PURIFYINGMETHOD FOR EXHAUST GAS

摘要

PURPOSE:To eliminate NH3 exhaustion to the outside of the system and to throughly prevent the closure of machinery etc. due to the product of ammonium sulfate etc. by adding excess NH3 to the exhausted gas containing NOx and SOx to denitrate it due to the catalytic reduction, and by decomposing the excess NH3 with the spacified NH3 decomposing catalyzer prior to the desulfurization.
