There are at least 2 reasons why cement kilns fired with natural gas are less productive than those fired with solid fuels i the combustion product gas volume is higher with natural gas due to its higher hydrogen content therefore the effective capacity of the induced draft fan of the kiln is reduced and ii the emissivity of a gas flame is lower than a coal flame due to the lack of particles to glow in the flame

Total flow precalciner In total flow precalciners combustion takes place in a mixture of kiln exit gases and tertiary air Combustion therefore starts in gases with about 10 to 14 oxygen and ends in about 1 to 3 oxygen Raw meal from the preheater is fed into the bottom of the precalciner and is conveyed through the precalciner to the lowest stage cyclone by the precalciner gases During this time fuel
