The combustion chamber 20 and the heat exchange chamber 30 are connected to each other by the upper and lower connecting ducts 40 and the upper portion of the other side of the heat exchange chamber is connected to the exhaust port 50. The flame and the exhaust gas of the combustion chamber are connected to the combustion chamber The connecting duct 20, the connecting duct 40, the heat exchanging chamber 30, and the exhaust port 50 in a zigzag manner.

The combustion chamber 20 has a heat-exchanging pipe 22a passing through the combustion chamber at right angles to the center of the combustion chamber 20 and circulating the water in the water storage chamber to form a fuel receiving portion 22 spaced back and forth, So that the upper combustion space 21a and the lower combustion chamber 21b are divided vertically.

At this time, in the fuel receiving unit 22, the heat exchange pipes 22a are spaced apart from each other so that the combustion air is smoothly supplied, the fuel such as helmet or briquettes is placed on the heat exchange pipe 22a, The fuel is gradually burned and falls down to contact with the heat exchange pipe at the lower position to perform a sufficient heat exchange, and the fuel is dropped into the lower flue gas recirculation (21b) in a completely combusted ash state, .

The heat exchange pipe 22a of the fuel receiving unit is preferably formed in a three-column structure in which the heat exchange pipes 22a are vertically shifted from each other.

The opening and closing doors 60 and 60 'of the combustion chamber 20 and the heat exchange chamber 30 are coupled to each other by a double structure on the entire surface of the projecting portions 24 and 34 protruding forward of the outer housing. The connection recess portion 63 is formed along the rim between the outer bent portion 61 and the heat insulating portion 62 filled with the heat insulating material to be inserted into the rim of the protruding portions 24 and 34, The opening and closing doors 60 and 60'include an opening and closing operation port 65 connecting a guider 68 moving back and forth along a hinge 66 on the side and a pair of guide rods 67 provided on the side surface of the protrusion, So that the door can be opened and closed by forward and backward movement and leftward and rightward rotation.

Here, the opening and closing doors 60 and 60 'are formed in a double structure having a heat insulating portion to increase airtightness, reduce leakage of the heat source to the outside after combustion of the fuel, and improve safety of the boiler, .

The opening and closing door 60 of the combustion chamber is provided with an auxiliary door 69 forming an air window 69a at the center to supply combustion air to the combustion chamber.

The air tube 25 is inserted into the combustion chamber so as to supply combustion air to both sides of the combustion chamber on both sides of the opening and closing door of the combustion chamber 60. The air tube 25 is provided with at least one air discharge hole 25a Or more.

Further, the auxiliary door 69 of the opening / closing door is separated, and a petroleum ignition combustion device (not shown) is installed in the air window 69a to be used as a fuel ignition device, or even when fuel is completely burned at night, It may be configured to be used as a combustion device.

The heat exchange pipe (30) is arranged in the heat exchange chamber (30) so that the heat exchange pipe (32) passing through the water storage room through the water storage room is heat exchanged. The heat exchange pipe (32) The heat exchange pipe is contacted to the upper part from the lower part to the upper part several times, and at the same time, heat exchange is performed while moving along the longitudinal direction of the heat exchange chamber.

The forward / reverse motor drives the water temperature of the water storage chamber 11 (Not shown). When the heating water falls below a set temperature (about 60 ° C), the normal / reverse motor 55 automatically opens the opening / closing plate to burn the fuel in the combustion chamber, When the temperature rises above the set temperature (about 60 ° C), the opening / closing plate is automatically closed to stop the burning of the fuel in the combustion chamber, so that the heating water temperature of the water storage chamber 11 is automatically maintained at 60 to 90 ° C.

The reference numeral 5 denotes a handle.

Hereinafter, the operation and operation of the present invention will be described.

First, the opening / closing door 60 in the front of the combustion chamber 20 is opened.

Then, fuel such as wood, briquettes or the like is placed on the fuel receiving part 22 in the combustion chamber 20, and then the fuel is ignited and burned.

At this time, since the heat exchange pipe 22a through which the water stored in the water storage chamber of the outer housing 10 is circulated while passing through the combustion chamber in left and right directions is spaced back and forth and up and down Sufficient air is supplied between the fuels so that the combustion efficiency is excellent.

Further, the auxiliary door 69 provided at the center of the opening / closing door 60 of the combustion chamber is opened to sufficiently supply the combustion air into the combustion chamber at the initial stage of combustion of the fuel through the air window 69a, Even if the auxiliary door is closed to prevent the leakage of the fuel into the combustion chamber, the combustion air is uniformly supplied to the inside of the combustion chamber through the air discharge hole 25a of the air tube 25 inserted into both sides of the combustion chamber from both sides of the opening / closing door 60, So that the combustion efficiency of the fuel cell is excellent.

