Maximise plant availability and MWe output with RJM’s IMPULSE® technology
The RJM IMPULSE® Cleaning System is a sophisticated development of shockwave boiler cleaning technology. It generates rapidly pulsing, powerful supersonic shockwaves to dislodge material build-up on boiler surfaces.
Unlike conventional cleaning methods, IMPULSE® operates as a non-line-of-sight system. The pulse waves wrap around tubes and reach deep into complex geometries, removing stubborn deposits without the erosive damage associated with steam soot blowers.
With over 391 units installed across 77 power plants globally, IMPULSE® is the proven choice for utility, Energy from Waste (EfW), and biomass operators looking to extend generation campaigns and reduce maintenance overheads.
Superior Cleaning Coverage – IMPULSE fires multiple supersonic shockwaves during each activation, typically 20 shockwaves in ten seconds, resulting in highly effective, pro-active cleaning
Low Operational Costs – Simple design with few moving parts, the system requires minimal maintenance and has a significantly lower OPEX than other shockwave systems.
Ease of Installation and retrofit – The compact, self-contained design allows for easy retrofitting on existing boilers with minimal structural modifications required and does not protrude into access gangways.
Zero Tube Erosion – when replacing soot blowers, eliminating high-pressure steam and water, IMPULSE® removes the risk of tube thinning and erosion, significantly extending the lifecycle of the plant’s heat transfer surfaces.
Increased Exported Power – The system does not scavenge plant steam. This allows 100% of generated steam to be directed to the turbine, directly increasing the plant’s net MWe output and revenue.
In 2024, RJM installed eleven IMPULSE® units at a waste wood gasification plant in the UK, followed by a further five units in 2025. The results delivered a step-change in operational performance:
1 MWe increase in net power output
5% improvement in gasifier availability
19 additional days of generation per annum
Record-breaking run of 140 continuous days of operation
Address the root causes of slagging and fouling with RJM’s bespoke engineering. From combustion solutions to IMPULSE® cleaning, RJM provides integrated solutions that extend generation campaigns, maximise MWe output, and reduce the need for manual cleaning interventions.
The IMPULSE® Cleaning System is a development of the pulse detonation propulsion technology pioneered by GE. It uses a pulsed supersonic shock wave, created by the detonation of a mixture of fuel and air, to dislodge material that has built up on surfaces within the boiler.
Evaluate the operational advantages of IMPULSE® over high-maintenance shock pulse systems. This comparison highlights how our pulse-combustion technology delivers more consistent cleaning performance with significantly lower operating costs and reduced mechanical wear on your plant.
