All chimneys have to be built with a flue lining to protect the masonry from combustion gases, of which the lining also improves the flow. FLUE: A vertical pipe or duct that provides a safe pathway for heat, smoke and other combustion byproducts away from the fireplace. Lies within the interior of the chimney.

Similarly, it is asked, how do chimneys work diagram?
Chimneys operate on the principle that hot air rises above cold air. The movement of hot gases rising from the fire creates a pressure difference between the inside of the flue and the room.

Subsequently, question is, why do chimneys have a bend? The hotter the temperature inside the flue, the more efficiently gases will be conducted up and out of the house. Bends, or offsets, in the flue can retard the steady outflow of gases. They also interfere with the flow of oxygen through the chimney to the fire.
