COMBUSTION APPARATUS FOR SOLID FUELS AND MULTIPURPOSE HEATING APPARATUS COMPRISING SAID COMBUSTION APPARATUS}

The present invention relates to a combustion apparatus for a solid fuel and a multipurpose heating apparatus including the same, and more particularly, to a combustion apparatus and a multipurpose heating apparatus capable of efficient combustion and hot water supply.

In general, in order to heat a large indoor space such as a plastic house or a factory, the consumption of oil and gas required is not small and expensive maintenance costs are required. In addition, fuel costs due to the rise in oil prices are overlapped, so farmers or factories reduce production costs, and public institutions use relatively low fuel costs such as briquettes, coal, and lignite. have.

The conventional heating device for solid fuel is composed of a combustion device which burns solid fuel with air provided from the lower part, which is provided with a rostol in which the solid fuel is stored, and a combustion air exhaust part through which the burned air is exhausted. It transfers heat, raising the temperature of the room.

Solid fuel, such as coal, is positioned on the rostol and combustion occurs. At this time, air necessary for combustion is supplied from the lower portion due to the hole formed in the rostol. In addition, the hole of the rostol is also used as an opening through which ash produced after the combustion of the solid fuel is completed. Then, the air combusted by the combustion device is exhausted through the communication located above the heating mechanism.

The combustion of solid fuel takes place on its surface. In addition, when the volume of one solid fuel and the total volume of the plurality of small solid fuels are the same, the surface area of the plurality of small solid fuels is larger than that of one solid fuel having the same volume. As a result, a plurality of small solid fuels have better combustion efficiency than one large solid fuel combustion and complete combustion can occur more smoothly. However, in the conventional combustion apparatus of the heating device for solid fuel, a large solid fuel is directly stored and supported in the rostol. Therefore, the combustion device that burns solid fuel having a small surface area relative to its volume, that is, a large solid fuel, has a problem of low combustion efficiency, and since the solid fuel that is not completely burned accumulates in the rostol, air supply is not desired. There was a problem that the combustion is stopped.

In addition, due to the structure of a conventional combustion device, when the combustion of the combustion device is stopped in order to burn again, the solid fuel directly supported by the rostol has to be removed and re-ignited to refill the solid fuel.

In addition, the ash accumulated in the rostol, the air holes formed in the rostol are often closed, it was very troublesome to shut down the heating mechanism and clean the rostol.

In addition, although the combustion gas generated in the combustion device has a high temperature thermal energy, there is a problem that a large amount of thermal energy is directly discharged to the exhaust portion and deteriorated.

In addition, solid fuels have been cumbersome to inject solid fuels frequently, even though they are more difficult to store and supply than liquid and gaseous fuels.

Therefore, the inventor has come to invent a combustion apparatus and heating apparatus for a solid fuel having a novel structure that can solve the above problems.

It is an object of the present invention to eliminate burnout phenomena due to solid fuel that is not completely burned.

Another object of the present invention is to increase the surface area of solid fuels having a small surface area relative to the volume, thereby increasing combustion efficiency.

Still another object of the present invention is to provide a multipurpose heating apparatus capable of supplying hot water, warm air, etc. in addition to directly raising the indoor temperature.

Yet another object of the present invention is to reduce the amount of waste heat of the combustion gases to recycle thermal energy.

Another object of the present invention is to easily reburn solid fuel when the combustion of the combustion device is stopped.

Still another object of the present invention is to provide a solid fuel conveniently by solving the trouble of fuel supply.

Another object of the present invention is to solve the phenomenon that the air hole of the rostol is closed by ash.

Preferably, around the at least one exhaust pipe, a warm air heating unit for heat exchange with the exhaust pipe may be located. As a result, the amount of waste heat of the combustion gas can be reduced to recycle thermal energy.

Preferably, a blower for introducing external air into the warm air heating unit may be installed above the warm air heating unit to increase the heat exchange efficiency between the exhaust pipe and the warm air heating unit.

Preferably, a warm air outlet for discharging the warm air heat exchanged with the exhaust pipe may be formed below the outer side wall of the warm air heater. For this reason, the heating device for solid fuel can provide warm air.

