Unlocking Waste Heat Potentials in Manufacturing

Industry releases vast amounts of heat energy as dissipative waste heat to the atmosphere. It is therefore necessary to acquire a better understanding of the waste heat potentials in manufacturing. The paper presents an integrated approach for identifying and quantifying waste heat potentials of different production processes. The identification is based on an estimation procedure followed by a simulative assessment of production processes to quantify and allocate waste heat over time. The approach further elaborates on a potential source and demand matching of heat streams. A case study from the automotive industry demonstrates the applicability of the approach.
