Title: Research on droplet formation for application to Kraft black liquors. Technical report No. 1

Abstract

Two regimes of droplet formation from nozzles have been identified: a chaotic regime in which fragmentation of liquid results from the combination of initial liquid turbulence and viscosity of the surrounding gas medium; and an ordered regime in which droplet formation results from surface tension of the liquid, density of the gas medium and uniform oscillations in flow from a nozzle. Fragmentation and subsequent droplet formation in the chaotic regime result in a broad range of droplet sizes which is assumed to be undesirable for best operation of a Kraft Recovery Boiler. Production rates in the ordered regime are limited by transition into the chaotic regime. This project is concerned with droplet formation from jets and sheets of high solids black liquors in which large amplitudes of oscillatory flow can be applied which can assist the ordered fragmentation process to produce uniform droplets at higher production rates.
