The new Valmet Recovery Ash Analyzer measures the ash composition at the electrostatic precipitator (ESP) and determines the ash melting temperatures which describe the corrosiveness and stickiness of ash. It is an innovative solution to reduce unplanned boiler shutdowns caused by superheater corrosion or boiler plugging and provide guidance for ash treatment and sootblowing need.
Valmet Ash Balance Advisor is an additional option to maximize the Valmet Recovery Ash Analyzer’s advantages and optimize ash treatment for significant cost savings in sodium make-up. Operators are provided with an online view of ash balance and boiler operation with real-time indicators of fouling and corrosion risks providing an operational target for cost-effective ash treatment amount or dump volume.
