Patent Issued to R.F. MacDonald Co. for NOx Emissions Reduction Technology
With the help of Michael MacDonald and the Boiler Special Projects Group, R.F. MacDonald Co. has invented and now patented the safest NOx emissions reduction process for boilers and fired vessels using direct urea injection with SCR.
On Tuesday, Nov. 24, 2020, the U.S. Patent and Trademark Office issued the safest and simplest NOx-reduction process patent for packaged boilers. The patent was granted to R.F. MacDonald Co. for inventing a “process for direct urea injection with selective catalytic reduction (SCR) for NOx reduction in hot gas streams and related systems and assemblies.”
SCR requires the use and storage of ammonia-based reagents, which range from high risk to low risk. The R.F. MacDonald Co. patent specifies urea, which is the lowest risk ammonia-based reagent. The only health hazard associated with urea is “possible irritation” as indicated by the Hazardous Materials Identification System (HMIS). The urea solution is identical to Diesel Exhaust Fluid (DEF), which is sold worldwide in automotive retail stores for use in diesel motor vehicles.
As shown in the graphic below, urea is injected at each Injection Point into the boiler. As NOx and urea pass through the NOx Reduction Catalyst, NOx is separated into two non-harmful elements Nitrogen (N2) and water (H2O). Read More

History and Founder
An objective for all of us in life is to potentially leave a part of ourselves as we depart this life for another. There are many adjectives that can be used to describe our founder Bob MacDonald but perhaps none more appropriate than ‘persistent.’
From Bob’s personal desk to the growth of our ten-office company, and ultimately his fight with cancer, persistence was his unwavering theme. In the memory of our founder, may these words by Calvin Coolidge be an inspiration to you.
Persistence – A Quote by Calvin Coolidge
Nothing in the world
can take the place of persistence.
Talent will not;
nothing is more common than
unsuccessful men with talent.
Genius will not;
unrewarded genius is almost a proverb.
Education will not;
The world is full of educated derelicts.
Persistence and determination
alone are omnipotent.
The slogan ‘Press On’ has solved
and always will solve
the problems of
the human race.

Boiler Tech Makes Himself Available on Short Notice, Successfully Repairs Linkage Issue During Boiler Source Test, and Stays During Test Monitoring in Case Issues Occur
Stationary Engineer, Wastewater, Northern CA
I wanted to take a few moments to thank you for taking care of us once again this year. I also want to mention how pleased we were with the work performed by Brad. He was thorough and was able to correct any issue encountered. To top things off, we were extremely impressed that during our source test we had an issue with the linkage to one of our gas valves causing us to be out of compliance. I made a single phone call, and you were able to redirect Brad to us immediately. Thanks to your quick response, we didn’t have to reschedule our source testing. Brad was able to identify and correct the issue quickly, and he stayed onsite for the duration of the test monitoring of the flue gas in case any other problems arose. Due to the excellent customer service you have provided us these last two years we are happy to say that R.F. MacDonald has earned our business for as long as we continue to have steam boilers.
RFMCO Crews Are Safety-Focused, Respectful, Pleasant to Work with and Skilled at Their Trade
Project Engineer, Food Processing, Central Valley
The demo crew that got rid of the old boilers did a fantastic job! The area looks great! They even took the time to hose down before leaving! That was a nice touch — thoughtful and professional! Wes called when they were finished to give me a heads-up about the demoed piping that couldn’t fit in the recycle bin. Now that we have more open floor space, I’ll bet Facilities will make plans for new equipment. I just wanted to jot down these sentiments because the crews on the demo and the install deserve the feedback. Rest assured the boilers are running well with no related production issue, the old area looks new again, and I am very pleased with the way the RFM project crews were safety-focused, respectful, pleasant to work with and skilled at their trade.
RFMCO Ensures Inspection and Certification Approvals by Showing ‘Trade Knowledge, Professionalism, Pre-Planning and Coordination’
Quality Control Manager, Contractor, Southern CA
Richard played an integral part in getting these boilers through startup and tests/inspections. Pierre, our boiler inspector, wasn’t confident in our ability until he heard Richard was tasked with starting up the boiler. After Pierre’s inspection, he sent us the below “Atta Boy,” which I would like to extend to Richard: ‘I want to extend my appreciation for the outstanding support and team effort in preparing for BUPV inspection and certification of NR4 Plant.’ Without Richard's trade knowledge, professionalism, pre-planning, and coordination, I don’t think I could’ve made it through Pierre’s Inspection successfully.

A few key points I continue to see from your team are: professionalism by management and team, detailed communication from start to finish during working and non-working hours, never explaining issues but always having a solution to fix them immediately and HARD Work Period.

Boiler Techs Make ‘Rock Solid’ Repairs and Technical Adjustments to Heat Swimming Pool During Winter Months
Facilities Supervisor, University, Southern CA
I want to take a moment to thank you and your team for the recent repairs you made to the University swimming pool heating system. Due to supply issues, your team was able to get only one of the heaters running. Although I was thankful, I remained concerned because the contractor who installed the heaters in 2013 told me one heater would not be sufficient to heat the pool during the winter months. But, ever since your technicians made the needed repairs and made technical adjustments, the pool heating system has never worked so well! It has been "rock solid" for over a week now!
Boiler Parts Experts Work Tirelessly to Find Obsolete Parts and Respond Quickly to Facility Emergency

Outside of this recent work, I know R.F. has always been responsive when we have emergencies, and your guys stay involved until the job is done. It’s nice to have that reassurance that you aren’t just a contractor but also a partner with us on these repairs.
