What is another word for smoke duct?
Pronunciation: [smˈə͡ʊk dˈʌkt] (IPA) 
A smoke duct is a passage designed to carry out smoke generated from fire or combustion processes. The term smoke duct can be used interchangeably with other terms such as flue, chimney, vent, or exhaust pipe. A flue pipe is a type of smoke duct that conveys exhaust gases from heating appliances like stoves, furnaces, or boilers outside the building. A chimney, on the other hand, is stacked vertical structure that creates an updraft to carry smoke out of the building. Vent and exhaust pipe also perform similar functions but are typically used in smaller applications such as kitchen or bathroom exhaust fans.
