摘要： A method for assembling at least one seal assembly to a turbine having a casing extending at least partially around a rotor is provided. The method includes coupling the seal assembly to the casing such that the seal assembly extends into a fluid flow passage defined between the rotor and the casing and coupling at least one spring between the seal assembly and the casing to bias each seal assembly.

摘要： A cooling path is defined through a double-flow steam turbine. The steam turbine includes a generator end and a turbine end and a double-flow tub diaphragm disposed axially between the generator end and the turbine end. A first stage of the steam turbine includes a plurality of first stage nozzles and a plurality of first stage buckets, and a steam path is defined from an inlet region, through the turbine end, to a steam outlet. The cooling path includes cooling holes in the tub diaphragm and root radial seals permitting steam flow beneath the tub diaphragm and around the first stage nozzles and back into the steam path before the first stage buckets.

摘要： A method of cooling a double flow steam turbine includes supplying steam flow to each nozzle of the sections of the turbine; reversing a portion of each steam flow to provide a reverse steam flow from an aft side to a forward side of each section. Each reverse steam flow is directed to an annular space between a rotor and a tub. The method further includes removing the reverse steam flows through a pipe, the pipe having a first end at the annular space at a first pressure and a second end at a second pressure that is lower than the first pressure. A double flow steam turbine, includes a pair of nozzles, each nozzle being provided at a section of the turbine; a rotor supporting buckets of the sections; a tub supporting the pair of nozzles; and a pipe extending from an annular space between the tub and the rotor. The pipe has a first end at the annular space and second end. A pressure at the first end of the pipe is greater than a pressure at the second end.

摘要： A steam turbine includes a turbine rotor, a generator end having a generator end first stage with a first reaction, and a turbine end having a turbine end first stage with a second reaction not equal to the first reaction. The steam turbine includes a tub section disposed between the generator end and the turbine end, the turbine rotor and the tub section defining an annulus therebetween. A difference between the first reaction and second reaction is capable of urging a steam flow through the annulus for reducing a temperature of the turbine rotor.
