Embodiment Construction

[0030] figure 1 A turbine plant 1 is shown comprising a gas turbine section 2 and a steam turbine section 4 , wherein the gas turbine section 2 and the steam turbine section 4 are arranged concentrically. This principle is disclosed in Swedish Patent No. SE530142 C2, US Provisional Application No. 60 / 969997 and PCT Application No. PCT / SE2008 / 050258.

[0031] Combustion gases enter (indicated by arrow 3 ) the gas turbine section 2 of the turbine plant 1 from the combustion chamber. exist figure 1 , the combustion gases pass through the gas turbine section 2 from left to right (as indicated by arrows 3 and 5 ), so that the gases drive the turbine shaft 6 by acting on a plurality of gas turbine rotor blades 7 . The gas turbine section 2 also includes a plurality of guide vanes or gas turbine stator blades 9 . The rotor blades 7 and the stator blades 9 are arranged at intervals along the longitudinal axis 11 of the turbine.

[0032] Fluid channels 13 are provided in the gas tu...

Abstract

The invention relates to a method for conversion of a gas turbine engine (37) to a turbine engine with a combined gas and steam turbine device (33). The invention also relates to improvements of a turbine device (1) comprising concentrically arranged gas and steam turbine portions (2, 4), especially with regards to the turbine blades (7, 17, 9, 19). Further, a method for regulating a turbine engine comprising such a turbine device is proposed.

Description

technical field [0001] The present invention relates to improvements in turbine installations comprising concentrically arranged gas turbine sections and steam turbine sections. The invention also relates to a method for regulating a turbine engine comprising such a turbine device. Background technique [0002] Gas turbine engines are used in many applications to convert the chemical energy of a fuel into mechanical energy. Among them, the gas turbine is driven by the air flow generated by the combustion of fuel. A gas turbine typically drives a compressor to compress air and provide an additional amount of oxygen to the combustor. [0003] In general, the advantage of a gas turbine engine is the engine's ability to deliver high power at low weight. The disadvantage is usually low efficiency (i.e. utilization of the chemical energy of the fuel). [0004] High efficiency turbine plants comprising concentric gas and steam turbine sections are disclosed in Swedish Patent No...
