Using a method called flue gas desulphurisation which involves the addition of a calcium oxide. The calcium oxide basically absorbs the sulphur dioxide on its way out of the flues; economically, useful products are produced such as gypsum which can be used as plaster.
Sulfur dioxide emissions can be reduced in coal-fired power stations by installing pollution control technologies such as Flue Gas Desulfurization (FGD) systems or by using low-sulfur coal. FGD systems work by capturing sulfur dioxide from the flue gas before it is released into the atmosphere. Switching to low-sulfur coal reduces the amount of sulfur dioxide produced during combustion.

How is sulfur dioxide removed from coal fired power stations?
Sulfur dioxide in coal-fired power stations is typically removed using a process called flue gas desulfurization (FGD). This can be done through methods such as scrubbing with a limestone slurry or using specialized equipment like dry sorbent injection systems. These processes help to capture and neutralize sulfur dioxide before it is released into the atmosphere.
How is calcium carbonate used in coal fired power stations?
Calcium carbonate is commonly used as a sorbent to remove sulfur dioxide (SO2) emissions from flue gas in coal-fired power stations. When calcium carbonate reacts with SO2, it forms calcium sulfate, which can be captured and disposed of. This process helps to reduce air pollution and comply with environmental regulations.
What gases are released from coal fired power station?
Coal fired power stations release carbon dioxide (CO2), sulfur dioxide (SO2), nitrogen oxides (NOx), and particulate matter (PM) into the atmosphere. These emissions contribute to air pollution and global climate change.
Why are waste gasses from coal-fired power stations passed through calcium carbonate?
Waste gases from coal-fired power stations are passed through calcium carbonate to remove sulfur dioxide from the gas stream through a process known as flue gas desulfurization. In this process, the calcium carbonate reacts with the sulfur dioxide to form calcium sulfate, a solid compound that can be easily removed, reducing air pollution and environmental impacts.
Which country produced the most sulfur dioxide?
China is the largest producer of sulfur dioxide emissions in the world, with a significant portion coming from industrial activities such as coal-fired power plants and manufacturing.

What are the two chemical pollutants that are produced by coal fired power stations?
The two main chemical pollutants produced by coal-fired power stations are sulfur dioxide (SO2) and nitrogen oxides (NOx). These pollutants are released into the atmosphere during the combustion of coal and contribute to air pollution and adverse health effects.
Why is wet powdered calcium carbonate sprayed through the waste gasses in a chimney of a coal fired power station?
Wet powdered calcium carbonate is sprayed through waste gases in a chimney of a coal-fired power station to remove sulfur dioxide (SO2) from the emissions. The calcium carbonate reacts with the sulfur dioxide to form calcium sulfate, which can be disposed of safely. This process helps reduce air pollution and adheres to environmental regulations.
How could power stations reduce the amount of carbon dioxide they produce?
There are many ways to generate electricity. Methods that burn fossil fuels (coal, oil and natural gas) produce carbon dioxide. Methods using renewable energy do not. Nuclear power plants, although uranium in non-renewable, do not produce carbon dioxide. Power stations could be rebuilt to use different fuel sources. Biomass and biofuel will power a coal fired power station without emitting the carbon dioxide pollution.
Why sulfur emissions from coal-fired power plants are considered an environmental problems?
Sulfur emissions from coal-fired power plants contribute to air pollution by forming sulfur dioxide (SO2), which can react with other compounds in the atmosphere to form acid rain. This can harm ecosystems, damage buildings and infrastructure, and pose health risks to humans. Additionally, sulfur dioxide can contribute to the formation of fine particulate matter, which can negatively impact air quality and human health.
Are green house gases more or less than carbon dioxide?
Carbon Dioxide IS a 'greenhouse gas' ! There are still too many coal-fired power stations that are releasing tons of CO2 into the atmosphere !
What is bad about gas fired power stations?
Gas fired power stations contribute to global warming by releasing greenhouse gases such as carbon dioxide. They also require extraction and transportation of fossil fuels, which can have negative environmental impacts. Additionally, there are concerns about the potential for gas leaks and accidents at these facilities.
What is two thirds of the sulfur dioxide that pollutes the air produced by?
Sulfur dioxide in the air is mainly produced by burning fossil fuels like coal and oil. Two thirds of this pollution comes from coal-fired power plants, industrial processes, and automobiles.
