Abstract

｢定常排出量」に「過渡補正値」を乗じてＳｏｏｔ排出量が算出される。定常排出量は定常運転状態でのＳｏｏｔ排出量であり、テーブル検索で取得される。Ｓｏｏｔ排出量に影響を与える複数の因子の各々について、因子の値に対するＳｏｏｔ排出量に関する特性式に因子の定常値（テーブル検索値）及び過渡値（現在値）を代入して定常特性値及び過渡特性値がそれぞれ取得され、「定常特性値と過渡特性値との比」が算出される。過渡補正値は、各因子についての「定常特性値と過渡特性値との比」を全て乗じて得られ、過渡運転状態での各因子についての「過渡値の定常値からのずれ」の影響が全て考慮された「Ｓｏｏｔ排出量の定常排出量からのずれの程度を表す係数」に算出される。
