The aim of this research was to propose new system solutions for utilization of industrial waste heat, evaluate their performance under various operating conditions, and eventually recommend them for further, more detailed applicability investigation. Conventional waste-heat utilization systems are based on the Rankine cycle and characterized by relatively low turbine inlet temperature. In comparison with such systems, significant increases in electric efficiency and output can be expected by introducing methaneoxygen combustion for direct heating of the working medium. Three system configurations were considered, combining low-quality (industrial waste heat) and high-quality (methaneoxygen combustion) heat sources. In two of the configurations investigated, heat transfer from the working to the feeding medium provided heat recirculation. The performance of the proposed systems with various contributions of the two sources to the total heat supply was investigated. Special attention was paid to the combination effect. This is understood as obtaining an output higher thau that obtained with the same sources being separated. The simulation results confirm that two of the systems investigated can provide significant merits under reasonable conditions. They also prove that heat recirculation is indispensable to achieve such performance. The combination effect is obtained with a moderate or manageable turbine inlet temperature. Possible reduction of the system size and cost is another advantage of the combination. The general conclusion is that two of the proposed system solutions are very promising and are recommended for further applicability investigation.
