WebA high-pressure stage of steam turbine operates at steady state with inlet conditions of 6 MPa, t = 275.6°C, x = 1 (point C). Steam leaves this turbine stage at a pressure of 1.15 MPa, 186°C, and x = 0.87 (point D). Calculate the enthalpy difference (the work done by HP Turbine) between these two states. WebA break-away linkage connects the torque bar to the high-pressure control valve linkage and thus the high-pressure control valve. Due to the break-away linkage’s design, the HP control valve will not begin to open until all valves in the low-pressure (LP) valve chest are in the fully open position. When all low-pressure valves are fully open, steam is admitted to the …