Also preferably, a lid for sealing the solid fuel reservoir is installed at an upper end of the solid fuel reservoir, a handle is formed on an upper surface of the lid, and the side of the lid may be surrounded by a packing member. By using the vacuum-sealed cover, it is possible to prevent the flame of the combustion device from developing to the solid fuel reservoir, so that the solid fuel can be continuously stored and burned continuously.

According to the present invention, there is an effect of eliminating the combustion interruption phenomenon due to solid fuel that is not completely burned, and at the same time, it is possible to increase the combustion efficiency by increasing the surface area of the solid fuel having a small surface area relative to the volume, When the combustion of the combustion device is stopped, there is an effect of easily reburning the solid fuel.

In addition, it is possible to supply solid fuel conveniently, and there is an effect of solving the phenomenon of closing the air hole of the rostol with ash.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Front and sectional views of the combustion apparatus 100 and the multipurpose heating apparatus 1 for solid fuel of the present invention are shown in FIGS. 1 and 2. Solid fuel support water pipe 130 of the combustion device 100 is shown in more detail in the cross-sectional view of FIG.

As shown in FIG. 1, the multipurpose heating apparatus 1 for a solid fuel of the present invention includes a solid fuel combustion device 100, a solid fuel storage container 300 arranged above the combustion device 100, and And a hot air blower unit 200 arranged around the solid fuel reservoir 300, and a communication 400 disposed at an upper portion of the hot air blower unit 200 to discharge combustion gas.

Furthermore, it is preferable to specify the heating device for solid fuel, in order to facilitate the maintenance of the heating device for solid fuel of the present invention, and to facilitate the removal of ash formed by the complete combustion of the solid fuel (C). The parts are provided with a sweeping tool 500.

As shown in FIG. 1, according to a preferred embodiment of the present invention, the combustion device 100 includes a housing 110, a rostol 120 arranged to cross the inside of the housing 110, and the The interior of the housing 110 is composed of a plurality of solid fuel support water pipe 130 which is located above the rostol 120.

The housing 110 forms an outer sidewall of the combustion device 100. Since the solid fuel C is burned in the housing 110, the combustion device 100 transmits heat through the housing 110. That is, the housing 110 may serve as a so-called stove directly radiating combustion heat.

1 and 2, the solid fuel support water pipe 130 is installed on the rostol 120, and the solid fuel support water pipes 130 are reduced by the combustion of the solid fuel C. It is arranged not to pass before. In other words, this means that the spacing between the solid fuel support water pipes is smaller than the size of the solid fuel. For this reason, the solid fuel C before combustion is primarily supported by the solid fuel support water pipe 130. Also, preferably, the solid fuel support water pipe 130 may be installed in multiple stages on the rostol 120. Here, the term "multistage" refers to a manner in which a plurality of solid fuel support water pipes forming one end are arranged at different heights.

By using the solid fuel support water pipe 130, since the shots having a smaller size than the solid fuel C of the solid fuel support water pipe 130 are burned in the rostol 120 to be described below, the combustion surface area is increased. This can increase the combustion efficiency and allow the solid fuel to burn smoothly and completely. This makes it possible to considerably eliminate the combustion interruption phenomenon due to the accumulation of solid fuel that is not completely burned.

Moreover, since a substantial amount of solid fuel in the solid fuel in the combustion apparatus is supported by the solid fuel support water pipe 130, it is necessary to take out all the solid fuel in the combustion apparatus in order to stop the combustion of the combustion apparatus and reburn the solid fuel. There is no. That is, the solid fuel supported by the support water pipe is left as it is, and only the small solid fuel supported on the rostol is taken out and reburned, and the flame on the rostol is located at the top by remounting the rostol in the combustion apparatus. It is to reburn the solid fuel in the water pipe. Therefore, the combustion apparatus of the present invention can easily re-burn solid fuel without incurring much effort even if the combustion is stopped unlike the prior art.

In addition, the outer side of the housing 110, the water supply unit 131 for supplying water to the solid fuel support water pipe 130 and the hot water discharge unit for discharging hot water from the solid fuel support water pipe 130 ( 133 is installed. For this reason, the multipurpose heating apparatus 1 for solid fuel of the present invention may not only serve as a heater directly through the housing 110 but also provide hot water.

The rostol 120 secondaryly supports the solid fuel C miniaturized by combustion in the solid fuel support water pipe 130. As a result, the combustion surface area of the solid fuels is widened in the rostol 120 so that complete combustion occurs smoothly, thereby increasing combustion efficiency.

