Device for the fixing of heat accumulation segments and stator blades in axial flow turbines

摘要

In axial flow turbines with horizontally divided housing the device for the fixing of heat accumulation segments (6) and stator blades (7) comprises at least one stator solid ring (3), insertable together with the rotor (5) into the lower half of the outer housing (1), on the inner surface of which ring the heat accumulation segments (6) are fixed, recesses (2) being provided in the outer housing (1) for accommodation of the stator solid ring (3) and the stator blades (4) being fixed directly on the outer housing (1). The stator solid rings (3) can be arranged either on all or only on selected blade rows. Their temperature can be controlled independently of one another. <IMAGE>
