Boiler Cleaning - Efficient. Safe. Automated.

Boilers and heat exchangers are the heart of industrial energy and production plants. However, during operation, soot, ash, and combustion residues accumulate – efficiency decreases and fuel consumption rises. The solution: reliable, automated and safe boiler cleaning.

With the Shock Pulse method of the SPGr series, we offer a proven technology that combines powerful yet gentle cleaning with maximum operational safety – without water, chemicals, or manual intervention.

Shock Pulse Method

Why is boiler cleaning essential for the efficiency and safety of power plant boilers?
  • Prevents heat exchanger losses
  • Reduces emissions
  • Increases plant availability
  • Minimises unplanned downtime
  • Extends the service life of boiler components

Boiler cleaning is not just a matter of maintenance; it is a key contribution to operational safety, energy efficiency and the economic viability of modern power plants.

Comparison of Common Boiler Cleaning Methods
Technology Cleaning performance Degree of automation Operating Costs Remarks
Shock Pulse (SPGr series) ★★★★☆ Fully automated Low Highly efficient, operated with air-methane mixture
Shower Cleaning ★★☆☆☆ Manual High Corrosion risk, difficult during shutdowns
Water Cannon ★★★☆☆ Semi-automated High Strong mechanical action, potentially invasive
Wall Blower ★★☆☆☆ Semi-automated Medium Localised effect only
Sootblower ★★☆☆☆ Semi-automated Medium Proven, but inefficient against hard deposits
Rotary Sootblower ★★☆☆☆ Fully automated Medium Limited reach, continuous operation
Rapping System ★☆☆☆☆ Fully automated Low For heat exchangers, weak effect
Shot Cleaning System ★☆☆☆☆ Semi-automated Low Requires special geometry, for economisers; high wear
Sonic Cleaning ★☆☆☆☆ Semi-automated Low Only suitable for light deposits
Explosive Cleaning ★★★☆☆ Manual High Risk of micro-cracks or premature material wear, sometimes requires permits or authority approval

FAQ – Frequently Asked Questions about Boiler Cleaning

  • Depending on fuel type and plant load, cleaning of the convection passes may be required every 8 to 12 hours. In the radiation passes (e.g. with shower cleaning), cleaning once per week is often sufficient. With the SPGr series, this can be fully automated.
