COMPARATIVE ANALYSIS OF POSSIBILITIES FOR RAISING THE EFFICIENCY IN THERMAL POWER PLANT BY UTILISATION OF WASTE HEAT ENERGY

ABSTRACT
The possibility to use flue gases waste heat for increasing the efficiency of thermal power plant (TPP) explained in this work refers to lignite fired TPP-Bitola in Macedonia (3x233 MW installed electric capacity). Possibility to utilize low-temperature heat energy at the plant’s cold end is also considered in the analysis. Specific fuel consumption is used as an analysis and comparison parameter. Its reduction, compared to the basic power unit ranges between 0.4% and 3.4%. An analysis presenting economic feasibility of the low-temperature heat energy utilization concept for two different refrigerants used in the heat pump is also presented.
