European researchers aim to recover more than 40% of waste heat streams in energy intensive industries. Will the simple technology of heat pipes be a cost effective and efficient way to receive this aim?

Heat Pipe Technologies for Industrial Applications

Ten companies and institutes from across Europe have joined forces to improve the energy performance of energy intensive processes. Their solution is based on heat exchanger technology (HPHE) using heat pipes for thermal recovery. As part of the project, three HPHE prototypes will be built and tested for three different production plants in the aluminium, steel and ceramics sectors. The different industrial environments produce different exhaust streams with different waste heat quantity and quality (chemical composition, different particles coming out along with the gases, temperature and pressure of the flue gases, …), and provide different processes where the recovered heat might be utilized. The challenge: the recovery solution should be adapted increasing the overall efficiency and being cost-effective.
