  System composing of two high pressure heaters (HPH1 and HPH2), one deaerator-feed water tank (DEA) and four low pressure heaters (LPH4, LPH5, LPH6 and LPH7). This study aims to conduct a performance evaluation during full load on each unit’s regenerative feed water heaters, both closed and open type, using ASME PTC 12.1 and an analysis on the heater off design condition at 5% load intervals. Off design conditions on a heater occurred on several occasions, where unit is at low load or derating, and may affect overall efficiency of a plant. The parameters needed such as load, extraction steam pressure, heater drain temperature and inlet and outlet feed water temperature on a heater were collected on the Distributed Control System (DCS) at Central Control Room (CCR) station. Other necessary data like steam and drain enthalpies were collected using CATT 3 software or steam tables. Ther.. View More»
