The article considers the issue of thermodynamic optimization of heat power equipment. The solution to this problem allows one to increase the energy efficiency of heat systems by reducing the energy resources consumption. The article compares the traditional (enthalpy) pinch method and the exergy pinch method. The exergy method of thermodynamic analysis allows one to take into account both quantitative and qualitative characteristics of thermal processes. A furnace that heats oil in the ELOU AT-6 primary oil refining unit was selected as an object of the study. The results obtained using the traditional pinch method showed that the furnace does not require optimization. However, the exergy analysis showed that the furnace has exergy losses. The method of exergy pinch analysis allows us to formulate and justify specific design measures aimed at increasing the furnace energy efficiency. Using the exergy pinch analysis, one can identify the unused exergy and determine the part in which the loss occurs.
