Abstract
In the purification of gases generated in metallurgical and similar furnace operations, the impurities include solid particles and compounds or elements which are gaseous at the furnace temperatures and only form solid or liquid at temperatures approaching ambient conditions. Proper cleaning therefore requires cooling of the gases to at least the water dew point to cause these impurities to form as particles or droplets. This invention describes an apparatus for collecting such particles or droplets in which a charging device and condensation equipment are combined to provide a simple, yet effective apparatus at a fraction of the cost of conventional apparatus.
