Measurement of Steam Consumption Spirax Sarco

Steam consumption can also be established directly, by measuring the mass of condensate collected in a drum over a period of time. This may provide a more accurate method than using theoretical calculations if the flash steam losses (which are not taken into account) are small, and can work for both non-flow and flow type applications.

the film drum dryer, units in which heat is transferred by conduction are suitable only for batch use. This limitation effectively restricts them to applications involving somewhat modest production runs. Radiant or so called “infra-red” heating is rarely used in drying materials such as fine chemicals, pigments, clays or synthetic rubbers.
