DryFiciency

Waste Heat Recovery in Industrial Drying Processes

The overall objective of the DryFiciency project is to lead energy-intensive sectors of the European manufacturing industry to high energy efficiency and a reduction of fossil carbon emissions by means of waste heat recovery. Technically and economically viable solutions for upgrading idle waste heat streams to process heat streams at higher temperature levels up to 160 °C are elaborated. The key elements are three high temperature vapour compression heat pumps (two closed loop heat pumps for air drying /one open loop heat pump for steam drying). The solutions are demonstrated and validated under real production conditions in operational industrial drying processes in three leading European manufacturing companies from food, brick and waste management industries. The closed loop heat pumps have been operated for ca. 4000 h each and proved to be efficient measures to reduce energy consumption and carbon emissions.
