A gas turbine engine has in flow series: a compressor section, a combustor, and a turbine section. The engine further has a steam generator, and a water and steam delivery system. During an engine start-up period, the delivery system delivers liquid water to the combustor and mixes the delivered water in its liquid state with working gas in the combustor. After the start-up period, the delivery system accepts steam from the steam generator, delivers the steam to the combustor and mixes the delivered steam in its gaseous state with the working gas in the combustor.

Gas turbine engine with water and steam injection

A gas turbine engine has in flow series: a compressor section, a combustion chamber, and a turbine section. The engine further has a steam generator. The combustion chamber has a steam reservoir located at the upstream end thereof. The steam reservoir receives steam from the steam generator, and delivers the received steam into a combustion zone of the combustion chamber.

Steam injected gas turbine engine

An aerofoil assembly including an aerofoil and a spray element that supplies fluid to a gas turbine engine. The aerofoil has a first part with a leading edge when located in the gas turbine engine, and a second part with a trailing edge when located in the gas turbine engine. The first part has features that slide relative to and engage with complementary features of the second part to form a releasable arrangement.

Components for a gas turbine engine

In order to allow dual fuel operation, that is to say gas and liquid fuel, a fuel injection arrangement and an assembly are provided in which an injection conduit provides constriction to an airflow towards an outlet. In an assembly a plurality of arrangements including liquid fuel jets are arranged to such that through high angle incidents by the airflow appropriate vaporization and droplet formation is achieved for a fuel/air mixture combustible in a combustor of a turbine engine. At low liquid fuel flow rates below a pre-determined level the liquid fuel is atomised and entrained by the airflow. At high liquid fuel flow rates the fuel splash impinges upon a wash surface to develop a wash film which is again vaporised and atomised about an edge for a fuel/air mixture capable of combustion.

Fuel injection

A joint for a gas turbine fuel injector, the joint comprises a housing for supporting a fuel injector, a first tube terminating within the housing and a second tube. The housing at least partially encloses an adaptor having a bore, with one end of the first tube and one end of the second tube being located within opposing ends of the bore. First sealing means are provided between the outside of the first tube and the adaptor bore, second sealing means are provided between the outside of the second tube and the adaptor bore and third sealing means are provided between the outside of the adaptor and the housing. The joint is particularly suitable for conduits carrying a relatively cold fluid mounted in a relatively hot housing.
