1) explore the 3 composition of coal and petroleum .which type of coal is used in thermal power plants?

  • 0
composition of coal
  • primary- carbon
  • secondary -hydrogen,sulphur,oxygen and nitrogen                             
​composition of petroleum
The hydrocarbons in crude oil are mostly alkanes, cycloalkanes and various aromatic hydrocarbons while the other organic compounds contain nitrogen, oxygen and sulfur, and trace amounts of metals such as iron, nickel, copper and vanadium.
Generally coal is used as a major fuel in mostly all the thermal power plants because it's the most abundant fossil fuel, easily available at relatively low cost.
