Apparatus for treating raw material with a treating gas

摘要: An apparatus for treating raw material comprises a mixing chamber having fuel and air inlets admitting therein which are mixed to produce combustible mixture. A combustion receives the mixture burns same evolve hot products of fed directly into an adjoining conditioning chamber. Additional gas is supplied with form conditioned prescribed temperature composition. To promote rapid uniform gases hence gas, connected has volume one one-half six times greater than that disposed downstream from both preconditioned be treated acted thereon by while temporarily stored in
