도 1은 본 발명에 따른 폐열 회수율이 극대화된 소각 보일러를 나타낸 정면도, 도 2는 본 발명에 따른 폐열 회수율이 극대화된 소각 보일러를 나타낸 측면도이다.FIG. 1 is a front view showing an incineration boiler with a maximized waste heat recovery rate according to the present invention, and FIG. 2 is a side view showing an incineration boiler with a maximized waste heat recovery rate according to the present invention.

도 1 내지 도 2에 도시된 바와 같이, 본 발명에 따른 폐열 회수율이 극대화된 소각 보일러(100)은 유체하우징(10), 1차연소챔버(20), 2차연소챔버(30), 송풍기(40), 열교환챔버(50), 연결관(60), 배기하우징(70)을 포함한다.1 and 2, an incineration boiler 100 having a maximized waste heat recovery rate according to the present invention includes a fluid housing 10, a primary combustion chamber 20, a secondary combustion chamber 30, a blower 40, A heat exchange chamber 50, a connection pipe 60, and an exhaust housing 70.

상기 유체하우징(10)은 유체가 저장되는 저장탱크이다. 이 때, 유체는 물이 이용될 수 있다.The fluid housing 10 is a storage tank in which fluid is stored. At this time, the fluid may be water.

상기 1차연소챔버(20)는 상기 유체하우징(10)에 설치되며, 연료 연소에 의해 열과 배기가스가 발생하여 상기 유체하우징(10)에 채워진 유체를 가열한다. 이 때, 상기 1차연소챔버(20)의 연료 연소에 의해 가열된 고온 유체는 고온 유체가 필요한 곳으로 공급된다.The primary combustion chamber 20 is installed in the fluid housing 10 and generates heat and exhaust gas by fuel combustion to heat the fluid filled in the fluid housing 10. [ At this time, the high temperature fluid heated by the fuel combustion of the primary combustion chamber 20 is supplied to the place where the high temperature fluid is required.

또한, 상기 1차연소챔버(20)는 일면에 연료가 투입될 수 있는 개폐도어가 설치되며, 연료는 저가인 폐기물, 괴탄, 코크스 또는 목재를 사용할 수 있다.In addition, the primary combustion chamber 20 may be provided with an opening / closing door through which fuel can be injected on one side, and low-cost wastes, algae, coke, or wood can be used.

상기 2차연소챔버(30)는 상기 1차연소챔버(20)에서 이송된 배기가스가 유입되어 배기가스의 재연소가 이루어지게 된다.The exhaust gas transferred from the primary combustion chamber 20 flows into the secondary combustion chamber 30, and the exhaust gas is re-burned.

상기 송풍기(40)는 상기 2차연소챔버(30)에 유입된 배기가스가 연소되도록 상기 2차연소챔버(30)로 산소(혹은 대기중 공기)를 공급한다. 이에 따라, 상기 2차연소챔버(30)에 배기가스의 재연소가 이루어질 수 있는 환경이 조성되어 배기가스의 재연소가 이루어지게 된다.The blower 40 supplies oxygen (or atmospheric air) to the secondary combustion chamber 30 so that the exhaust gas flowing into the secondary combustion chamber 30 is burned. Accordingly, an environment in which the secondary combustion chamber 30 is capable of re-burning the exhaust gas is provided, and the exhaust gas is re-burned.

상기 열교환챔버(50)는 상기 2차연소챔버(30)에서 이송된 배기가스가 유입되어 가열된다.The exhaust gas transferred from the secondary combustion chamber 30 flows into the heat exchange chamber 50 and is heated.

상기 연결관(60)은 상기 열교환챔버(50)의 열이 상기 유체하우징(10)로 전달되도록 상기 열교환챔버(50)와 유체하우징(10)을 연결한다. 이 때, 상기 연결관(60)은 상기 열교환챔버(50)의 외부 챔버와 유체하우징(10)를 서로 연결하여, 상기 유체하우징(10)의 유체와 상기 열교환챔버(50)의 열의 열교환이 이루어져서 유체가 가열된다.The connection tube 60 connects the heat exchange chamber 50 and the fluid housing 10 so that the heat of the heat exchange chamber 50 is transferred to the fluid housing 10. At this time, the connection pipe 60 connects the outer chamber of the heat exchange chamber 50 and the fluid housing 10 to perform heat exchange between the fluid of the fluid housing 10 and the heat of the heat exchange chamber 50 The fluid is heated.

상기 배기하우징(70)은 상기 열교환챔버(50)에서 이송된 배기가스가 배출된다.The exhaust housing 70 discharges the exhaust gas transferred from the heat exchange chamber 50.

이에 따라, 본 발명에 따른 폐열 회수율이 극대화된 소각 보일러(100)은 2차연소챔버(30)에서 배기가스의 재연소가 이루어져서 배기가스의 연료의 연소효율을 극대화할 수 있고, 열교환챔버(50)에서 배기가스의 열이 유체에 재흡수되어 배기가스의 폐열 회수율을 극대화할 수 있는 장점이 있다.Accordingly, the incineration boiler 100 having the maximized waste heat recovery rate according to the present invention can maximize the combustion efficiency of the fuel of the exhaust gas by re-burning the exhaust gas in the secondary combustion chamber 30, The heat of the exhaust gas is reabsorbed in the fluid, thereby maximizing the waste heat recovery rate of the exhaust gas.

