Matrix's Mobile Test Units (MTU’s) are capable of continuous weigh feeding of difficult powders for temporary or experimental purposes. The system is complete with full instrumentation and controls including wireless communication with PC HMI.

Matrix provided the system engineering and critical equipment package for Smurfit-Stone in Panama City, Florida. This system was designed to accept petcoke from trucks and feed a lime kiln burners from a 180 ton silo. A pneumatic conveying system with a variable rate blower delivers petcoke to the burner in accordance with their specific air flow requirements. Control of the Matrix system was integrated into their existing DCS. Using the Matrix DENSI-FEED System they were able to co-fire petcoke with fuel oil or natural gas and are feeding at rates as high as 3.80 tons per hour (115 MMBtu/hour).
