ABSTRACT:
A process and apparatus for manufacturing low sulfur cement clinker from cement raw meal containing sulfur or with fuel containing high levels of sulfur or a combination thereof. The process is carried out in an apparatus which includes a preheater, calcining furnace, clinkering furnace and clinker cooler. A separate source of fuel is added to the feed end of the kiln to maintain reducing conditions and temperatures for decomposing the sulfur compounds. Fresh air is added to the riser duct connecting the clinkering furnace with the calcining furnace and the preheater for converting sulfur dioxide to sulfur trioxide. Calcium oxide is added to the riser duct for absorbing the sulfur trioxide to form calcium sulfate. The calcium sulfate is then removed by a gas solid separator from the system. Excess fuel added to maintain reducing condition at the feed end is utilized in the calcining furnace.
