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.
