PRATTVILLE, ALABAMA - PETCOKE PULVERIZER & DENSI-FEED™ SYSTEM

Matrix provided the complete system engineering and equipment supply package for IP in Prattville, AL.  This mill actually pioneered coke burning in lime kilns back in the 1980's.  However, this first petcoke system was a direct-fire unit which received raw coke into a pulverizer and blew it directly to the kiln burner.  As it turned out, this method was very difficult to control since nearly all of their combustion/primary air into the kiln was required to convey the coke out of the pulverizer.  As a result, they could not burn as much as they wanted and their kiln lacked turn down and the ability to optimize or flame shape and good CaO production.
