The effect of black liquor firing temperature on atomization performance

T. Helpiö, Ari Kankkunen

Abstract

Experimental study of the effect of black liquor firing temperature on the atomization performance of industrial-scale splash plate nozzles showed that flash boiling of the liquor in the nozzle flow tube decreases the mean drop size of the spray. In addition, flashing accelerates the flow in the flow tube and increases the initial drop velocity. Flashing also changes the direction of the spray. Comparing drop size data to earlier data obtained with small-scale nozzles showed that the industrial-scale data and the small-scale data agreed. Application : small-scale measurements can successfully predict the atomization performation of full-scale splash plate nozzles.
