Study / Heat recovery from industrial steam

In France, the amount of heat loss in industrial processes is estimated at 109.5 TWh, wich is equivalent to 36% of the fuel consumption of the industry. Among these losses, 52,9 TWh are exhausted at temperatures exceeding 100°C. Half of the "heat deposit" is produced by agri-food and chemistry industries. Moreover, steams from dryers and fumes from furnaces represent respectively 30% and 38% of available exhausts.

This study targets these two industrial sectors in order to identify the constraints and technologies available to recover the heat carried by industrial steams and fumes. It also aims at highlighting opportunities for new heat recovery projects in the future.
