Method and apparatus for cooling combustor liner and transition piece of a gas turbine

A method and apparatus for cooling a combustor liner and transitions piece of a gas turbine include a combustor liner with a plurality of circular ring turbulators arranged in an array axially along a length defining a length of the combustor liner and located on an outer surface thereof; a first flow sleeve surrounding the combustor liner with a first flow annulus therebetween including a plurality of axial channels (C) extending over a portion of an aft end portion of the liner parallel to each other, the cross-sectional area of each channel either constant or varying along the length of the channel, the first flow sleeve having a plurality of rows of cooling holes formed about a circumference of the first flow sleeve for directing cooling air from the compressor discharge into the first flow annulus; a transition piece connected to the combustor liner and adapted to carry hot combustion gases to a stage of the turbine; a second flow sleeve surrounding the transition piece a second plurality of rows of cooling apertures for directing cooling air into a second flow annulus between the second flow sleeve and the transition piece; wherein the first plurality of cooling holes and second plurality of cooling apertures are each configured with an effective area to distribute less than 50% of compressor discharge air to the first flow sleeve and mix with cooling air from the second flow annulus.

Turbine fracturing equipment

The invention discloses turbine fracturing equipment. The turbine fracturing equipment comprises a transporting device, a turbine engine, a reduction gearbox, a transmission mechanism and a fracturingpump, wherein the output end of the turbine engine is connected with one end of the reduction gearbox; the other end of the reduction gearbox is in transmission connection with the fracturing pump; the transportation device is used for bearing the turbine engine, the reduction gearbox, the transmission mechanism and the fracturing pump and comprises a chassis; the chassis is provided with a transporting section, a bearing section and a lapping section which are connected in sequence; when the turbine fracturing equipment is in a working state, the bearing section can be contacted with the ground; and when the turbine fracturing equipment is in a transporting state, the bearing section does not make contact with the ground. The turbine fracturing equipment has the beneficial effects that the equipment adopts the design of linear connection and a special chassis, so that the gravity center of the turbine fracturing equipment is doubly reduced, and the stability and the safety are well ensured; the structure is simpler, and the investment cost and the operation cost are reduced; the collapse risk of the whole fracturing site is reduced; and the turbine fracturing equipment is good intransmission property and is suitable for long-time and bulky load continuous operation conditions.
