Abstract:
1. A method for assembling a turbine, said method comprising: positioning an annular nozzle carrier radially inwardly from a casing such that a cavity is defined between the nozzle carrier and the casing; positioning a gusset structure within the cavity to couple the casing to the annular nozzle carrier, such that the gusset structure provides support between the casing and the annular nozzle carrier; coupling a flange to the casing, such that said flange extends from a leading edge of the casing towards a leading edge of the nozzle carrier; and extending a seal ring between the nozzle carrier and the casing such that the seal ring seals the cavity, wherein the seal ring is positioned between the flange and at least one of the nozzle carrier and the casing, wherein the seal ring extends from the casing leading edge towards the nozzle carrier leading edge.
