It is installed to have a blocking plate to block the pollutants generated during combustion to be discharged to the outside, the door is characterized in that the monitoring window is further provided.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

1 is a view schematically showing a configuration of a boiler according to an embodiment of the present invention.

As shown, the boiler according to the present embodiment has a shape of a hexahedron and has a combustion cylinder 10 inside which combustion occurs, and surrounds the combustion cylinder 10 so as to be spaced apart from the outer surface of the combustion cylinder 10 by a predetermined distance. The outer shell 15 is provided so that the outer surface of the combustion cylinder 10 and the inner wall surface of the outer shell 15 form a space, and includes a water tank 16 including water in the space portion. The water contained in the water tank 16 is heated by receiving heat from the combustion tank 10.

The front wall of the combustion cylinder 10 is provided with a door 12 for injecting waste materials or wood (hereinafter, raw material) into the interior of the combustion cylinder 10, the exhaust gas exhaust port for discharging the combustion gas on the rear wall (14) is provided. The door 12 is pin coupled to the combustion cylinder 10 is rotated about the pin is opened and closed. In addition, the monitoring window 50 is provided at the central side of the door 12. The monitoring window 50 is for monitoring the situation inside the combustion cylinder 10 and is composed of heat-resistant glass. The lower part of the door 12 is provided with a ash tray 30. The ash tray 30 is for discharging ash of the burned fuel from the inside of the combustion cylinder 10, and is installed between the support plate 28 and the bottom surface of the combustion cylinder 10 which will be described later, and the arrow z direction. It is possible to slide in, it is possible to separate and mounted to the combustion cylinder 10 through the sliding movement.

An air supply port 32 is formed at one side of the combustion cylinder 10. The air supply port 32 is a passage through which oxygen necessary for combustion of fuel in the combustion cylinder 10 passes, and adjusts the amount of air passing through to control the amount of heat generated in the combustion cylinder 10. The air supply port 32 as described above is positioned below the side wall of the combustion cylinder 10, and is formed on the side of the combustion cylinder 10 corresponding to the lower side of the support plate 28. The amount of air passing through the air supply port 32 is controlled by the opening and closing mechanism 34, which is an air amount controlling means operated by the controller (24 of FIG. 3). The opening and closing mechanism 34 is located outside the combustion cylinder 10, and is installed spaced apart from the air supply port 32 by a predetermined distance. That is, the opening and closing mechanism 34 is a mechanism for opening and closing the air supply port 32, and is configured to be operated by an electromagnet (46 in FIG. 2). The opening and closing mechanism 34 is fixedly installed on a separate support plate (not shown) spaced apart from the air supply port 32 by a predetermined distance, and the electromagnet (46 in FIG. 2) and the spring (40 in FIG. 2) and the pressure member 42 therein. ) And a housing 36 including an opening and closing plate 44 linearly moving in the direction of an arrow a outside the housing 36. The opening and closing plate 44 moves to the air supply port 32 to close contact with the edge of the air supply port 32 to block the flow of air through the combustion cylinder 10.

On the other hand, the support plate 28 and the blocking plate 48 are provided inside the combustion cylinder 10. First, the support plate 28 is a member positioned horizontally in the lower part of the combustion cylinder 10 and supporting the fuel introduced through the door 12. That is, the support plate 28 is installed at a predetermined height spaced apart from the bottom surface of the combustion cylinder 10, by separating the raw material introduced into the interior through the door 12 from the bottom surface, the air supply port 32 formed in the lower portion of the raw material Air is supplied smoothly from combustion to ensure effective combustion. Therefore, the height of the support plate 28 is configured to be positioned higher than the air supply port (32). In addition, the shape of the support plate 28 is in the form of a lattice so that the raw material does not fall to the bottom surface of the combustion cylinder 10, so that the edge portion of the support plate 28 is sufficiently close to the inner wall of the combustion cylinder 10, the raw material is a support plate ( 28 so as not to fall to the floor through the gap between the edge of the inner wall of the combustion chamber (10).

The blocking plate 48 is configured in the form of an iron plate and is installed below the exhaust port 14. This serves to block the ash generated when the raw material burns and rises due to the heat of combustion to prevent it from exiting the exhaust port 14. In addition, the blocking plate 48 heated by the combustion heat serves as a secondary combustion function of the incomplete combustion gas generated during combustion. That is, the blocking plate 48 is heated to a high temperature by the heat of combustion of fuel burning inside the combustion cylinder 10, and the combustion gas passing in the direction of the arrow b while contacting the heated blocking plate 48 is heated to a high temperature. Secondary combustion occurs by contact with the heated blocking plate 48, whereby incomplete combustion gas is completely burned out by the secondary combustion.

