Valmet Recovery Boiler Sootblowing Optimizer

The amount and quality of dust and potential carry-over are a direct result of the burning process in the boiler furnace. Boiler section fouling is related to the amount of dust as well as to boiler construction and production rate. Fouling decreases heat transfer to the water and steam, and increases flue gas exit temperature thereby reducing the recovery boiler’s thermal efficiency. Extensive fouling also restricts the boiler availability.
