Abstract

Inventia se refera la o instalatie de obtinere a clincherului de ciment, constituita dintr-un cuptor, un calcinator amplasat înaintea cuptorului, un schimbator de caldura avînd cicloane amplasate în trepte în doua ramuri paralele de gaze de ardere, care se gasesc în legatura, pe de o parte, prin cîte o conducta de alimentare cu gaze cu o conducta de evacuare a gazelor de ardere dintr-un ciclon, care comunica cu una din conductele de evacuare a gazelor de ardere provenite din cuptor si, pe de alta parte, cu o conducta de evacuare a gazelor de ardere provenite din calcinator, conducta de evacuare a materialului preîncalzit din cicloanele uneia din ramurile de gaze de ardere ale schimbatorului de caldura fiind în legatura cu conducta de alimentare în cicloanele celeilalte ramuri de gaze de ardere a schimbatorului de caldura. Instalatia este prevazuta dupa calcinator, pe partea dinspre gaze, cu doua separatoare, care comunica prin cîte o conducta cu cîte o alta conducta de alimentare cu gaze aferente celor doua ramuri de gaze de ardere ale schimbatorului de caldura, conductele respective fiind în legatura si cu o conducta de evacuare a gazelor dintr-un ciclon amplasat nemijlocit înaintea cuptorului prin intermediul cîte unei conducte de legatura, prevazuta fiecare cu cîte un sibar de reglare a cantitatii de gaze.
