The W.B. Hall Resource Recovery Facility provides the city of Tulsa with a clean alternative to land-filling their municipal solid waste.  Over the course of a year this facility will process almost 370,000 tons of waste producing steam and electricity in the process.  Approximately 480,000 Tulsa residents are served by this facility.

Combustion Technology Upgrade:  In 2004, one of the three existing Martin® reciprocating grate systems at the Tulsa facility was replaced with the patented Aireal® Combustion System during a normal unit outage.  The retrofit was done by the original development company for the ACS technology prior to Novo's acquisition of the license rights for the technology.  This retrofit was done to improve the overall performance of the combustion system and decrease costs associated with operation and maintenance of the older reciprocating grate style units.  The performance comparison between the ACS unit and the two Martin units demonstrated the following:

• 77 percent reduction in annual boiler cleaning costs relative to martin units
• 52 percent reduction in particulate carryover compared to Martin units
• 73 percent reduction in off-line boiler cleaning hours relative to Martin units
• 54 percent reduction in NOx reagent use compared to Martin units
• Significant reduction in forced outages related to grate maintenance
• Significant reduction in grate  bar replacement costs
