PRODUCTION OF CEMENT CLINKER AND PLANT TO THIS END Russian patent published in 2014 - IPC F27B7/20 C04B7/43 

FIELD: process engineering.

SUBSTANCE: set of inventions relates to production of clinker cement. Proposed method comprises steps whereat first and second stock portions 6, 7 are heated, calcium carbonate making the main component in first and second cyclone heaters 5 and 7, respectively. First and second heated stock parts 41, 61 are pre-annealed with gas application 9 for fuel combustion in reactor 1 with fluidised bed 13. Flow of fumes 8 produced by reactor 1 without backflow to reactor 1 is directed into second cyclone reactor 7. Annealed stock is roasted to obtain clinker in rotary furnace 2. Fumes 18 produced by rotary furnace 2 are directed into first cyclone heater 5. Clinker obtained in cooler 3 is cooled at forcing of cooling gas via clinker at the level of rotary furnace outlet. Fluidising gas represents gas 8 with content of oxygen of 90-100 % and low rate lower than 2 m/s.

EFFECT: facilitated complexation.
