Abstract

LA PRESENTE INVENCION SE REFIERE A UN METODO DE GASIFICACION DE LICOR NEGRO EN CALDERAS DE RECUPERACION, DEL TIPO QUE TIENE UN ELEMENTO INFERIOR QUE SE LLAMA HORNO INFERIOR Y UN ELEMENTO SUPERIOR QUE SE LLAMA HORNO SUPERIOR, ASI COMO PULVERIZADORES PARA INTRODUCIR EL LICOR NEGRO EN LA CALDERA ENCIMA DEL HORNO INFERIOR Y TAMBIEN UN NUMERO DETERMINADO DE NIVELES DE AIRE DE COMBUSTION; SE AÑADE EN EL MARCO DE ESTA INVENCION, AIRE ENRIQUECIDO CON OXIGENO AL AIRE DE COMBUSTION O, DIRECTAMENTE, EN EL HORNO INFERIOR A, POR LO MENOS, UN NIVEL DE AIRE POR DEBAJO DE LOS PULVERIZADORES DE LICOR CON EL FIN DE CREAR LAS MEJORES CONDICIONES POSIBLES DE REDUCCION EN EL HORNO INFERIOR, VOLVIENDO A DISTRIBUIR A PARTIR DEL AIRE DE COMBUSTION DEL HORNO INFERIOR, AIRE QUE NO SE NECESITA EN EL MISMO DESPUES DE DICHA ADICION DE AIRE ENRIQUECIDO CON OXIGENO, LO QUE PERMITE REDUCIR NOTABLEMENTE LA VELOCIDAD ASCENDENTE DE LOS GASES POR DEBAJO DE LOS PULVERIZADORES DE LICOR NEGRO, E INTRODUCIENDO DICHO AIRE DE COMBUSTION DIRIGIDO PARA DISTRIBUIR EN EL HORNO SUPERIOR, CREANDO, DE ESTE MODO, UNAS CONDICIONES DE REDUCCION Y UNA TEMPERATURA CONTROLADA EN EL HORNO INFERIOR PARA EL CONTROL DE LA EMISION.
