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
Paper Mill, Hungary
In 2024, Heat Management partnered with a Hungarian paper mill to support the optimization of their boiler operation. The deployment of HISS® marked a strategic step toward improving cleaning efficiency, extending equipment lifetime, and supporting more stable and cost-effective boiler operation.
Pulp Mill, Sweden
The customer’s Götaverken recovery boiler, commissioned in 1976 and upgraded to 2,600 tDS/day (from 1,900 tDS/day), operates at 350 t/h with sootblowers consuming about 27 t/h (7.5%). To improve efficiency, HISS® technology was implemented in June 2024 to optimize online cleaning, reduce sootblowing steam use, and raise main steam temperature while maintaining high availability.
On-demand Webinar: Improved sustainability strategies for the energy sector
The IPCC report from August 2021 and the results from COP26, making it clear that the energy-producing industry needs to focus even more on reaching its suitability goals. We have to look for new innovative ways not yet pursued.Â
Ahlström-Munksjö Aspa Bruk, Aspabruk Sweden
A case study and report from our HISS installation at Ahlström-Munksjö Aspa Bruk. The goal with the HISS project at Ahlström-Munksjö Aspa Bruk was to run the boiler at maximum load and increase the cleaning effect in the boiler with maintained steam consumption.
