Good coating formation is only possible if the inner surface is cold enough for the liquid to solidify upon contact. The use of a narrow flame in a cement rotary kiln is extremely important since a divergent flame that impinges upon the lining will strip off the coating, resulting in very high kiln shell temperature and short refractory life.
