Why do factories have long chimneys?

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.

Do factories have long chimneys?

Answers. Factories have long chimneys as they have a special device called as electrostatic precipitator installed inside the chimneys. Electrostatic precipitators act as emission control units which trap dust particles, soot particles from the gases that are ready to be released out of the chimneys.

What is the role of chimneys in factories Class 6?

What is the role of long chimneys in factories? Answer: Burning of fuel takes place in factories, it produces smoke which contains a few harmful gases and fine dust particles. The chimneys in factories take the harmful smoke and gases away from us.

How are the tall chimneys installed in industries helpful in controlling air pollution?

Modern industrial chimneys help to reduce air pollution as they are too long and extend high in air. As, these chimneys are long they expel this harmful gases away from the people. Also the modern chimneys are fitted with filters which trap the dust and particulate mater present in the polluted air.

Why are chimneys there in the city and what is their harm?

pollution and could lead to several dangerous diseases like Asthma and Bronchitis. In order to prevent all this from taking place, nowadays filters are being attached in those chimneys which trap harmful and poisonous substances in the air being emitted outside by the chimneys.

How does chimney reduce air pollution?

The height of a chimney influences its ability to transfer flue gases to the external environment via stack effect. Additionally, the dispersion of pollutants at higher altitudes can reduce their impact on the immediate surroundings.

What is used in the chimneys of factories to prevent air pollution?

Modern industrial chimneys help to reduce air pollution as they are too long and extend high in air. Also the modern chimneys are fitted with filters which trap the dust and particulate mater present in the polluted air. Thus, decreasing the amount of pollutants in it and making it comparatively clean.

Why are chimney installed in the city?

Why are industrial chimneys 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.

How does industrial chimney work?

The principle behind chimneys is that warm air goes up above cooler air. Thus, a temperature difference exists between the inside of the flue and the room because of passaging hot air emerging from the flame. The quicker the air rises and hotter the fire is, the greater the chimney operates.
