Abstract

An ejection gas flow is processed using catalyst in the presence of an oxygen, so that the concentration of the harmful substance in the condensation impossibility section is decreased under 1 milligram per cubic meter at standard temperature and normal pressure. The first ejection gas flow is heated to at least about 500 degrees celsius with atmospheric pressure within second container (18) currently dried.
