energy of the in- and outgoing streams is accounted for. To calculate the heat energy of the different streams, polynomials were used to describe the temperature dependent heat capacities of the different components. The polynomials were fitted to thermodynamic data from the literature. Examples on how the heat rate of the kiln
that contribute to mass transfer in rotary kilns, and their relation to each other. In this respect, this work is also applicable to heat transfer in rotary kilns, where analogous dimensionless numbers can be identified. Another important contribution is the recognition of the important contribution of the passive layer in mass transfer.
