Abstract

LA INVENCION SE REFIERE A UN METODO PARA QUEMAR LICOR NEGRO EN CALDERAS DE RECUPERACION, DONDE LA INTENCION ES OBTENER GASES CON UN BAJO CONTENIDO EN OXIDOS DE NITROGENO NO{SUB,X}. LA INVENCION SE CARACTERIZA POR QUE PARTE DEL AIRE DE COMBUSTION SE AÑADE CON UN ULTIMO SEGMENTO EN UN NIVEL SOBRE UN NIVEL MUY ELEVADO PARA QUE EXISTA UNA ATMOSFERA REDUCTORA EN UNA GRAN PARTE DE LA CALDERA Y DURANTE MUCHO TIEMPO AL MENOS 3-5 SEG. LA INVENCION TAMBIEN INCLUYE UNA CALDERA DE RECUPERACION PARA LLEVAR A CABO DICHO METODO.
