A method and apparatus for measuring of non-condensable gases and vapors in a steam - gas mixture

摘要

The method and device for measuring of non-condensable gases and vapors in a steam - gas mixture continuously or discontinuously conducts a sample quantity of the steam - gas mixture by means of a capacitor (2), from which a mixture of condensate (3) and gas bubbles (4) and a line (5) exit. On the line (5) is a sensor (6) are connected in a flow rate only one of the components of the mixture of condensate (3) and gas bubbles (4) measures quantitatively and a corresponding output signal to an evaluation unit (9) delivers. This is monitored in addition, significant changes of the output signal of the sensor (6) and determines from it by calculation of the mass flow of the other component. The mass flow can in this case the volume per unit of time or the mass per unit of time of the component be. The component, the of the sensor (6) is measured, it can alternatively either the condensate or the gas.
