그리고, 상기 폐열회수장치(300)를 사용하지 않을 시에는 순환라인(330)의 밸브(350)(360)를 차단함과 동시에 제1난방수 순환라인(150)의 제어밸브(151)를 개방하여 제1난방수 순환라인(150)을 통하는 난방수의 열을 전달받아 순환라인(330)을 순환하는 난방수를 가열한다.When the waste heat recovery apparatus 300 is not used, the valves 350 and 360 of the circulation line 330 are blocked and at the same time, the control valve 151 of the first heating water circulation line 150 is opened. By receiving the heat of the heating water passing through the first heating water circulation line 150 to heat the heating water circulating through the circulation line 330.
한편, 도 3과 같이 보일러(210)로부터 가열된 난방수는 난방수 순환라인 (260)을 따라 연속적으로 순환하면서 각 가정의 난방을 수행하게 되는데. 이때 배기덕트(230)를 통해 배출되는 배기가스 및 연소 중에 발생한 고열량인 잠열은 댐퍼(231)의 유도를 받아 화살표와 같이 유입덕트(310)로 안내되고, 유입덕트(310)로 유입된 배기가스는 폐열회수장치(300)를 통과하게 되며, 상기 폐열회수장치 (300)를 거친 배기가스는 배출덕트(320)를 통해 배기덕트(230)로 배출된다.Meanwhile, as shown in FIG. 3, the heating water heated from the boiler 210 circulates continuously along the heating water circulation line 260 to perform heating of each home. At this time, the exhaust gas discharged through the exhaust duct 230 and latent heat generated during combustion are guided to the inlet duct 310 as shown by the arrow 231 under the guidance of the damper 231, and the exhaust gas introduced into the inlet duct 310. Is passed through the waste heat recovery device 300, the exhaust gas passing through the waste heat recovery device 300 is discharged to the exhaust duct 230 through the exhaust duct 320.
상기 폐열회수장치(300)로 유입된 고온(150℃∼200℃)의 폐열에 의해 열흡수관(302)내의 난방수가 가열되며, 이렇게 가열된 난방수는 순환라인(330)을 따라 연속적으로 순환하여 각 가정의 난방을 수행하게 된다.The heating water in the heat absorption pipe 302 is heated by waste heat of high temperature (150 ° C. to 200 ° C.) introduced into the waste heat recovery device 300, and the heated water is continuously circulated along the circulation line 330. Each home is heated.
그리고, 상기 폐열회수장치(300)를 사용하지 않을 시에는 순환라인(330)의 밸브(350)(360)를 차단함과 동시에 난방수 순환라인(260)의 제어밸브(261)를 개방하여 난방수를 순환라인(330)에 공급하여 소망하는 난방을 수행한다.In addition, when the waste heat recovery device 300 is not used, the valves 350 and 360 of the circulation line 330 are blocked, and the control valve 261 of the heating water circulation line 260 is opened to heat the heating. The water is supplied to the circulation line 330 to perform the desired heating.
따라서, 본 발명은 배기덕트의 적소에 고온으로 배출되는 배기가스 및 연소중에 발생한 고열량인 잠열에 의해 난방수가 가열되도록 폐열회수장치를 설치한 다음, 상기 폐열회수장치에 의해 가열된 난방수를 지정된 가정으로 연속적으로 순환하여 소망하는 난방을 수행하므로서 에너지효율을 극대화시키는 동시에 연료소모를 절약하여 사용자의 비용부담을 극소화시킨 유용한 효과가 있다.Therefore, the present invention is to install the waste heat recovery device so that the heating water is heated by the exhaust gas discharged at a high temperature in the exhaust duct and the latent heat of high heat generated during combustion, and then the heating water heated by the waste heat recovery device is designated. By continually circulating to perform the desired heating, it has the useful effect of maximizing energy efficiency and saving fuel consumption and minimizing user's cost burden.
