before it enters the kiln. The induced draft (ID) fans extract the hot gases from the kiln, heating the raw material as it swirls through the cyclones. Challenge The ID fans are a major consumer of electrical energy. Previ-ously the fans were controlled by sub-synchronous cascade converters. Cascade converters, however, have a restricted


re FAN EFFICIENCY FORMULA DERIVATION. Dear Ted. thanks a lot but. eff. = m3/s * Pa divided by motor kw. Now . 1mmwc = 9.8 Pa. so put 1Pa = 0.102 mmwc. efficiency = m3/s X 0.102 mmwc *100/( motor kw x motoe eff.) so 102 value comes in numerator instead of denomenator. Still it is not clear. Please do reply . Sidhant . Reply