The heat source generated by burning the fuel in the combustion chamber 20 as described above is the heat source of the water storage chamber circulated through the heat exchange pipe in direct contact with the heat exchange pipe 22a forming the fuel receiving portion 22, Exchange is performed.

Particularly, since the heat exchange pipes 22a of the fuel receiving part are formed in a large number of rows and columns so as to be offset from each other while being spaced back and forth, the fuel is gradually burnt and falls down to contact the heat exchange pipe at the lower position, And is completely burnt as it is in the ash state and drops to the bottom ash receiver 21b.

As described above, since the heat source of the combustion chamber fuel directly contacts the heat exchange pipe 22a of the fuel receiving section, heat exchange is performed and the outer wall 20a outside the combustion space portion 21a of the combustion chamber is surrounded by the heating water And then discharged to the heat exchange chamber (30) through the connecting duct (40).

The heat source discharged to the heat exchange chamber 30 is in contact with the heat exchange pipe 32 through which the water in the water storage chamber circulates while passing through the heat exchange chamber 30 in the left and right direction. Since the heat sources are arranged to be offset from each other in the heat exchange chamber 30 so as to be offset from each other, the heat source contacts the upper portion of the heat exchange pipe several times from the bottom to the top and moves along the longitudinal direction of the heat exchange chamber, .

At this time, the outer wall 30a outside the heat exchange chamber 30 also surrounds the heating water, so that the heat exchange is carried out between the outer wall 30a and the outside wall through the exhaust port 50 on the other side of the heat exchange chamber 30.

That is, according to the present invention, in addition to the structure in which the heat source that burns the fuel performs heat exchange with the heating water outside the combustion chamber 20 and the heat exchange chamber 30, the heat exchange pipe 22a is in direct contact with the heat exchange pipe 22a forming the fuel- The heat exchange efficiency can be greatly improved while preventing external heat loss by a structure in which heat exchange is performed while passing through the heat exchange pipe 32 inside the heat exchange chamber 30, .

In the present invention, since the combustion of the fuel in the combustion chamber and the heat exchange with the heating water stored in the water storage chamber 11 outside the combustion chamber 20 and the heat exchange chamber 30 are performed as described above, the heating water is heated, When the heating water temperature rises above the set temperature (about 90 ° C), the normal / reverse motor 55 is activated by the sensing operation of the detection sensor (not shown) to rotate the opening / closing plate 52 inside the air outlet, It will be done.

That is, when the heating water temperature rises above the set temperature, the exhaust port 52 is blocked to stop the burning of the fuel in the combustion chamber 20, and the heat source is prevented from being discharged to the outside through the exhaust port, thereby minimizing the heat loss.

In this state, when the heating water is lowered to a set temperature (about 60 DEG C) or less, the forward / reverse motor 55 is operated again by detecting the detection sensor (not shown) to rotate the opening / closing plate 52 inside the air outlet, The temperature of the heating water is automatically maintained at 60 to 90 占 폚 by repeating the operation of burning the fuel in the combustion chamber 20 again by opening the burner 50 so that the fuel efficiency and energy efficiency are further increased.

The boiler of the present invention is characterized in that the opening and closing doors 60 and 60 'coupled to the combustion chamber 20 and the projections 24 and 34 on the front of the heat exchange chamber 30 have a double- So as to further prevent the heat loss from being absorbed by the outside.

In the boiler of the present invention, when hot water other than the heating water is to be used, water is circulated through the hot water pipe 70 wound around the water storage chamber 11 of the outer housing 30, It is collected and used as hot water.

The boiler of the present invention opens the opening and closing doors 60 and 60 'for reprocessing and cleaning the combustion chamber 20 and the heat exchange chamber 30. The opening and closing doors 60 and 60' The opening and closing doors 60 and 60 'are pulled forward so as to guide the guider 68 of the opening and closing operation tool 65 to the front along the pair of guide rods 67, So that the coupling concave portion 63 of the opening / closing door is moved away from the projecting portions 24 and 34, and then rotated by the hinge 66 to open.

When the opening and closing doors 60 and 60 'are to be closed again, the opening and closing doors 60 and 60' are rotated by the hinges and then the opening and closing doors 60 and 60 ' The guiding member 68 of the operating member 65 is guided rearward along the pair of guide rods 67 to close the coupling recessed portion 63 of the opening and closing member in a state of being inserted into the projecting portions 24 and 34 will be.
