-crushing the coal into small chunks and washing out the sulfur dioxide.
-burn the coal, reducing the NOx. this is called 'staged combustion'.
-using a 'fluidized bed boiler', realising the sulfur dioxide, then the limestone captures the sulfur and changes it into calcium sulfate.
hope this helps...its just a rough draft of how clean coal tech can be done though.
What else can I help you with?
How important is it to use clean coal technology?
It is very important to use clean coal technology. The pollutants from burning coal causes health problems as well as environmental problems. The clean coal technology cuts back on these pollutants and provides a cheap form of energy.
Is clean coal renewable or nonrenewable?
clean coal is not renewable
What has the author Bruce G Miller written?
Bruce G. Miller has written: 'Clean coal engineering technology' -- subject(s): Clean coal technologies, Environmental aspects, Coal-fired power plants, Coal-fired furnaces, Coal
What type of clean coal technology reduces the most amount of carbon dioxide?
Some clean coal technology that reduces the emissions of green house gas, includes the 'Oxy Fuel CCS Power Plant'. This technology filters the and clean the carbon dioxide before storing in in the underground layer. This technology was invested by the government officials to tackle the global warming issues.
Why is clean coal technology a temporary solution?
Clean coal technology is considered a temporary solution because it still produces greenhouse gas emissions, though at lower levels than traditional coal plants. In the long run, transitioning to renewable energy sources like solar and wind power is more sustainable and environmentally friendly. Additionally, clean coal technology can be expensive to implement and maintain, making it less viable in the long term.
Why is clean coal now being promoted in commercials?
I do not know as a fact that clean coal is being promoted more now, than before. I have no inside industry information on this subject. I've included a number of links on the "clean coal technology", with the first two links, spoofing the clean coal ads. So the clean coal ads have had a backlash on the internet. All companies in the coal industry have public relations departments, which promote environmentally safe practices and advances in technology to minimize pollution. Also, there are non-profit organizations, such as the American Coalition of Clean Coal Electricity, funded by energy companies. The list of the companies that are members is provided on their website. (see related link) If there is an increase in clean coal technology promotion (and I don't know if this is true), it may be due in part to the numerous efforts worldwide to curb carbon emissions based on climate change concerns. From the perspective of a coal company, there is always concern that there will be more regulatory action, making it more expensive to generate electricity. See related links.
How does clean coal benefit the environment?
'Clean coal' is a hope that one day we will be able to trap and safely dispose of the carbon dioxide emissions from burning coal. So far this has not been done successfully or economically. Many people think it will never happen.
Do coal companies have the technology to make clean coal?
No, fossil fuel companies do not have the technology to make fossil fuels clean. Fossil fuels come from, as the name suggests, dead plants and animals with millions of tons of pressure on their decomposing bodies for hundreds of millions of years, therefore there is so much carbon built up in them that it is impossible to make them clean. Also, even if they did, they would be to worried about money to actually employ this technology.
How does clean coal reduce the emission so2?
"Clean coal" primarily from the Powder River Basin, is low in sulfur content compared to other coal sources, and therefor produces less SO2 when combusted. " Clean Coal Technologies" use chemical methods of "scrubbing" SO2 from exiting flue gasses before they can be released to the environment. One byproduct of this technology is gypsum which can be used in wall board for construction.
What can be done for coal to be environmental friendly?
There is talk of carbon catchers to block and hold released carbon, but there is still not any implemented technology that makes burning coal any less pollutant.
Why cant the people financialy support companies like MDI compressed air cars to bring clean technology to the market?
How do you think the air gets compressed? Its not a clean technology it only makes people think its clean just like electric cars. Coal creates more then half the electricity in the U.S. All your doing with your hybrid car is polluting the planet with coal rather then gas so don't think your doing the world a favour.
Why is coal mining done?
Coal is an energy source.
