CALCINATION OF COKE

摘要

SPECIFICATION A method and apparatus in a rotary kiln in which the heat for initially raising the temperature of the coke to evolve moisture and volatile gases from the coke and to ignite the volatile gases is supplied by a burner located at the upper end of the rotary kiln at which the coke is introduced into the kiln and in which the temperature of the coke is controlled downstream of the burner to continue evolving volatile gases without substantial loss of carbon due to burning by the introduction of air into the kiln and in which the volatile gases and the gases of combustion are discharged at the lower end of the rotary kiln and the calcined coke is separated from the gases.
