After leaving rotary Kiln 1, flue gases pass through a cyclone stage and then through a scrubber to remove entrained dust. Dust recovered in the cyclones is fed back to the Kiln 1 entrance. Table 1 summarizes the typical operating condition of Kiln 1. In rotary Kiln 2, flue gases pass through an electrostatic precipitator to remove dust.
