We have a boiler rated at 1550psi and 930F for electrical generation for local utility. The turbine is rated for same. However, the operators are running this boiler at reduced pressure (1300) with the same superheat temp. The inspection cert. still says that the full rating is available. My concern is for the turbine (long term), what effect could this have, and in the short term, How would this effect boiler,turbine effiency with reduced pressure entering turbine?
