Patent number: 8858161Abstract: An industrial gas turbine engine in which a compressor includes later stage airfoils that are cooled using a coolant from an external closed loop cooling circuit or from a heat recovery steam generator. Cooling air compressed by a compressor external to the IGT engine can be used for cooling of the main compressor airfoils with a heat exchanger to preheat a fuel used in the combustor. Or, water and steam from a heat recover steam generator can be used to cool the compressor airfoils in which steam can be bled off from the steam generator for cooling and then reintroduced into the HRSG at a downstream stage. Steam is used to cool the rotor blades while water is used to cool the stator vanes.Type: GrantFiled: April 7, 2014Date of Patent: October 14, 2014Assignee: Florida Turbine Technologies, Inc.Inventors: John E.

Patent number: 8517684Abstract: A turbine rotor blade with a serpentine flow cooling circuit having three legs in which the first leg and the second leg are upward flowing channels each having a series of slanted ribs that define impingement chambers with impingement cooling holes to provide impingement cooling to the airfoil walls. The second leg is a downward flowing leg that contains no metering holes and is substantially unobstructed to the cooling air flow. The rotation of the blade produces a centrifugal force on the airflow passing through the channels with the metering and impingement holes to aid in the flow towards the blade tip. The return channels are unobstructed in order to minimize the pressure loss on the return channel of the serpentine circuit.Type: GrantFiled: March 14, 2008Date of Patent: August 27, 2013Assignee: Florida Turbine Technologies, Inc.Inventor: John E Ryznic

Patent number: 8240975Abstract: A high compression ratio compressor having multiple stages of airfoils to produce the high pressure rations, where the last stage airfoils are cooled by passing cooling air through the airfoils without discharging film cooling air. The cooling air for the airfoils is bled off from an upstream stage of the compressor, passed through the airfoil to provide for the cooling, and then discharged back into the compressor at a stage upstream of where the bleed off air was extracted and where the pressure is lower. Because of the high pressure rations, the air temperature in the compressor is at such a high temperature that the last stage airfoils must be cooled to prevent thermal damage.Type: GrantFiled: November 10, 2008Date of Patent: August 14, 2012Assignee: Florida Turbine Technologies, Inc.Inventor: John E Ryznic
