Cement kiln thermal loading

Re: Thermal Loading in the Kiln. Maximum thermal loading in the dimension kiln can be 5.4Gcal/hr/m2.Higher thermal loading certainly put thermal stress in kiln refractory but refractory solution present for high thermally loaded kilns such as magnesia-zirconium oxide brick for lower transition zone.Optimum degree of calcination we may achieve 90-95%.More than 95% calcination

    However, new cement kilns are of the 'dry process' type. Dry process kilns. In a modern works, the blended raw material enters the kiln via the pre-heater tower. Here, hot gases from the kiln, and probably the cooled clinker at the far end of the kiln, are used to heat the raw meal. As a result, the raw meal is already hot before it enters the
