ENERGY AND ENVIRONMENTAL ASPECTS OF INDUSTRIAL HEAT SAVING IN VARIOUS SITUATIONS
Large industrial facilities and industrial clusters traditionally operate a combined heat and power unit serving as marginal heat source. This unit can consist of either a steam Rankine cycle unit or comprise a Combined Cycle-based cogeneration unit. These distinctive designs differ by both heat to power ratio and delivered heat quality (temperature); both parameters being further impacted by the unit´s operation. A change in heat quantity exported from the combined heat and power unit can thus have various impact on cogenerated electric energy quantity and released greenhouse gases emissions. This contribution aims at elucidating this aspect of industrial heat saving projects with the goal to deliver valuable input for industrial energy managers and decision makers. Rankine and combined cycle units are modeled, providing a realistic assessment of energetic and environmental impact variability of their operation change due to the variable heat export. ; This work was financially supported by the Slovak Research and Development Agency, Grant No. APVV-15-0148 and APVV-18-0134 as well as by the Faculty of Chemical and Food Technology, Slovak University of Technology in Bratislava.
