In general, a steam boiler burns fuel and transmits its heat of combustion to water to generate high temperature steam. The steam generated is used for industrial or agricultural purposes, and for general heating and hot water.

하지만, 연소실과 연소열로 가열되는 증기실로 구성되는 기존의 증기보일러는, 연소실 용량 및 연료비와 대비하여 연소효율은 떨어지는 단점이 있어 널리 보급되지 못하는 것이었다.However, the conventional steam boiler composed of a combustion chamber and a steam chamber heated by the heat of combustion has a disadvantage in that the combustion efficiency is inferior to the combustion chamber capacity and the fuel cost, and thus cannot be widely used.

일 예로, 많은 양의 열에너지를 필요로 하는 대중 목욕탕의 경우에는 하나의 증기보일러로는 난방, 온수 및 급탕, 사우나에 필요한 증기를 모두 생산할 수가 없 어 난방 및 온수용 보일러와 사우나용 보일러를 각각 별도로 설치 사용해야 하므로 그 설비비 등 경제적 부담감이 상당히 큰 실정이었다.For example, in a public bath that requires a large amount of thermal energy, one steam boiler cannot produce all the steam required for heating, hot water and hot water, and a sauna. Since the installation must be used, the economic burden such as the equipment cost was very large.

또한, 본 발명은, 한대의 보일러를 사용함에도 다목적, 다용도, 대용량의 보일러 역할을 충분하게 소화해내며 오히려 그 유지비는 감소되는 목재 연료 증기보일러를 제공함에 그 목적이 있다. It is also an object of the present invention to provide a wood-fueled steam boiler capable of sufficiently extinguishing the role of a multi-purpose, versatile and large-capacity boiler even when using a single boiler, but reducing its maintenance cost.

따라서, 본 발명은, 폐열 회수를 위한 연관(416)이 설치되는 연소실(402)과 연소실(402)의 연소열로 가열되어 고온 고압의 증기를 생산 배출하는 증기실(404)로 구성되는 본체부(4)와, 연관(416)으로 회수된 폐열이 폐열관(612)을 통해 이송되어 연소가스 배출관(810)으로 나가는 도중에 증기실(404)에 공급되는 물과 연소 실(402)에 공급되는 공기를 각각 데우도록 하는 급수예열부(6) 및 공기예열부(8)로 구성되도록 함을 특징으로 한다.Accordingly, the present invention, the main body portion consisting of a combustion chamber 402, which is provided with an association 416 for waste heat recovery, and a steam chamber 404 that is heated by the heat of combustion of the combustion chamber 402 to produce and discharge high-temperature, high-pressure steam ( 4) and the water supplied to the combustion chamber 402 and the water supplied to the steam chamber 404 while the waste heat recovered by the associated pipe 416 is transferred through the waste heat pipe 612 to the combustion gas discharge pipe 810.

In addition, the waste heat of the remaining combustion chamber 402 after supplying as much combustion heat as necessary to the steam chamber 404 allows radially mounting and recovering dozens of associations 416 on the inner wall of the combustion chamber 402, And it is configured to continuously transfer to the waste heat pipes (612, 612a, 612b) through the waste heat chamber (416a) lower steam chamber (404).

도 5는 본 발명의 급수예열부의 단면 구성도이고, 도 6은 본 발명의 공기예열부의 단면 구성도이며, 도 7은 본 발명의 공기분사구의 평단면도이다.5 is a cross-sectional configuration diagram of the water supply preheating unit of the present invention, FIG. 6 is a cross-sectional configuration diagram of the air preheating unit of the present invention, and FIG. 7 is a plan cross-sectional view of the air injection port of the present invention.

본체부(4)의 증기실(404)에 공급되는 물(W2)은 급수예열부(6)에서 폐열에 의해 미온으로 데워진 물이며, 급수예열부(6)는 본체부(4)와 별도로 장치되고 증기실(404)로 연결 구성된다. 즉, 급수예열부(6)는 도 5에서처럼, 폐열관(612a)의 일부를 둘러싸고 형성되는 급수예열관(604)과, 급수예열관(604)으로 외부의 물(W1)이 급수펌프(614)에 의해 공급되는 1차급수관(602)과, 급수예열관(604) 내의 데워진 물(W2)을 증기실(404)로 보내어 주는 2차급수관(410)을 연결 구성한다. The water W2 supplied to the steam chamber 404 of the main body 4 is water warmed lukewarm by waste heat in the water supply preheating unit 6, and the water supply preheating unit 6 is a device separate from the main body 4. And connected to the steam chamber 404. That is, the water supply preheating unit 6 is a water supply preheating tube 604 formed around a part of the waste heat pipe 612a, and the water W1 external to the water supply preheating tube 604 as shown in FIG.

