METHOD OF DETECTING AND REDUCING CONTAMINATION IN PAPERMAKING BOILER SYSTEMS
摘要
This invention relates to a method and system for detecting contamination of boiler condensate and/or boiler feedwater in a papermaking process. The method includes measuring an oxidation-reduction potential at one or more locations in the boiler condensate and/or the boiler feedwater of the papermaking process with one or more corrosion stress monitoring devices. A controller is operable to assess whether the measured or a calculated oxidation-reduction potential is within an optimum range. The controller is operable to cause transmission of a signal to direct feeding an effective amount of one or more reductants and/or one or more pH-controlling chemicals into the boiler feedwater and/or one or more a satellite feed locations of the papermaking process.
