WASTE INCINERATOR

PURPOSE:To obtain a waste incinerator, which enables to incinerate waste in smokeless and odorless state by a structure wherein the relationship between the height and diameter of the space in the incinerator is specified. CONSTITUTION:An exhaust port 6 is formed at the central part of the top wall of the combustion chamber 2 and at the central part of the bottom wall of the dust collecting chamber 4 of an incinerator 1. In addition, a waste charging port 7 is openably provided on the side wall of the combustion chamber 2. Further, a burner 8 is arranged tangentially directing donwards. During the incineration of waste, the gas in the incinerator is induced to be sucked out by means of the negative pressure produced in an exhaust tube 9 by the action of an ejector fan 12. When the height H and the diameter D of the space 1' in the incinerator satisfies the relation of H>=1.2D, burner flames form primary vortices A along the inner wall of the combustion chamber 2 and descend so as to burn waste. Only the specifically lighter high temperature heated gas form a secondary vortex denoted by B and swirlingly ascends at high speed and is discharged outside the incinerator through the exhaust tube 9.
