Description

화목보일러{Firewood Boiler}Firewood Boiler {Firewood Boiler}

본 발명은 화목보일러에 관한 것으로, 보다 구체적으로는 하부의 화목연소실과 상부의 열교환기가 수직연관으로 연결된 횡형 2패스 구조의 화목보일러에 관한 것이다.The present invention relates to a firewood boiler, and more particularly, to a firewood boiler having a horizontal two-pass structure in which a lower firewood combustion chamber and an upper heat exchanger are connected in a vertical connection.

일반적으로 가정이나 각종 건물, 시설물 등의 난방 내지 온수 공급을 위해 사용되는 보일러는 사용 연료에 따라 화목보일러, 기름보일러, 가스보일러 등이 있다.In general, boilers used for heating or supplying hot water to homes, various buildings, and facilities include firewood boilers, oil boilers, and gas boilers, depending on the fuel used.

기름보일러나 가스보일러는 열효율이 상대적으로 우수할 뿐만 아니라 기름 분사량이나 가스 공급량을 제어하여 연소상태를 일정하게 유지할 수 있어 보일러의 유지 및 관리가 편리하다는 장점이 있으나, 연료비가 고가라는 단점이 있다.Oil boilers and gas boilers have the advantage of relatively high thermal efficiency and control of oil injection or gas supply to maintain a constant combustion state, which makes the maintenance and management of the boiler convenient, but has the disadvantage of high fuel costs.

화목보일러는 화목(장작, 잔목, 폐목 등)을 태워 발생하는 열을 이용하는 것으로, 열효율이 상대적으로 낮고 지속적으로 땔감을 공급하여야 하며 연소 상태의 수시 확인이 필요하다는 단점이 있지만, 그 구조가 간단하고 연료비가 매우 저렴하다는 장점이 있으므로, 아직도 농촌이나 산간지역의 가정이나 시설물 등에서는 널리 사용되고 있다.The firewood boiler uses heat generated by burning firewood (wood, lumber, waste wood, etc.), which has the disadvantage that the thermal efficiency is relatively low, the fuel must be continuously supplied, and the combustion state needs to be checked at any time. Since the fuel cost is very low, it is still widely used in homes and facilities in rural or mountainous areas.

다만, 화목보일러의 이용을 확산시키기 위해서는 구조개선 및 효율적인 제어방식의 도입을 통해 열효율을 향상시키기 위한 방안이 필요한 실정이다.However, in order to spread the use of firewood boilers, there is a need for a method for improving thermal efficiency by improving the structure and introducing an efficient control method.

본 발명의 목적은 열교환기의 구조개선을 통해 화목보일러의 열효율을 향상시키기 위한 것이다.An object of the present invention is to improve the thermal efficiency of the firewood boiler through the structural improvement of the heat exchanger.

본 발명의 다른 목적은 흡기/배기 방식을 개선하여 화목보일러의 열효율을 향상시키기 위한 것이다.Another object of the present invention is to improve the heat efficiency of the firewood boiler by improving the intake / exhaust method.

본 발명의 또 다른 목적은 물 온도에 따라 흡기량이나 배기량을 조절하여 화목보일러의 열효율을 향상시키기 위한 것이다.Another object of the present invention is to improve the thermal efficiency of the firewood boiler by adjusting the intake or exhaust amount according to the water temperature.

On the other hand, a known hot water flow passage (not shown) is formed around the heat exchanger 13 and is connected to the hot water inlet 24a and the hot water outlet 24b.

하우징(11)의 내부에는 화목연소실(12), 열교환기(13), 수직연관(14)을 둘러싸도록 수실(15)이 설치된다. 수실(15)에는 물이 저장되고 난방환수(23a) 및 난방출구(23b)와 연결된다. 수실(15) 내의 물은 화목연소실(12), 수직연관(14), 열교환기(13)와의 열교환에 의해 가열된다.The water chamber 15 is installed inside the housing 11 to surround the firewood combustion chamber 12, the heat exchanger 13, and the vertical pipe 14. Water is stored in the water chamber 15 and is connected to the heating return 23a and the heating outlet 23b. The water in the water chamber 15 is heated by heat exchange with the firewood combustion chamber 12, the vertical pipe 14, and the heat exchanger 13.

