Abstract: PURPOSE:To shorten and stabilize the burning flame and prevent the attachment of soot by forming a plurality of small holes for secondary air in the circumference of an inner cylinder and placing a flow straightening cylinder at the position where it is opposite to part of the small holes for secondary air. CONSTITUTION:When ignition electrodes 10 are ignited, the mixture of fuel sprayed from a nozzle 9 and the primary air that is supplied through a revolving member 3 burns and it burns completely by secondary air that is supplied from the small holes 8 of an inner cylinder 2. However, the area where the density of particles of the fuel oil is high is developed in the range from the tipe end section of a flow straightening cylinder 13 to the section where the small holes lie so that the secondary air alone from the small holes 8 that are formed in the inner cylinder 2 gives rise to a shortage of air and incomplete combustion and local attachment of soot occur. Accordingly besides the secondary air from the small holes, air that passes a small hole 16 and a gap 17 between the inner cylinder 2 and the flow straightening cylinder 13 is supplied to bring about complete combustion. The flow straightening cylinder 13 is provided with small holes 15 and since secondary air is supplied through the small hole 15, flame is stable, and the size of fuel particles becomes smaller further by heating, and the combustion becomes stable and the incomplete combustion and attachment of soot are prevented.
