Air Cooled Condenser Sample Clauses
Air Cooled Condenser. An air-cooled condenser will be connected via a carbon steel exhaust duct to the steam turbine exhaust flange to condense the exhaust steam. The condenser will be equipped with a hogging ejector, and one (1) 100% two-stage twin steam jet air ejector system. During startup motive steam for SJAE, hogging ejector, and STG gland steam will be provided via steam letdown from the HP steam system. The condenser will be complete with a rupture disc pressure-relieving device. Windwalls made of ribbed galvanized steel sheeting will be provided to prevent air recirculation and alleviate excessive noise.
Air Cooled Condenser. The ACC fans will be controlled by the DCS. The fan speed and the number of fans in service will be determined by the control system based on the turbine exhaust temperature and pressure, condensate temperature, ambient temperature, relative humidity, and the Facility mode of operation (Steam Turbine in service or Steam Turbine on bypass). The hogging ejector and two-stage twin steam jet air ejector systems will be DCS controlled and monitored.
Air Cooled Condenser. The condenser is an induced draft, air-cooled heat exchanger. The tubes are arranged in a one-pass configuration where motive fluid vapor is fed from the inlet EPC SHEDULE B September 23 2003 Wairakei EPC -------------------------------------------------------------------------------- box to the tubes. The motive fluid is cooled and condensed, inside the tubes, by forced air flowing outside of the finned tubes in a cross-flow pattern. The condensed motive fluid accumulates in the hot well collector from where it flows by gravity to the motive fluid filters and pumps. The condenser tubes are made of carbon steel tubes with aluminum fins.

Circuit for leaks f) Check high pressure cut-out g) Check and calibrate low-ambient controls h) Record air temperature in/out i) Record motor amps
