Boiler Efficiency and Steam Quality: The Challenge of

During periods of low steam demand, or when all the use points require pressure-reducing stations, boilers are often operated at substantially less than design pressure. While operating at lower pressure can, in some boilers, provide slightly higher energy efficiency, low-pressure operation also reduces steam quality.
