Column What Does Clean Coal Mean And Can It Save The

Coal is basically the fossilized mud of ancient swamps and bogs. The energy stored in coal was originally captured through plant photosynthesis in the swamps of the Carboniferous period, 300 million years ago. Unfortunately, those ancient wetland plants and microbes didnt just concentrate carbon, they also accumulated every kind of element in their tissues. Wetlands are natures water filtration systems, so they capture many contaminants 8212 and those ancient wetlands were also quite good at con

When we burn coal, we undo this long-term sequestration, producing soot and volatile gases that pollute our atmosphere alongside the energy. Throughout the world, many people still burn coal inside their own homes, paying the cost of cooking and heating with coal by breathing in the associated soot and sulfur.

In the developed world, we have been working on ever cleaner ways to burn coal since the first coal-fired generator began running in England back in the late 1800s. First, we moved away from burning coal inside our homes, concentrating the production of soot into a few large power plants and moving the soot plumes outside of cities. Then we began to make our smokestacks taller, so that pollution plumes would be lofted higher and distributed more broadly downwind of power plants.

To deal with this new problem, we began outfitting our power plants with filters to retain particulates and scrubbers to trap the sulfur gases that were generating acid rain.

A process flow diagram for a typical coal cleaning plant is presented in Figure 11.10-1. In the initial preparation phase of coal cleaning, the raw coal is unloaded, stored, conveyed, crushed, and classified by screening into coarse and fine coal fractions. The size fractions are then conveyed to their respective cleaning processes. Fine coal processing and coarse coal processing use similar operations and

Is Clean Coal Really Clean The Straight Dope

Achieving cleaner emissions from the smokestacks of coal-fired power plants requires trapping ever larger quantities of coal combustion residues. These byproducts of coal combustion are one of the dirty truths about clean coal. The trace metals, sulfur, and carbon dioxide that are not being emitted to the atmosphere have to be disposed of. We have reduced regional acid rain problems through the concentration of coal waste into metal and trace element enriched fly ash and gypsum.

Columns are often discounted as roughers because of the beliefs that a mechanical cells will provide ahigher level of recovery, and, b higher recovery provides more revenue than higher grades. For simple ores, this ismay be true. For more complex ores containing impurities which translate into additional treatment and refiningcharges, or for mines located in very remote regions, the benefit of being able to produce high grade concentrateseven at the expense of a slight reduction in recovery, may
