Three times the kiln diameter in length is a good tradeoff between efficiency and refractory service life. However irrespective of the shape the flame must not touch the refractory or serious refractory washing will occur. ROTARY KILN CHAIN SYSTEMS At the cold end of the kiln the relatively low gas temperature hampers heat transfer.
Rotary kiln. This is determined by i the maximum flow rate of the proposed burden through a kiln and ii the residence time at temperatures that would allow sufficient reduction to take place. A calculation method was developed that allows for the prediction of the bed profile and residence time in a rotary kiln.
