Abstract

Inventia se refera la un procedeu si o instalatie pentru fabricarea unui clincher de ciment. Procedeul, conform inventiei, consta în preîncalzirea fainii brute de ciment, eliminarea acidului în pat fluidizat, clincherizarea si apoi racirea clincherului obtinut. Eliminarea acidului se face la o temperatura de peste circa 850 degree C, în proportie de cel putin 95%. Pentru calcinare combustibilul cu continut de carbon se alimenteaza în proportie de circa 65% pentru eliminarea acidului sli circa 10% pentru calcinarea în cuptor. Arderea combustibilului se realizeaza cu cel putin doi curenti de gaze cu continut de oxigen, unul adaugîndu-se ca zag de fluidizate, iar celalalt se adauga ca gaz secundar, în doua trepte si fata de totalitatea treptelor de ardere apropape stoichiometric.
