    In variable pressure operation, boiler pressure is varied to meet turbine requirements. This can significantly improve cycle efficiency when operating at low loads (15 to 40% of maximum continuous rating, or MCR). However, boiler response to turbine requirements is slower in this mode. When fast response is needed, pressure increments are used.Get Price
