Combustion method for specific exhaust gases containing deleterious substances |
(57) A method for the combustion of specific exhaust gases such as silane-containing exhaust
gases discharged from a reaction furnace in which a combustible gas is supplied to
and burnt around the top end of a nozzle for the exhaust gases, thereby forming a
