Abstract
LA INVENCION SE REFIERE A UN METODO PARA REDUCIR EL CONTENIDO DE OXIDO AZOICO DE LOS GASES DE ESCAPE DE SISTEMAS DE CALEFACCION CON ALTAS TEMPERATURAS DE COMBUSTION. PARA LA REDUCCION EFICAZ Y RENTABLE SE PROPONE EN ESTE CASO QUE EL GAS DE ESCAPE SE SOMETA PRIMERO EN FORMA EN SI CONOCIDA, DENTRO DE UN MARGEN DE TEMPERATURA ENTRE APROXIMADAMENTE 700 Y 1.100JC A UNA REACCION DE GAS HOMOGENEA, MEDIANTE LA AÑADIDURA DE MEDIOS REDUCTORES PASANDOLO A CONTINUACION POR UN REACTOR DE RECUPERACION TERMICA, CUYO MATERIAL DE RECUBRIMIENTO DEL REGENERADOR POR LO MENOS EN LA ZONA DE TEMPERATURA ENTRE APROXIMADAMENTE 200 Y 500JC ESTA REALIZADO COMO CATALIZADOR PARA LA REDUCCION SELECTIVA DE LOS OXIDOS AZOICOS.
