water pipe 31 on the outside, so that the water level of the evaporated water pipe 31 can be maintained. It can be used selectively according to the efficiency.

이와같이 본 고안은 증발수관에 급수되는 물이 승강오버헤드방식으로 이루어지므로 순간 증발량을 증대시킬수 있고 증기발생효율 및 연료절감효과가 대폭 향상되고 연료절감효과가 있는 관류보일러를 얻을수 있는 이점이 있는 것이다.As such, the present invention has the advantage of increasing the instantaneous amount of evaporation since the water supplied to the evaporating water pipe is elevated by the elevating overhead method, and greatly improving the steam generation efficiency and the fuel saving effect and obtaining the perfusion boiler having the fuel saving effect.
