FIELD: physics.
SUBSTANCE: invention relates to engineering physics, namely to determination of mass flow rate of wet steam in steam line of steam generator, can be used on steam generators of NPP and TPP. Method of determining wet steam flow rate in steam line of steam generator, including measurement in steam line: static pressure and pressure drop on two of its receivers, one of which opening open towards flow, and window of another – towards flow direction; calculation of mass flow from measured values and conversion coefficient; includes: measurement of degree of dryness of generated steam and mass flow rate of feed water of steam generator; value of dryness of steam and mass flow rate of feed water is recorded (memorized) on interval of stable state of measured values; calculating a fixed value of the conversion coefficient from a fixed value of supply water flow rate, static pressure, from the value of pressure drop on its receivers in the steam line; conversion coefficient is calculated by its fixed value and by current and fixed values of degree of dryness.
EFFECT: disclosed is a method of determining wet steam mass flow rate in a steam line of a steam generator.
