What does white smoke coming out of a chimney mean?
In fact, if the chimney emits black smoke, it usually represents pollution, but some white smoke is harmless, while some pollution is completely invisible. In fact, most of the white "smoke", especially in cold weather, only water vapor (and condensed droplets).
What is the smoke that comes out of a factory?
Some of the smoke is simply water vapor, which condenses into a whitish cloud before evaporating. Depending on the fuel and how it is burned, the smoke may also contain gases or particles that can be damaging to our health. Click to see full answer. Keeping this in view, what is the smoke that comes out of factories?
What does the smoke from a fire look like?
Some of the smoke is simply water vapor, which condenses into a whitish cloud before evaporating. Depending on the fuel and how it is burned, the smoke may also contain gases or particles that can be damaging to our health.
What is the thing smoke comes out of factories called?
Smog was common in industrial areas, and remains a familiar sight in cities today. Today, most of the smog we see is photochemical smog. Photochemical smog is produced when sunlight reacts with nitrogen oxides and at least one volatile organic compound (VOC) in the atmosphere.
What does smoke from factories cause?
Air Pollution The toxic gases that factories release into the air, combined with those added by automobiles on the road, mean that we have an increased risk of developing chronic respiratory disease, lung cancer, heart disease and many other illnesses, diseases and conditions.
What comes out of a factory chimney?
Smokestack Smoke and Air Pollution Fine particles come from burning fuels such as wood, oil, natural gas, gasoline and coal. Noxious gases include sulfur dioxide, nitrogen oxides, carbon dioxide, carbon monoxide and chemical vapors.
What do smokestacks release?
Tall smokestacks—which are used primarily at coal power plants—release air pollutants such as sulfur dioxide (SO2), and nitrogen oxides (NOx) high into the atmosphere to help disperse them and limit their impact on air quality in local communities.
What do factories release into the air?
In factories, toxic materials and gases, like carbon dioxide and methane, are burned and pumped out into the atmosphere. Carbon dioxide and methane absorb radiation from the sun and, therefore, affect the temperature of the planet directly.
What is factory smoke?
Factories contaminate the air by blowing chemical vapors and smoke out through vents and smokestacks, and by burning waste in open dumps or incinerators. Exhaust from generators, diesel trucks, and buses also fill the air with dangerous gases.
What is chimney smoke called?
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.
What type of mixture is smoke from a factory chimney?
Final Answer: Smoke is an example of solid in gas mixture.
Why do they light smoke stacks?
In industrial plants, flare stacks are primarily used for burning off flammable gas released by safety valves during unplanned over-pressuring of plant equipment. During plant or partial plant startups and shutdowns, they are also often used for the planned combustion of gases over relatively short periods.
Why is power plant smoke white?
The “smoke” coming out of the cooling towers of the nuclear power plants of Doel and Tihange is actually …… steam. This steam is not radioactive because it does not come into contact with the primary circuit.
What do flue stacks emit?
Combustion processes produce a variety of undesirable products depending on the type of fuel used. Because combustion is an oxidation process, flue gases contain carbon monoxide, carbon dioxide, sulfur oxides, nitrogen oxides, acids and aerosolized metal oxides.
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.
