live steam 新汽〔直接從鍋爐出來的高壓蒸汽,與“廢氣”相對而言〕。

live steam valve

Presents the steady - state programming with constant coolant average temperature and constant live steam pressure , an ideal programming for marine nuclear power plant ( npp ) , under which , both the coolant average temperature and the live steam pressure of nuclear steam supply system ( nsss ) are constant when the steady state operating condition is varied , and points out that in comparison with the steadysate programming with constant coolant average temperature , the ideal programming can improve the overall operating performance of npp effectively , especially in low - load range , for instance , raise the heat efficiency of npp , decrease the operating noise of main coolant pump , and improve the conditions of design , operation and control of the secondary loop system 雙恒定運行方案是船用壓水堆核動力裝置的理想運行方案.在這種運行方案下,當裝置穩態功率變化時,冷卻劑平均溫度與蒸汽壓都保持不變,與通常采用的冷卻劑平均溫度恒定運行方案相比,有效地改善了核動力裝置的總體運行性能,特別是在低負荷運行時,可以提高裝置經濟性、降低主泵運行噪聲、改善二回路系統的設計、運行和控制條件,這對于提高船用核動力裝置的運行可靠性和安全性具有實際意義
