Abstract

Ujawniono systemy oraz urządzenia do aktywnego sterowania cieplnego części składowych turbiny. W jednym przykładzie wykonania system sterowania cieplnego turbiny zawiera: źródło ciepła (122) ukształtowane, aby łączyć się z turbiną; zestaw czujników usytuowanych wokół turbiny oraz przystosowanych do uzyskiwania danych operacyjnych z turbiny; oraz urządzenie liczące (510), połączone komunikacyjnie ze źródłem ciepła oraz z zestawem czujników, przy czym urządzenie liczące jest skonfigurowane do regulowania wsadu cieplnego ze źródła ciepła do turbiny, na podstawie danych operacyjnych uzyskiwanych przez zestaw czujników.
