of global plant improvements
From its origins as a business offering R&D consulting services to the thermal-fired power generation sector in the USA, it is today a global provider of a range of products and services that is enabling the thermal-fuel fired sector to transition successfully to lower carbon, low emission generation.
Some of our 2020 projects include:
Reducing harmful emissions at one of Europe’s most polluting power stations, as part of an EU-funded consortium to improve air quality in Kosovo;
Improving performance at a number of biomass and Energy from Waste sites in the UK to enhance reliability, reduce emissions, maximise MW output and enable them to operate on a wider fuel diet;
Devising a SUFA system to achieve a significant step change reduction in NOx levels, down to 200mg/Nm³ at a power station in Northern Ireland;
Researching and writing a report for a power plant in Chile to facilitate the introduction of co-firing with blue hydrogen to deliver low carbon energy.
Part of RJM’s 3-D ductwork plan to help deliver the NOx reduction project at Kosovo
We are helping to transform the thermal power generation sector to deliver low-emission, low-carbon energy worldwide.
Today, RJM’s primary focus involves working in partnership with some of the world’s leading utility supply companies, other large combustion plants as well as biomass and Waste to Energy facilities. RJM helps them to operate as efficiently and as cost-effectively as possible, whilst meeting the latest emissions regulations relating to SOx, NOx, particulates and carbon.

BSc Chem. E (Hons)
Combustion, emissions and performance improvement expert with over 35 years’ experience in the energy sector managing complex multi-million pound projects.
John Goldring is a highly skilled energy sector professional with over 35 years of technical, commercial and company management experience, providing combustion engineering expertise to the power generation industry worldwide. He has a wide-ranging track record of success in the development and global commercialisation of innovative, ultra-low emissions technologies, products and services for the efficient combustion of coal, gas, oil, biomass and WtE fuels.
John has been Managing Director of RJM International since 2005 and is responsible for managing the business and leading on new revenue generation from utilities, biomass and WtE plants as well as other major industrial customers, worldwide.
In 2000 John established the European office of RJM Corporation to bring the RJM commercial product line and service offer to the global market outside the USA. In 2005 he completed the management buyout of the European arm of RJM Corporation, enabling greater investment into the UK-based business. Prior to joining RJM, John was Managing Director of Todd Combustion (latterly John Zinc) and held senior roles at Credfeld Camtorc.
John presents regularly at energy conferences and is a frequent contributor to international technical publications focusing on combustion improvement, emissions reduction and the development and integration of new, low carbon fuels.
A pioneer developer of unique CFD models to inform the design of ultra-low NOx burner technologies. Holder of numerous patents. Significant theoretical knowledge and hands-on experience in R&D settings, test facilities, field analysis of combustion problems and equipment start-ups.
Larry has been working with RJM since 2008 with a focus on CFD work and prior to that held senior engineering roles at John Zinc and in the United States Navy.
Energy engineering and commercial professional, with over a decade of experience managing multi-million pound EPC retrofit contracts on thermal power plants in the UK and Europe.
Steve joined RJM in 2007 as a Project Engineer and was appointed Project Manager in 2010. As Head of Projects since 2018, Steve is responsible for the successful management of all RJM’s projects outside Asia-Pacific. Today this includes projects running in the UK, Northern Ireland and mainland Europe, ranging from the upgrade (NOx reduction) of two lignite-fired units in Kosovo to performance optimisation programmes for a number of biomass plants in the UK.
Steve was a co-inventor of a unique NOx-reducing Separated Under Fire Air (SUFA) system suitable for T-fired coal boiler applications. This patented technology has now been successfully installed at EPK Kilroot in Northern Ireland.
Steve was also involved in the re-design of a new RJM coal burner for Engie’s power plant at Rugeley. This unit delivered such good performance that it was IED compliant without the need for secondary NOx reduction measures, yielding less than 200mg/Nm3. On this project, he also was responsible for all the commercial and contractual negotiations and managed the project from start to finish.
Engineering Team Manager and experienced combustion engineer with over 30 years’ experience in coal, oil, gas and biomass power generation projects worldwide. Principal areas of technical knowledge include risk analysis and mitigation, fuel analysis, fuel handling and preparation, fuel and boiler safety, Burner Management Systems, flame monitoring and combustion.
Steve is an experienced combustion engineer with over 30 years’ experience in the power generation sector, in equipment design, consultancy and operations support roles. His core areas of technical expertise also include oil, gas and biomass combustion system design and operation.
As well as managing all the new systems and processes that are being developed for the NOx reduction project in Kosovo, Steve is the technical lead for RJM’s long-term contract at the AES – VCM Mong Duong II plant in Vietnam, resolving critical combustion issues impacting on reliability, efficiency and safety. Activities have included site investigation and testing, CFD modelling, equipment design, safety reviews and a full HAZOP of the combustion system and boiler.
Steve joined RJM in 2011 and previously held senior positions at Parsons Brinkerhoff and RWE npower. He has authored and co-authored a number of technical papers on subjects ranging from alternative fuels and ATEX compliance to the impact on flame stability when co-firing coal with biomass.
Dr. Anura Perera
Head of CFD
Specialist CFD modeller with 30 years’ experience in modelling combustion and emissions, focusing on concept development for low emission burners and the application of CFD to resolve complex combustion issues in large industrial and utility boilers.
Anura is one of the UK’s leading CFD modellers with expertise in innovative concept development, problem-solving, troubleshooting and a focus on solutions delivery. Having worked for ANSYS FLUENT (Europe) as a Senior Developer of pollutant models earlier in his career, Anura has an unrivalled understanding of the FLUENT CFD product as it relates to combustion and emissions analysis.Prior to joining RJM in 2017, Anura was Principal CFD Engineer at Doosan-Babcock.
