Dear all

Kindly , its first time i ever seen this equation to calculate the thermal load at rotary kilns . can any one explain and clarify what the possible  way to calculate the percentage of calories in the main burner ppal

CT = LOAD THERMAL = 0.23 Tpd ^ 0.2 * ( % ppal )^ 0.34

Tpd = production level = 10.28 . Di ^3.48 / 0.06 . ( % ppal ) ^ 0.72

Where Di = Ferrule internal Diameter

Regards

ILA
