Coal is the main source of electricity generation in fossil fuel based power plants. The use of coal in coalfired power plant (CFPP) causes raise in global temperature due to greenhouse gases emission responsible for global warming across the globe [1, 2]. It also has an adverse impact on the health of human being.
