The present invention relates to a firewood combustion apparatus without smoke, and in detail, by reducing the amount of smoke that causes pollution by maximally burning and discharging the smoke generated during the combustion of various wood, chaff, or waste or livestock manure. In addition, it is possible to improve the thermal efficiency by making the residence path of smoke and heat as long as possible, by forming a residence chamber at the rear of the combustion chamber and providing an exhaust grill to form an exhaust flow between the combustion chamber and the residence chamber. By burning the fuel and gas generated by burning the fuel in multiple stages at the upper and lower parts of the combustion chamber and the exhaust grill side, the amount of smoke that causes pollution is significantly reduced, and the residence and path of smoke and heat are kept as long as possible. It is to maximize the efficiency of heat exchange with the filled water.

50 to 80% of the heat generated from burning firewood in a typical firewood boiler or stove is thrown out together with the smoke of the smoke, and the fire loss is excessively excessive, but the thermal efficiency is extremely low. Some methods have been developed to lengthen, bypass or downward the passages through which combustion gases and smoke are discharged to absorb the heat lost with smoke as much as possible.

As shown in Fig. 9, the bottom type flue wood boiler of Utility Model Registration No. 193809 (registered on June 14, 2000) is installed in two by separating the ignition door and the fuel replenishing door in a wood-fired boiler.

The communication unit 126 is provided in the discharge part 112 so as to absorb the heat emitted from the communication unit 126 as much as possible.

In the coal fired boiler according to the prior art as described above, by simply installing the communication inside the boiler, the heat stored in the water tank can be absorbed by the water tank as much as possible. Although it can be seen, the heat and smoke actually generated during the combustion of the fire is discharged to the outside quickly through the communication, so there was a problem that the heat exchange efficiency does not improve so much, and the combustion of the fire does not make a large amount of smoke. Of course, there was a problem that the smooth discharge of the smoke generated during combustion is not made.

The present invention has been made in order to solve the above problems, an object of the present invention is to cause the pollution by burning the exhaust smoke generated during the combustion of the fire in the stove or hot water heating boiler or hot water boiler made of wood, etc. as possible.
