PULVERIZED FUEL SYSTEMS 

PRATVILLE, ALABAMA

PETROLEUM COKE DENSI-FEED™ SYSTEM 

Matrix provided the complete system engineering equipment package for IP in Prattville, AL.  At this particualr mill, we replaced a direct fire system for burning petcoke in the kiln with our modern DENSI-FEED indirect fire system.  This system was designed to accept petcoke from a pulverizer feed the lime kiln burner from a 180 ton silo.  Currently they are able to fire petcoke and fuel oil and are feeding at rates as high as 3.00 tons per hour (90 MMBtu/hour).

Jaykaypur Odisha, India

PETROLEUM COKE DENSI-FEED™ SYSTEM 

Matrix provided the complete system engineering and equipment package for J K Paper Limited, Unit: JKPM.  This was the first installation in India for petcoke fuel burning in a Lime Recovery Kiln.  Our DENSI-FEED pulrverized fuel system is performing flawlessly alongside fuel oil at 65-70% substitution levels in a kiln capable of 300 mtons CaO per day.  This system was designed to accept petcoke from a bulk bag delivery into a 240 mton silo.  Also, of significant importance, Matrix delivers the fuel through our delivery convey system burner over 650 ft (200m) away.

In addition to our patented system, Matrix provided construction management, commissioning and on-site training services for the mill.

 

Matrix also provided the burner for this non-domestic system, taking full responsibility for the complete reliability and success of the system including process fuel substitution performance guarantees.

The Mill has been extremely pleased with our petcoke fuel system performance as well as their lime kiln production and the fuel conversion.

HODGE, LOUISIANA

DUAL PETROLEUM COKE DENSI-FEED™ SYSTEM

 Matrix provided the complete engineering package for a dual discharge petcoke delivery system for Smurfit Stone Containerboard Division in Hodge, Louisiana.  The  system was designed to feed two lime kiln burners from a common 180 ton silo.  A dual discharge hopper bottom was specifically designed for two petcoke feeders.  It included dual pneumatic convey systems with variable rate blowers to deliver petcoke to the Coen burners in accordance with the manufacturer's specific air flow requirements.  The convey distance of the petcoke was in excess of 600 feet.  The system allowed the mill to substitute up to 90% ground petcoke for natural gas in each of their lime kiln burners.  The control of the Matrix feed equipment was integrated into Smurfit Stone’s existing DCS.  Matrix provided all the civil/structural, mechanical, and electrical engineering for the project.



 

PERDUE HILL, ALABAMA

DUAL PETROLEUM COKE DENSI-FEED™ SYSTEM

 Matrix provided the system engineering and critical equipment packages with silo for a dual discharge petcoke delivery system at Alabama River Pulp (ARP) in Perdue Hill, Alabama.  This system was designed to accept petcoke from rail or truck and feed two lime kiln burners from a common 180 ton silo.    A dual discharge hopper bottom was specifically designed for two petcoke feeders, though initially, ARP chose to implement the project in two phases and only installed one of the two petcoke feed systems.  Matrix Engineering commissioned the second line in late Spring 2008.  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 ARP’s existing DCS.  Currently they are able to fire petcoke and fuel oil as well as natural gas.

The first kiln’s system at ARP was proven and tested to 3.0 tph and is currently burning in excess of 2.4 tph of petcoke in combination with fuel oil.  Below is a picture of the flame at 2.5 tph with fuel oil.



SPRINGFIELD, OREGON

PETROLEUM COKE DENSI-FEED™ SYSTEM

Matrix implemented an engineering and equipment supply contract for a storage silo and petcoke feed system for Weyerhaeuser in Springfield, Oregon.    The system consisted of a 180 ton storage silo and a variable feed system specifically designed for the discharge of ground petcoke.  A variable rate blower was used to transfer the petcoke approximately 350 feet to the existing “coke-ready” burner.  All controls and display panels were integrated into the mill’s existing DCS system. Matrix provided the civil/structural, mechanical, and electrical engineering for the project.  System startup was conducted in December 2006.

Matrix is currently providing engineering services and critical equipment to MeadWestvaco for a 270 ton dual discharge petcoke delivery system with rail unloading capabilities.  The rail unloading line will extend in excess of 600 feet to the delivery silo where petcoke will be fed to two lime kilns.



PORT HUDSON, LOUISIANA

PETCOKE CONVEYING & FEED SYSTEM TROUBLESHOOTING 

Georgia Pacific contacted Matrix while experiencing problems during start-up of their on-site grinding facility.  Our Engineering Department provided assistance for an existing petcoke feed system that was not functioning as designed.  We were able to quickly diagnose the problem which involved the conveying air flow for the delivery silo dust collector.  The convey air flow was overwhelming the dust collector filter area.  We quickly engineered a new 4” line, provided and expedited a positive displacement blower to replace a centrifugal fan, which conveyed the same coke rate using 20% of the original air.  This completely eliminated the problem.

Georgia Pacific then asked Matrix to look at some chronic feeding problems they were experiencing with their existing burner delivery system.  Matrix Engineers evaluated the situation, and determined that it was due to a “bridge and flush” phenomenon, which caused a 20% swing in the average feed rates.  Matrix issued a complete report on the problem and recommended improvements.


PeTroCoke, Inc.

OWENSBORO, KENTUCKY - GRINDING PLANT UPGRADE 

Matrix Engineering provided a complete electrical system upgrade and the modernization and controls automation of PeTroCoke, Inc.’s Owensboro, Kentucky plant.  The entire electrical system was replaced from the main service disconnect to all of the equipment and instrumentation.  The new control system consisted of an Allen Bradley PLC and RSView32 computer operator interface.  The electrical upgrade controls a mill feed system, a hammer mill, and a gas-fired burner system for drying the petcoke.  Ultrasonic instrumentation continuously monitors the finished product silo and controls a bulk truck load-out system.  Matrix personnel assisted in complete system check-out and start-up and were able to minimize downtime without affecting delivery of customer orders.  Due to automatic control of product feed and burner temperature, the plant throughput was improved dramatically.
