Abstract

"REDUçãO SIMULTâNEA EM NO~ x~ E CARBONO EM CINZAS PELO USO DE MANGANêS EM QUEIMADORES DE CARVãO". A presente invenção refere-se a um aditivo e um método para reduzir simultaneamente tanto o carbono nas cinzas, quanto os níveis de produção de NO~ x~ que resultam da combustão do carvão pelo uso de pelo menos um aditivo contendo manganês. Uso de um aditivo contendo manganês em um forno de utilidade de queima a carvão, resulta tanto no abaixamento do teor de carbono nas cinzas quanto em emissões mais baixas de NO~ x~.
