Design Basis. The steam jet air ejectors shall be sized based on system requirements, but shall always meet or exceed the recommendations of the Heat Exchanger Institute standards for steam surface condensers. Modes of Operation The condenser air removal system shall have two operating modes: "hogging" and "holding". Hogging operation shall utilize the hogging ejector for plant startup where large quantities of air and noncondensable gases are removed from the condenser before the startup of the steam turbine. Holding involves normal operation where noncondensable gases are continuously removed from the system at low condenser pressure. -------------------------------------------------------------------------------- Proprietary Information Page 13 AES IRONWOOD CONTRACT FINAL ISSUE - OCTOBER 30, 1998 --------------------------------------------------------------------------------
