What Do Smoke Stacks Do?

Whether fueled by incinerators, boilers or fireplaces, smoke stacks function on the concept of the stack effect. This concept relies on the movement of air through the pressures of buoyancy. In other words, the stack effect relies on an exhaust, or stack, which assists in the release of hot air and contaminants to the exterior of the structure.

When higher-pressure hot air is surrounded by lower-pressure cool air, the hot air rises. Because the air doesn’t move steadily on its own, the stack effect involves the use of a heat generator to expand the air. So, once the air has been heateed and increased in pressure, it's expelled out of the smoke stacks and then replaced by cooler air, causing the cycle to repeat.
