The Contemporary Coal Power Plant

[size=18]Comparison of Growth Areas and Emissions, 1980-2008
The graph shows that between 1980 and 2008, gross domestic product increased 126 percent, vehicle miles traveled increased 91 percent, energy consumption increased 29 percent, and U.S. population grew by 34 percent. During the same time period, total emissions of the six principal air …

well the post are interesting, there are few sites on the web that doesn't focus on the negativity alone of coal. albeit, I think it would be ok if we could open a discussion on other alternative sources for power.
coal power, yes, it is the now solution for power. But I'm open to the thought of "coal is not a permanent solution".

PROBLEM:

The negative side of energy use—pollution of the environment—is not a recent problem. In 1306 King Edward I of England so objected to the noxious smoke from London's coal-burning fires that he banned coal's use by everyone except blacksmiths. The enormous scale of today's energy use has increased environmental concerns.

Coal-fired electric power plants emit gases that are harmful …

Greenhouse emissions
>Obama wants Congress to set a cap on greenhouse emissions such as carbon dioxide. That would require companies to buy permits to emit greenhouse pollution.

Clean coal technology
>There is $3.4 billion in the stimulus bill for fossil-fuel research, including for technology that would allow coal-plant operators to bury carbon dioxide from the plant.

Upgrading the …

James Hansen, director of NASA's Goddard Space Institute, has recommended that no further coal plants be built that do not capture their carbon dioxide emissions, and has further …

At the bottom of the boiler furnace there is a bed of inert material. Bed is where the coal or fuel spreads. Air supply is from under the bed at high pressure. This lifts the bed material and the coal particles and keeps it in suspension. The coal combustion takes place in this suspended condition. This is the Fluidized bed.

Special design of the air nozzles at the bottom of the bed allows air …

This figure shows the relative fraction of man-made greenhouse gases coming from each of eight categories of sources, as estimated by the Emission Database for Global Atmospheric Research version 3.2. These values are intended to provide a snapshot of global annual greenhouse gas emissions

Sulfur is a yellowish substance found in coal. A way of removing sulfur particles from coal is to break it in small chunks then wash it.
Sulfur exist in specks called "pyritic sulfur" that of which can be washed out in large water filled tanks. Coal floats while sulfur sinks (due to it's dense properties). This is done in "coal preparation plants", which is a requisite for …

Coal plays a major role in energy generation. But with the past environmental hazards that it had brought us, the "world" now is more environmentally sensitive. As more and more the populace is experiencing the effects of climate change.
This brought about the changes in the "Coal power Plant Industries", researches and technologies have been made to effectively lessen the …
