Boiler Chimney

chimneys for venting hot flue gases or smoke from a boiler to the outside atmosphere. Boiler chimneys are typically vertical, or as near as possible to vertical, to ensure that the gases flow smoothly, drawing air into the combustion in what is known as the stack, or chimney.a vertical structure incorporated into a building and enclosing a flue or flues that carry off smoke. especially : the part of such a structure extending above a roof. smokestac, 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. This is called a “draught” and it forces air into the fireplace, this air feeds the flames as it rushes past the fire.Chimneys are ventilation channels that guide smoke and other gases that are products of combustion out from a fireplace through the roof of a building. Chimneys operate based on the principle that hot air is less dense than cold air, and thus rises.Industrial chimneys are vertical constructions created to reduce the impact of greenhouse gases and other industry substances on its immediate surroundings. These stonework (brick), concrete, or steel structures are used to eject gases generated by industries after completing their production processes.The word chimney comes ultimately from the Greek kaminos, "furnace," and in 13th-century Old French it became the more familiar looking cheminee, "fire place." As chimney fires became a serious problem, the chimney sweep became an important person, cleaning the soot from chimneys.
