Abstract

L'invention est destinée aux centrales thermiques compactes et mobiles, notamment à celles dont la puissance n'excède pas 6 MW. La particularité de ladite méthode est la suivante: Avant d'alimenter une machine à vapeur à entraînement hélicoïdal en vapeur surchauffée, on injecte dans ladite vapeur surchauffé de l'eau dont le débit 'D' est déterminé selon l'équation suivante: D⊃=(i''-i')QΠ/[C(ts-to)+r], dans laquelle i'' et i' représentent l'enthalpie de la vapeur à l'état surchauffé et à l'état saturé, respectivement, sous condition de P-const, kcal/kg; QΠ - débit de vapeur, kg/s; C - capacité thermique de l'eau, kcal/kg °C; r - chaleur de vaporisation; ts- température d'ébullition; to- température de l'eau injectée avant l'injection. Grâce à l'évaporation de l'eau injectée, la vapeur surchauffée retombe à une température à laquelle la vapeur passe à l'état humide.
