Title Effect of water temperature on the effectiveness of dust suppression by spraying
Original title Vlijanie temperatury vody na ėffektivnost' pylepodavlenija orošeniem [in Russian]

Abstract The effectiveness of wet dust control is enhanced by encouraging condensation of water on the surface of dust particles. This can be achieved by spraying water at a temperature below the dew point. In an experimental wet dust collector (illustrated), an air stream containing 1540-1850mg dust/m3 was passed through a spray of temperature-controlled water. A 40░C spray reduced the dust level to 190mg/m3, but a 7.5░C spray reduced it to only 64mg/m3. Besides improving dust collection, the use of cooled water in mine ventilation systems would remove excess heat generated by electrical equipment.
