In order to recover the wasted energy of the kiln shell heat radiation I am looking for a good idea to install heat collectors around the kiln shell.

A liquid heat carrier should flow through the collectors and transfer the heat to a heat exchanger. From there the heat can be used for radiators in the administration part of the plant, in service rooms, in the lab etc.

In case of using a heat carrier that can be gasified, a turbine can power a generator for power generation.

Who has experience designing an equipment for the a.m. purpose?
