ABSTRACT:
This invention relates to the measurement of the dryness of steam supplied to steam-powered processes, and in particular to a method of making such measurements, and to methods of using the measured dryness fraction to obtain further information about the process plant and the steam supply.
In particular, the invention is applicable when fluid is supplied via a steam separator to a process, and it relies upon storing values for the efficiency of the separator at a plurality of input steam and condensate mass flow rates and a plurality of input fluid temperatures or pressures. Methods disclosed herein use one of these values, together with measured output steam and condensate mass flow rates, to calculate the dryness of the steam.
