Description

Gas recirculation smokeless furnace {GAS RECIRCULATION STOVE}

The present invention relates to a gas recirculation furnace, and more particularly, to a gas recirculation furnace for indoor heating.

Generally, a hearth means a device for heating by using heat of combustion generated when a fuel is burned, and it can be used in a room such as a home of a house, an office, a vinyl house of a farmhouse, and outdoor such as a construction site.

These stoves have been reduced in use due to the development of a variety of heating means using various energy sources such as electric heaters, but they are still preferred in areas where fuel is readily available, such as suburban houses and buildings.

Especially, recently, the cost of fossil fuel has been increased so that the heating cost has increased. However, there is a tendency to increase the demand of the stove using solid fuels having a relatively low cost and a relatively good firepower . In rural areas, heating of plastic houses is solved mainly by using solid fuel stoves. In gas stations, factories and construction sites, gas stoves and oil stoves are replaced by solid fuel stoves.

In addition, among the solid fuels, wood pellets are eco-friendly fuels made by using wood byproducts. In recent years, wood pellets have emerged as a fuel source capable of replacing fossil fuels, and fireplaces using wood pellets as fuel have been continuously developed .

Generally, a hearth includes fuel supply means for supplying fuel, combustion chamber for combustion of fuel, and communication for discharging combustion gas. Fuel is supplied to the combustion chamber through the fuel supply means, and the room is heated by the combustion heat generated when the supplied fuel is ignited and burned, and the combustion gas generated at the time of combustion is discharged to the outside through the communication.

However, in this case, it is necessary to extend the communication from the hearth and install it on the window or the like so as to pass through the outdoors, which is very cumbersome, and there is a disadvantage that the combustion gas is leaked from the joint of the communication and the room air is contaminated.

Further, since the high-temperature combustion gas is discharged immediately after the combustion, the combustion heat is not sufficiently utilized for heating, which is wasted and the thermal efficiency is low.

In addition, there is a disadvantage that the room becomes very dry when the room is heated.

In addition, the combustion heat is directly transmitted to the surface of the hearth during combustion, partially rising to a very high temperature, and there is a disadvantage that a safety accident such as an image is caused when a person touches such a portion.

In addition, since the main material of the hearth is steel metal, the temperature of the hearth is rapidly lowered after the end of the burning, so that the heating can not be maintained for a long time.

Generally, the heated air is moved to a higher position due to the lighter air than the air specific gravity due to the operation of the stove, and the relatively cool air stays in the lower part, causing an upper and lower temperature deviation. However, a person is located in the lower part of the room, and the heated air in the upper part may stagnate and the heating efficiency may be lower than the heat amount used. Therefore, it is possible to install a super-fan for rapid up-and-down stirring of the air, but it requires additional installation cost of the apparatus, causes maintenance cost, and causes noise, and can not be used even in a place where power is not supplied .

In addition, the heat of combustion emitted from the hearth can not be spread widely, and only the near area where the hearth and the air directly contact with each other is heated, so that the heating efficiency is lowered and it is difficult to heat the room evenly.

Further, there is a disadvantage that the fuel is not sufficiently contacted with the air and the fuel is incompletely combusted and the combustion efficiency is lowered.

A part of the fuel may accumulate on the bottom of the combustion chamber 100 during the transportation of the fuel or adhere to the surface of the combustion chamber 100 and may not be normally transported. The protrusion 330 prevents the fuel from being accumulated in the combustion chamber 100 The fuel can be scratched and reliably transported by the protrusion 330. [

The operation of the gas recirculation stove according to an embodiment of the present invention is as follows.

The solid fuel is injected into the combustion chamber 100 through the fuel supply pipe 420, and the solid fuel is accumulated and accumulated in the combustion chamber 100. The injected solid fuel is ignited, and the solid fuel is burned to generate combustion gas. By the operation of the blowing fan 700, the combustion gas is forcibly transferred to the gas processing unit 200 side. At this time, the combustion gas passes between the induction plates 130 in the combustion chamber 100 and is transferred to the gas processing unit 200. Since the gas flow path is extended, the combustion gas stays in the combustion chamber 100 for a long time, This is possible.

The combustion gas fed to the gas processing unit 200 flows into the first cyclone unit 210 through the intake pipe 232. The combustion gas passing through the body 230 of the first cyclone part 210 is conveyed through the exhaust pipe 233 and passes through the mixing pipe 240. At this time, the combustion gas is mixed with the heating water in the heating water tank 250 through the through hole 241 of the mixing pipe 240, and contaminants such as ashes mixed in the combustion gas are collected in the heating water. The purified combustion gas is delivered to the second cyclone part 220 through the intake pipe 232 and discharged to the exhaust pipe 233 through the body 230 of the second cyclone part 220.

At this time, the combustion gas passes through the first cyclone part 210 and the second cyclone part 220 and flows into the spiral along the inner surface of the body 230, and contaminants such as ashes in the combustion gas, Collected by the collecting part 231 under the body 230, and can be discharged by an operator if necessary.

