Abstract
A system and method for continually and automatically measuring the quality of steam includes a steam dryness/superheat meter and a non-condensable gases (NCG) meter. The steam dryness meter includes a throttling calorimeter through which a steam sample enters at atmospheric pressure, sensors for sensing the pressure and temperature of the stream before and after it enters the calorimeter, a controllable heat input for supplying any additional energy necessary to superheat the steam sample, and logic for deriving the dryness from the collected data. The NCG meter includes a cooler for condensing the steam sample reservoirs into which the liquid and non-condensable gases are entrapped and measured, and logic for continuously deriving the NCG ratio from the collected data.
