The patented HISS technology, originally developed by the company SootTech, 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 you production of electricity
• Double your sootblowing power
• Use cheaper fuel
Increased sootblowing frequency
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 Soot System), several sootblowers are operated in parallel with or without return steam, i.e. more sootblowing, less steam, more easily removed ash.
Examples of increased power and steam savings of 68% with HISS.
Increased power and steam savings
With rising electricity prices, it is important for the recovery boiler to generate as much electricity as possible.
The efficiency of the economizer surfaces directly affects the volume of high-quality steam energy produced at the same time as sootblowing is often shifted away from economizers due to clogging earlier in the flue gas direction.
With SootTech’s HISS technology, it is easy to increase heat absorption in MW levels by cleaning the economizer surfaces more effectively without any increase in soot steam consumption or volume of flue gas.
In HISS electricity mode, it is a simple matter to redistribute sootblowing and directly increase electricity production in megawatts when electricity prices are high.
Faulty runs and periods of very large carry-over are not unusual. These “periods” often result in permanent deposits that cannot be removed by means of sootblowing.
The best way of dealing with carry-over is to sootblow much more frequently so that the ash does not have time to sinter.
With SootTech‘s CarryOverMode, sootblowing can be focused with the press of a button to the front section of the boiler and performed e.g. 3-5 times more frequently than normal.
SootTech‘s CarryOverMode, together with HISS technology, means that you are less likely to suffer from operating errirs since you then have the tools to effectively deal with the consequences.
