Duct Burner

Steam power plants have been extensively used in Iran for a long time, yet no specific step has been taken for promoting their performance. In this regard, full repowering is considered as a way to enhance the performance of steam power plants. Furthermore, because of the continental condition of Iran, duct burners can be used as a common strategy to compensate for power generation shortage caused by environmental conditions. In this study, the effect of using a duct burner on the full repowering of Be?sat Steam Cycle representing both single-and dual-pressure cycles was investigated based on exergy analysis. The results showed that by using the duct burner, due to the increase in the heat recovery steam generator inlet gas temperature, the general thermal efficiency of the combined cycle and the exergy efficiency of the combined cycle and heat recovery steam generator decreased. However, the results revealed an increase in the stack temperature and resulting exergy losses, steam flow and power generation.

Mass Flowrate

Pinch technology has developed for thermodynamic analysis of chemical processes. This technology targets the most possible modification prior to detailed design. Pinch technology it is not sufficient in analyzing systems involving beat and power such as power plants. Exergy analysis, on the other hand, provides a powerful tool for heat and power analysis, although at times it does not provide clear practical design guideline. To prevailing over the weaknesses of both analysis, in obtaining a practical design guideline for the analysis of heat and power systems, combined pinch and exergy analysis (CPEA) is developed. This paper introduces the application of CPEA to advanced steam power plant. The paper presents a new methodology in optimization of steam extractions mass flowrate from multiple pressure levels of steam turbine with using CPEA. Efficiency improvement about 0.34% can be obtained by application of new approach and likewise, hot and cold utilities of cycle can be decreased.
