A plurality of dry distillation furnaces (2a), (2b) are provided for a single combustion furnace (4). When wastes (A) in the dry distillation furnace (2a) are subjected to dry distillation to produce a combustible gas and introduce the combustible gas into the combustion furnace (4) to burn, control is carried out such that a temperature (Tc) in the combustion furnace (4) becomes a first temperature. When the temperature (Tc) in the combustion furnace (4) is the first temperature, the presence of the wastes (A) in the dry distillation furnace (2b) is detected, the wastes (A) in the dry distillation furnace (2b) are ignited to subject the wastes (A) to dry distillation thereby to produce a combustible gas, and the introduction of the combustible gas into the combustion furnace (4) is started.

The present invention is intended to provide a hybrid combustion apparatus using the pyrolysis of water and combustion air, in which a combustion chamber is defined by a double wall and divided into a primary combustion chamber configured to combust waste and a secondary combustion chamber configured to combust exhaust gas, and the size (diameter) of a combustion unit through which waste is configured to be different from that of the combustion chamber in which a flame is located, so that combustion temperature is further increased by introducing air, so that heated due to proximity to a flame, as combustion air, combustible waste is combusted at an ultrahigh temperature by pyrolyzing water and combustion air by means of a high combustion temperature, and so that complete combustion is achieved by increasing the time for which a flame stays within the combustion chamber, thereby discharging clean exhaust gas.

An environmentally friendly combustion chamber for stable combustion of biomass gasification combustible gas. The combustion chamber is divided into a first stage cavity body (45) and a second stage cavity body (48) by a honeycomb-shaped heat storage body (46). A combustion pipe (41) is connected to a biomass gas inlet and a primary air distribution pipe (54), the combustion pipe (41) is connected to the first stage cavity body (45), and an ignition gun (42) and a thermocouple T1 are arranged on the first stage cavity body (45). A secondary air distribution pipe (47), opposite the honeycomb-shaped heat storage body (46), and a thermocouple T2 are arranged within the second stage cavity body (48), and the second stage cavity body (48) is connected to an outlet high temperature flue gas pipe (51). The primary air distribution pipe (54), a primary air volume adjustment valve (52), the secondary air distribution pipe (47) and a secondary air volume adjustment valve (53) are connected together to an air supply fan (49), and a controller (50) is connected to the thermocouple T1, the thermocouple T2, the primary air volume adjustment valve (52), the secondary air volume adjustment valve (53) and the air supply fan (49). The combustion chamber solves the problems of unstable combustion flames in traditional combustors, and high nitrogen oxide amounts in tail flue gas.
