Title
(EN) TURBINE SYSTEM
(FR) SYSTÈME DE TURBINES
Abstract
(EN)
A steam turbine system is described comprising at least one high pressure turbine, and / or at least one intermediate pressure turbine, and at least one first low pressure turbine, mounted on a first rotary shaft that is coupled to drive at least one first electrical generator; and at least one further low pressure turbine, mounted on a further rotary shaft that is coupled to drive at least one further electrical generator. The same rotary generator on the further shaft may be connected by flexible couplings to at least two or more low pressure turbines for multiple units within the same power plant. There is a steam supply system to supply low pressure steam to the low pressure turbines provided with a steam outlet to enable extraction of auxiliary process steam from a location in the steam supply system upstream of the further low pressure turbine but not upstream of the first low pressure turbine. The system is described as part of a steam generator fuelled by carbonaceous fuel combustion with post combustion carbon capture capability.

L'invention porte sur un système de turbines à vapeur comprenant au moins une turbine à haute pression et/ou au moins une turbine à pression intermédiaire, et au moins une première turbine à basse pression, lesquelles sont montées sur un premier arbre rotatif qui est accouplé pour entraîner au moins un premier générateur électrique; et au moins une autre turbine à basse pression montée sur un autre arbre rotatif qui est accouplé pour entraîner au moins un autre générateur électrique. Le même générateur rotatif monté sur l'autre arbre peut être relié par des accouplements flexibles à au moins deux ou plus de deux turbines à basse pression pour des unités multiples dans la même centrale. Est prévu un système d'alimentation en vapeur servant à alimenter en vapeur à basse pression les turbines à basse pression, qui est équipé d'une sortie de vapeur pour permettre d'extraire de la vapeur de traitement auxiliaire d'un point du système d'alimentation en vapeur situé en amont de l'autre turbine à basse pression mais non pas en amont de la première turbine à basse pression. Le système est décrit sous la forme d'une partie d'un générateur de vapeur activé par la combustion d'un combustible carboné qui possède une capacité de capture du carbone après la combustion.
