WEBIn industrial chemistry, coal gasifiion is the process of producing syngas —a mixture consisting primarily of carbon monoxide (CO), hydrogen ( H2 ), carbon dioxide ( CO2 ), methane ( CH4 ), and water vapour ( H2O )—from coal and water, air and/or oxygen. Historically, coal was gasified to produce coal gas, also known as "town gas".
WEBReport: The diagram illustrates how electricity is generated from coal. Overall, the process has nine stages, beginning with the supply of coal and ending with the disposal of ash. First, the supply of coal goes into a pulverizer, a machine which breaks the coal into powder. Then, the dust from pulverizing the coal is collected before it enters ...
WEBElectricity is a secondary energy source. Electricity is the flow of electrical power or charge. Electricity is both a basic part of nature and one of the most widely used forms of energy. The electricity that we use is a secondary energy source because it is produced by converting primary sources of energy such as coal, natural gas, nuclear ...
