Rational Allocation Rotary Kiln And Calciner Air Flow Capacity:

Rotary kiln and calciner air flow capacity allocation is through kiln tail necking and tertiary air duct  valve open degree to realized. Under normal production condition, you should control oxygen contain about 1%, at kiln tail oxygen contain about 3%. If kiln tail oxygen contain too high, because inner kiln air flow capacity is too big. If kiln tail oxygen contain too low, kiln head with low pressure, lead to coal burning with less temperature point, because inner kiln air flow capacity is too less, can't meet inner air flow capacity requires.
