Energy concepts for kiln and dryer

In cooperation with Hochschule Osnabrück – University of Applied Sciences – and within the scope of a bachelor thesis by Roman Flatau, Keller HCW has devised a system for using excess kiln air to generate electricity via a steam process. At the same time, the dryer‘s gas consumption can be markedly reduced by exploiting the resultant energy of condensation.

Based on comprehensive measurements, a cooling-zone energy balance was compiled for a tunnel kiln at a roof tile factory. The data yield enabled development of a process in precise alignment with the plant‘s own specific parameters. The...
