Abstract
"MéTODO DE COMBUSTãO". A formação de NOx na queima de combustível hidrocarbónico sólido como carvão é reduzida por obtenção, a partir da corrente de entrada de combustível sólido e ar, de uma corrente tendo uma razão de combustível sólido para ar maior do que a da corrente de entrada, e injetando a corrente assim obtida e uma pequena quantidade de oxigênio em um queimador (3) onde o combustível é queimado.
