대기온도 변화에 따른 150 MW 화력발전소용 공랭식 복수기 송풍기의 운전수량 선정

초록

During this study, number of fan by ambient air temperature that condenser pressure satisfies steam turbine exhaust pressure condition with intervals of 3℃ within the 150 MW thermal power plant site temperature range of -17.1℃ to 36.7℃ was reviewed. An air cooled condenser changes its operating pressure influenced by cooling air circulation amount by atmospheric temperature and number of fan. For stable power plant operation, these were confirmed to maximize a quantity of air-cooled condenser fans at above or equal from design ambient temperature and to reduce an amount of circulating air to an air cooled condenser by depending on a quantity of fan considering exhaust pressure operation condition of a steam turbine at below design ambient temperature.
