-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.

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
Why is clean coal technology a temporary solution?
Because coal is a non-renewable fossil fuel that will run out someday.
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 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.
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 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.
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 are some disadvantage of clean coal?
Some disadvantages of clean coal is that it pollutes the air.
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.
What is clean coal - or green coal?
Burning of coal, a fossil fuel is one of the principal causes of climate change and global warming."Clean coal" or "Green coal" is a theory that we can capture all the pollutants including sulphur dioxide and carbon dioxide from coal as it is burnt and store them, instead of releasing them as greenhouse gases.The carbon dioxide will then be pumped underground into vacant spaces where oil and natural gas used to be. This will be known as "carbon sequestration".Countries that rely on coal for their economies and electricity generation (Australia, for one) are hoping that clean coal will let them continue using and exporting "clean" coal without the carbon pollution attached.Unfortunately there are no examples of successful coal "cleaning" so far.Many environmentalists believe that the term clean coal is misleading: "There is no such thing as 'clean coal' and there never will be. It's an oxymoron" (Sierra Club director, Dan Becker).Complaints are:Coal mining has a high environmental impactCarbon Sequestration costs will be extremely highThere is no sure science on how to capture or store the pollutants.A: Clean coal is essentially a lie made up by politicians to fool voters into believing the government is acting on the energy crisis. In the real coal industry, "clean coal" has been implemented in 6% of coal-power stations, and is now no longer being used in any stations. The chemistry behind clean coal produces highly toxic chemicals as a by-product, and hence cannot be used to fix the energy crisis. It certainly isn't good for the environment. As an example of the difficulties involved, Australia's coal-fired power stations produce 260 trillion liters of carbon dioxide every day (260,000,000,000 liters). The energy required to compress and sequester this would use massive amounts of the power generated by the "cleaned" coal.Clean coal is a term for technology (Clean coal technology) that mitigates emissions of carbon dioxide (CO2) and other greenhouse gasses that arise from the burning of coal for electrical power. It reduces the harmful emissions caused by the burning of fossil fuels.coal that is burned with technology that cuts the amount of soot and sulfur dioxide emitted
