In a combustion unit, a fuel collision member is disposed between a fuel injection valve and a combustion chamber. The fuel collision member is positioned so that, a part of fuel injected from said fuel injection valve is introduced into the combustion chamber while colliding with the fuel collision member, and the other part of fuel is directly introduced into the combustion chamber without colliding with the fuel collision member. Thus, fuel introduced into the combustion chamber is atomized while being introduced into the combustion chamber in a wide range.

A portable miniature incinerator is described allowing easy disposal of household garbage for a single-family house or a small apartment building. The housing of the incinerator is mounted on a wheeled hand-truck assembly and contains an incineration block and a filtration block. The incineration block in turn comprises a furnace chamber equipped with an electric heater. The heater is adapted to bring the temperature of the air and therefore the temperature of the garbage up to the point of spontaneous combustion. During the process of heating up the garbage, it becomes dry as the fans of the device remove all water evaporation. Once ignited, the garbage is incinerated in the furnace chamber while all exhaust gases are directed to the filtration unit. The filtration unit has a first stage of filtration comprising a wire mesh separator submerged in water. Exhaust gases pass through the mesh separator and through the water so that the pollutants and exhaust particles are separated from the exhaust gases. Following that first filtration stage, the exhaust gases are sent toward the second cleaning stage, this stage being a fabric-filled gas filter, for complete separation of all impurities. The gases are then directed back towards the furnace chamber to re-circulate the flow of hot gases and save energy. That process continues until the incineration is complete.

A waste incineration machine capable of rendering a waste gas occurring during the combustion of waste smokeless and odorless. A heat insulating wall to which a first far infrared ray radiator is fixed is provided so as to surround a combustion furnace and a combustion chamber, and a heat exchanger so as to surround the heat insulating wall. An inner flue is formed between the heat insulating wall and combustion furnace, and an outer flue serving as a waste gas convection chamber between the heat insulating wall and heat exchanger. An upper part of a communication portion between the inner and outer flues is covered with a heat insulating member constituting a second far infrared ray radiator so as to subject the waste gas to secondary heating using far infrared rays, and thereby to render the waste gas smokeless and odorless. Preferably, the heat insulating wall is formed into a substantially cylindrical shape, and the heat exchanger into a rectangular box-shape open at the top and the bottom, whereby the volume of the outer flue is increased to thereby lengthen the time for circulating the waste gas by convection.
