What is a factory smokestack?
Smokestacks are chimneys needed for factories that burn fossil fuels, such as coal, in order to create steam to power generators in order to create electricity for the factory’s purpose, such as with a coal plant.
How tall is the average smokestack?
As a result, companies began building taller and taller smokestacks. The average stack height increased from about 200 ft (61 m) in 1956 to over 500 ft (152 m) in 1978. The tallest stack in the United States in 1956 was under 600 ft (182 m) tall, but a decade later, some stacks were more than 1,000 ft (305 m) high.
What is the diameter of a smoke stack?
They take several readings of the flow at various points within a cross section of the stack, which is typically 7 or 8 meters (25 feet) in diameter.
Why are old smokestacks so tall?
A smokestack, stack, or chimney is a tall vertical pipe or channel used by power plants to exhaust combustion gases into the air. This technique is to build the stack very high, because wind speeds are greater at high elevations, and the dispersion of the gases results in less gas remaining in a given area.
Why is factory smoke white?
While filtering the dust, the high heat in the exhaust gas is also absorbed by the water, and the water vapor is discharged from the chimney. When it is cold, it is the white smoke we see. This can also be a side note that the pollutants emitted by the boiler comply with national emission standards.
What is the tallest smokestack?
GRES-2, commissioned in 1987, has installed capacity of 1,000 MWe and has the world’s tallest flue-gas stack at 419.7 metres (1,377 ft) high. The reinforced concrete chimney is about 38 metres (125 ft) taller than the Inco Superstack in Sudbury, Ontario, Canada. It is the tallest chimney ever built.
What is the tallest smokestack in the United States?
1,217 feet tall
Homer City, Pennsylvania: Tallest Smokestack in the U.S. 1,217 feet tall.
How tall should a smoker chimney be?
The most common of these being the 2 foot, 10 foot, 3-foot rule. Roughly this means that a chimney should be 3 feet higher than the point it passes through a roof, while also being at least 2 feet taller than any part of a building that’s within 10 feet of the chimney.
Why should the factory chimneys be tall?
Long chimneys take the harmful smoke and gases produced in the factories high up in the air so as to reduce its harmful effects on the ground.
Why were Victorian chimneys so tall?
The higher the chimney (a containment of hot air) the faster the gases and the more air / oxygen drawn in supplying fire with more heat potential.
What is a smokestack industry?
A smokestack industry is a basic, usually cyclical, manufacturing industry. The factories stereotypically used in such industries have flue gas stacks, hence the name, and produce a high volume of pollution.
What is a smokestack furnace?
A factory or industrial furnace can often be distinguished by its smokestacks, which are often built quite high to allow for a wider and therefore less concentrated dispersal of pollutants. Smokestacks became common during the Industrial Revolution.
How tall is the Inco Superstack?
The Inco Superstack in Sudbury, Ontario is 380 meters tall, note the train at the bottom for a sense of how high it is (click to enlarge). A smokestack, stack, or chimney is a tall vertical pipe or channel used by power plants to exhaust combustion gases into the air.
Why are smokestacks so tall?
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.
