Abstract

Un reactor o combustor de CFB, que tiene separadores de partículas primarias del tipo de impactos, recoge partículas sólidas desde una corriente circulante de gases de combustión y materiales sólidos y devuelve las partículas recogidas a lo largo de un suelo plano inclinado o sustancialmente horizontal hasta una porción inferior del reactor o combustor para su subsiguiente recirculación.
