Abstract
Based on the design of boilers in the most optimal operating mode, the percentage of energy losses, has a strong impact on the efficiency of these equipment. By identifying the sources of energy losses and finding solutions to reduce fuel consumption and save energy, an important step can be taken to improve the efficiency of boilers. In this research, the thermal performance and operational efficiency of the boilers of the Isfahan refinery are studied. The ASME PTC4 is the reference code for boiler performance testing, which accurately determines the performance of boilers based on their technical and operating specifications. The sources of heat losses in the boiler assembly are identified and significant losses are specifically investigated to propose the solution. To reduce the remarkable losses and increase the boiler efficiency, installing an economizer to use the heat available in the boiler stack to heat the boiler inlet water, is recommended.
