<p>SPECIFICATION Title of the Invention: A Method and an Apparatus for Burning the Material for the Manufacture of Cement A method and an apparatus for burning the material for the manufacture of cement, which comprises: setting up a calcining zone by forming a constriction in the chargingend duct of the kiln, providing a riser duct with a conicylindrical lower portion on the constriction, connecting a secondary-air intake duct to the riser duct, and installing inside the riser duct a combustion system so positioned as to inject fuel toward the center of the duct; disposing the calcining zone between the suspension preheater and the kiln; introducing the material preheated by the suspension preheater into the upper end of the calcining zone, while, at the same time, supplying secondary air for combustion of fuel to the riser duct, thus calcining the material with the ascending, swirling stream of the resulting combustion gas; and then separating the calcined material from the exhaust gas in a separator and feeding the material to the kiln.</p> |
