Abstract
A turbine engine assembly is provided. The assembly includes a compressor, and an air duct coupled in flow communication with the compressor. The air duct is configured to channel a flow of bleed air from the compressor therethrough. The assembly also includes a fluid supply system coupled in flow communication with the air duct, wherein the fluid supply system is configured to channel a flow of fluid towards the air duct to modify a temperature of the bleed air based on an operating condition of the turbine engine assembly.
Claims20
A turbine engine assembly comprising:
- a compressor;
- an air duct coupled in flow communication with said compressor, said air duct configured to channel a flow of bleed air from said compressor therethrough;
- and
- a fluid supply system coupled in flow communication with said air duct, wherein said fluid supply system comprises:
- a control valve in upstream flow communication with said air duct;
- a water line coupled in upstream flow communication with said control valve and configured to channel a flow of water towards said control valve;
- a steam line coupled in upstream flow communication with said control valve and configured to channel a flow of steam toward said control valve;
- and
- a controller operably coupled to said control valve, said controller operable to selectively channel the flow of water and the flow of steam downstream from said control valve as a flow of fluid towards said air duct to selectively (i) reduce a temperature of the flow of bleed air in said air duct during a steady state operating condition of the turbine engine assembly, and (ii) increase a temperature of the flow of bleed air in said air duct during a transient operating condition of the turbine engine assembly.
A system for use in cooling modifying a temperature of compressor bleed air in a turbine engine assembly comprising a compressor, said system comprising:
- an air duct coupled in flow communication with the compressor, said air duct configured to channel the compressor bleed air from the compressor therethrough;
- and
- a fluid supply system coupled in flow communication with said air duct, wherein said fluid supply system comprises:
- a control valve in upstream flow communication with said air duct;
- a water line coupled in upstream flow communication with said control valve and configured to channel a flow of fluid water towards said air duct control valve;
- a steam line coupled in upstream flow communication with said control valve and configured to channel a flow of steam toward said control valve;
- and
- a controller operably coupled to said control valve, said controller operable to selectively channel the flow of water and the flow of steam downstream from said control valve as a flow of fluid towards said air duct to selectively (i) reduce a temperature of the compressor bleed air in said air duct during a steady state operating condition of the turbine engine assembly, and (ii) increase a temperature of the compressor bleed air in said air duct during a transient operating condition of the turbine engine assembly.
A method of operating a turbine engine assembly, said method comprising:
- channeling a flow of bleed air from a compressor of the turbine engine assembly into an air duct;
- channeling a flow of water into a water line coupled in upstream flow communication with a control valve;
- channeling a flow of steam into a steam line coupled in upstream flow communication with the control valve;
- and
- selectively channeling the flow of water and the flow of steam downstream from the control valve as a flow of fluid towards the air duct such that a temperature of the flow of bleed air in the air duct is selectively (i) reduced during a steady state operating condition of the turbine engine assembly and (ii) increased during a transient operating condition of the turbine engine assembly.
