catastrophic climate change, then the car has to go. We cannot afford to burn that much carbon, and once oil runs short, the amount of carbon burnt will get worse as we revert down the chain to burning coal. Renewables will never provide enough energy. China did very well without the car until 10 years ago, India about 20 years ago.

In addition to the use of the latter, peat, petroleum, coke, coke brieze, lignite, and other low grade coals can be used, which, under present conditions, are unsatisfactory for steam production in a locomotive. On an engine fitted with an apparatus for burning powdered coal the coal powder is blown into the furnace by a soft air blast.

Place the ignited charcoal tablet "bowl" side up (if your tablet is indented) directly in the middle of your sand and/or ash and wait at least five minutes for it to burn and turn a light grayish hue before placing any incense on top of it. Once your charcoal tablet looks kind of like an eyeball, it's ready for incense!

Coal ash, also referred to as coal combustion residuals or CCRs, is produced primarily from the burning of coal in coalfired power plants. Coal ash includes a number of byproducts produced from burning coal, including: Fly ash, a very fine, powdery material composed mostly of silica made from the burning of finely ground coal in a boiler.

Burning the coal in the combustion process to release the energy in the fuel. Why Pulverizing ? The basic requirement of coal combustion is that all the carbon particles in coal should get sufficient air to burn and release the heat. Coal normally is available to power plants in large lumps ranging from 2 mm to 50 mm size.

Coal is a combustible black or brownishblack sedimentary rock, formed as rock strata called coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is a type of fossil fuel, formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.

The large chunks of coal are first crushed into a fine powder. This is called pulverisation. The coal is then transported to a furnace where it is burnt. The thermal energy from the burning coal is used to boil water and generate steam. The steam pushes the blades of the turbine and so the turbine spins.

Why are we still burning coal? Coal warms our hospitals and schools, ripens our tomatoes, makes roses bloom, turns ironsand into steel, dries milk powder for export, and generates electricity when hydro lakes are low and gas production sputters.

During the coal boom of the 1970s, slurry pipelines were proposed as an alternative to rail transport. Coal would be crushed, then mixed with water to create a slurry and sent via pipeline to its destination, where the mixture was dried, then burned. When in the pipeline, the slurry moved along at a leisurely four miles an hour.
