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 at the same time as 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.
Key facts
Sootblowing capacity increased by 100% without installing new sootblowers or consuming more steam
Reduced steam consumption by 45% per sootblower
Beyond technical specification – One year process follow-up increases boiler availability and efficiency

Applications
Carry-over tool – VooDoo
VooDoo will assist in pushing the boiler beyond its technical specification by analyzing visual carry-over data. A tool that controls liquor flow and temperature and, when used in conjunction with HISS™, allows for intelligent control and optimization of steam sootblowing. The tool provides an early warning system to prevent plugging in the boiler.
VooDoo is a patent-protected technology developed by the leading innovation and research company Soottech AB and marketed by Heat Management.
Case studies from HISS installations
ENA Energi, Enköping Sweden
In this boiler at ENA Energi, the HISS system is used for being able to operate the steam soot blowers in the superheater more often when combusting more difficult fuel (waste wood)
Kraftvärmeverket Eskilstuna, Eskilstuna Sweden
HISS was installed for being able to soot blowing more often in the superheaters, thereby keeping those parts clean, without consuming more soot blowing steam.
Mölndal Energi Sweden
A case study and results from our HIISS 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).
