Abstract

Procedeul de obtinere a cimentului, conform inventiei, se caracterizeaza prin aceea ca, în scopul îmbunatatirii randamentului termic, se amesteca curentul de gaze evacuat din cuptor dupa o cedare prealabila de caldura materialului brut, cu gazul evacuat din calcinator care este alimentat printr-un ciclon într-o camera de amestec, dupa care curentul de amestec gazos este divizat în cele doua ramuri ale schimbatorului de caldura, curentii partiali evacuati din camera de amestec reunindu-se înainte de evacuarea din schimbatorul de caldura, în mod sine cunoscut. Instalatia de realizare a procedeului, conform inventiei, în scopul îmbunatatirii randamentului termic, cuprinde si un ciclon alimentat cu gaze de ardere din cuptor printr-o conducta, un ciclon alimentat cu gaze de ardere din cuptor printr-o conducta, un ciclon alimentat cu gaze evacuate din calcinator, curentii de gaze fiind evacuati din cicloane prin niste conducte care se unesc într-o camera de amestec si care comunica, conductele de alimentare cu gaze prevazute pentru cele doua ramuri ale schimbatorului de caldura.
