Abstract
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.
