Valmet's crystallizers are designed to perform very close to the theoretical maximum limits of the ash crystallization process.
Ash crytallization offers superior efficiency in treatment of recovery boiler ash.
Valmet's ash crystallization technology has been engineered for maximum performance. The rates of recovery and removal are very close to the theoretical maximum limits, and to give the mill the lowest possible operating cost, Valmet's crystallizers can be energy integrated with the mill's processes.
The crystallizer at the APP OKI mill went into operation in 2017. The startup was smooth and according to plan. The design capacity of that plant was 920 tons of ash per day.
The most recent crystallizer from Valmet will be the one in Metsä Fibre's new mill in Kemi, Finland.
