摘要： A gas turbine blade having a plurality of shower head cooling holes (1), bored in a blade leading edge portion, are arranged along a single line which is biased so as to correspond to the direction of swirling flow in a combustor. The swirling flow is clockwise or counter-clockwise. In particular, if the flow is clockwise, the cooling holes (1) are biased to the left hand side, as seen from upstream of the blade, toward a blade hub side (HS) from a blade tip side (TS). Also, if the flow is counter-clockwise, the cooling holes (1) are arrayed on one line which is biased to the reverse side relative to the latter case. The influence of the swirling flow is thus avoided, and the pressure at each position of the cooling holes (1) is constant, so that uniform cooling can be attained.

摘要： A plate spring 6 having a hook-shaped cross section from the lower part is installed in the neighborhood of one end “b” of an impingement-cooling plate 4. One end “c” on the lower side is fixed to a rib 1d by welding, while the other end “b” on the upper side is free, which makes it closely contact with the neighborhood of the other end “b” of the impingement-cooling plate 4 by the elastic force thereof. This state makes it possible to seal a gap formed between the impingement-cooling plate 4 and a transition piece 1 on the side of a rib 1d, preventing thermal stress generated in the rib 1d, for example, from affecting the impingement-cooling plate 4.

摘要： A gas turbine cooling blade maintains a cooling effect and prevents sticking of deposits to the belly surface of the blade. The blade is provided with a relatively big cooling hole formed on the belly part of a hollow stator blade at an acute angle with the blade surface for blowing out cooling air. A relatively small cooling hole is disposed downstream of the big hole at a more acute angle with the blade surface to bring a jet of cooling air along the blade surface.

摘要： This gas turbine includes a turbine cooling structure of cooling a turbine by using cooling air and a filter that reduces dust in the cooling air on an upstream side of the turbine. Furthermore, the gas turbine includes a supply pipe for supplying the cooling air to the filter, a branch pipe that is branched from the supply pipe on an upstream of the filter, and a unit that calculates or estimates a circulation amount of dust in the cooling air. In this gas turbine, at a time of start-up of a turbine, the supply pipe is closed and the branch pipe is opened, and when the circulation amount of dust in the cooling air becomes equal to or less than a predetermined threshold, the supply pipe is opened and the branch pipe is closed.