도 3은 본 발명에 따른 2차연소챔버, 열교환챔버, 정체유도챔버를 나타낸 단면도이다.3 is a sectional view showing a secondary combustion chamber, a heat exchange chamber, and a stagnation induction chamber according to the present invention.

도 3에 도시된 바와 같이, 상기 2차연소챔버(30)는 배기가스의 열이 외부로 배출되지 않도록 내주면에 방사상으로 설치되는 내화벽돌(31)을 더 포함할 수 있다.As shown in FIG. 3, the secondary combustion chamber 30 may further include a refractory brick 31 radially installed on the inner circumferential surface so that heat of the exhaust gas is not discharged to the outside.

상기 내화벽돌(31)은 상기 배기가스의 열을 보온하는 역할을 한다. 또한, 상기 내화벽돌(31)의 내부에는 상변화물질이 내장될 수 있다.The refractory bricks 31 serve to heat the heat of the exhaust gas. In addition, a phase change material may be embedded in the refractory brick 31.

또한, 상기 열교환챔버(50)는 내부에 설치되며 상기 2차연소챔버(30)에서 이송된 배기가스가 분할되어 통과하는 다수의 열교환관(51)을 더 포함할 수 있다. 이에 따라, 상기 열교환챔버(50)의 내부에 유입된 유체와 다수의 상기열교환관(51)을 통과하는 배기가스의 열교환이 면접촉에 의해 이루어져서 유체가 가열된다.In addition, the heat exchange chamber 50 may further include a plurality of heat exchange tubes 51 disposed therein and through which the exhaust gas transferred from the secondary combustion chamber 30 is divided and passed. Thus, the heat exchange between the fluid introduced into the heat exchange chamber 50 and the exhaust gas passing through the plurality of heat exchange tubes 51 is performed by surface contact, thereby heating the fluid.

또한, 상기 열교환챔버(50)는 다수의 상기열교환관(51)이 더 구성될 경우, 양단이 막힌 구조로 형성되며, 양단이 각각 상기 열교환관(51)의 양단과 관통 결합된다.When the plurality of heat exchange tubes 51 are further formed, the heat exchange chamber 50 is formed with a closed structure at both ends, and both ends of the tubes are respectively connected to both ends of the heat exchange tube 51.

또한, 상기 폐열 회수율이 극대화된 소각 보일러(100)은 정체유도챔버(80)와, 수위센서(15)와, 연통관(90)을 더 포함할 수 있다.In addition, the incineration boiler 100 having the maximized waste heat recovery rate may further include a stagnation induction chamber 80, a water level sensor 15, and a communicating pipe 90.

상기 정체유도챔버(80)는 상기 열교환챔버(50)와 배기하우징(70) 사이에 설치되어 상기 열교환챔버(50)에서 이송된 배기가스의 정체를 유도한다. 이에 따라, 상기 열교환챔버(50)를 통과하는 배기가스의 유속이 저하되어 배기가스와 유체의 열교환 효율이 좀 더 증가하게 된다.The stagnation induction chamber 80 is installed between the heat exchange chamber 50 and the exhaust housing 70 to induce stagnation of the exhaust gas transferred from the heat exchange chamber 50. Accordingly, the flow rate of the exhaust gas passing through the heat exchange chamber 50 is lowered, and the heat exchange efficiency between the exhaust gas and the fluid is further increased.

상기 수위센서(15)는 상기 유체하우징(10)의 수위를 측정하며, 상기 유체하우징(10)의 수위가 기준 수치 이하일 경우, 상기 유체하우징(10)으로 유체가 유입되도록 유체펌프(미도시)를 작동시킨다.The water level sensor 15 measures the level of the fluid housing 10 and controls a fluid pump (not shown) so that fluid flows into the fluid housing 10 when the level of the fluid housing 10 is below a reference value. .

상기 연통관(90)은 상기 1차연소챔버(20)와 배기하우징(70)을 서로 연결하며, 상기 1차연소챔버(20)에서 발생하는 배기가스가 상기 배기하우징(70)으로 바로 배기되게 한다. 이는 상기 1차연소챔버(20)의 압력이 과도하게 상승하는 것을 방지하려는 것이다.The communicating tube 90 connects the primary combustion chamber 20 and the exhaust housing 70 to each other and allows the exhaust gas generated in the primary combustion chamber 20 to be directly exhausted to the exhaust housing 70. This is to prevent the pressure of the primary combustion chamber 20 from rising excessively.

이 때, 상기 연통관(90)에는 솔레노이드밸브(미도시)가 설치되어 상기 1차연소챔버(20)의 압력이 기준수치 이상이 되는 것을 감지하면 자동으로 개방될 수 있다.At this time, a solenoid valve (not shown) may be installed in the communicating tube 90 to be automatically opened when the pressure of the primary combustion chamber 20 becomes higher than a reference value.

본 발명은 상기한 실시예에 한정되지 아니하며, 적용범위가 다양함은 물론이고, 청구범위에서 청구하는 본 발명의 요지를 벗어남이 없이 다양한 변형 실시가 가능한 것은 물론이다.It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
