Abstract

Described herein is a method for controlling thermodynamic parameters of a steam (ST) that is supplied to a steam-using unit (3), said steam (ST) being obtained by mixing a first regulation steam (ST1) with a second regulation steam (ST2), regulating the respective flow rates (QST1, QST2) of said first and second regulation steams (ST1, ST2), said method being characterized in that it comprises the steps of : controlling the thermodynamic parameters of said steam (ST) on the basis of said flow rates (QST1, QST2) of said first and second regulation steams (ST1, ST2) so that to one and the same variation of the flow rates (QST1, QST2) of said first and second regulation steams (ST1, ST2) there always corresponds one and the same variation of said thermodynamic parameters of said steam (ST) and so that to a variation of one of said flow rates (QST1, QST2) there corresponds exclusively a variation of one of said thermodynamic parameters of steam (ST) that it is intended to control, maintaining all the other thermodynamic parameters of said steam (ST) constant.
