Abstract
A single wheel radial flow gas turbine having a single rotating wheel and a stationary shroud. The wheel has a radial flow compressor section at its inner portion and a turbine section at its outer portion. The compressor and turbine sections are located on the same side of the wheel, which is directly or indirectly coupled to a generator for absorbing the excess rotational energy. A radial flow combustor section and a nozzle section are mounted on the stationary shroud. Air flows radially through the compressor, combustor, nozzle, and turbine sections; there is essentially no axial flow component. Optionally, water may be injected radially downstream from the fuel injectors for power augmentation, NOx reduction, and metal temperature moderation.
Claims16
A radial flow gas turbine comprising:
- a rotatable wheel having an interior side;
- a centrifugal compressor section disposed on said interior side of said wheel;
- wherein the compressor section comprises a spoked pattern of fins, each fin being a continuous raised fin extending alone a radius of the rotatable wheel, such that a substantially linear and uninterrupted channel is formed between each successive fin;
- a radial outward flow turbine section disposed on said interior side of said wheel, said turbine section being located radially outward from said compressor section;
- and
- a stationary shroud having a combustor section and a nozzle section disposed radially between said compressor section and said turbine section.
A radial flow gas turbine consisting essentially of:
- a single, rotatable wheel having an interior side;
- a centrifugal compressor section disposed on said interior side of said wheel;
- wherein the compressor section comprises a spoked pattern of primary fins, each primary fin extending in a continuous direction alone a radius of the rotatable wheel such that the primary fins form a single concentric row;
- a radial outward flow turbine section disposed on said interior side of said wheel, said turbine section being located radially outward from said compressor section;
- and
- a stationary shroud having a radial flow combustor section and a nozzle section disposed radially between said compressor section and said turbine section.
