Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a boiler unit having a waste heat recycling structure,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a boiler apparatus for heating, and more particularly, to a boiler apparatus for heating a boiler apparatus such as a hearth furnace to a double combustion structure to increase the combustion efficiency of fuel such as briquettes, The present invention relates to a boiler system having a waste heat recycling structure capable of recycling waste heat that is discharged to the outside when the boiler system is operated so that waste heat can be maintained as heat for indoor heating as much as possible to enhance heating efficiency.

In the case of indoor use such as a conventional hypothetical restaurant, the combustion vessel is sealed and the communication is connected to the boiler to exhaust the combustion gas outdoors.

However, since such a structure exhausts the high-temperature combustion gas directly to the outside air, most of the combustion heat generated through combustion is exhausted to the atmosphere, resulting in a large heat loss, and the actual heating efficiency is very low. That is, since the heat discharged to the outside of the room is generally discharged as high heat, the heating rate of the fuel is lower than the combustion rate.

In the conventional briquette burning furnace, since the heat to be burned is concentrated to the discharge port side, the degree of heat dissipation differs from that of the opposite side of the discharge port during heating, and the surroundings including the discharge port of the main body, And thus the life of the briquette burner is shortened.

Therefore, if the combustion waste heat can be recovered and reused, it is obvious that the heat efficiency of the recovered amount is increased and the heating capacity of the hearth is improved.

However, as disclosed in Korean Patent Registration No. 10-0702855 entitled " Forced Convection Type Heater Stove, " a heat dissipating tube separate from the stove is provided, and then combustion gas discharged from the stove is introduced into the heat dissipating tube, There has been proposed to discharge residual combustion waste heat to the outside while passing through a large number of diaphragms installed in the inside. However, in this case, the size of the body of the heat radiating cylinder communicated therewith is larger than the size of the body of the hearth, A plurality of diaphragms installed in the heat-dissipating tube is resistant to the flow of the combustion gas, which makes it difficult to smoothly discharge the heat.

In order to solve the above difficulties, a heating gas stove having a main raw material of liquefied petroleum gas (LPG) or liquefied natural gas (LNG) such as a gas stove for a heating device of Korea Registered Utility Model No. 20-0203810 was developed.

1, a plurality of heat dissipation plates 11 are provided in front of the gas heaters 10 to radiate heat, and a heat dissipation plate 11 is provided in front of the heat dissipation plates 11, And a reflection plate 13 is installed on the slope of the heat dissipation plate 11 to reflect heat.

Accordingly, gas is supplied to the minute holes of the heat dissipating plate 11 provided on the front surface of the gas heater 10, and flame is generated in an ignition device (not shown) provided close to the front surface of the heat dissipating plate 11, And is ignited by the gas discharged from the plate 11. At this time, the heat radiated by the ignition of the heat dissipating plate 11 radiates heat at a wider angle toward the front surface by the reflection plate 13, thereby heating.

However, since the heating gas stove 10 is configured such that the heat emitted through the heat dissipating plate 11 is diverged only toward the front side, it takes a lot of time to heat the entire indoor space in a certain space, .

That is, the heating gas stove 10 is weak in heat and consumes a large amount of energy, which is inefficient.

The lower cylinder 120 includes an air outlet hole 121 for communicating with the air inlet hole 112 and for discharging outside air, an air adjusting hole 121 for controlling the amount of air sent to the air outlet hole 121, And a residue processing unit 123 for receiving residues generated after the combustion of the fuel 110a.

It is apparent that the configuration and the shape of the lower cylinder 120 can be variously embodied.

3, in order to discharge the combustion gas generated by the combustion of the fuel 110a into the body 110 through the lower cylinder 120, A discharge port 130 is formed on one side of the upper portion of the main body 100.

A discharge port 131 may be installed at a connection portion between the discharge port 130 and the communication assembly 200. The discharge port 131 is connected to the discharge port 130 through a communication assembly 200, It is obvious.

The discharge fan 131 is a part for forcibly sucking and discharging the combustion gas generated from the main body 100 to the outside for preventing leakage of the combustion gas.

That is, it is preferable that the discharge port (131) is provided in the discharge port (130) to prevent the discharge speed of the combustion gas from being lowered to induce smooth discharge.

A communication assembly 200 for exhausting a combustion gas outdoors is provided at an end of the discharge port 130. The communication assembly 200 includes a spiral communication passage 210, a double communication passage 220, .

The heat of the combustion gas generated in burning the fuel 110a such as briquettes is concentrated on the upper side of the main body 100 to dissipate heat and the rest is emitted from the side of the main body to heat the room, Most of the heat burned by the operation of the discharge fan 131 of the bar is discharged to the outside through the discharge port 130 and the communication assembly 200.

Here, the boiler apparatus having a waste heat recycling structure according to the present invention includes: a spiral communication pipe 210 for primarily utilizing waste heat of the main body 100 discharged to the discharge fan 131; A secondary communication line 220 connected to the helical communication line 210 for secondary utilization of the waste heat primaryly utilized; And a communication assembly (200) including an exhaust communication pipe (230) for ultimately discharging the waste heat that is secondarily utilized to recycle the waste heat.

First, the spiral communication pipe 210 is used for recycling the exhaust heat of the hot air and the combustion gas generated from the main body 100, that is, the waste heat, one end of which is connected to the discharge port 130, And a second end communicating with the second communication unit 220.