The replenishment water tank 26 is installed in the upper portion of the water tank 16. The replenishment water tank 26 is connected to an external water supply facility to receive water continuously. When water in the water tank 16 is consumed due to the hot water supply, the water in the supplemental water tank 26 is supplied to the water tank 16 to replenish the water in the water tank 16. In addition, an air hole 60 is formed on the top surface of the replenishment water tank 26. The air hole 60 is to maintain the pressure in the replenishment water tank 26 at atmospheric pressure, and to remove the air mixed in the water supplied from the outside to discharge to the atmosphere.

Figure 2 is a view showing the opening and closing mechanism of one of the air amount control means of the boiler according to an embodiment of the present invention.

As shown, the opening and closing mechanism 34 has a housing 36 installed at a position spaced apart from the air supply port 32 by a predetermined distance, and a spring 40 installed so that one side is supported on the inner wall 38 of the housing 36. ), The pressurizing member 42 elastically supported by the spring 40 and linearly moving in the direction of the arrow c and the edge of the air supply port 32 and the edge of the air supply port 32 by close contact with the elastic force, thereby the combustion cylinder 10 It is provided with an opening and closing plate 44 coupled to the front end surface of the pressing member 42 to be sealed. In addition, the electromagnet 46 is provided on the outer side of the pressing member 42 to linearly move the pressing member 42 in the direction of the arrow d. The electromagnet 46 is electrically connected to the controller (24 of FIG. 3), and is magnetized by applying electricity through the controller to open the air supply port 32 by moving the pressure member 42 in the direction of the arrow d. . The pressing member 42 is a member of a conductive material is used to move by the electromagnet 46. In addition, in the state in which electricity is not applied to the electromagnet 46, the opening and closing plate 44 maintains a state in which the air supply port 32 is sealed. That is, since the opening and closing plate 44 is pressed toward the air supply port 32 by the elastic force of the spring 40, air does not pass through the air supply port (32). In this state, when the temperature of the water in the water tank 16 falls, the controller 24 is operated to apply electricity to the electromagnet 46, and the pressure member 42 is spring-loaded by the force induced by the electromagnet 46. The air supply port 32 is opened by moving in the direction of the arrow d against the bearing force of 40). Therefore, the air is supplied into the combustion cylinder 10 to promote combustion, thereby raising the temperature of the water.

3 is a view showing for explaining the operation of the boiler according to an embodiment of the present invention.

As shown, the sensor 52 is installed inside the boiler water tank 16 of the present embodiment. The sensor 52 detects a temperature of water in the water tank 16 and is connected to a controller 24 installed outside the water tank 16. The upper and lower portions of the water tank 16 are provided with pipes 18 and 19 to circulate the heated water or to supply the heated water to a position where heating and hot water are required. The installation position of the supply pipe 18 and the return pipe 19 communicating with the water tank 16 may be installed at any position of the water tank 16. In this embodiment, the supply pipe 18 is connected to the water tank. It was installed in the lower part of (16), and the return pipe 19 was installed in the upper part of the water tank 16. The heated water flowing in the pipes 18 and 19 is pressurized by the pump 20 to circulate while flowing inside the pipe or supplied to a hot water supply facility. The pump 20 is connected to the electric motor 22 driven by the controller 24 to operate under the rotational force from the electric motor 22. That is, the controller 24 connected to the sensor 52 in the water tank 16 compares the temperature set by the user with the temperature of the water at the moment, and if the temperature of the water is lower than the set temperature, the motor By stopping or lowering the rotation of 22, the operation of the pump 20 is stopped or the rotation speed is reduced. When the operation of the pump 20 is stopped or the rotation speed decreases, the water flowing in the pipes 18 and 19 and the water in the water tank 16 are stopped or the flow flow rate is reduced. At the same time, the controller 24 applies electricity to the opening / closing mechanism 34 to operate the electromagnet 46 to open the air supply port 32 to promote the combustion of the raw material burning in the combustion cylinder 10. Let's do it. The heating in the water tank 16 is carried out by the combustion heat promoted while the water in the water tank 16 is stopped without flowing or a small amount of water flows, so that the water temperature in the water tank 16 is raised to finally set the temperature. When reaching, controller 24 rotates motor 22 at normal speed to resume rotation of pump 20 or increase rotation speed. At the same time, the opening and closing mechanism 34 is operated to reduce the amount of air flowing through the air supply port 32. On the contrary, when the water temperature in the water tank 16 rises excessively, the controller 24 operates to bring the opening and closing plate 44 of the opening / closing mechanism 34 close to the air supply port 32 to open the air supply port 32. By reducing the amount of air passing through, the combustion of fuel in the combustion cylinder 10 is suppressed and the water temperature is lowered.

