GAS TURBINE FOR POWER PLANTS HAVING A HONEYCOMB SEAL DEVICE

A gas turbine for power plant (1) comprises at least a combustor (5) and a turbine (4) downstream the combustor (5), wherein the combustor comprises a downstream end (21) facing the turbine (4) and provided with an inner groove (41). The turbine (4) comprises a plurality of first stator vanes (44), each first stator vane (44) comprising an inner platform (43) provided with a tooth (45) projecting in part inside the inner groove (41). A plurality of seals are provided housed in the inner grooves (41) of the combustor downstream end (21) and are configured for cooperating with the vane teeth (45) for sealing each can combustor to the turbine interface. At least a seal is a honeycomb seal device (20), the honeycomb seal device (20) being an assembly comprising a honeycomb body (24) made of a plurality or radial cells and a shield body (30) covering at least the part of the honeycomb body (24) cooperating with the vane tooth (45).
