What is Chimney?
[[Image:GRES-2.jpg|thumb|The world's tallest chimney can be found at [[Ekibastuz]], [[Kazakhstan]].]] A '''chimney''' is a structure used to ventilate hot [[flue gas]]es or [[smoke]] from a [[boiler]], [[stove]], [[furnace]] or [[fireplace]] to the outside [[Earth's atmosphere|atmosphere]]. Most chimneys are vertical, or almost vertical, to make sure that the gases flow easily, drawing air into the [[combustion]] in what is known as the [[stack effect|stack, or chimney, effect]]. The space inside a chimney is called a ''[[flue]]''. Chimneys may be found in buildings, steam locomotives and ships. In the [[United States]], the term '''smokestack''' is also used when talking about [[Chimney (locomotive)|locomotive chimneys]] or [[Funnel (ship)|ship chimneys]], the word '''funnel''' can be used too.<ref>{{Cite web |url=http://angeles.sierraclub.org/hps/signatures/24h.htm |title=C.F.

Tall chimneys also allow [[chemicals]] to self-neutralize in the air before they reach the ground. == References == {{reflist}} [[Category:Architectural elements]]
