본 발명은 스터링 엔진 배열회수 장치에 관한 것으로서,더욱 상세하게는 휜 튜브형 증발관 내부에서 발생된 증기가 증기관을 통하여 스터링 엔진의 히터부를 가열하도록 한 스터링 엔진 배열회수 장치에 관한 것이다.The present invention relates to a Stirling engine heat recovery device, and more particularly, to a Stirling engine heat recovery device for allowing steam generated inside the fin tube type evaporation tube to heat the heater of the Stirling engine through the steam pipe.
일반적으로, 스터링 엔진은 외연기관의 일종이다. 고온의 열이 엔진의 팽창기에 가해지면 내부의 작동 유체가 팽창하여 축 동력을 발생시킨다. 팽창된 작동 유체는 재생기를 통과하여 냉각기에 도달하게 된다. 이곳에서 외부 냉각수로의 냉각 작용에 의하여 수축된 후 다시 재생기를 통과하여 팽창부로 보내어진다. 이러한 사이클 작용에 의하여 열에너지를 축 동력으로 전환 시키게 된다. In general, a stirling engine is a type of external combustion engine. When hot heat is applied to the inflator of the engine, the working fluid inside expands to generate axial power. The expanded working fluid passes through the regenerator and reaches the cooler. It is contracted by the cooling action to the external cooling water, and then passes through the regenerator to the expansion unit. This cycle action converts thermal energy into axial power.
상기 작동원리에서와 같이 스터링 엔진은 기존의 내연 기관과는 달리 모든 종류의 가연성 물질을 열원으로 할 수 있는 것이 가장 큰 장점이다. 연소로에서 일차로 제품을 가열한 후 배출되는 배기 가스를 스터링 엔진의 열원으로 사용할 수 있다. 연소로의 배기가스를 스터링 엔진의 열원으로 하여 축동력을 발생시킬 경우 대기중으로 방출되는 배기가스의 열에너지를 회수하여 재이용할 수 있어 에너지 절감과 환경오염 저감에 기여하게 된다.As in the above operating principle, the stirling engine has the greatest advantage that, unlike the conventional internal combustion engine, all kinds of combustible materials can be used as heat sources. Exhaust gases emitted after the product is first heated in the furnace can be used as a heat source for a stirling engine. When axial power is generated using the exhaust gas of the combustion furnace as the heat source of the stirling engine, the thermal energy of the exhaust gas released into the atmosphere can be recovered and reused, contributing to energy saving and environmental pollution reduction.
그러나, 연소로의 배기가스 덕트를 통하여 배출되는 배기가스는 그 온도가 200~400℃ 범위에 들기 때문에 고온의 연소가스에 비하여 에너지 밀도가 낮아 부피가 크다. 이 때문에 이를 직접적으로 스터링 엔진의 팽창기에 적용하기 위해서는 팽창기의 용적이 증대되어야 한다. However, since the exhaust gas discharged through the exhaust gas duct of the combustion furnace is in the temperature range of 200 ~ 400 ℃ low energy density compared to the high-temperature combustion gas is bulky. For this reason, the volume of the expander must be increased in order to apply it directly to the expander of the stirling engine.
팽창기의 용적이 증대될 경우 스터링 엔진의 내부 작동 유체의 양이 증대되어 팽창기에서 재생기, 재생기에서 냉각기 간의 이동성이 저하될 뿐만 아니라 작동 유체와 배기가스 간에 열 전달이 충분히 이루어 지지 않는 문제가 발생 된다. Increasing the volume of the expander increases the amount of internal working fluid of the Stirling engine, which not only reduces mobility between the regenerator in the inflator and the cooler in the regenerator, but also causes insufficient heat transfer between the working fluid and the exhaust gas.
이러한 현상은 스터링 엔진을 이용한 배기가스 보유열의 재이용에 있어서 주요한 문제로 지적되어 왔다.This phenomenon has been pointed out as a major problem in the reuse of exhaust gas holding heat using a stirling engine.
이를 해결하기 위한 방안으로써 배기가스로부터 증기를 생산하여 에너지 밀도를 증대시킨 후에 스터링 엔진의 팽창기에 적용하는 방안이 제시되고 있다.As a solution to this problem, a method of producing steam from exhaust gas to increase energy density and then applying it to an inflator of a stirling engine has been proposed.
그러나 이러한 방법에 있어서도 증기를 발생시키기 위한 보일러, 팽창기를 통과하고 난 증기를 액화시키기 위한 응축기 그리고 응축된 액체를 다시 보일러로 공급하기 위한 급액 펌프 등과 같은 부가적인 장치가 필요하다.However, this method also requires additional equipment such as a boiler for generating steam, a condenser for liquefying the steam passing through the expander, and a liquid feed pump for feeding the condensed liquid back to the boiler.
이러한 부가장치는 설치 공간 및 제어가 필요하고, 추가적인 비용증가의 원인이 되는 문제점이 있었다.These additional devices require installation space and control, and there was a problem that causes additional cost increase.
본 발명은 상술한 문제점을 해결하기 위한 것으로서, 휜 튜브형 증발관 내부에서 발생된 증기가 증기관을 통하여 스터링 엔진의 히터부를 가열하도록 한 스터링 엔진 배열회수 장치를 제공한다.The present invention has been made to solve the above-described problems, and provides a Stirling engine heat recovery apparatus for allowing steam generated inside the tubular evaporator tube to heat the heater of the Stirling engine through the steam tube.
상기와 같은 목적을 달성하기 위한 본 발명의 스터링 엔진 배열회수 장치는, 상기 스터링 엔진에 설치된 팽창기에서 응축된 증기가 유입되는 응축액 관과, 상기 응축액 관과 연결되는 배기가스 덕트와, 상기 배기가스 덕트 내에 설치되는 휜 튜브형 증발관과, 상기 휜 튜브형 증발관에서 발생 된 증기를 팽창기로 보내기 위해 연결된 증기관이 형성되는 것을 포함한다.Sterling engine heat recovery apparatus of the present invention for achieving the above object, the condensate pipe to which the steam condensed in the expander installed in the stirling engine flows, the exhaust gas duct connected to the condensate pipe, and the exhaust gas duct And a steam tubular evaporator tube installed therein, and a steam tube connected to send steam generated from the steam tubular evaporator tube to the expander.
바람직하게는, 상기 휜 튜브형 증발관에 물 또는 열매체를 충전하여, 배기가스 열에 의하여 증기가 발생토록 하는 것을 더 포함할 수 있다.Preferably, the fin tube type evaporation tube may further include filling water or a heat medium so that steam is generated by exhaust gas heat.
