BESTIMMEN UND ÜBERWACHEN VON PARAMETERN IN KESSELANLAGEN.

摘要

Concentration cycles, percent life holding time for a component in the boiler and continuous treatment concentrations are monitored or determined in a boiler system by adding to the feedwater an inert tracer in a predetermined concentration CI, which reaches a final concentration CF at steady state in the boiler and which exhibits a blowdown concentration Ct at different points in time. The component is an inert tracer having no significant carryover in the steam, nor significant degradation during boiler cycles. The tracer is monitored by continuously converting a characteristic of its concentration to an analog which may be recorded as a function of time.
