      When New steam pressure is reduced, what is the impact on the operation of the turbine?

      If the new steam temperature and other operating conditions remain unchanged, the new steam pressure drops, a load drop. If the load is maintained unchanged, the steam flow increased. When new steam pressure drops, the regulating stage enthalpy drop reduce, increase degree of reaction, the final stage of enthalpy drop increase, the reaction was reduced, for the total axial thrust of the unit have no big change, or did not change significantly, the new steam pressure decrease, unit steam consumption increases, the economy is reduced, when the new steam pressure drops more, to maintain the rated load, the flow rate exceeds the flow capacity of the final stage, so mile and axial thrust blade increases, so should limit load.
