Abstract
ABSTRACTIn this research paper, work is done on a 120 MW coal-fired thermal power plant. Power plants are used for power generation, but during the process, some amount of steam is extracted from steam turbines to increase the feed water temperature, and steam extraction changes power generation/output from the power plant. The power generation also depends upon the pressure drop in the extraction lines/pipes. So, different case studies have been done for all feed water heaters. Then the power generation and the heat rate have been found for different extraction line pressure drops. These case studies indicate that if the extraction line pressure drop varies, then the power output and the heat rate also vary. The correction factor curves for power and heat rate have also been generated for the combined effect of extraction line pressure drop. Thus, the performance of the plant has been evaluated.
