ABSTRACT:
An aircooled smokestack. The smokestack has passages within it for air or her cooling fluid. The fluid circulates through the smokestack, cooling off the internal and external surfaces. The cooling fluid is then aspirated into the stack gases near the top of the stack, thereby film cooling the upper portion of the interior of the stack. Cooling air is also aspirated into the flowing gases at the top of the stack, thereby cooling the gases as they leave the stack.
