1 to 6, the combustion apparatus using a pressure difference according to the present invention according to the present invention fuel 10 is injected into the inside, and is sealed by the partition wall 20, the fuel inlet 30 and the air inlet The fire chamber 50 provided in the front and the holding chamber 60 in which the flue 90 for discharging the smoke of the fuel 10 burned in the fire chamber 50 to the atmosphere are provided.
In the present invention, the transverse direction means a transverse direction with respect to the front surface of the fuel injection hole 30 formed on the basis of FIG. 1.

Fuel 10 applied to the present invention is applied to wood, rice husk, sawdust, waste vinyl, milk powder, fallen leaves, hay.

The present invention utilizes the convection phenomenon caused by the pressure difference and pressure difference generated during combustion in the firebox 50.

The firebox 50 for this purpose forms a predetermined space therein through the left side, the right side partitions 21 and 22, and the upper and lower side partitions 23 and 24, the front and rear partitions 25 and 26.

3A and 3B, an auxiliary flue 92 connected to the flue 90 is formed as an upper partition 23 of the fire chamber 50, and an opening 94 is installed in the auxiliary flue 92. When the fuel 10 inside the firebox 50 closes the opening and closing hole 94 when it is burned, convection occurs inside the firebox 50 to be described later, and is discharged to the flue 90 through the staying chamber 60. When the fuel 10 is injected into the firebox 50, the opening and closing hole 94 is opened to prevent the smoke and the gas inside the firebox 50 from being discharged to the fuel inlet 30.

In addition, an inclined slit plate 70 is provided inside the fire chamber 50. As in one example, the inclined slit plate 70 is located between the left and right side partition walls 21 and 22 and extends in the rear partition wall 26 direction.

The fuel 10 is accommodated and seated in the inclined slit plate 70 and supports them.

The fuel inlet 30 and the air inlet 40 are formed in the front partition 25 of the firebox 50 on the basis of the inclined slit plate 70, and the fuel inlet 30 is open and close. The rotary door type structure, the air inlet 40 is a structure that can adjust the inflow amount of air.

Again, the slanted slit plate 70 is a flat plate 76 between the left and right slit plates 72 and 74 and the left and right slit plates 72 and 74 coupled with the left and right side partition walls 21 and 22. It is composed of

Perforated grooves 78a and 78b are formed in the left and right slit plates 72 and 74 and the flat plate 76, and the guide tip 79 is formed at one side of the perforated groove 78b formed in the flat plate 76. ) Is integrally formed.

The perforated grooves 78a of the left and right slit plates 72 and 74 serve to introduce air introduced through the air inlet 40 into the firebox 50, and the perforated grooves formed in the flat plate 76. 78b serves to discharge the gas and smoke generated after the combustion to the staying chamber 60.

The guide tip 79 formed in the flat plate 76 is for inducing the discharge of the gas, smoke discharged to the perforated groove 78b smoothly, to prevent the back flow of the gas, smoke.

Gas and smoke discharged after combustion should be guided without loss to the retention chamber 60, the communication tube 80 is coupled to the lower side of the flat plate 76 for this purpose.

That is, the gas and smoke discharged through the perforated grooves 78b of the flat plate 76 are guided to the residence chamber 60 through the communication tube 80, and the fire chamber 50 and the residence chamber 60 are sealed. It communicates with the staying room 60 only through the communication pipe 80.

In addition, referring to Figure 5, the communication tube 80 is coupled by a coupling means to be detachable to the lower portion of the flat plate 76, preferably the coupling projection (77a) formed on both sides of the lower end of the flat plate 76 ( 77 protrudes downward, and fastening protrusions 82 are formed on both sides of the upper end of the communication tube 80 so as to be fitted into the coupling grooves 77a.

As shown in FIGS. 1 and 5, the inside of the communication tube 80 is located on the front side of the communication tube 80 and the upper side of the air inlet 40 coaxial with the longitudinal direction of the communication tube 80. Each viewing window 42, 84 may be further formed to be visible from the outside.

