Abstract
A single unit, shell and tube fume incinerator utilizes a vacuum baffle (34) structure proximate a combustion zone (24) to control the flow of combustion exhaust gas. The vacuum baffle (34) is located slightly above the hot ends of a plurality of heat exchange tubes (20) to deflect the hot exhaust gases from the combustion zone (24) away from the ends of the tubes (20), and back to the outside of the tubes (20), thereby controlling the 'time at temperature' for contaminants in the impure gas feed. A vacuum effect is created just below the baffle (34) to draw cleansed exhaust below the baffle (34) back up into the combustion zone (24) to prevent the escape of impure gas.
