References(13) Cited-By(1) Gas-solid contact efficiency of a transversely aerated rotary kiln incinerator has proven to be very high. The paper addresses an experimental method to obtain heat and mass transfer coefficients between gas and solid particles in the transverse bed of an aerated rotary kiln incinerator. It is found that the transfer coefficients are sensitive to aeration rate but not to rotation speed. Equations, which correlate the transfer coefficients and relative parameters, are proposed in terms of dimensionless groups to estimate the heat and mass transfer rate in the transverse bed of an aerated rotary kiln incinerator. Furthermore, the temperature distribution in the transverse bed of such a rotary kiln is considered reasonably uniform, which is caused by well distributed inlet gas and solid mixing due to rotation.