As another embodiment of the inclined slit plate 70 and the communication tube 80, as shown in Figure 6 between the left and right slit plates 72, 74 provided on the left side, right side partition wall 21, 22 The gas and smoke are spaced apart by a predetermined distance so as to flow into the interior of the communication tube 80, the communication tube guide frame (77b) is formed so that the communication tube 80 is inserted into the bottom of the left, right slit plate (72) (74). May be

The process of completely burning the fuel 10 through the structure inside the fire chamber 50 having the above structure will be described in more detail.

As shown in FIG. 7, the fuel 10 is stored in the left and right slit plates 72 and 74 through the fuel inlet 30 and then ignited, and the air inlet 40 is opened.

The air introduced through the air inlet 40 combusts the fuel 10, and the combusted air rises due to the pressure difference, and causes convection to fall back to the lower side under the low pressure. At this time, the temperature inside the firebox 50 gradually forms a thermal equilibrium at a predetermined boundary line.

As shown in FIG. 8, the upper side of the firebox 50 is maintained at a high pressure and a high temperature, and the burned air generates vortices at the upper left and right slit plates 72 and 74.

These vortices are repeatedly circulated in the upper left and right slit plates 72 and 74, further increasing the temperature inside the firebox 50.

At this time, since the lower side of the flat plate 76 at the center of the left and right slit plates 72 and 74 is relatively low pressure, gas and smoke are discharged to the communication pipe 80 coupled to the lower side of the flat plate 76.

As shown in FIG. 9, when the inflow of air is reduced in a high temperature state, the fuel 10 gradually burns due to the oxygen trapped and is raised to 1000 ° C. or more while maintaining a high temperature state.

At this time, the gas generated from the fuel 10 due to such a high temperature is re-burned and converted into colorless smoke to achieve complete combustion, and the fuel 10 is burned more slowly in the completely burned state, and the calorific value is maximized. .

By maintaining this state, the fuel 10 can be completely burned for a long time, and the ash of the fuel 10 is almost reburned and minimized.

Again, as shown in FIGS. 3A and 3B, the gas and smoke discharged after burning through FIGS. 7 to 9 are discharged to the staying chamber 60 through the communication tube 80, and the staying chamber 60 is a gas. In addition, the smoke is to stay for a certain time and then discharged to the outside through the year (90).

In particular, the staying chamber 60 has a structure that wraps the firebox 50, the foreign matter dropping plate 62 is installed in the horizontal direction inclined downward as the rear partition 26.

The foreign substance dropping plate 62 through the communication pipe 80, the ash contained in the gas, smoke, and the like to rise to the first discharged to the final discharge to the flue (90) to make foreign substances, ash, etc. It is prevented from accumulating inside the seal 60.

The foreign matter, ash, etc. filtered through the foreign substance dropping plate 62 is formed in the lower portion of the air inlet 40, and the foreign matter dropping space 100 spaced apart from the partition wall 24 is formed, and the foreign matter dropping space 100. The foreign material cleaning opening 110 is installed to be inserted and taken out to accommodate the foreign matter falling.

As described above, the outside of the staying chamber 60 is controlled to prevent the release of heat together with the gas and the smoke by controlling the discharge of the gas and the smoke inside the staying chamber 60 in which the foreign matter, ash, etc. are filtered by the foreign matter dropping plate 62. At one end of the flue 90 protruding into the opening and closing membrane 96 is formed to be rotatable.

The foreign material dropping plate 62 may be formed in plurality again as shown in FIGS. 4A and 4B, or may be formed on one surface of the staying chamber 60 facing the rear partition 26 of the fire chamber 50. The rear partition 26 of the fire chamber 50 and the rear partition 26 of the fire chamber 50 may be formed at different heights on one surface of the staying chamber 60 facing each other.
