PROBLEM TO BE SOLVED: To provide improved gas turbine cooling systems so as to realize adequate cooling even during extreme turndown operations without a loss of overall efficiency, a decrease in a component lifetime, or an increase in undesirable emissions.SOLUTION: The present application provides a gas turbine engine for low turndown operations. The gas turbine engine may include a compressor associated with a compressor bleed air flow, an ambient air source associated with an ambient air flow, a turbine, and an eductor. The eductor blends the compressor bleed air flow and the ambient air flow into a blended air flow for use in cooling the turbine. |
