Conventionally, a stove that uses solid coal such as coal, lignite, and mace charcoal as a fuel has a drawback in that when the amount of coal is increased, the pollution smoke is remarkable due to incomplete combustion and the heating effect is lowered.

In addition, when the fire is turned off again, the ignition work is not only cumbersome, but the burn time is too short for a single supply.

In order to solve this drawback, in order to solve this drawback, the rotating grate formed with the central fusion body of the pore snow was formed on the ordinary fixed grate formed on the base surface, and the pressure air chamber and the two side coal fired ports were formed at the periphery of the surface. A combustion cylinder installed in the tank was installed at both ends of the coal tank, and the end of the coal spiral tube wound around the outside space of the exhaust cylinder was introduced. The thick coal seam also promotes complete combustion, and the coal fired spiral spirals wound around the outer space of the exhaust chamber allow solid coals to gliding long distances in a spiral space. As follows.

The rotating grate 6 formed with the central fusion body 5 of the pores 4 is formed on the fixed stationary grate 3 formed on the bottom surface 2 of the base 1, and the pressure air is formed at the periphery of the concave surface 2. The chamber (7) and the feeder (10) and the 10 '(10') are provided with a pore (8) combustion cylinder (9), which is turned on the main wall. It is made by introducing the feed grenade spiral pipe 14, 14 'which is introduced from the ball throwing ball holes (12) (12') and spirally wound in the space outside the exhaust pipe (13).

In the drawings, reference numeral 15 denotes left and right fluctuations, 16 blisters, 17 communication tubes, 18 hot water pipes, 19 water return pipes, 20 carbon container vessels 21, air conditioners, 22 dampers, and 23 solid coals. Will.

The present invention constructed as described above covers the rotating grate (6) formed with the central fusion body (5) of the pore (4) and the ceiling on the fixed grate (3), and the base (1) concave surface (2) of the peripheral pressure air chamber ( 7) and the coal fire ports (10, 10 ') is installed in the pores (8) in the main wall of the circumferential wall (8) because the combustion cylinder (9) The hot air from the pressure air chamber (7) of the air and the combustion cylinder (9) expands deeply into the thick coal seam, which is injected from the pores (8), so as to promote complete combustion. It is effective to increase.

In addition, it is connected to the feed holes 10 and 10 'of both side walls of the combustion cylinder 9, and is connected to the two ball throwing holes 12 and 12' above the side wall of the outer heat insulating cylinder 11 to form an outer circumferential wall space of the exhaust cylinder 13. Since the spirally wound feed spiral pipes 14 and 14 'were inserted, the solid coals 23, such as coal and masset, injected into the ball throwing ball holes 12 and 12' are spirally fed into the spiral feed pipes 14 Since the coal seam in the combustion cylinder 9 is helically slid inward and the coal bed in the combustion cylinder 9 is settled down by combustion, it is supplied little by little into the combustion cylinder 9, thereby activating combustion for a relatively long time.

Therefore, in the case of home use, the fire is not exhausted even during the night, there is an advantage to maintain high heating continuously.

And since the solid coal 23 is less ash (about 1% ash in the case of lignite), the left and right fluctuations (15) is sometimes shaken from side to side.

In carrying out the present invention as shown in the accompanying drawings When the blister 16 of the cross section is installed above the combustion cylinder 9, a hot water boiler having a high thermal efficiency is formed, and if the blister 16 and the determination column 11 are omitted, a stove is formed.

When the length of the spiral pipes 14 and 14 'is designed to be short, the number of feed ports 10 and 10' of the side wall of the combustion cylinder 9 may be increased.
