Hereinafter, a heating medium boiler 101 according to an embodiment of the present invention will be described with reference to FIGS. 1 to 5. FIG.

1 to 5, a heating medium boiler 101 according to an embodiment of the present invention includes a cylindrical body 200, a burner 200, a body housing 400, a turning guide plate 300, And a thermal oil.

The heating medium boiler 101 according to an embodiment of the present invention includes a circulation pump 700, a gate valve 750, a heating medium oil tank 800, a heating medium oil supply pipe 850, a heat exchanger 500, 900).

The heat medium boiler 101 according to an embodiment of the present invention includes an oil supply pipe 890, a replenishing port 860, a level gauge 870, a circulation pipe 680, a discharge pipe 670, an inlet pipe 610 ), And a connection pipe 650.

The combustion gas generated by combustion of air and a combustible material inside the cylindrical body 200 stays on the upper side of the cylindrical body 200 and transfers thermal energy to the thermal oil to be described later. When the temperature is lowered, And then discharged through the heat exchanger 500, which will be described later.

The burner 250 is coupled to one side of the cylindrical body 200. The burner 250 mixes air and a combustible material into the inside of the cylindrical body 200, and blows and ignites the mixture.

Specifically, the burner 250 may be installed on one side of the cylindrical body 200 connected to the heat exchanger 500.

Further, in an embodiment of the present invention, the burner 250 may use at least one of light oil, heavy oil, gas, and wood pellets as fuel.

The fuselage housing (400) surrounds the cylindrical body (200). At this time, the inner peripheral surface of the body housing 400 and the outer peripheral surface of the cylindrical body 200 are spaced apart to form a heating space. Thus, the heat medium oil is heated in the heating space between the body housing 400 and the cylindrical body 200.

Also, in one embodiment of the present invention, the heat medium boiler 101 can heat the body housing 400 with a heat insulating material to further increase thermal efficiency.

The turning guide plate 300 is installed between the outer peripheral surface of the cylindrical body 200 and the inner peripheral surface of the body housing 400. That is, the turning guide plate 300 is installed in the heating space.

4, the rotation induction plate 300 is fixed to the outer circumferential surface of the cylindrical body and the inner circumferential surface of the body housing, and the rotation induction plate 300 is formed in such a manner that the heat medium oil surrounds the outer circumferential surface of the cylindrical body 200, And guide the movement of the heat medium oil to move.

Further, as shown in Fig. 6, the orbiting guide plate 300 has a shape inclined to one side so that the heat medium oil can swing in the same direction. That is, the turning guide plate 300 has a spiral structure.

For example, the inclination angle? Of the turn guide plate 300 is in the range of 1.7 to 1.8 degrees. The distance between the turning guide plates 300 is in the range of 90 mm to 100 m, and the thickness t of the turning guide plates is in the range of 5 mm to 7 mm. The distance h between the outer peripheral surface of the cylindrical body 200 and the inner peripheral surface of the body housing 400 is within a range of 45 mm to 550 mm. This is a numerical value designed to enable the heat medium oil to efficiently receive heat energy from the cylindrical body 200 while swirling in accordance with the guide of the turn guide plate 300.

The heat medium oil circulates through the heating space along the orbiting induction plate 300 to receive heat energy generated by the cylindrical body 200 and heat the heat.

In one embodiment of the present invention, the heating medium boiler 101 may use synthetic oil-based oil as a heat medium flow path. The oil of the synthetic oil system includes phenyl ether, polyphenyl, arylalkane, and alkbenzene. These oils have excellent thermal oxidation stability, low vapor pressure, and excellent corrosion resistance. In addition, the above-described thermal oil may be used at a temperature within the range of minus 40 degrees Celsius to 350 degrees Celsius.

The circulation pump 700 provides power for circulating the heat medium oil between the heating space and the heat application site.

The circulation pipe 680 connects the circulation pump 700 with the heating space between the outer circumferential surface of the cylindrical body 200 and the body housing 400. That is, the heat medium oil accumulated in the heating space is moved along the circulation pipe 680 by the circulation pump 700. The heat medium oil is discharged to the discharge pipe 670 by the circulation pump 700 and directed to the heat application place.

The heating medium oil tank 800 stores the heating medium oil. The heat medium oil tank 800 is connected to the body housing 400 through a heat medium oil supply pipe 850.

In addition, the thermal oil tank 800 may function as a buffer for absorbing the expansion when the thermal oil is expanded due to heating, in addition to simply storing the thermal oil.

The oil supply pipe 890 is connected to the upper portion of the thermal oil tank 800 to drain a part of the thermal oil stored in the thermal oil tank 800 to the outside when overflow occurs due to the expansion of the thermal oil.

The level gauge 870 displays the stored water level of the heat medium oil stored in the heat medium oil tank 800 so that it can be visually confirmed.

The replenisher 860 is used to replenish the lost heat oil naturally or in the course of circulating the heating space and the heat source.

The heat exchanger 500 is connected to a lower portion of one side of the cylindrical body 200, and the combustion gas discharged from the cylindrical body 200 moves to the heat exchanger 500.

In one embodiment of the present invention, the combustion gas discharged from the cylindrical body 200 and the relatively low-temperature heat medium oil, which has been heated in the heat application place, are heat-exchanged with each other.

Specifically, the heat exchanger 500 includes a plurality of heat exchange pipes 510 through which the combustion gas discharged from the cylindrical body 200 moves, a path through which the heat medium oil moves in contact with the heat exchange pipe 510, And may include a partition wall portion 550. That is, the partition part 500 is arranged in a zigzag pattern so that the heat medium oil moves in a staggered fashion and contacts the heat exchange pipe 510.

The heat medium oil moves zigzag by the partition wall portion 550, and contacts the heat exchange pipe 510 to receive thermal energy from the combustion gas discharged from the cylindrical body 200.

In addition, the heat medium oil having passed through the heat application source flows through the inlet pipe 610 and is directed to the heat exchanger 500.

The gate valve 750 may be installed in at least one of the inlet pipe 610 and the discharge pipe 670.

The gate valve 750 can block the flow of the heat medium oil. Specifically, the gate valve 750 closes the inlet pipe 610 and the discharge pipe 670 according to the maintenance of the circulation pump 700 and various piping, or the like, thereby blocking the flow of the heat medium oil.

The connection pipe 650 moves the combustion gas discharged from the cylindrical body 200 and the heat medium oil that has undergone heat exchange in the heat exchanger 500 to a heating space between the inner peripheral surface of the body housing 400 and the outer peripheral surface of the cylindrical body 200 .

The chimney 900 discharges the combustion gas passing through the heat exchanger 500 into the atmosphere. The chimney 900 assists the combustion gas moving up and down to be smoothly discharged to the atmosphere.

With such a construction, the heating medium boiler 101 according to an embodiment of the present invention can be easily cleaned and maintained, and durability and heat transfer efficiency can be improved.

Specifically, since the arrangement return pipe is not provided inside the cylindrical body 200, which is a combustion chamber, the problem caused by the scale occurring in the pipe can be fundamentally eliminated.

Further, since the combustion gas does not directly come into contact with the pipe through which the heat medium oil flows in the cylindrical body 200, the corrosion by the combustion gas can be fundamentally eliminated.

In addition, the heat medium boiler 101 can secure a wide heat transfer area and improve the heat transfer efficiency.

In addition, the waste heat can be recovered through the heat exchanger 500 to further improve the thermal efficiency.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art. will be.
