What are benefits of using coal energy?
One benefit to using coal energy is that the leftover ash from burning coal, called fly ash, can be used to make a cement paste when mixed with alkaline chemicals like sodium hydroxide (NaOH).
What can coal be turned into?
Coal can be turned into carbon dioxide that contains some of these mixed in: water vapor, sulfur dioxide, nitrogen dioxide, carbon monoxide, and ammonia.<br> Also, when you burn coal, you get some solid stuff called "coal ash" or "fly ash" which is somewhat like sand or dirt particles. ------------------------------------------------------------------------------ Otherwise, you can bake coal in an airtight oven, and from that you get a thick oily substance called "coal tar", which can sometimes be used in medicines (in very small amounts), a complicated substance, and you also get ammonia, hydrogen sulfide, and other poisonous substances, PLUS you get a solid substance called "coke" that is made of nearly 100 percent carbon. Coke is good for making iron and steel, and in smelting some other metals, and you can use it to heat up your house if you can get it an you burn it very carefully.
What pollution is produced from coal?
When you burn coal to generate electricity (or even to heat your home) the gas going up the chimney contains carbon dioxide, water vapor, nitrogen, nitrous oxides, sulfur oxides, fly ash and mercury. There is also solid waste ash that must be removed afterwards, though some of this can be used in building. The carbon dioxide and water vapor it emits contributes to greenhouse gases. The other toxic gases pollute the air and are often collected by raindrops and turned into acid rain with the resultant damage to the environment.
Why should you not burn coal?
We should not burn coal because it gives off large amounts of carbon dioxide which adds the the greenhouse gases in the atmosphere, contributing to global warming. There is also a fine solid called fly ash which, if inhaled, is extremely dangerous to humans as well as other forms of life.
What is the name of coal ash?
Coal ash is a general term...just like soda is a general term. Soda comes in many varieties and mixtures...likewise coal ash varies tremendously depending on the source and contents. Coal ash also has many other "names" such as Coal Combustion Residuals (CCRs), Coal Combustion Byproducts (CCBs), Coal Combustion Wastes (CCWs) and Fossil Fuel Combustion (FFC) wastes, but generally it is a term that collectively includes materials such as coal: fly ash, bottom ash, boiler slag, and flue gas desulfurization materials. Coal is a rock made from formerly living green plant etc material...hence it contains carbon combined with indigenous rock/dirt/soil commonly found in the coal mining region. Carbon is a substance that "burns" and generates BTU's. Accordingly coal ash is a mixture of the indigenous rock/dirt/soil found in coal (and the local area) minus the carbon. The ash material has been safely and beneficially used since the time of the Roman Empire. Today in many states it is beneficially used in a highly regulated fashion...some of the many beneficial uses are: 1.Concrete/concrete products/grout 2. Blended cement/raw feed for clinker 3. Gypsum panels (e.g., wallboard) 4. Flowable fill 5. Structural fills/embankments 6. Road base/sub-base/paving 7. Soil modification/stabilization 8. Mineral filler in asphalt 9. Snow and ice control 10. Blasting grit-Roofing granules 11. Mine placement/reclamation 12. Waste stabilization/solidification 13. Agriculture 14. Aggregate
What is the class of a fly?
fly ash nothing but the coal
What is the specific gravity of fly ash?
specific gravity of fly ash is 3.2
What has the author Robert H Davis written?

When did Kingston Fossil Plant coal fly ash slurry spill happen?
Kingston Fossil Plant coal fly ash slurry spill happened in 2008.

Is pumice fly ash?
No. Fly ash is ash left over from burning coal. Pumice is a porous rock produce during some volcanic eruptions.
What is the specific heat of fly ash?
It would be about the same as sand (0.8 kJ/kg.K) See Link for typicals for several materials.
How many tons of fly ash are equal to one cubic meter of fly ash?
1.2 metric tons equals 1 cubic meter of Fly ash (one of the residues of coal combustion).
What is flyash?
Fly ash is one of the residues generated in combustion, and comprises the fine particles that rise with the flue gases. In an industrial context, fly ash usually refers to ash produced during combustion of coal.

What is the disadvantages of coal?
it causes most polution, releases impurities such as sulfer, nitrogen, and fly ash which can lead to acis rain.
