A smokestack industry is a basic, usually cyclical, manufacturing industry. [1] The factories stereotypically used in such industries have flue gas stacks, hence the name, and produce a high volume of pollution. During the earliest era of electric power development, coal fired electric stations in urban areas were common prior to the use of Alternating current for lighting as Direct current electricity could only travel short distances.

Example industries include:

Smokestacks are large industrial chimneys used in the process of combusting mostly fossil fuels in furnaces with the goal of producing steam to drive generators for electricity, for the smelting ores, or as a separation or refinery process. The carefully constructed circular stacks were used to both increase the flow of combustible air but also isolate exhaust gases, carbon dioxide and pollutants from ground level releases during ever larger industrial activities. The difference in temperature between the bottom inside and outside of the stack helped to increase the rate air flow through the furnace known as the stack effect.

History

Smokestacks were first used during Industrial Revolution between the 18th century and 19th centuries and were known to foul the airs in most larger cities but were most noted in large industrial centers like Manchester England or Pittsburgh Pennsylvania. During the dramatic growth and evolution of systems used to produce electricity coal burning central electric stations that relied on direct current were found throughout cities that released noxious fumes and soot into the city air. Taller smokestacks helped to reduce this environmental issue. During the 20th century fans were used to increase air currents needed in furnaces while heights that reached 1,300 feet grew as a way to comply with environmental safety regulations passed by governments.

A power station, also referred to as a power plant and sometimes generating station or generating plant, is an industrial facility for the generation of electric power. Power stations are generally connected to an electrical grid.

A chimney is an architectural ventilation structure made of masonry, clay or metal that isolates hot toxic exhaust gases or smoke produced by a boiler, stove, furnace, incinerator, or fireplace from human living areas. 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 effect. The space inside a chimney is called the flue. Chimneys are adjacent to large industrial refineries, fossil fuel combustion facilities or part of buildings, steam locomotives and ships.

Coal gas is a flammable gaseous fuel made from coal and supplied to the user via a piped distribution system. It is produced when coal is heated strongly in the absence of air.

<span class="mw-page-title-main">Fossil fuel power station</span> Facility that burns fossil fuels to produce electricity

A fossil fuel power station is a thermal power station which burns a fossil fuel, such as coal, oil, or natural gas, to produce electricity. Fossil fuel power stations have machinery to convert the heat energy of combustion into mechanical energy, which then operates an electrical generator. The prime mover may be a steam turbine, a gas turbine or, in small plants, a reciprocating gas engine. All plants use the energy extracted from the expansion of a hot gas, either steam or combustion gases. Although different energy conversion methods exist, all thermal power station conversion methods have their efficiency limited by the Carnot efficiency and therefore produce waste heat.

The Lakeview Generating Station was an Ontario Power Generation coal-burning power station located in Mississauga, Ontario, Canada, in the Lakeview neighbourhood on Lakeshore Road just east of Cawthra Road. The former station, constructed in 1958–1962, had four smokestacks known as the Four Sisters; the eight boilers of the generating plant all 'twinned' their emissions into common stacks. The station was a landmark for years and was shut down in April, 2005, after 43 years of service. The four stacks, which could be seen from as far away as Burlington to the west and downtown Toronto to the east, were demolished on June 12, 2006. The rest of the building was demolished on June 28, 2007.

<span class="mw-page-title-main">Flue-gas stack</span> Stack

A flue-gas stack, also known as a smoke stack, chimney stack or simply as a stack, is a type of chimney, a vertical pipe, channel or similar structure through which combustion product gases called flue gases are exhausted to the outside air. Flue gases are produced when coal, oil, natural gas, wood or any other fuel is combusted in an industrial furnace, a power plant's steam-generating boiler, or other large combustion device. Flue gas is usually composed of carbon dioxide (CO2) and water vapor, as well as nitrogen and excess oxygen remaining from the intake combustion air. It also contains a small percentage of pollutants such as particulate matter, carbon monoxide, nitrogen oxides and sulfur oxides. The flue gas stacks are often quite tall, up to 420 metres (1,380 ft), to increase the stack effect and dispersion of pollutants.
