The water of the hot water storage room is heated by the heat of combustion generated when the fire water is burned in the fire room. In the process of burning the fire water in the fire room, If sufficient oxygen is not supplied from the outside, the ignition is not performed well during the initial ignition process or the thermal power is weak and the combustion heat is very low. Therefore, the air supply pipe from the blower is installed in the interior of the firebox to supply oxygen from the outside.

According to Korean Patent Publication No. 10-0426046, there is provided a fuel cell stack including a warming space, a burner portion, a support for holding the burner portion, a combustion chamber in which the flame of the burner portion is injected, a heat exchanger for covering the combustion chamber with water Wherein the air supplied through the secondary air blower is supplied to the burner unit through the upper air nozzles formed on both side portions of the refractory material and the lower air nozzles formed on both lower portions of the refractory. Burner burning structure of a burner.

In the burner unit combustion structure of the conventional articulated boiler, the upper and lower air nozzles are provided on the lower side of the hallowed space, and oxygen is supplied from the lower portion to the burner unit. Therefore, combustion is carried out by the oxygen supplied from the lower nozzle from the bottom of the loaded fellow, and the lower fellow is burnt down to the ash, and the upper fellow is lowered and burned. At this time, if the boiler stops driving because the current temperature rises above the set temperature of the boiler's heating water, or if it is extinguished by itself or when it is tried to re-ignite according to the user's needs, the vinegar And the residue left over from the nozzle is blocked at the nozzle inlet provided at the lower part, making it difficult to supply the air through the nozzle, so that the recollection is not performed well.

In addition, since the nozzle installed at the lower part feeds air from the lower part to the upper part of the fallowing wood, if it is ignited at the upper part or the lower part of the middle part, it is easy to move to the upper part or the middle part due to the lowered air. The air can not be supplied smoothly, and there is a problem that the air conditioner can not be recycled.

In addition, while the firewood on the lower floor of the firebox is burnt down, the firewood in the middle or upper part of the firebox is heated due to the downward burning, so that the burning does not occur but only the woodpecker is produced. By cooling them, they are entangled so that the medallion or the upper half of the harmonious woods are entangled to form a house. As a result, the harmonics forming the house are agglomerated, so that the respective harmonics can not move downward in time. As a result, in the lower part where ignition is performed, there is a case where ignition is not performed due to insufficient supply of harmonics,

In addition, when the remnant remnants are formed by a wood vinegar or the like, in the conventional lower air supply structure, the harmonics forming the house interfere with the flow of air supplied from the lower part, and the lower air can not be smoothly supplied to the upper part or the middle part There is a problem that even if the recollection is not performed smoothly or is re-ignited, the fire is weak and the digestion occurs immediately.

The air supply member 30 may be welded or fixed by fixing means such as bolts, nuts, or rivets so as to be fixed on the entire surface of the firebox 20.

An air outlet 33 is formed on the door side outer side surface of the air supply member 30. The outlet of the air blowing pipe 32 provided on the side of the door 10 is connected to the air outlet 33, And separated when the door 10 is opened. The blowing pipe 32 is integrally provided with the blower 31 and is fixed to the door 10. When the door 10 is opened, the outlet of the blowing pipe 32 is separated from the blowing port 33. However, when the door 10 is closed, the outlet of the blowing pipe 32 is fitted to the blowing port 33, (Not shown).

In addition, a plurality of nozzle-shaped nozzles 35 are formed on the inner side wall of the air supply member 30 at the side facing the firebox 20. The nozzles 35 are spaced apart from each other in the upper, middle, and lower positions of the air supply member 30 by a predetermined distance in the lateral direction in consideration of the height of the red thread W loaded on the fire chamber 20 .

A through hole 34 is formed in a part of the lower part of the air supply member 30 to penetrate the inside of the air supply member 30. The ignition port 12 is provided in the through hole 34 so as to be openable and closable so that the door 10 is opened from the outside to supply the ignition point W to the harmonics W It functions as a door.

In addition, a grate 21 may be provided in a lower part of the interior of the firebox 20 where the red light W is loaded. The grate 21 is installed so as to smoothly supply the harmonics W when the harmonics W are burned by maintaining the gap between the bottom of the fire box 20 and the harmonics W. In addition, It also acts as a filter to filter out ash and residue. For example, the grate 21 may be manufactured using a square net or a roast tall type in which a plurality of round bars are arranged at regular intervals, and may be installed at the bottom of the firebox 20 and used.

A discharge port (41) is formed in the bottom of the interior of the fire chamber (20) as a passage through which heat of combustion generated during the burning of the harmonious wood (W) escapes and a discharge pipe (40) is connected to the lower end of the discharge port (41). At this time, it is preferable that the discharge pipe 40 is formed to be bent in a 'C' shape when viewed from the side of the boiler, so that the combustion gas (combustion heat) is prevented from rapidly escaping to the outside, Thereby improving the heat exchange efficiency.

In addition, a heat exchange member is provided in the inside of the fellowship boiler so as to supply hot water and heated water to the outside so that water flowing into the boiler can be heated and supplied to the outside.

The heat exchanging member may be composed of a warm-up coil 50, a water jacket 60, or the like.

