Corporate history

RJM Corporation was founded in Connecticut in 1977 by Richard J Munro, with the business focused on offering R&D consulting services to the thermal-fired power generation sector.

RJM quickly established a name for itself as a company which could design and implement modifications that yielded significant improvements in terms of both operational efficiencies and reduced emissions.

From the 1990s, Richard helped pioneer the use of CFD for industrial combustion.  He successfully applied CFD analysis to all makes and models of burners and boilers, consistently delivering exceptional results, no matter what the fuel or the firing configuration.

RJM's expertise was such that it could also achieve further emissions reductions from existing 'low NOx' burners. Consequently, RJM soon built up a substantial reference portfolio of RJM-modified generation plants throughout North America. Key customers included Exelon, Entergy, TXU, FirstEnergy and Duke.

The company also began taking on overseas projects and in 2000, to consolidate growth outside the USA, set up a European subsidiary with headquarters in the UK.

In 2004, RJM Corporation ceased trading in the USA, when the founder decided to pursue other interests outside the power generation sector.

RJM's European managers were keen to continue to grow the business and set the wheels in motion for a management buy-out. This was completed in 2005 and the company was relaunched as RJM International.

Focusing initially on opportunities in the UK and Europe, RJM International more than doubled its turnover in 2005 and did so again in 2006.

Since that time, RJM has built up a strong team of skilled personnel and has continued to expand year on year, improving its service offer and widening its portfolio of RJM-designed and manufactured products, ranging from small replacement components for oil light-up equipment to complete sets of RJM's own Ultra-Low NOx Burners; suitable for coal, oil, gas or biomass-fired boilers.

Since the mid-1990s, RJM has completed over 60,000MWe of major combustion and emission control projects at global power generators and other large combustion plants throughout the world.

In 2011, RJM International consolidated its relationship with SAS, Inc. a Tulsa-based company that provided additional CFD resources to RJM, through the establishment of a joint venture.

In 2018, a new US-based subsidiary of RJM International was established and the assets of SAS, Inc. and its personnel were brought into the new RJM USA business, based in Tulsa, OK.

Some of RJM International's most recent successes include:

2018 Tulsa, USA RJM returns to the USA and establishes a new regional office based in Tulsa, OK. 

2018 Singapore RJM establishes Asia-Pacific operation with a new regional office in Singapore to target new opportunities in China and throughout the Far East.

2017 UK RJM is awarded The Queen's Award for Enterprise - Innovation 2017 by the UK government. RJM appoints Buka Power as its agent in India.

2016 CHINA RJM completes its first major project in China, with the introduction of nine of its new ultra-low NOx CleanAir BurnersTM retro-fitted to a district heating plant outside Beijing. These burners meet the stringent NOx limits of China's new Clean Air Act and are helping to improve air quaility in the city.

2016 UK RJM awarded BS EN ISO 9001: 2015 Quality Management System Certification.

2015 UK AND WORLDWIDE RJM wins the prestigious Innovation Award from the Energy Insititute. The company also secures addtional new contracts at UK and overseas power plants as the market continues to recognise that RJM can help generators achieve NOx levels below 200mg/Nm3 using primary measures only. RJM completes move into new offices.

2014 UK RJM announces move into larger, prestigious premises in Winchester to better serve its growing customer base and secures major NOx reduction projects from EDF for two of its coal-fired plants in England.

2013 UK AND WORLDWIDE RJM secures contract at SSE Ferrybridge to replace all 48 burners on Unit 4 with its own range of Ultra-Low NOx Burners. This follows on from a similar, sucessfully concluded project on Unit 3 during 2011. Two variants of RJM's own Ultra-Low Nox Biomass Burners now on test at a major UK power plant; an RJM-designed and built gas burner installed on an industrial process plant in China; a waste fuel biomass feasibility study for a power plant in Italy, plus a number of other confidential projects for some of the world's leading power supply and utility companies.
