A chimney is a vertical pipe or structure, usually made of bricks, concrete or metal, that is used to carry smoke and gases from a fireplace, wood stove, furnace or boiler to the outside atmosphere. It is used to prevent the harmful gases and smoke from penetrating inside the room or house. It also helps in maintaining the proper air flow for combustion and preventing fires by removing the combustible gases and smoke outside. Chimneys are essential for the proper functioning of most heating systems that burn wood, coal, oil, gas or other fuels.
