Abstract
The present invention is a combustion turbine assembly connected to a steam generator which utilizes deaerated potable water. The steam formed by the steam generator may be combined with air and injected into the combustor of the combustion turbine assembly to increase the mass flow of gas through the turbine for power augmentation. The deaeration of the feed water to the steam generator eliminates the need to demineralize the water and eliminates the use of more costly alloys for heat exchanger components of a steam generator.
Claims24
A system for generating steam for a combustion turbine comprising:
- a deaerated water source connected to a partial boiler wherein at the partial boiler partially evaporates deaerated water creating a steam-liquid mixture;
- a separator vessel connected to the partial boiler wherein the separator vessel separates the steam-liquid mixture into a steam component and a liquid component;
- and
- a superheater connected to the separator vessel wherein the superheater heats the steam component to a desired temperature and delivers the heated steam component to a combustion turbine connected to the superheater.
A combustion turbine system for generating electric power comprising:
- a deaerated water source connected to a partial boiler wherein the partial boiler partially evaporates liquid received from the deaerated water source creating a steam-liquid mixture;
- a separator vessel connected to the partial boiler wherein the separator vessel separates the steam-liquid mixture into a steam component and a liquid component;
- a superheater connected to the separator vessel wherein the supercharger heats the steam component to a desired temperature;
- a combustor connected to the superheater to receive the heated steam component connected to a turbine and a compressor;
- a fuel source connected to the combustor;
- a gas source connected to the compressor;
- and
- an electric generator connected to the compressor.
A method for generating steam for use in a combustion turbine comprising:
- partially evaporating deaerated water to create a steam-liquid mixture;
- separating the steam-liquid mixture into a steam component and a liquid component;
- superheating the steam component;
- and
- delivering the superheated steam component to a combustion turbine.