지금부터 본 발명의 구성을 토대로 목재 연료 증기보일러(2)의 작동을 설명하기로 한다.The operation of the wood fuel steam boiler 2 will now be described based on the configuration of the present invention.

본체부(4)의 연료투입구(424)를 통하여 연소실(402)로 목재 연료를 투입하고 이를 발화하면, 연소실(402) 내에 발생되는 연소열이 증기실(404)의 물을 가열하여 고온 고압의 증기(S)를 발생하고, 이 증기는 본체부(4)의 외부로 노출 구성되는 증기배출구(406)를 통하여 배출한다.When the wood fuel is injected into the combustion chamber 402 through the fuel inlet 424 of the main body 4 and fired, the combustion heat generated in the combustion chamber 402 heats the water in the steam chamber 404 to provide high temperature and high pressure steam. (S) is generated, and this steam is discharged through the steam discharge port 406 configured to be exposed to the outside of the main body 4.

그리고, 온수탱크(442)의 물은 증기실(404)의 열교환기(440) 내를 회전하면서 뜨거워져서 급수관(446)을 통해 급탕용으로 공급된다. Then, the water of the hot water tank 442 is heated while rotating in the heat exchanger 440 of the steam chamber 404 is supplied for the hot water supply through the water supply pipe 446.

한편, 상기 연소실(402) 내의 폐열은 모터(M)의 동력으로 작동하는 송풍팬(610)에 의하여 수십 개의 연관(416)을 통해 회수되고 폐열실(416a)을 거쳐 폐열관(612)(612a)(612b)으로 연속 이송된다.Meanwhile, the waste heat in the combustion chamber 402 is recovered through the dozens of pipes 416 by the blower fan 610 operated by the power of the motor M, and the waste heat pipes 612 and 612a through the waste heat chamber 416a. To 612b.

When lukewarm water W2 is supplied to the steam chamber 404 through the secondary water supply pipe 410, the water supply control gauge 412 measures the amount of water in the steam chamber 404 so that the water is automatically supplied as it decreases. If necessary, the valve 814 of the externally exposed secondary water supply pipe 410 is manually adjusted.

또, 급수예열부(6)를 통과한 폐열은, 공기예열부(8)에서 링브로워(806)의 작동으로 외기투입관(808)을 통해 들어온 차가운 공기가 미지근하게 데워진 공기(HA)로 공기공급관(812)을 따라 본체부(4) 내 연소실(402)에 공기분사구(418)로 회오리치듯 분사되어 목재 연소 시에 화력을 최대화하는데 필요한 연소 기체를 공급하게 된다.In addition, the waste heat that has passed through the water supply preheating unit 6 is air to the air (HA) in which cold air, which has been lukewarmly warmed up through the air inlet pipe 808 by the operation of the ring blower 806 in the air preheating unit 8, is warmed. The gas is injected into the combustion chamber 402 in the main body 4 along the supply pipe 812 to the air injection port 418 to supply the combustion gas required to maximize the thermal power during the wood burning.

마지막으로, 상기 공기예열부(8)까지 들어온 폐열은 외기를 데움과 동시에 무거운 잔사는 하부 잔사분리구(814)에 낙하되어 분리 배출 가능하게 되고, 남은 연소가스는 상부 연소가스 배출관(810)을 통하여 외부로 배출된다. Finally, the waste heat introduced up to the air preheating unit 8 warms the outside air and at the same time the heavy residue falls to the lower residue separator 814 to be separated and discharged, and the remaining combustion gas is the upper combustion gas discharge pipe 810. Through the outside.

미설명부호 ‘408’은 증기안전변, ‘420’은 압력계, ‘422’는 압력차단기, ‘430’은 연소재 배출구이다.408 is the steam safety valve, 420 is the pressure gauge, 422 is the pressure breaker and 430 is the combustor outlet.

지금까지 설명한 바와 같이 본 발명은, 연료비가 매우 저렴하고 폐열을 재이용하여 연소효율을 높아 경제적이며, 구조가 간단하여 제조하기가 쉬고, 연소 후의 잔재와 가스가 분리 배출되므로 환경오염의 우려가 없는 등의 효과가 있다.As described so far, the present invention is very economical because the fuel cost is very low, the waste heat is reused, the combustion efficiency is high, the structure is simple, the production is easy, and the residues and gases after combustion are separated and discharged, so there is no fear of environmental pollution. Has the effect of.