The water jacket 60 may be provided around the artificial chamber over the entire interior of the housing 1, and in particular, it surrounds the outside of the discharge pipe 40 and the warm-up coil 50. The water in the water jacket 60 is heated by heat exchange with a combustion gas (combustion heat) generated in the firebox and moving to the outside through a discharge pipe, and the heated water can be supplied to the outside as hot water or heating water.

The warming coil 50 can be installed, for example, in the water jacket 60 at the upper portion of the artificial chamber 20, and the water flowing inside the warming coil 50 is heated again by indirect heat exchange with water heated from the water jacket 60 And the warmed water is supplied to the outside.

Hereinafter, the function of the harmony boiler according to the preferred embodiment of the present invention will be described in detail.

The ignition means such as a matchstick or a gas torch can be manually used directly from the outside, and the ignition means such as a gas torch or the like can be used to burn the harmonics W loaded in the firebox 20, A newspaper or the like may be placed in the lower part of the harmonized wood W and the lower part of the transferred felled wood W may be ignited by attaching the fire through the ignition port 12. [

2, the blower 31 is operated so that the outside air is rapidly introduced into the blowing pipe 32, and the air is blown into the blowing pipe 32. In this way, The outside air is moved into the air supply member 30 along the blower pipe 32. At this time, the speed at which the external air is introduced may be adjusted according to the fan speed RPM of the blower 31. The air that has been moved into the air supply member 30 is uniformly distributed to the upper, middle, and lower portions of the air supply member 30 and is supplied into the interior of the fire chamber 20 through the plurality of nozzles 35 formed at the respective positions . As a result, combustion air is uniformly supplied to the whole of the harmonics stacked in the upper, middle, and lower portions of the firebox. Particularly, it is preferable that the nozzle 35 is provided in the form of a hole having an appropriate size or a shape protruding inwardly from the interior of the compartment so that the rapidly introduced air passes through the nozzle 35 and becomes faster due to the pressure difference.

When the air is supplied through the nozzle 35 evenly inside the fire room 20 and the fireworks W are ignited from the lower part by receiving the fire from the outside, smoke and combustion heat are generated during the combustion process. At this time, since the generated smoke and the heat of combustion are to be moved upward, the upper and side portions of the firebox are closed, and the passage communicating with the flue 43 is formed through only the lower exhaust port 41, The air forces the smoke and the heat of combustion downward. At this time, since the fumes moving downward are mostly burned out by the flame of 900 DEG C or more generated at the time of burning the harmonics W, most of the fumes moving along the discharge pipe 40 become combustion heat.

Thus, since the exhaust port 41 is formed in the bottom of the firebox 20, the combustion heat led downward is forcedly guided to the exhaust port 41. The combustion heat is moved along the discharge pipe 40 connected to the exhaust port 41 and moved upward along the flue 43 connected to one end of the discharge pipe 40, And is discharged to the outside through the discharge port 44 provided at the upper end. At this time, the heat of combustion, which is moved by the discharge pipe 40 formed in a 'C' shape, is delayed in moving speed, and a slight delay process is performed inside the discharge pipe 40. In this lagging process, the combustion heat is transferred to the water jacket 60 surrounding the outer side of the discharge pipe 40, and the water inside the water jacket 60 is heated by the transferred combustion heat. That is, the 'C' -shaped discharge pipe 40 is for increasing the heat transfer efficiency. In addition, the water jacket 60 functions as a heat transfer means for supplying heated water to hot water or heating water.

The vinegar, debris, ashes, and the like generated during the burning of the harmonics (W) are partially separated by the discharge pipe (40), which interferes with the flow of the combustion heat moving along the discharge pipe (40) You can knock. Accordingly, the inner portion of the discharge pipe 40 located inside the lower door 42 is opened by opening the lower door 42, and the inside of the discharge pipe 40 exposed when the lower door 42 is opened is periodically cleaned . ≪ / RTI >

Referring to FIG. 5, a harmony boiler according to another embodiment of the present invention will now be described.

FIG. 5 is a view showing the door 10 in an opened state to show the inner configuration of the door 10 of the fellowship boiler according to another embodiment of the present invention.

One side of the air supply member 30 is fixed to the housing 1 with a hinge so that the air supply member 30 installed on the lower side in front of the fire chamber 20 can be opened while the door 10 of the fellowship boiler is opened The locking side can be maintained by fixing means (not shown) such as a door clamp on the opposite side of the portion fixed by the hinge. The air supplied to the air supply member 30 during the combustion of the harmonics W is prevented from leaking to the outside while the air supply member 30 is in the locked state and the handle is provided on one side of the air supply member 30, So that the fastening means of the fastening means can be easily locked or unlocked.

The air supply member 30 may be opened to expose the lower portion of the fire box 20 to the outside when the user wishes to clean the ashes or residue remaining in the lower portion of the fire box 20 after the burning of the harmonics W. [

That is, some of the ashes and residue remaining on the fellow (W) fall down to the discharge pipe 40 through the discharge port 41, but some remain in the lower portion of the firebox 20, It is preferable to clean the ashes and the like accumulated on the bottom of the firebox 20 by opening the air supply member 30. [

Furthermore, the boundary between the lower side of the air supply member 30 and the bottom surface of the flower chamber 20 can be made to coincide with each other. In this way, when cleaning the floor of the firebox (20), an operator can easily handle the residue or residue left on the floor of the firebox (20) by using a cleaning tool.
