Abstract

For the cooling of platforms (10) of turbine blades (2) a turbine assembly has at a separating gap (11) between a first (14) side wall of a first platform (10a) and a second (15) side wall of a second platform (10b) a sealing plate (19) arranged between said first (14) and said second (15) side walls for preventing a leakage of drive gas through said separating gap (11), wherein said sealing plate (19) is provided with at least one opening (21, 22) for allowing cooling gas to flow from a cavity (18) under the platforms (10a, 10b) to the upper face (12) of the platforms (10a, 10b) for forming a convective cooling of the first platform (10a) and for forming a film cooling along the upper face (12) of the second platform (10b).
