About Us

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.

Larry has over 40 years’ power and process industry experience and over that time has designed and engineered numerous new combustion products and systems. He has also developed unique analysis methodologies and invented state-of-the-art Computational Fluid Dynamic (CFD) models.With a wide range of practical expertise and theoretical knowledge, Larry’s areas of expertise, as well as CFD, include combustion science across a number of large combustion applications including refinery furnaces, flares and utility boilers. His multiple fuels experience spans gas, refinery fuels, oil, coals, and biomass.

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.

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.

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. Anura is a prolific author of technical papers and has been advancing the understanding of mathematical modelling as applied to the combustion of various fuels in the power generation sector since first being published in 1993.

Gerry has over 36 years’ experience in the power sector, focusing on the engineering, design, construction and commissioning of fossil fuel and biomass-fired large industrial and utility boilers, burners and ancillaries. As RJM’s fuels and combustion expert, he is involved in the engineering design and technical assessment of new and existing projects, as well as combustion system analysis, fuels assessment and advice on all matters relating to combustion system performance. He has a wide experience of fuels and combustion, both on test rigs and at power stations.Gerry is also skilled at practical problem-solving at power stations, no matter what the fuel, and is now applying this experience to biomass and WtE plants in the UK and overseas. Gerry joined RJM in 2014 and prior to that held senior roles at RWE npower, specialising in coal to biomass conversions for utility plant. Gerry is an Executive Member and Division chair for the combustion division of the Fuel and Energy Research Forum.

Roger is RJM’s materials handling, fuels storage, transportation and engineering construction specialist, with over 50 years’ experience in all aspects of the bulk materials handling industry. He is responsible for the assessment, design, manufacture and on-site installation of all new or modified materials handling equipment at customer sites worldwide. For RJM he has re-designed systems and managed the upgrade work on-site at many UK and overseas power stations for fuel, ash and other bulk materials. He is also responsible for designing new storage systems, mechanical and pneumatic conveyors and material flow control systems for coal-to-biomass conversions and in the biomass and WtE segments.
