Abstract
The removal of dust particles using two-phase steam-water droplet mixtures has been studied. Two-phase steam-water droplet jets obtained by the flashing expansion of subcooled water, through convergent/divergent nozzles, have been characterized. The water droplet sizes and velocities were measured through the use of stroboscopic photography and laser-doppler velocimetry, respectively. A theoretical model using one-dimensional mass, momentum, and energy balances together with the concept of a critical Weber number criterion was developed to predict water droplet sizes and velocities. The agreement between measurements and predictions was reasonable. A theoretical model for predicting dust collection efficiencies of a two-phase scrubber was developed. It was determined that dust collection efficiencies exceeding 99 pct for basic oxygen furnace flue gases could be obtained using a two-phase scrubber.
