Abstract
In an embodiment, a method of modifying an existing gas turbine to create a storage engine is provided. The gas turbine has a combustor, a compressor section, and a turbine section. The method comprises the step of modifying the compressor section of the gas turbine to form the storage engine. Air supplied to the combustor of the storage engine is heated by exhaust of the storage engine and is supplied from a remote source of air. Modifying the compressor section includes removing at least some of a plurality of rotatable airfoils of a compressor of the compressor section and introducing an increased capacity thrust bearing on a shaft line.
Claims6
A method of modifying an existing gas turbine to create a storage engine, the gas turbine having a combustor, a compressor section, and a turbine section, the method comprising modifying the compressor section of the gas turbine to form the storage engine such that air supplied to the combustor of the storage engine is heated by exhaust of the storage engine and is supplied from a remote source of air, where modifying the compressor section includes removing a rotatable airfoil of a compressor and replacing at least one airfoil of a stator of the compressor with a strut.
A method of modifying an existing gas turbine having a combustor, a compressor section, and a turbine section, the method comprising modifying the compressor section of the existing gas turbine to form a storage engine by:
- removing at least one of a plurality of rotatable airfoils of a compressor of the compressor section;
- replacing at least one airfoil of a stator of the compressor with a strut;
- and
- introducing a thrust piston on a shaft line.