On the other hand, since the replenishment water tank 26 provided in the upper portion of the water tank 16 in order to replenish the water reduced by being supplied to the hot water supply facilities, etc., when the amount of water in the water tank 16 is reduced, Water is supplied from the outside in the direction of the arrow e and supplied to the water tank 16. In addition, the air contained in the water tank 16 and the supplemental water tank 26 is discharged to the atmosphere through the air hole 60.

4 is a view illustrating a blower that is another one of the air amount controlling means applied to the boiler according to an embodiment of the present invention. In addition, the blower mechanism has the same purpose as the opening and closing mechanism described in FIG. 3 and can be replaced with each other according to the use environment.

As illustrated, the blower mechanism 76 includes an air flow passage 72 connected to and communicated with the air supply port 32, and a blower 70 installed inside the air flow passage 72. The blower 70 is supported by the support member 74 in the air flow passage 72 to forcibly blow air to the air supply port 32 side. In addition, the blower 70 is a motor that is electrically connected to and operated by an external controller (24 of FIG. 3), and a fan 78 is installed on the drive shaft.

The operation of the boiler equipped with the blower mechanism 76 configured as described above is similar to that of FIG. 3. That is, when the temperature of the water in the water tank 16 is higher than the set value, the rotation of the blower 70 is stopped or slowed by the control of the controller (24 in FIG. 3), thereby slowing the combustion of the fuel and lowering the temperature of the water. When the water temperature is lower than the set value, the rotation of the blower 70 is increased by the control of the controller (24 in FIG. 3) to promote combustion of the fuel and the water temperature is raised again. The operation of the blower 70 is linked to the operation of the electric motor 22 and the pump 20 is the same as the case of the opening and closing mechanism 34 described above. That is, when the rotation of the blower 70 increases, the rotation of the electric motor 22 and the pump 20 slows down or stops. On the contrary, when the rotation of the blower 70 stops or the rotation speed decreases, the electric motor ( 22) and the rotation of the pump 20 increases, which is controlled by the controller (24 in FIG. 3).

The water heated in the water tank 56 flows in the direction of arrow f1 through the pipe 61a, and passes through the selector valve 66a in the direction of arrow f2. Water then passes through the heating zone 68 and supplies heat to the outside while flowing the pipe 61b. The heating zone 68 means that the hot water is supplied to the outside. The water flowing continuously passes through the switching valve 66b in the direction of the arrow f3 and flows through the pipe 61c, and returns to the water tank 56 through the switching valve 66c in the direction of the arrow f4.

In addition, as described above, the main circulation path is constituted by the first, second, third, and fourth switching valves 66a, 66b, 66c, and 66d operated by the controller 24.

First, the water heated from the water tank 56 starts to flow in the direction of arrow f1, and performs heat exchange while passing through the switching valve 66a in the direction of arrow f2 and passing through the pipe 61b. After the heat exchange, the water continues to flow through the switching valve 66b in the direction of the arrow g3 to the water tank 16. The water flowing into the water tank 16 circulates inside the water tank 16 and then flows through the switching valve 66d in the direction of the arrow h1 and flows into the pipe 63. Subsequently, the circulation is terminated by passing the switching valve 66c in the direction of the arrow h2 and returning to the tank 56. In addition, each switching valve (66a, 66b, 66c, 66d) is operated by a controller and the pressure required for the flow of water is provided using a pump (not shown) installed in the existing boiler (54).

Figure 6 is a view showing for explaining the driving method of the circulation system of the boiler made as described above.

As shown, when the boiler 8 of the present invention is connected to the existing boiler 54, the temperature of the water in the water tank 16 is set by the sensor 52 which senses the temperature of the water in the water tank 16. If lower, the controller 24 operates the ignition device 58 of the existing boiler 54 to operate the boiler 54. At the same time, the motor 23 and the pump 21 are operated and the respective switching valves 66a, 66b, 66c, 66d are controlled to control the flow direction of the water, thereby combining the boiler 8 and the existing boiler 54 of the present invention.