배기연관(19)은 하우징(11)의 외부 전면에서 열교환기(13)와 연결되도록 설치된다. 배기연관(19)은 외기 연통과 연결되어 연소가스의 배출경로를 제공한다. 특히, 배기연관(19)에는 배풍기(20)가 설치된다. 배풍기(20)는 열교환기(13)로부터 배기되는 연소가스가 배기연관(19)을 통해 배기되도록 작동한다. 배기연관(19)과 배풍기(20)의 배풍 구조에 대해서는 상세히 후술할 것이다.The exhaust pipe 19 is installed to be connected to the heat exchanger 13 at the outer front surface of the housing 11. The exhaust pipe 19 is connected with the outdoor air communication to provide a discharge path of the combustion gas. In particular, the exhaust fan 19 is provided with a blower (20). The exhaust fan 20 operates to exhaust the combustion gas exhausted from the heat exchanger 13 through the exhaust pipe 19. The ventilating structure of the exhaust pipe 19 and the ventilator 20 will be described later in detail.

도 2a 및 도 2b는 본 발명의 실시예에 따른 화목보일러의 열교환기 구조를 보여주는 횡단면도이다.2A and 2B are cross-sectional views illustrating a heat exchanger structure of a firewood boiler according to an embodiment of the present invention.

전술한 도 1 및 도 2a와 도 2b를 참조하면, 열교환기(13)는 원통형 구조를 가진다. 특히, 열교환기(13)의 내주면과 외주면 중의 적어도 한 곳에는 다수개의 열교환핀(13a)이 형성될 수 있다. 예컨대 도 2a는 열교환기(13)의 외주면에만 열교환핀(13a)이 형성된 경우를, 도 2b는 열교환기(13)의 내주면과 외주면에 모두 열교환핀(13a)이 형성된 경우를 각각 예시하고 있다. 이와 같이 열교환기(13)에 열교환핀(13a)을 형성하게 되면 열교환면적이 증가되면서 열효율이 향상될 수 있다.1 and 2A and 2B described above, the heat exchanger 13 has a cylindrical structure. In particular, a plurality of heat exchange fins 13a may be formed at at least one of the inner circumferential surface and the outer circumferential surface of the heat exchanger 13. For example, FIG. 2A illustrates the case where the heat exchange fins 13a are formed only on the outer circumferential surface of the heat exchanger 13, and FIG. 2B illustrates the case where the heat exchange fins 13a are formed on both the inner and outer circumferential surfaces of the heat exchanger 13. When the heat exchange fins 13a are formed in the heat exchanger 13 as described above, the heat exchange area may be increased and thermal efficiency may be improved.

또한, 열교환기(13)는 도 1에 도시된 바와 같이 내부에 지그재그판(13b)이 형성될 수 있다. 지그재그판(13b)은 열교환기(13) 내부를 따라 소정의 간격으로 지그재그 형태로 배치되어 열교환기(13)를 통과하는 연소가스의 배출경로를 늘리게 된다. 지그재그판(13b)은 예컨대 원통형의 열교환기(13)를 횡단면상에서 바라봤을 때 반원 형상으로 번갈아 형성되거나 삼분원 또는 사분원이 번갈아 형성될 수 있다.In addition, the heat exchanger 13 may have a zigzag plate 13b formed therein as shown in FIG. 1. The zigzag plate 13b is arranged in a zigzag form at predetermined intervals along the inside of the heat exchanger 13 to increase the discharge path of the combustion gas passing through the heat exchanger 13. The zigzag plate 13b may be alternately formed in a semicircular shape when the cylindrical heat exchanger 13 is viewed in a cross-sectional view, or may be alternately formed in three or four quadrants.

도 1과 도 3에 도시된 바와 같이, 열교환기(13)와 연결된 배기연관(19)에는 수액배출구(21)가 설치된다. 수액배출구(21)는 응축수나 목초액 등의 수액을 외부로 배출시키기 위한 일종의 드레인(drain) 밸브이다. 이때 수액의 배출이 원활히 이루어지도록 열교환기(13)는 수액배출구(21) 쪽으로 하향 경사지도록 형성되는 것이 바람직하다. 경사각은 대략 10도 내외이다. 이와 같이 열교환기(13)를 하향 경사지게 형성하여 수액 배출이 원활히 이루어지면 수액이 열교환기(13)의 내부에 누적되어 열교환 능력이 저하되는 것을 방지할 수 있다.As shown in Fig. 1 and 3, the fluid outlet 21 is provided in the exhaust pipe 19 is connected to the heat exchanger (13). The sap discharge port 21 is a kind of drain valve for discharging sap such as condensed water or wood vinegar to the outside. At this time, the heat exchanger 13 is preferably formed to be inclined downward toward the sap discharge port 21 so that the sap is smoothly discharged. The inclination angle is about 10 degrees. As such, when the heat exchanger 13 is inclined downward to smoothly discharge the sap, the sap accumulates inside the heat exchanger 13 to prevent the heat exchange capacity from being lowered.

