General info
Sootblow more, with less steam
More than 90% of the cleaning by a sootblower takes place during the sootblower’s initial stroke.
When the sootblower is retracted, 50% of the steam is used unnecessarily while the soft ash is sintered into concrete-like deposits.
With HISS® (High Impact Sootblowing System), several sootblowers can be operated in parallel with or without return steam, i.e. more sootblowing, less steam, more easily removed ash.

About HISS
HISS transforms your steam sootblowing system
The patented HISS® technology transforms your steam sootblowing system into an effective tool that handles clogging and increases the efficiency of your power and recovery boilers.
- Halve your steam consumption
- Increase your production of electricity
- Double your sootblowing power
- Use cheaper fuel
Works on all soot blower valves/brands. Rosink, Clyde Bergemann, Diamond Power etc.
New: Multi-position Actuator
Three positions. One retrofit.
Direct valve control that maintains Cooling Steam Flow in hot sections and switches to Full Cleaning Flow on demand—without replacing your existing mechanisms. Expect smoother runs, cleaner surfaces, reduced tube erosion due to condensate, and fewer surprises.
- Prevent problems arising from worn out valve opening mechanism
- Increase lifetime of lance and packing gland
- Lowers steam valve wear
- Increases boiler availability
Piloted at a Swedish paper mill.
Key facts
100% increase
In sootblowing capacity, without installing new sootblowers, or consuming more steam.
45 % reduction
In steam consumption, per sootblower.
Beyond technical specification
One year process follow-up increases boiler availability and efficiency

Case studies from HISS installations
Mölndal Energi Sweden
A case study and results from our HISS installation on a biomass boiler at Riskullaverket. Before HISS was installed, soot blowing was employed twice per day and each soot blowing cycle meant 1 MW decrease on turbine load for 2.5 h (duration of one soot blowing cycle).
