And, next to the combustion chamber 10, a flame induction tank 13, which is set up substantially to the height of the combustion chamber, is installed, and penetrates out of the housing 17 from the center of the flame induction tank through the outer side of the upper part. The flue 12 is installed to protrude while being installed, the lower end of the flue is formed at a position lower than the gas duct 14, the upper side and the flame induction tank (the other side of the combustion chamber 10) ( 13, the upper part of the side is connected to each other by the gas duct 14 as described above to face the flue 12, the second ash tray having a center portion is concave at the lower end of the flame induction tank 13 (21) is installed, and the second ash tray is lowered from the bottom surface of the ash tray 21a in a state where the ash receiver 21a receiving the ash is gently curved downward as shown in FIG. The lower part of the support base 21b is long It is connected to the handle 21c.

In addition, the upper center of the combustion chamber 10 and one side of the flue are connected to each other through the combustion gas exhaust promotion pipe 15 bent by the letter A and penetrate each other, and the combustion gas exhaust promotion pipe ( The hot water heat exchanger tube 16, which is formed in the shape of a chimney, is placed on the center thereof, and one end of the hot water heat exchanger tube that protrudes outward from the housing 17 is provided with a cold water supply line (not shown). ) And the other end is connected to the hot water supply line (not shown).

Is provided, and the lower side of the other side is attached with the combustion chamber 10 and the blower 30 which follow.

The operating state of the coal briquette boiler according to the present invention configured as described above will be described in detail.

Ignition of the coal briquettes, such as coke, injected through the coal briquette inlet 18 of the combustion chamber 10 is set on the first ash tray 20 in the combustion chamber 10 by igniting an ignition flasher or an ignition coal, and then burning the fire. As it rises, the coal briquettes are added little by little to ignite. The coal briquette inlet 18 prevents backfire and prevents personal injury.

Next, after confirming the ignition of the coal briquettes, the blower 30 is operated while injecting an appropriate amount into the combustion chamber 10 to accelerate the combustion of the coal briquettes. After the combustion, the ash accumulated in the first ash tray 20 at the lower end of the combustion chamber is removed while checking from time to time through the material check opening 19.

When the coal briquettes are burned in the combustion chamber 10, high heat is generated, and thus, the inner wall of the combustion chamber is made of a refractory brick 11. But the flame and dust is introduced through the gas duct 14 to the flame induction tank 13, which is built on the principle of the dust collector.

In this case, since the flame and dust hit the flue 12 in the flame induction tank 13 facing the gas duct, the flame and the dust are induced downward and rise upward again, especially when the flame is directly introduced into the flame induction tank. By being much less affected by high heat it is possible to improve the safety of the device, dust can also be removed from time to time because it is safely stacked in the second ash tray 21 of the lower portion while moving in the same path as the flame.

In addition, the smoke generated in the combustion chamber 10 is discharged to the outside through the flue 12 installed in the flame induction tank 13 through the combustion gas exhaust promotion tube 15 of the upper combustion chamber. That is, in the combustion gas exhaust promotion tube 15 and the flame induction tank 13, the combustion gas (combustion disturbance) generated during the combustion in the combustion chamber 10 does not stay in the combustion chamber 10, but the flame induction tank 13 It moves smoothly toward the heat exchange, and the gas moved to the flame induction tank 13 passes the gas through the flue 12 in a state in which the gas flow vortexes downwards and removes dust generated in the combustion process. Let it squirt In the coal briquette boiler of the present invention, it is possible to stabilize combustion efficiency by adopting a method of indirectly discharging the combustion gas discharge, rather than a direct discharge method, thereby optimizing the combustion chamber combustion conditions to prevent heat loss.

Thus, the combustion chamber and the flame induction tank 13 are heated by the high heat of coal briquettes combusted in the combustion chamber 10, and the heating medium filled in the housing in which the combustion chamber and the flame induction tank are immersed by this heating, for example, water The water is heated and used as the heating water flowing to the heating line through the heating outlet 28 and the heating return port 29, and furthermore, the water is introduced into the water pipe by the water pipe 25 installed in the combustion chamber 10. Since it passes continuously, the water in the housing is heated more efficiently, and the cold water in the heat exchanger tube 16 for hot water introduced through the cold water supply line with the water filled in the combustion chamber 10 and the housing is heated to make hot water. Make it hot water through the supply line.
