An incinerator for combustible or thermally-decomposable gases includes a device which insures that gas continues to flow through the incinerator in the event of failure of the scrubber fan connected to the outlet of the incinerator. When the scrubber fan fails, a solenoid-operated valve opens, and compressed gas from a tank flows through the valve into the main conduit of the incinerator. The compressed gas enters the main conduit through an air flow amplifier installed within the main conduit. The air flow amplifier magnifies the effect of the compressed gas, and creates a region of negative pressure which assures that toxic or hazardous gases do not remain in the incinerator, but instead continue to flow toward the scrubber fan, even after the fan has failed.
In an incinerator for combustible or thermally-decomposable gas, the incinerator comprising a first pipe having open entrance and exit portions and an inlet opening disposed between the entrance and exit portions, a second pipe having first and second ends, the first end being fixed about said inlet to provide fluid communication between the pipes, the second end being substantially closed to an outside environment, ignition means disposed within the second pipe, means for conveying at least one combustible gas into the second pipe, and means for turbulently conveying a stream of a gas capable of supporting combustion into the entrance end of the first pipe, and for centrifugally swirling said turbulently flowing gas into and out of the second pipe and for discharging said turbulently flowing gas through the exit end of the first pipe, the exit end of the first pipe being connected to a conduit having means for drawing gas through the first pipe,
In an apparatus for incinerating combustible or thermally-decomposable gas, the apparatus including a first pipe member having an open inlet end and an outlet end, the first pipe member fluidly communicating with a second pipe member which has an ignition means disposed therein, and means for turbulently conveying gas from the first pipe member into the second pipe member and back to the first pipe member, and for directing said gas to the outlet end of the first pipe member, the outlet end of the first pipe member being connected to an outlet conduit having a fan disposed therein, the fan comprising means for drawing gases through the first pipe member,
An incinerator for combustible or thermally-decomposable gas, comprising a first pipe having an open end for allowing a combustion-supporting gas into the first pipe, a second pipe in fluid communication with the first pipe for admitting the combustible or thermally-decomposable gas into the first pipe, means for turbulently mixing the combustion-supporting gas with the combustible or thermally-decomposable gas, the first pipe being connected to an air flow amplifier, the air flow amplifier having an outlet end connected to a duct, the duct having a fan disposed within the duct for drawing gases out of the first pipe, the air flow amplifier being driven by a source of compressed gas, and means for directing the compressed gas into the air flow amplifier in the event of failure of the fan.
A method of removing toxic gases from an incinerator in the event of failure of a scrubber fan, the scrubber fan being provided to draw gases out of the incinerator and into an outlet duct, the method comprising the steps of:
