Title
(EN) TURBINE PROTECTION SYSTEM
(FR) SYSTÈME DE PROTECTION DE TURBINE
Abstract
(EN)
In a system and method for a turbine protection system having a three-way valve, working fluid is heated by boiler to form saturated steam. Saturated steam is heated by superheater to change into a dry steam. Superheater may at least in-part be heated by exhaust gases from an internal combustion engine. Control module may receive information indicating, or for determining, at least one property of the working fluid that's exiting the superheater and/or entering into the three-way valve. If the working fluid is dry steam that is within a predetermined temperature and/or pressure range, three-way-valve may be positioned so that the working fluid exits a turbine side outlet of the three-way valve and flows to a turbine. Otherwise, three-way-valve may be positioned for the working fluid to by-pass the turbine, and instead flow into the pressure reducer valve.

L'invention concerne un système et un procédé pour un système de protection de turbine ayant une soupape à trois voies, un fluide de travail étant chauffé par une chaudière pour former de la vapeur saturée. La vapeur saturée est chauffée par un surchauffeur à des fins de transformation en vapeur sèche. Le surchauffeur peut être chauffé au moins en partie par des gaz d'échappement provenant d'un moteur à combustion interne. Un module de commande peut recevoir des informations indiquant, ou servant à déterminer, au moins une propriété du fluide de travail qui sort du surchauffeur et/ou entre dans la soupape à trois voies. Si le fluide de travail est de la vapeur sèche se trouvant dans les limites d'une plage prédéterminée de température et/ou de pression, la soupape à trois voies peut être positionnée de sorte que le fluide de travail sorte au niveau d'une sortie côté turbine de la soupape à trois voies et s'écoule jusqu'à une turbine. Sinon, la soupape à trois voies peut être positionnée pour que le fluide de travail contourne la turbine, et s'écoule à la place dans le détendeur.
