    摘要： A method of burning exhaust gases containing gaseous silane in which the exhaust gases containing gaseous silane to be introduced into a combustion chamber are diluted with an inert gas so that the concentration of silane gas is reduced to less than 30% by volume and the diluted exhaust gases are fed from a nozzle to the combustion chamber and burnt through reaction with airs in the combustion chamber while the region between the head of the nozzle top end and the base portion of the burning flame is shielded with an inert gas atmosphere. An inert gas mixing pipe 17 is connected for dilution to an exhaust gas feed section 16, an enclosure pipe 21 is fitted to the outer circumference of an exhaust gas introduction pipe 13 introduced into the combustion chamber 6 to constitute a double pipe structure, and the enclosure pipe 21 is connected at the rear end thereof to an inert gas feed pipe 25 and slightly protruded at the top end thereof ahead of the top end of the exhaust gas introduction pipe.

    摘要： A combustion chamber (1; 101), is surrounded by a heater (4; 104), by means of which a constant temperature in the order of 850°C can be maintained in the chamber (1; 101). The chamber (1; 101) has arranged therein devices (17, 18, 117) which, when the arrangement is in operation, partly obstruct the passage of gas through the chamber. The waste gases to be treated are introduced into the chamber (1; 101) through an inlet (2; 102) and the treated, residual waste.gas is discharged from the chamber through an outlet (3; 103). The arrangement also includes a supply line (14,15,-16,114,1151 for supplying pre-heated reaction medium to the interior of the chamber (1; 101).

    摘要： A combustion device comprises a combustion chamber (12), means (16) for generating gaseous products of combustion in the combustion chamber, and a passage for the gases which includes an exhaust (30) which has at least one heat recovery heat exchanger (18 to 26) therein, the heat exchanger having a surface coated with a catalytic material for oxidising the gaseous products of combustion to recover heat therefrom.

    摘要： A flare stack tip assembly serves to discharge waste gas for disposal by combustion. The assembly has an upper frusto-conical tip structure (8) to which a plurality of injector devices (16) are mounted. Each of the injector devices (16) is supplied with steam which flows through a protected annular passageway (41) therein. The annular flow of steam in each device (16) induces ambient air to flow into an open inlet of the device and to mix with the surrounding steam for discharge into the waste gas passing up through the assembly prior to combustion.
