Coal pollution is widespread in areas that lie near coal reserves. When coal is burnt, it releases carbon dioxide in vast quantities, which is harmful to human beings. Moreover, coal is a non-renewable and exhaustive natural resource which implies that we should not depend on it for everyday activities.

May 09, 2019 Coal fly ash (CFA), a by-product generated from coal-burning power plants, readily leaches toxic elements into aquatic environments. The present study describes a classification system for CFA based on the chemical composition of CFA and leachability of toxic elements, which can promote the safe and effective utilization of CFA for uses such as fly ash cement. To classify CFA samples, the
Sep 01, 2021 Soft coal is also known as brown coal or lignite. China produces more hard coal than any other country by a factor of about three. The whopping 3,162 million metric tons of hard coal produced by China dwarfs the output of the second and third-ranked producersthe U.S. at 932 million metric tons and India at 538 million metric tons.
Feb 01, 2011 The ASTM coal rank classification is based on a number of parameters obtained by various prescribed tests, which include calorific or heating value, volatile matter, moisture, ash, and fixed carbon (Figure 4.10). Calorific or heating value of coal is defined as heat energy released as it undergoes complete combustion with oxygen.
