Gas Turbines: Introduction, Types, Working Principle

The pulverised coal may also be used as a fuel in gas turbine plant. But it may contain as much as 5-10 percent of its weight of dirt in the form of ash. In case, the ash particles are allowed to pass through the turbine the latter''s blades are likely to be blocked and even damaged.

How much CO2 and pollution comes from burning coal?

Burning coal creates pollutants like CO2, NOx, SO2 and mercury. We do the math on how much pollution is released if you power a 100 watt bulb for a year. A concentration of 5ppm in a ton of coal means about 0.01 pound, or 0.16 ounces, or 4.5 grams of
