More specifically, the opening and closing door 111 is provided on one side and the combustion chamber 120 provided with an eccentric shaft in the housing 110 in which water is embedded along the inner surface to combust fuel. The combustion chamber 120 is located in the direction of the door 111, the central axis is eccentric with the housing 110, so the distance for charging the fuel is reduced by the length of the central axis is eccentric, it is easy to charge the fuel.

That is, since the combustion chamber 120 is close to the opening and closing door 111, fuel charging is easy. Here, the opening and closing door 111 may be installed in the heat prevention plate (not shown) to prepare for safety accidents. It is preferable that the housing 110 is cylindrical in its inside, and its outer part is preferably substantially polygonal or cylindrical.

In addition, the side of the housing 110 is provided with a heating return port (114 116) and the non-broadcast outlet (117, 118). Water flows into the heating return ports 114 and 116 and the water flows out through the hard broadcast exits 117 and 118. The heating return ports 114 and 116 and the non-broadcast outlets 117 and 118 are connected to pipes in the lower floor, such as an office or a house, to be heated.

The fuel insertion unit 130 is preferably installed inclined so that the opening and closing door 111 side is high and the combustion chamber 120 side is low.

Therefore, when the fuel is injected into the opening / closing door 111, the injected fuel slides into the combustion chamber 120 along the inclined surface of the fuel insertion unit 130.

In addition, the fuel inserting unit 130 tilted upwards has a shorter angle between the user and the handle as much as the inclination of the user when the user opens and closes the handle to insert fuel such as coal, coke, firewood, and the like. It can reduce the bending motion and facilitate the opening and closing.

In addition, the combusted ash of solid fuel such as coal in the combustion chamber 120 is loaded in the ash tray 140 located below the combustion chamber, and the user shakes the ash evenly to load coal in the ash tray 140. It is preferable to form the protruding portion 151 on the upper portion of the supporting stall 150.

The protrusion 151 may be evenly loaded on the ash tray 140 when the ash loaded on the upper part of the protrusion 151 shakes the left and right sides of the protrusion 151. Here, the rostol 150 is interposed in the combustion chamber 120 and the ash tray 140. The ash tray 140 pulls the ash tray 140 toward the user side to remove the ash by separating it from the coal boiler 100.

In addition, it is preferable that the cleaning tool 155 is further provided on the front portion of the fuel loaded on the rostol 150. After the fuel is combusted, materials other than ash, that is, iron components contained in the fuel solidify by high heat to become solid particles. The solid particles can be easily removed by the user through the cleaning tool 155.

Here, the cleaning tool 155 may be prepared for a safety accident by installing a heat prevention plate like the opening and closing door 111.

In addition, the upper outer peripheral surface of the combustion chamber 120 is preferably provided with a spirally enclosed pipe (160). The pipe 160 is connected to the cold water supply pipe 161 on one side and the hot water discharge pipe 163 on the other side. Here, the other side of the cold water supply pipe 161 protrudes to the upper portion of the housing 110 and water is introduced.

In addition, the other side of the hot water discharge pipe 163 protrudes to the upper portion of the housing 110, the water is discharged through the hot water discharge pipe 163. Water is introduced into the cold water supply pipe 161 to discharge the water in the hot water discharge pipe 163.

Here, the water of the pipe 160 may be indirectly heated with water in the housing 110 and discharged into a water pipe such as a toilet to be used as hot water. Hot water is discharged through the hot water discharge pipe (163).

In addition, the pipe 160 having a built-in water that is changed from cold water to hot water by heat transfer may receive more heat transfer as the length of the pipe being indirectly heated and the size of the outer diameter are larger.

However, the optimum length of the pipe 160 does not increase the external volume of the coal boiler 100 equipped with the combustion chamber 120, the fuel insertion unit 130, and the cleaning tool 155 in the housing 110. for,

When the height of the coal boiler 100 is approximately 1200mm and the diameter of the combustion chamber 120 is approximately 300mm, the length of the pipe 160 is approximately 30000mm and the thickness is preferably about 0.8mm, but not limited thereto. It doesn't happen.

Here, the outer diameter of the pipe 160 is preferably about 13 mm in order to make the length 30000 mm, but is not limited thereto.

The water contained in the housing 110 rises in temperature due to heat generated in the combustion chamber 120. Elevated temperature water is a convection phenomenon and the higher temperature water rises above the inner surface of the housing. Therefore, it is more preferable that the pipe 160 is positioned above the housing 110. The pipe 160 located on the upper side has an advantage of rapidly heating hot water than the pipe located on the lower side.

In addition, the through tube 170 may be further provided. The through tube 170 is positioned at an upper portion of the housing 110, and both ends thereof are connected to the combustion chamber so that water embedded in the inner surface of the housing flows. Since the through tube 170 has a large area in contact with the combustion chamber 120, the thermal conductivity becomes high, and thus the hot water may be rapidly heated. Here, the through pipe 170 is preferably provided with one or more.

The through-pipe 170 receiving the heat is more the number, the larger the size of the cross-sectional area receives more heat is, of course. However, for the optimal size not to increase the sheath volume of the coal boiler 100 equipped with the combustion chamber 120, the fuel insertion unit 130, and the cleaning tool 155 in the housing 110,

When the height of the coal boiler 100 is approximately 1200mm and the diameter of the combustion chamber 120 is approximately 300mm, the through pipes 170 are five, the thickness is approximately 4mm, and the cross-sectional area thereof is 32 mm 2. But it is not limited thereto. In addition, the through tube 170 may be positioned horizontally with the ground, or may be formed at an angle with the ground.

In addition, it is preferable to include a temperature controller 175 so that the blower 173 can be controlled by a set temperature so that fuel is continuously burned and the housing 110 is not overheated. The blower 173 may be equipped with a safety net (not shown) to prevent various foreign substances from being sucked. In addition, it is preferable that the cover plate (not shown) of the blower 173 is detachable, and this ease of detachment facilitates inspection of the blower 173.

In addition, a damper (not shown) may be installed and adjusted so that the high heat of the burned fuel is not discharged to the outside of the flue (smoke passage) by the wind pressure of the blower 173. In this case, the year is preferably L-shaped. The L-shaped flue prevents sparks from coming out of the flue when burning fuel such as coal.

When the fuel is burned and the water in the housing 110 is heated, the thermometer 180 may check the temperature of the heated water in front of the coal boiler 100.

In addition, the monitoring device 190 for observing the combustion state of the fuel may be further provided. The monitoring device 190 is formed such that the angle of the horizontal plane is inclined upward, as in the fuel insertion unit, so that the user can see the combustion chamber without having to bend the body when the user perceives the inside of the combustion chamber.