하우징(11)의 외부 후면에는 열교환기(13)와 연결되는 청소구(18)가 설치된다. 청소구(18)는 열교환기(13) 내부를 청소하기 위한 통로로, 예컨대 플랜지(flange) 타입으로 열교환기(13)와 연결될 수 있다.The cleaning rear surface 18 connected to the heat exchanger 13 is installed at the outer rear surface of the housing 11. The cleaning tool 18 is a passage for cleaning the inside of the heat exchanger 13, and may be connected to the heat exchanger 13 in a flange type, for example.

도 3은 본 발명의 실시예에 따른 화목보일러의 배풍 구조를 보여주는 측단면도이다.Figure 3 is a side cross-sectional view showing the air blowing structure of the firewood boiler according to an embodiment of the present invention.

도 1과 도 3을 참조하면, 배기연관(19)은 T자형 구조를 가진다. 즉, 배기연관(19)은 측부(19a)에서 열교환기(13)와 연결되고, 하부(19b)에 배풍기(20)가 설치되며, 상부(19c)를 통해 외기 연통(도시생략)과 연결된다. 배기연관(19)의 측부(19a)와 열교환기(13)의 연결은 플랜지 타입을 이용할 수 있다. 배풍기(20)는 배기연관(19)의 하부(19b) 쪽에 위치하되, 배기연관(19)의 내부에 삽입되지 않고 외부에 위치한다. 이와 같이 배풍기(20)를 배기연관(19)의 외부에 두면 부식이나 변형 등의 내구성 문제를 해결할 수 있다. 배풍기(20)는 배풍관(20a)을 포함한다. 배풍관(20a)은 배기연관(19)보다 단면적이 작은 파이프 형태로서, 배기연관(19)의 하부(19b)에 용접되며 배기연관(19)의 내부로 삽입되어 배기연관(19)의 측부(19a)와 수직으로 위치한다.1 and 3, the exhaust pipe 19 has a T-shaped structure. That is, the exhaust pipe 19 is connected to the heat exchanger 13 at the side portion 19a, the air blower 20 is installed at the lower portion 19b, and is connected to the outside air communication (not shown) through the upper portion 19c. . The connection between the side portion 19a of the exhaust pipe 19 and the heat exchanger 13 may use a flange type. Ventilator 20 is located on the lower side (19b) side of the exhaust pipe 19, the outside is not inserted into the exhaust pipe (19). In this way, if the exhaust fan 20 is placed outside the exhaust pipe 19, durability problems such as corrosion and deformation can be solved. The exhaust fan 20 includes an exhaust pipe 20a. The exhaust pipe 20a is a pipe having a smaller cross-sectional area than the exhaust pipe 19, and is welded to the lower portion 19b of the exhaust pipe 19 and inserted into the exhaust pipe 19 so as to have a side portion of the exhaust pipe 19. Perpendicular to 19a).

특히, 배풍관(20a)은 벤츄리관(ventury tube)일 수 있다. 즉, 배풍관(20a)의 중앙 부분이 가늘게 형성되고 이 부분이 배기연관(19)의 측부(19a) 쪽에 위치하게 된다. 따라서 열교환기(13)와 연결된 배기연관(19)의 측부(19a)로부터 배출되는 연소가스는 배기연관(19)의 상부(19c)와 배풍관(20a) 상부의 상대적으로 좁은 공간을 지나면서 유속이 빨라지게 되어(베르누이 원리) 외기 연통으로의 배기가 원활히 이루어진다.In particular, the exhaust pipe 20a may be a venturi tube. That is, the central portion of the exhaust pipe 20a is thinly formed, and this portion is positioned on the side portion 19a of the exhaust pipe 19. Therefore, the combustion gas discharged from the side portion 19a of the exhaust pipe 19 connected to the heat exchanger 13 passes through a relatively narrow space above the upper portion 19c of the exhaust pipe 19 and the upper portion of the exhaust pipe 20a. This speeds up (Bernui principle), so that the exhaust air is smoothly vented.