In addition, a large number of holes are formed in the rostol 120 so that air flows from the lower side during combustion and ashes are removed when the solid fuel C is burned and then ashed.

Preferably, a means for applying vibration to the rostol 120 may be provided under the rostol 120. For example, as a means for applying a vibration, a scaffold 121 which is vertically fixed to the lower part of the stole 120 and a scaffold that is pivotally connected to the vertical shaft 121 and extends outside the housing 110. 123 may be used (see FIG. 1). By stepping on the scaffolding portion 123 several times, the shaft 121 fixed to the rostol 120 may be moved up and down to apply vibration to the rostol 120.

For this reason, it is possible to prevent the ash accumulated in the rostol 120 from agglomerating, thereby preventing the air hole of the rostol 120 from being closed. Therefore, the hassle of frequently washing the rostol 120 may be eliminated due to the closing of the air hole of the rostol 120.

On top of the combustion device 100, one or more exhaust pipes 140 are installed so that the combustion gas from the combustion device 100 can be discharged to the communication 400 (see FIG. 1). The one or more exhaust pipes 140 are arranged around the solid fuel reservoir 300 to be described below. In addition, the exhaust pipe 140 may be integrally formed with the combustion device 100. In addition, the exhaust pipe 140 is preferably formed of a material having a high thermal conductivity in order to increase the heat exchange efficiency with the hot air heater 210 to be described later.

As shown in FIG. 1, according to a preferred embodiment of the present invention, the warm air heater 200 may include a warm air heater 210 positioned to surround the one or more exhaust pipes 140, and the warm air heater ( The air blower 220 is installed on the upper portion of the 210 and the warm air outlet 230 formed on the lower side of the outer side wall of the hot air heating unit 210. The hot air blower unit 200 is arranged in a shape surrounding the solid fuel storage tank 300 and the on-gas gas pipe 140 (to be described below) located on the upper portion of the combustion device 100 as a whole.

The warm air heating unit 210 is formed in a shape surrounding the one or more exhaust pipes 140 as a whole so as to exchange heat with the exhaust pipes 140 through which the hot combustion gas passes. Combustion gas does not flow into the warm air heater 210, and clean outside air and warm air flow. By providing the warm air heating unit 210 as described above, it is possible to prevent waste heat of high temperature thermal energy of the combustion gas.

The blower 220 is installed above the warm air heater 210 (see FIG. 1) to supply external air into the pipe. In addition, the blower 220 prevents the outside air, whose temperature rises due to heat transfer from the exhaust pipe 140, rises due to convection. That is, the blower 220 forcibly flows the hot air to flow in the downward direction. By placing the blower 220 in the upper portion, the heat exchange time between the exhaust pipe 140 and the warm air heater 210 may be extended, thereby improving heat exchange efficiency.

Preferably, the warm air outlet 230 is formed at the lower portion of the outer side wall of the warm air heating unit 210 (see FIG. 1) to extend the heat exchange time between the exhaust pipe 140 and the warm air heating unit 210. It is possible to improve the heat exchange efficiency.

As shown in Figure 1, according to a preferred embodiment of the present invention, the solid fuel reservoir 300 is connected to the upper portion of the combustion device (100). The solid fuel storage container 300 serves to store the solid fuel (C) before combustion. In addition, the solid fuel storage bin 300 is configured to move the stored solid fuel (C) toward the combustion device 100 by gravity when the solid fuel (C) is exhausted in the combustion device (100) below during combustion. It serves to continuously supply the solid fuel (C) to the combustion device (100). By using the solid fuel storage container 300, it is possible to eliminate the need to supply fuel frequently.

In addition, the cover 310 may be installed at an upper end of the solid fuel storage container 300 to seal the storage container 300. Preferably, the handle 320 is formed on the upper surface of the cover 310, the packing member 330 may be formed on the side of the cover 310 to seal the upper end of the storage container (300).

Thus, by sealing the reservoir 300 in a vacuum sealing manner using the packing member 330 of the cover 310, it is possible to maintain the inside of the reservoir 300 in a vacuum state, the flame in the combustion device 100 Combustion of the solid fuel C in the reservoir 300 can be prevented. For this reason, the storage container 300 can continuously supply the unburned solid fuel C, and the combustion device 100 can burn the solid fuel C continuously.
