Project examples

Xyloclean project

With an aim to reduce polluting emissions, a smoke filtering device, constructed from components used for decontamination in diesel engines, was tested on a wood-burning stove with staged combustion.

Torrefied wood pellets for the production of heat and electricity

The objective of the C-TOP project is to evaluate the performance of a new type of fuel, prepared with torrefied wood pellets, and to compare several types of pellets for their physico-chemical properties.

Main research areas

Laboratory of Thermal Processes

Training, support, inspection and expertise in industrial heat containment and associated techniques such as combustion, water treatment, compressed air, etc.
The objective is to assist the designer, installer and operator to ensure otimum functioning of the installation, while also garanteeing the efficiency, quality and safety, and in respect for the environment.
