WASTE HEAT UTILISATION FROM THE PROCESS OF BURNING THE CEMENT CLINKER IN THE POWER STATION WITH SUPERCRITICAL ORGANIC CYCLE

At the work analysis of the possibility and profitability of supplying the power station with the supercritical, organic power plant supplied by waste energy from the process of producing the cement clinker have been conducted. This process is characterized relatively high energy consumption, particularly beneficial parameters has excess air from process of cooling the clinker. As part of this work a possibility of converting the waste heat with temperature 270 degrees C was analysed to the electricity production using the supercritical organic cycle so-called S-ORC. For four chosen organic working substances: R 41, R 152a, R245fa and R356 mfc were carried out calculation of characteristic parameters: the efficiency and the specific work. Also a simplified economic analysis of applying the S-ORC in the cement industry was conducted based on indicators of the economic appraisal: net present value (NPV) and index of the profitability (PI).
