Advanced Boiler Cleaning for Efficiency, Safety & Sustainability

Automated impulse solutions remove ash, slag, and fouling from deposit-prone boiler areas while the boiler remains in operation — a high-impact alternative to manual cleaning, steam sootblowing, and combustion-shock systems, at a fraction of the CAPEX.

Compressed air only: no on-board combustion, ignition, fuel handling, or steam supply. Millisecond shock action and high-velocity airflow target tough fouling without continuous mechanical contact — and repeated pulses fatigue the fouling bond.

Furnace Walls (Radiation Zone)

The Retractable Hybrid AirMace™ nozzle extends into the boiler only during cleaning, fires a powerful air-water blast, then retracts to protect the tip from extreme heat. Fine water flashes into steam, creating secondary pressure waves that break and release deposits.

  • 360° effective cleaning area
  • Nozzle protected when idle, powerful when active
  • Serviceable from outside the boiler
  • More impact, less water, less complexity

Superheaters & Reheaters

Frequent, targeted cleaning with very short high-peak pulses. Pulse series can be fired every few seconds during a cleaning cycle, with power tuned to the application instead of over-stressing equipment.

  • Working pressure 20–300 bar (300–5,000 psi)
  • Adjustable pressure and firing rate
  • Both shock wave and momentum

Economizers

Deposit removal in gas-path sections keeps heat-transfer surfaces clean and thermal efficiency high — without taking the boiler offline or entering confined spaces.

  • Online cleaning during operation
  • Fully automatic, local or remote control
  • 100,000+ fires expected maintenance interval

Tube Banks & Convection Sections

Repeated high-pressure impulses clean tube banks and convection passes where ash and slag accumulate, restoring gas flow and heat transfer across the section.

  • Millisecond shock action
  • Cyclic loading fatigues the fouling bond
  • No continuous mechanical contact

Ash Hoppers & Hopper Inlets

AirMace™ air cannons prevent and clear ash buildup and blockage in hoppers and hopper inlets — operating from standard plant air up to 600 psi with an optional booster.

  • 60–600 psi operating range
  • Optional booster doubles plant pressure
  • Robust valve for dusty environments

Boiler Passes, Ducts & Gas-Flow Paths

Deposit removal in ducts, turns, and restricted gas passages — and other deposit-prone boiler areas with ash, slag, or fouling buildup along the gas path.

  • Compact installation in existing facilities
  • Adjustable pressure, pulse count, and cycle length
  • Air-only or air-water configurations
