INSTALLATION AND METHOD FOR THE THERMAL TREATMENT OF FLOURY RAW MATERIALS

摘要

The invention relates to an installation and a method for the thermal treatment of floury raw materials. Said installation comprises a separate combustion chamber for the pre-calcination of raw materials, a sintering furnace, and a calcinator through which the waste gases of the sintering furnace flow. The combustion chamber is connected to the calcinator by means of a connection line, and additional fuel and combustion air are supplied to the calcinator. The additional fuel is supplied in a region located between the connection line ending in the calcinator and the supply line of the combustion air.
