The chimney on top of a factory or a ship can be called a smokestack.
Why do factories have smokestacks?
A smokestack, stack, or chimney is a tall vertical pipe or channel used by power plants to exhaust combustion gases into the air. This height disperses pollutants over a wider area in order to minimize their impact. … Also, by building stacks higher than inversion layers the gas can be dispersed even more effectively.
What is a stack in a factory?
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.
What is stack example?
Therefore, a stack is referred to as a Last-In-First-Out (LIFO) list. Examples of stacks in “real life”: The stack of trays in a cafeteria; A stack of plates in a cupboard; A driveway that is only one car wide.
What is the white smoke from factories?
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 does smokestack slang mean?
Smokestack meaning

How can pollutants be removed from smokestacks?
Install an electrostatic precipitator (ESP) component, which is a particle control system that helps remove particles from a smokestack by using electrical charges. According to the U.S. Environmental Protection Agency, an ESP can remove small particles with up to 99 percent efficiency.
What did people use before chimneys?
Before the chimney, smoke from the fire set on a clay or brick surface in the center of the house would fill the house, escaping either through a hole in the roof or a hole in the wall made for that purpose. Most enclosed houses remained smoke filled buildings.
Why chimney is used in boiler?
A Chimney is a self standing structure for venting hot gases from a boiler to the outside atmosphere and to disperse them at a considerable height.
How does a chimney create draft?
An operating chimney is an enclosed column of warm air or gases surrounded by colder outside air. The warm air or gas in the chimney is more buoyant than the dense cold outside air so it rises, producing draft in the system.
Why poisonous gases from a factory chimney can affect a large area?
Yes, When burned, these fossil fuels emit harmful gases including carbon dioxide and sulfur dioxide which increase the amount of greenhouse gases in the atmosphere resulting in global warming. Air pollution is much worse in highly populated cities where more factories emit pollution in close proximity to humans.
How do smokestacks affect the environment?
Coal power plants use tall smokestacks to release air pollutants like sulfur dioxide and nitrogen oxides high into the atmosphere, in an effort to disperse pollution and decrease the impact on the local community. … “Stack height is one of several factors that contribute to the interstate transport of air pollution.
Should tall smokestacks be banned?
Should the construction of tall smokestacks be banned in an effort to promote greater emphasis on preventing air pollution and acid deposition? … Yes because smokestacks are a point source pollution that emits lots of greenhouse gases into the atmosphere.
What technology is used to reduce acid emissions from smokestacks?
Removing Pollutants from Smoke Stacks
The choice of technologies includes electrostatic precipitators, fabric filters, venturi scrubbers, cyclones and settling chambers.
Is smokestack a word?

Is white smoke toxic?
In general, thin white exhaust smoke (similar to water vapor) could be nothing to worry about. Depending on the outside temperature, condensation will build up inside of your car’s exhaust system and the heat heading through the pipes will create steam.
Where is stack used?
Stacks are used to implement functions, parsers, expression evaluation, and backtracking algorithms. A pile of books, a stack of dinner plates, a box of pringles potato chips can all be thought of examples of stacks. The basic operating principle is that last item you put in is first item you can take out.
