Abstract
"PROCESSO PARA AUMENTAR A EFICIêNCIA DE SUBST‰NCIAS QUìMICAS DE CONTROLE DE ESCóRIA PARA UNIDADE DE RECUPERAçãO DE SOLUçãO NEGRA E OUTRAS UNIDADES DE COMBUSTãO". A redução da escorificação é aperfeiçoada por se direcionar substâncias químicas de redução de escória em uma fornalha com o auxílio de modelagem da dinâmica do fluído computacional. A utilização da substâncias química e a manutenção da caldeira são aperfeiçoadas.
