As in a rotary dryer, typical bed loading in kilns is about 10%. As one might expect, the direct-fired rotary dryer acting as a dispersion device can achieve higher heat transfer rates than refractory lined kilns. The result is that the rotary dryer can transfer more heat per unit volume than a rotary kiln. Indirect Rotary Dryers & Rotary Kilns
lime recovery kilns. The energy content of these "fuels" varies considerably, but each makes a contribution to overall heat input. These materials contain some sulfur that can derate the kiln capacity, and all of them lower the heat rate of the kiln. Tall oil has been used to fire lime kilns where its value as a mill product is low.
