"Regulations require us to meet an annual average of .46 pounds per million Btu NOx on our Unit #4 boiler by the end of 1999. We had planned a major burner replacement using OEM-type equipment. RJM Corporation was selected from other vendors based on their experience and comparable prices. We asked for a design that would decrease the NOx and not increase the unburned carbon levels. RJM furnished the equipment and we had it installed by a contractor. Everything fit, and even though there was one small glitch, it was corrected right away. We've seen no overheating or other problems; it just works. I like that!"

"We've worked with RJM Corporation for more than 10 years on various projects relating to two coal-fired boilers and our oil-fired Unit #3. For this unit, RJM installed low NOx tips to help us comply with emissions requirements. RJM enabled us on Unit #3 to meet opacity restrictions for the state of New Jersey. RJM also performed air flow and temperature profiling for the two coal-fired units. They installed a common non-RJM manufactured SNCR handling system on the three units, and have helped maintain these systems. RJM is an excellent company!"

"We began working with RJM Corporation in 1996 on two of our coal-fired boilers to reduce NOx emissions to meet Clean Air Act requirements. On Unit #7, put into service in 1967, RJM performed diagnostics and modeling. On Unit #8, which was placed into service in 1982, RJM also performed the necessary diagnostics and modeling, and added customized stabilizers. We are very satisfied with RJM's work. We were able to modify Unit #8 for less than new burners would have cost. We also were able to comply with the Clean Air Act requirements for both units prior to the January 2000 deadline. We've had no problems with the equipment since it was installed. The good news is that we haven't needed RJM back for these units!"

"Initial phase of work with RJM Corporation was to increase the combustion efficiency on our 1950-vintage oil-fired Unit #2 boiler to come into compliance with the 1990 Clean Air Act. Kudos go to RJM for their forte with technology and modeling techniques to analyze the combustion process. RJM customized flame stabilizers and atomizer tips for the 12 burners in the front of the boiler. Whereas boiler OEMs wanted to take away the old burners and put in expensive new burners, RJM's engineering optimized our old equipment and this retrofit saved a huge capital expense.

"Another boiler, Unit #3, also needed to come into NOx compliance for the Clean Air Act but a burner modification was not feasible. Instead RJM, through computerized modeling, provided the engineering and design for a SNCR chemical injection system. RJM determined what regions of the boiler had the appropriate temperature for the location of the chemical injectors for maximum NOx reduction. RJM also supplied all the hardware in a skid-mounted design. The system, which was commissioned in July 1999, is working terrific. RJM's field engineer worked with us to optimize the system, and now we are exceeding requirements with lower NOx levels."

"We needed to bring our coal-fired boiler into NOx compliance for the annual ozone season. We contracted with RJM Corporation to develop an SNCR system for our 1954-vintage boiler to help with NOx emissions, as well as high unburned carbon levels and opacity problems. RJM discovered what a boiler OEM did not five years prior: the boiler had poor combustion capabilities. RJM talked sense — they measured the air and fuel flow and determined what was necessary for efficient combustion. The results have been wonderful. NOx emissions are 25% lower, as contracted by RJM, and probably an additional 25% lower due to improvements in the combustion process. It's also a plus that we've reduced the unburned carbon levels and can now burn fuel more effectively."

"Great technology! We achieved the required NOx reductions at Schiller Station using RJM modifications at much less cost than retrofitting with low NOx burners."

"I started working with RJM Corporation in 1992 when our two 1960 oil-fired burners needed to comply with Phase I of the Clean Air Act Amendment. RJM initially performed burner modifications and boiler balancing and tuning on both units to satisfy those requirements. For Phase II, RJM installed SNCR systems on both units. During the boiler tuning process, I gained respect for RJM's flexibility in working with our station people. RJM is different from a lot of other companies — they excel in their follow-through. They are very conscientious and genuinely concerned about completing the job. RJM's responsiveness to customer needs is obvious. With RJM's work, we were able to have the two boilers compliant with both Clean Air Act amendment phases."

"RJM Corporation achieved 50% reduction in opacity while reducing NOx by 36%."

"Our existing 1977 burner did not have the turn-down capability to meet our varying steam loads. Other companies wanted to replace the whole boiler, while RJM Corporation designed a high turn down,low emissions, dual fuel burner that sits in the existing boiler wind box. RJM's approach was less expensive, less labor intensive and requires less parts changing. Since the burner retrofit, we haven't had a problem. In fact, we have more control over the flame and the boiler is more functional now. Our emissions are perfect, well in compliance. Their field engineer also was very responsive. RJM did everything they said they were going to do and the whole process went pretty smoothly."

"Our 21-year-old natural gas-fired boiler was in compliance but we needed to bring the efficiency up. RJM Corporation's initial modeling analysis of the boiler determined that there was the proper airflow to the burners. However a burner modification was needed to increase efficiency. The equipment was installed in May 1999 and since then it has been working fine; we're exceeding our efficiency. This was not a complicated job — the proper engineering and know-how was needed. It's simple — what RJM Corporation said they would do they did — they came in and did it!"

"Under Texas' NOx RACT rule, we had a deadline of November 1999 to be in compliance with our gas fired boiler. The limit for boiler #3 was 0.2 pounds per million Btu (lbs/mmbtu) NOx. RJM Corporation's technological CFD modeling appealed to me because it lets you see what is happening in the combustion chamber of the boiler. We determined this approach was better and less expensive than a burner replacement and much less expensive than "end-of-pipe" treatments. In addition to the customized equipment, RJM provided a technical advisor on site to help with the recent installation. Preliminary testing shows levels are below 0.15 lbs/mmbtu NOx and we expect averages to be even lower. Everybody is very happy at this point!"

"With all burners in service, NOx emissions of 0.24 lb/mmBtu are achieved without the use of overfire air at 607 MW. This equates to a 50% improvement over the baseline NOx emissions of 0.48 lb/mmBtu."
