Abstract
An FGC conditioning agent injection-control system, where conditioning agent over- or under-injection can be prevented while maximizing a precipitator's performance. The injection rate is typically regulated using feed forward signal proportional to the coal flow, which could be represented by the boiler load augmented by a feedback from the voltage control and electrical conditions in the ESP, sulfur dioxide emissions signaling any changes in the coal quality, opacity monitor data, and other parameters. Both the feed forward and the feedback information and signals from the existing injection skids are analyzed, and the optimal injection rate for the current conditions is determined. With fast, continuous and automatic sampling and analysis, the system responds quickly as each parameter changes, recalculating the optimal injection rate and automatically sends the new injection set-point to the injection skid.
