Methods of Modifying Existing Gas Turbine Engine Design to Create a Combined Storage Engine and Simple Cycle Peaker Product

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 and a cooling air supply for later stages in the turbine section is supplied from air that is from the remote source and is heated by the exhaust of the storage engine to a temperature lower than the temperature of air being introduced into the combustor of the storage engine.

A method of modifying an existing gas turbine to create a storage engine, the storage engine having at least a substantially unmodified gas turbine combustor and turbine section and a modified compressor section 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 and the cooling air supply for later stages in the turbine section is supplied from air that is from the remote source and heated by the exhaust of the storage engine to the same temperature as the temperature of the air being introduced into the combustor of the storage engine, but then blended with cooler air from the remote source to form a supply of cooling air the later stages of the turbine section that is cooler than the air entering the storage engine's combustion section.

A method comprising modifying an existing gas turbine to create a storage engine, the storage engine having a substantially unmodified gas turbine combustor and turbine section and a modified compressor section such that air supplied to the combustor of the storage engine is heated by exhaust of the storage engine and is supplied from a combination of stored air in a tank and a fueled engine driven compressor such that when the storage engine is not in operation, the fueled engine driven compressor can be run independently of the storage engine and be used to pre-heat the storage engine to reduce start up time.

A method comprising modifying an existing gas turbine to create a storage engine, the storage engine having a substantially unmodified gas turbine combustor and turbine section and a modified compressor section such that air supplied to the combustor of the storage engine is heated by exhaust of the storage engine and is supplied from a combination of stored air in a tank and electric driven compressors and fuel driven compressors such that the fueled engine driven compressor can be run independently of the storage engine to generate power.

A method comprising modifying an existing gas turbine to create a storage engine, the storage engine having a substantially unmodified gas turbine combustor and turbine section and a modified compressor section such that air supplied to the combustor of the storage engine is heated by exhaust of the storage engine and is supplied from a combination of stored air in a tank and real time running low pressure compressors, the method further comprising injecting water generated during an intercooling processor of the compressor into the storage engine when the storage engine is operational to generate additional power from the storage engine.
