Ash Treatment Systems
Lundberg’s Ash Treatment System (ATS) processes the sulfated ash from the chemical recovery boiler precipitator to remove potassium and chlorides and allows for the recovery of sodium sulfate crystals.
The ATS system is designed to reduce the concentration of chlorides and potassium in the recovery cycle. Reducing the potassium and chloride content will effectively increase the “sticky temperature” for the ash in the boiler flue gases, thus reducing both the frequency of boiler washes and steam consumption for soot blowing. The ATS system is designed to provide 85% sodium recovery and 85% removal efficiency on both chlorides and potassium from the incoming ash feed. The ATS system can be integrated into you existing evaporator set, to improve steam utilization and reduce operating costs.
