METHOD OF NITRIC OXIDES REDUCTION AND SOOT TREATMENT BY USING HYDROGEN PEROXIDE SOLUTION ALCOHOL OR HYDROGEN PEROXIDE SOLUTION /ALCOHOL MIXTURE

摘要

PURPOSE: A method for NOx reduction by using hydrogen peroxide solution, alcohol or hydrogen peroxide solution/alcohol mixture is provided, which can remove effectively NOx and soot contained in exhaust gas stream of various burners and diesel engines. CONSTITUTION: The method comprises the steps of spraying mixture of hydrogen peroxide of 1 to 15 wt.% concentration, water and alcohol of 1 to 1.5 wt.% concentration at a weight ratio of 1-7.5:1-7.5:85-98 through reagent spraying nozzles(3) to exhaust gas coming from a combustion chamber(1) and containing nitrogen oxide (NOx) at 400 to 800 deg.C at a reactor(2); spraying water through water spraying nozzles(6) to condensate at a cooling tower(5).