The purge gas discharged from the second cyclone unit 220 flows into the combustion chamber 100 through the insertion tube 260 and the combustion gas generated in the combustion chamber 100 is transferred to the gas processing unit 200 for recirculation. At this time, the length of the flow path of the combustion gas is extended by the guide plate 130, the combustion gas passes through the gas processing unit 200, heats the heating water, and the treated purifying gas flows into the combustion chamber 100 again . Accordingly, since the heat loss of the combustion gas can be minimized, it can be used for heating, and the thermal efficiency is extremely high.

The fuel is transferred by the fuel transfer unit 300, which is burned while being transferred along the rotating rotary shaft 310, and the burned material is discharged through the re-discharge unit 120. At this time, the fuel is transported while being mixed by the mixing ring 320, and is transported while being repeatedly advanced and retreated, not being continuously transported in one direction. That is, in the case of a common screw, the fuel is transported only in one direction along the screw, but in the case of the present invention, the fuel is transported while mixing forward and backward repeatedly. Therefore, the fuel can be burned as close to full combustion as possible, since the fuel does not clump and air is uniformly supplied to the entire fuel and can be burned with sufficient time.

The heating water of the heating water tank 250, the humidifying unit 610, the heating unit 600, water in the water tank, and the like are heated by the combustion heat during the combustion. The heating water of the heating water tank 250 is connected to a boiler or the like by a valve 251 and can be used for heating or the like. Water vapor generated in the humidifier 610 is discharged through the humidifying hole 611, And can be used for various purposes such as placing a kettle or the like in a heating unit 600 at a high temperature or heating a food.

Further, the water in the water tank formed between the outer wall 140 and the combustion chamber 100 is heated, whereby the induction pipe 500 can be heated. The air in the lower portion of the induction pipe 500 may flow into the induction pipe 500 and may be lifted along the induction pipe 500 and then discharged to the upper portion of the induction pipe 500. [ That is, the cold air in the lower part of the room can be quickly transferred to the upper part of the room by the induction pipe 500, so that the air can be actively stirred at the upper and lower parts of the room,

In addition, since the water tank and the heating water tank 250 formed by the outer wall 140 surround the combustion chamber 100, the high-temperature combustion heat can be discharged to the outside through the water in the water tank and the heating water in the heating water tank 250. Therefore, the occurrence of safety accidents such as burns can be minimized by minimizing the direct exposure of high-temperature combustion heat and lowering the temperature of the outer surface of the hearth to which the user directly touches by water. In addition, even after the end of combustion of the stove, the heating of the water tank, the heating water tank 250, and the humidification unit 610 can be continuously performed for a while.

According to the stove of the related art, it is very troublesome to extend the communication from the hearth and to install it on the window or the like so as to pass through the outside of the room, and there is a disadvantage that the indoor air is contaminated due to the outflow of the combustion gas at the joint of the communication.

Further, since the high-temperature combustion gas is directly discharged through the communication pipe, the combustion heat is not sufficiently utilized for heating and is wasted, resulting in low thermal efficiency.

In addition, there is a disadvantage that the room becomes very dry when the room is heated.

Further, the surface of the hearth rises to a very high temperature at the time of combustion, and there is a disadvantage that it causes a safety accident such as an image when a person touches such a portion.

In addition, since the main material of the hearth is steel metal, the temperature of the hearth is rapidly lowered after the end of the burning, so that the heating can not be maintained for a long time.

Generally, the heated air is moved to a higher position due to the lighter air than the air specific gravity due to the operation of the stove, and the relatively cool air stays in the lower part, causing an upper and lower temperature deviation. However, a person is located in the lower part of the room, and the heated air in the upper part may stagnate and the heating efficiency may be lower than the heat amount used. Therefore, it is possible to install a super-fan for rapid up-and-down stirring of the air, but it requires additional installation cost of the apparatus, causes maintenance cost, and causes noise, and can not be used even in a place where power is not supplied .

In addition, the heat of combustion emitted from the hearth can not be spread widely, and only the near area where the hearth and the air directly contact with each other is heated, so that the heating efficiency is lowered and it is difficult to heat the room evenly.

Further, there is a disadvantage that the fuel is not sufficiently contacted with the air and the fuel is incompletely combusted and the combustion efficiency is lowered.

However, according to the present invention, since the combustion gas can be reused without being discharged, the thermal efficiency and the heating efficiency can be maximized, no communication is required, and there is no inconvenience of the communication installation and indoor air pollution can be prevented. In addition, it is possible to humidify the room, reduce the heating temperature variation, heat the room evenly, and reduce the surface temperature of the hearth, thereby minimizing the occurrence of safety accidents. In addition, there is an effect that the combustion efficiency can be improved by uniformly mixing the fuel and making the air supply smooth.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. Various modifications and variations are possible within the scope of the appended claims.
