EnglishWhat Is RJM International's IMPULSE® Technology Used For?
Updated
IMPULSE® is RJM International's boiler-cleaning technology, used to keep boiler heating surfaces clean so that efficiency is maintained and fouling is significantly reduced. According to RJM's own product listing, it is aimed at improved boiler efficiency, significantly reduced fouling, no erosion, better coverage, and is described as proven technology. It sits within RJM's wider set of engineering solutions for upgrading generation assets across gas, Energy from Waste, biomass, and coal plants.
The problem it addresses
Boilers accumulate deposits on their heat-transfer surfaces as they run. Left in place, that fouling insulates the surfaces, so heat passes less effectively into the working fluid and boiler efficiency falls. The practical consequences plant operators typically watch for are:
- Higher fuel use for the same output
- Reduced reliability and more unplanned interventions
- Shorter runs between cleaning outages
RJM positions IMPULSE® directly against these effects: cleaning that improves boiler efficiency and significantly reduces fouling.
What the technology is used for
Based on RJM's published description, IMPULSE® is used for:
| Use | What it means in practice |
|---|---|
| Boiler cleaning | Removing or limiting deposits on boiler surfaces so heat transfer stays effective |
| Efficiency improvement | Recovering boiler efficiency that fouling would otherwise erode |
| Fouling reduction | Significantly reduced fouling as a stated outcome |
| Coverage | Better coverage of the surfaces being cleaned |
| Erosion control | Cleaning without erosion of the boiler surfaces |
The "no erosion" and "better coverage" points are the two claims that distinguish it from cleaning approaches that are abrasive or that miss areas of the boiler. RJM presents both as characteristics of the technology rather than as options.
Where it fits in a plant
IMPULSE® is listed alongside RJM's other asset-specific solutions rather than as a standalone product line. In RJM's own framing, it appears under a general heading of engineering-based solutions to upgrade every generation asset, next to:
- Gas — utility coal-to-gas conversions, ultra-low emission burners, multi-fuel options including hydrogen
- Energy from Waste — improved efficiency, better reliability, more MWe output, lower emissions
- Biomass — less slagging and fouling, improved utilisation and reliability, longer campaigns, shorter outages
- Coal — improved performance, ultra-low emission burners, coal-to-gas and coal-to-biomass conversions, co-firing with biomass
That placement matters: for biomass plants in particular, RJM explicitly lists "less slagging and fouling" and "longer campaigns" as outcomes, which is the same territory IMPULSE® addresses. If you are operating a biomass or waste-to-energy boiler where deposit build-up limits run length, IMPULSE® is the relevant RJM offering to raise with their engineering team.
How to decide whether to pursue it
RJM's site does not publish specifications, performance figures, pricing, or commercial terms for IMPULSE®, so treat the listed benefits as vendor claims to be verified against your own boiler. Before contacting them, it helps to have:
- Your fuel and boiler type — biomass, EfW, coal, or gas, since RJM's solutions are organised by these categories.
- Evidence of the fouling problem — efficiency trends, exit-gas temperatures, or outage records showing deposit-related losses.
- Your constraint — whether the issue is efficiency, run length between cleans, or surface erosion from existing cleaning methods.
RJM's site directs enquiries to its engineering team via a contact form ("Talk to our engineering team today"). Because IMPULSE® is described as proven technology with named benefits but no published data, the useful next step is to ask RJM for references in your sector and for the basis of the efficiency, fouling, and erosion claims.
What it is not
IMPULSE® is a cleaning technology, not an emissions-control device. RJM's emissions work — ultra-low NOx burners, coal-to-gas conversion, hydrogen and multi-fuel options — is presented separately. If your goal is NOx compliance rather than boiler efficiency and fouling, the burner and fuel-conversion solutions are the relevant part of RJM's portfolio; IMPULSE® supports efficiency and availability, which is a different objective.
