Clinker burning, coating formation, flame - SlideShare

Apr 05, 2013 · Clinker burning 1)Radiation of heat from flame to refractory Heat 2)Conduction of 1400 deg c heat from refractory to charge 3)Convection of 1900 1350 deg c heat from 1450 ded c particle to particle while rotating.Higher rpm 1500 deg increases the rate of convection Higher rpm improves the thermal distribution,better heat exchange between refractory and raw meal bed and so reduces the radiation .

How We Burn Fat | HowStuffWorks

How We Burn Fat. Prev NEXT . Fat cells lie behind how you gain and lose weight. HowStuffWorks According to the law of conservation of mass, matter is neither created nor destroyed, but it may alter its form through chemical reaction. Essentially, that tells us that while we lose mass in our bodies by burning up fat, it does not just disappear.

POLFLAME clinkering zone burner. - polysiususa

POLFLAME®. By adjusting the swirl and divergence settings of the nozzles, the reaction zone can be significantly shortened, in-creasing the flame temperature and making the combustion more intensive. This is particu-larly advantageous when burn-ing slow-reacting secondary fuels that are difficult to ignite, or when burning anthracite coal.