이와 같이, 본 발명의 화목보일러(10)는 기존에 주로 이용되는 송풍 구조 대신에 배풍 구조를 이용한다. 따라서 열교환기(13)로부터 배기되는 연소가스가 원활히 배기되도록 함으로써 결국에는 화목연소실(12)로 흡기되는 공기공급이 원활하도록 돕는다.As such, the firewood boiler 10 of the present invention uses an air blowing structure instead of a conventional air blowing structure. Therefore, the combustion gas exhausted from the heat exchanger 13 is smoothly exhausted, thereby helping to smoothly supply the air inhaled into the firewood combustion chamber 12.

배기연관(19)과 인접한 하우징(11)의 상단부에는 온도센서(22)가 설치된다. 온도센서(22)는 수실(15)의 물 온도를 측정하기 위한 것이다. 한편, 제어기(도시생략)는 온도센서(22)와 배풍기(20)에 전기적으로 연결되며, 온도센서(22)가 측정한 수실(15)의 물 온도에 따라 배풍기(20)의 풍량을 조절한다.The temperature sensor 22 is installed at the upper end of the housing 11 adjacent to the exhaust pipe 19. The temperature sensor 22 is for measuring the water temperature of the water chamber 15. On the other hand, the controller (not shown) is electrically connected to the temperature sensor 22 and the exhaust fan 20, and adjusts the air volume of the exhaust fan 20 according to the water temperature of the water chamber 15 measured by the temperature sensor 22. .

또한, 연료투입구(16)에는 공기조절댐퍼(17)가 설치된다. 공기조절댐퍼(17)는 열림량을 변동시켜 화목연소실(12)로 흡기되는 공기의 흡기량을 조절하는 수단이다. 공기조절댐퍼(17)도 제어기에 전기적으로 연결되며, 제어기가 수실(15)의 물 온도에 따라 공기조절댐퍼(17)의 열림량을 조절할 수 있다.In addition, the air inlet 16 is provided with an air control damper 17. The air control damper 17 is a means for controlling the intake amount of air taken into the firewood combustion chamber 12 by varying the opening amount. Air control damper 17 is also electrically connected to the controller, the controller can adjust the opening amount of the air control damper 17 according to the water temperature of the water chamber (15).

도 4는 본 발명의 실시예에 따른 화목보일러에서 물 온도에 따른 흡기량 및 배기량의 조절 관계를 보여주는 그래프이다. 도 4의 그래프는 온도센서(22)에서 측정한 수실(15)의 물 온도(T)와 배풍기(20)의 풍량 또는 공기조절댐퍼(17)의 열림량(A) 간의 관계를 나타낸다.Figure 4 is a graph showing the relationship between the intake and exhaust volume according to the water temperature in the firewood boiler according to an embodiment of the present invention. The graph of FIG. 4 shows the relationship between the water temperature T of the water chamber 15 measured by the temperature sensor 22, the air volume of the exhaust fan 20, or the opening amount A of the air control damper 17. As shown in FIG.

보일러 가동 초기에 소정의 물 온도(T1)까지는 배풍기(20)의 풍량 또는 공기조절댐퍼(17)의 열림량을 최대치(A1)로 설정할 수 있다. 점점 물이 가열되면서 온도가 올라가면 그에 반비례하여 배풍기(20)의 풍량 또는 공기조절댐퍼(17)의 열림량을 감소시킨다. 이와 같이 보일러의 물 온도에 배풍기(20)의 풍량이나 공기조절댐퍼(17)의 열림량이 연동되도록 함으로써 화목보일러(10)의 효율을 높일 수 있다.Up to the predetermined water temperature T1 at the beginning of the boiler operation, the air volume of the air blower 20 or the opening amount of the air control damper 17 may be set to the maximum value A1. As the temperature is raised while the water is gradually heated, the amount of air of the exhaust fan 20 or the amount of opening of the air control damper 17 is reduced. As such, the air volume of the air blower 20 and the opening amount of the air control damper 17 are linked to the water temperature of the boiler, thereby increasing the efficiency of the firewood boiler 10.
