배열회수보일러 급수예열기 추가 설치에 따른 열효율 해석

초록

KOWEPO do the installation to add feedwater preheater in running power plants in order to supply hot water for district heating enterprise .However, in the summer season, Gas turbine consistently run for generating power. so it cause a problem to promote deterioration and fall utilization rate at feed water heater as it receives heat road by exhaust gas. KOWEP improved for #7,8 to utilize as a addition heating surface at HRSG’s low pressure part. This research studied heat efficiency performance analysis of HRSG in the cases of additional installation of feed water preheater by utilize additional heat surface or not. The efficiency of HRSG increase for all units, furthermore It get higher 2.6%p.
