ANALYSIS OF EXERGETIC LOSSES IN A COMBINED HEAT RECOVERY SYSTEM OF A BOILER PLANT

The results of the analysis of exergy losses in the combined heat recovery system of the boiler plant are presented. To study exergy losses in this system, a complex technique has been developed based on the use of exergy analysis methods in combination with methods for representing exergy balances in matrix form. Using a complex technique, exergy losses were calculated in a combined heat recovery system and in its various elements. The relative contribution of each element of the system to the total exergy loss was determined. It has been established that the optimal operating mode of the installation is carried out at the boiler power, which is 50 … 60% of its installed power.
