Abstract

METODO PARA REDUCIR EL RIESGO DE RETROCESO DE CORONA EN UN PRECIPITADOR ELECTROSTATICO. EN UN METODO PARA REDUCIR EL RIESGO DE RETROCESO DE CORONA EN UN PRECIPITADOR ELECTROSTATICO (5) AL QUE SE CONDUCEN GASES CALIENTES CON POLVO VIA UN CONDUCTO DE SUMINISTRO DE GAS (4) Y A TRAVES DEL CUAL SE LLEVAN LOS GASES PARA LA SEPARACION DEL POLVO, SE REDUCE LA TEMPERATURA DEL GAS Y SE INCREMENTA LA HUMEDAD DEL GAS MEDIANTE LA ADICION A LOS GASES, ANTES DE QUE PASEN POR EL PRECIPITADOR (5), DE AGUA QUE SE EVAPORA EN LOS GASES. DE ESTA FORMA, UNA CANTIDAD DE AGUA, PROPORCIONADA PARA PROVOCAR LA REDUCCION DESEADA DE LA TEMPERATURA, SE INYECTA EN EL CONDUCTO DE SUMINISTRO DE GAS (4). UNA CANTIDAD DADA DE PARTICULAS DE POLVO SEPARADAS EN EL PRECIPITADOR (5) SE EMPLEA COMO PORTADOR DEL AGUA Y SE RECICLA INYECTANDOSE EN EL CONDUCTO DE SUMINISTRO DE GAS (4) JUNTO CON EL AGUA TRANSPORTADA POR LAS PARTICULAS DE POLVO.
