Abstract

Inventia se refera la un procedeu si o instalatie pentru fabricarea clincherului de ciment în trepte prin procedeul uscat, utilizînd combustibil lichid. O fractiune din totalul combustibilului este introdusa în conducta de alimentare cu faina preîncalzita a cuptorului, fara pulverizare si fara aer de combustie, amestecîndu-se cu întregul flux de material la circa 800 degree C. Ulterior are loc combustia acestuia în prezenta oxigenului admis prin cuptor sau prin conducta separata. Instalatiile de clincherizare existente, constînd din cuptor rotativ si preîncalzitor în suspensie care utilizeaza combustibil lichid, se pot transforma fara dificultate si fara cheltuieli importante, astfel ca o parte din totalul combustibilului pentru clincherizare sa fie ars în zona de ardere existenta a cuptorului rotativ, diminuîndu-se consumul specific de refractare bazic, ca urmare a reducerii solicitarii termice a zonei mentinute. Combustibil lichid se introduce la prima treapta de ardere, nepulverizat printr-un dispozitiv simplu si fiabil.The invention relates to a process and plant for the production of cement clinker in steps by dry process using liquid fuel. A fraction of the total fuel is introduced into the furnace feed furnace without spraying and without combustion air, mixing with the entire material stream at about 800 degrees Celsius. Then combustion is carried out in the presence of the oxygen admitted through the furnace or through the separate pipe. Existing clinker plants consisting of a rotary furnace and a preheater in liquid fuel suspension can be transformed without difficulty and without significant expense so that part of the total clinker fuel is burned in the existing combustion zone of the rotary kiln, -the specific consumption of basic refraction as a result of the reduction of the thermal demand of the maintained area. Liquid fuel is introduced into the first combustion stage, not sprawled by a simple and reliable device.
