Patent number: 7549834Abstract: An actuation pressure control system effects actuation of adjustable seal segments between stationary and rotating turbomachinery members. At least one actuator is coupled with each of the adjustable seal segments and controls a position of the seal segments, respectively. A pressure system is disposed within the turbomachinery that measures or estimates ambient pressure representing an actuator back pressure acting against the actuator. A pressure regulator via a controller pressurizes the actuator to a level sufficient for a desired seal operation and controls actuator pressure based on the actuator back pressure.Type: GrantFiled: June 19, 2006Date of Patent: June 23, 2009Assignee: General Electric CompanyInventors: Darrin Glen Kirchhof, William Charles Below, Mark Edward Burnett, Frederick George Baily, Shorya Awtar, Norman Arnold Turnquist

Patent number: 6951339Abstract: A brush seal is provided between static components of a turbine. The turbine flowpath has an inlet spaced from another the inner web of the first stage nozzle. A brush seal is disposed between the two static components to minimize leakage flow to the packing casing region. The bristles of the brush seal are preloaded to fill any gap between the static components caused by distortion or out-of-roundness of the opposed surfaces being sealed. A side plate may contact the opposed sealing surface, increasing the pressure capability of the brush seal and minimizing overall seal leakage by providing the minimum possible flow area restricted solely by the bristles.Type: GrantFiled: August 26, 2004Date of Patent: October 4, 2005Assignee: General Electric CompanyInventors: Norman Arnold Turnquist, Mark Edward Burnett, Huseyin Kizil, Kamlesh Mundra
