Abstract

PURPOSE:To accelerate the flow of gas passing through the catalyst layer and remove soat from the layer efficiently by injecting a part of exhaust gas from the outlet side of a fixed bed type dry denitration reactor after boosted from a nozzle on the upstream of the catalyst after boosted with a fan without use of special gas for cleaning.
