How does spray dryer work? - Lab Instrument Manufacturer

How does spray dryer work? - Lab Instrument Manufacturer

A spray dryer takes a liquid stream and separates the solute or suspension as a solid and the solvent into a vapor. The solid is usually collected in a drum or cyclone. The liquid input stream is sprayed through a nozzle into a hot vapor stream and vaporized. Solids form as moisture quickly leaves the droplets.

Jan 01, 2004 On the contrary, spray-dryers hardly exceed 70% SO 2 removal efficiency at 1–2 calcium to sulfur ratios (Ca/S), as opposed to values higher than 90% for wet scrubbing, making this technology attractive when SO 2 concentration in the flue gas is relatively low. In the spray-dry FGD process the hot flue gas is contacted with a fine spray of ...
