ABSTRACT:
A preheating apparatus for particulate material includes a plurality of vertical chambers, a temperature sensor within each chamber and a particulate discharge mechanism. Each chamber is segregated from an adjacent chamber by a vertical wall and includes a material inlet for receiving particulate material, a material outlet for discharging particulate material, a gas inlet for receiving a gas, and a gas outlet for exhausting gas. The temperature sensor is located within a chamber so as to sense temperature of the gas being exhausted from each chamber. A particulate discharge mechanism discharges particulate material within each chamber through the material outlet, with a flow rate adjusted as a function of temperatures sensed by the temperature sensor. A method for preheating particulate material includes sensing temperature of the gas existing each chamber and adjusting a flow rate of the particulate material through each chamber as a function of sensed temperature of each chamber.
