THE TECHNOLOGY

KRR employs unique, patented state-of-the-art technology developed in Switzerland to achieve unparalleled boiler cleaning results. The technology is proven and safe and is used worldwide with no adverse incidents reported anywhere.

1. A lance is introduced into the boiler near the area to be cleaned.
2. At the end of the lance a balloon is inflated with an explosive gas mixture.
3. The mixture is ignited via a remote ignition on the control panel.
4. The resulting combustion creates a shock wave which causes vibrations in the boiler wall and pipe bundles. It is these vibrations, along with the shock wave, that dislodges the ash.

Where can it be used?
Our cleaning technology is used in waste to energy and power generation plants and can be applied in:

• Furnace
• Radiation part
• Evaporator
• Superheater
• Economiser
• Air pollution control systems (APC)
• Silos for ash storage

Offline cleaning before inspection and maintenance means that boilers, silos and APC systems can be cleaned efficiently, safely and cost effectively.

Technical requirements
Boiler/vessel openings
To reach the areas to be cleaned, boiler openings must be a minimum 100mm ND

Access requirements
In front of each opening there must be sufficient space for handling the cleaning lance.

Connections required
Pressurised Air (4-8 bar)Water (4-8 bar)Power: 110 volts

Cleaning interval
Depending on the boiler design, waste composition and operating conditions, boilers should be cleaned between 4 weeks and 6 months.
