The liquid percentage at 1450 0 C can be estimated using the formula. % Liquid content (1450 0C) = 3.0 x A+2.25 x F+S. Where A=Al 2 O, F=Fe 2 O 3, S= MgO+K 2 O+Na 2 O+SO 3 In Clinker. The normal range of liquid phase is 22-27%. Burnability is a reference value for raw meal indicating how difficult it is to burn.
Installation innovations. “Bringing material up to temperatures as high as 1315 °C takes a tremendous amount of energy,” said Dev. “The cost of downtime for cooling the preheater tower, performing the work and reheating the kiln is astronomical. The ability to avoid shutdowns and yet safely service these systems has been a fundamental ...
