Some Facts About COAL FIRED POWER PLANTS . SAY YES TO HYDROPOWER in Pakistan. A 1200 MW Coal Fired project (like in Sahiwal, if true) would produce 5 Million Tones of CO2 / Year. The only reasons they are built or built in Pakistan is the low cost, stable coal market and low grade cheap coal available causing following at its high. Air pollution consists of a mixture of chemicals with various harmful effects on the human body, wildlife, plants, and climate. Coal-fired power plants are responsible for release over 85% of total global carbon dioxide emissions, a prime contributor to global warming. Coal-fired power plants using pulverized coal or lignite as fuel generate large quantities of fly-ash as a by-product. With the increase in commissioning and large capacity and with the increasing use of low grade coal of high ash content, the amount of generation of ash from them is becoming very large. This poses serious ecological problems. Most of the ash generated from the power plants is disposed off in the vicinity of the plant as a waste material covering several hectares of valuable land. Looking into the nuisances poses by fly-ash; it has been well appreciated by everybody and various Government agencies, the need for the safe disposal and effective utilisation of fly-ash. The properties of fly-ash depend on several variables such as coal source, degree of pulverization, design of boiler unit, loading and firing conditions, handling and storage methods etc
