What Combustion and Emissions Solutions Does RJM International Offer for Different Generation Assets?

Updated

RJM International provides engineering-based upgrades for four generation asset types: gas, Energy from Waste (EfW), biomass, and coal. Each offer is framed around a specific plant problem — emissions compliance, efficiency loss, fouling, or fuel transition — rather than a single product line. The right fit depends on your fuel, your compliance target, and whether you are converting, co-firing, or optimising an existing unit.

Gas: Coal-to-Gas Conversions and Ultra-Low Emission Burners

For gas-fired and converted assets, RJM lists two core offers:

  • Coal-to-gas conversions — for utilities moving a unit off coal while retaining the existing generation asset.
  • Ultra-low emission burners — the emissions-compliance route for gas applications.
  • Multi-fuel options, including hydrogen — relevant if you need fuel flexibility beyond natural gas.

These are described as tailored to any utility or industrial application. If your driver is a NOx limit or a fuel-switch mandate, this is the relevant section of the portfolio.

Energy from Waste: Efficiency, Reliability, and Output

RJM's EfW offer is framed as four outcome areas:

Outcome What it means in practice
Improved efficiency More useful energy per unit of waste processed
Better reliability Fewer unplanned interruptions to the waste-processing chain
More MWe output Additional electrical export from the same plant
Lower emissions Compliance with tightening emissions limits

EfW plants face a particular constraint: waste intake cannot easily be paused, so reliability improvements carry operational value beyond the generation side.

Biomass: Tackling Slagging and Fouling

Biomass firing brings fuel-quality variability that shows up as deposit build-up on heat transfer surfaces. RJM's biomass offer targets exactly that:

  • Less slagging and fouling — the primary cause of efficiency drift and forced outages in biomass units.
  • Improved utilisation and reliability — more available hours per year.
  • Longer campaigns — extended running periods between cleaning.
  • Shorter outages — reduced cleaning and maintenance duration when stops do occur.

The IMPULSE® cleaning technology (described below) is the mechanism most directly linked to the fouling claim.

Coal: Burners, Conversions, and Co-Firing

Coal assets get the broadest set of options, reflecting the range of transition pathways available:

  • Ultra-low emission burners — emissions reduction without changing fuel.
  • Coal-to-gas conversions — full fuel switch.
  • Coal-to-biomass conversions — full fuel switch to a renewable feedstock.
  • Co-firing with biomass — partial substitution, retaining coal capability.

The choice between these is a function of your compliance timeline, fuel supply chain, and how much of the existing boiler and handling equipment you intend to retain. RJM presents these as engineering-based upgrades to "every generation asset," implying site-specific design rather than off-the-shelf retrofit kits.

IMPULSE®: The Cross-Cutting Cleaning Technology

IMPULSE® appears as a standalone offer applicable across boiler types. Its stated benefits:

  • Improved boiler efficiency
  • Significantly reduced fouling
  • No erosion
  • Better coverage
  • Proven technology

Because fouling affects biomass and EfW plants most acutely, IMPULSE® is the offer most likely to be relevant regardless of which fuel category you sit in — it addresses the efficiency loss mechanism rather than the fuel itself.

How to Choose Between These Offers

Use the following conditions to narrow the list:

  • Facing a NOx limit but keeping your fuel → ultra-low emission burners.
  • Mandated or economically driven fuel switch → coal-to-gas or coal-to-biomass conversion.
  • Partial transition with supply uncertainty → co-firing with biomass.
  • Efficiency declining between cleans, or frequent fouling-driven outages → IMPULSE® cleaning, particularly for biomass and EfW.
  • Need hydrogen capability or multi-fuel operation → the multi-fuel option within the gas portfolio.

RJM states its solutions are backed by guaranteed efficiency and emissions compliance, and directs prospective clients to contact its engineering team directly — the site does not publish pricing, so scoping and cost require an enquiry.

What the Company Background Adds

RJM holds The King's Award for Enterprise: International Trade 2026 and was named Winchester Sustainable Business of the Year in 2026. Its published technical position is that NOx management "starts before NOx is formed" and should be approached at whole-plant level rather than component by component — useful context for interpreting why the offers above are grouped by asset type rather than sold as isolated equipment.
