Combustion Booklet 2013 Effect of burning different fuels There
are many varieties of coal being used in combustion processes
around the world; the most widely used are anthracite,
bituminous, sub-bituminous, and lignite. When burning coal a
considerable amount of carbon dioxide is generated given the
extremely high levels of carbon in coal; since carbon requires
more oxygen to burn, more combustion air is needed to burn coal
that other fossil fuels. In addition to the carbon dioxide
emissions, coal burning creates some other pollutants including
NOx, sulfur dioxide (SO2), sulfur trioxide (SO3), and particle
emissions. Sulfur dioxide chemically combines with water vapor
in the air to produce a weak form of sulfuric acid, one of the
main causes of acid rain. Oil fuels are mostly a mixture of very
heavy hydrocarbons, which have higher levels of hydrogen than
those found in coal. At the same time, oil contains less carbon
than coal and therefore re
