    2019-4-2 · The fuel consumption required to generate superheated steam is greater than that required to generate an equivalent volume of saturated steam. However, the overall energy efficiency of the steam plant (the combination of boiler, superheater, piping and machinery) generally will be improved enough to more than offset the increased fuel consumption.

  • Why, in the thermal power plant sequence of a

    Furthermore, if economiser is placed before superheater, feed water is directly converted into steam before entering into boiler and steam passing through superheater cannot be superheated as temperature of flue gases is not so high that can superheat the steam. This is the reason for maintaining the sequence. There could be other reasons.
