The energy sector, particularly in industries with large boilers, constantly seeks ways to optimise and enhance their operations. One such endeavor by Anssum in Canada, termed “Recovery Boiler Sootblowing”, epitomises the synergy of smart solutions and efficiency gains.

Project Overview

  • Category: Energy
  • Location: Canada
  • Project: Recovery Boiler Sootblowing
  • Status: Completed


Recovery boilers, critical to various industries, can face challenges with accumulated soot, reducing their thermal efficiency over time. Efficient sootblowing can significantly improve the boiler’s performance, leading to energy savings.

The Challenge

  • Increase the boiler’s thermal efficiency.
  • Implement a sootblowing strategy that’s both effective and economical.

Anssum's Ingenious Solution

Anssum proposed a shift from conventional sootblowing practices to a “smart sootblowing” approach. This method:

  • Optimises the Frequency of Sootblowing: Rather than adhering to a rigid schedule, smart sootblowing adjusts the frequency based on real-time data and boiler conditions.
  • Reduces Wear and Tear: By targeting only areas that need cleaning and reducing unnecessary sootblowing, the lifespan of boiler components can be extended.
  • Maximises Thermal Efficiency: Ensuring that the boiler operates without excessive soot accumulation guarantees optimal heat transfer and overall efficiency.

Outstanding Outcomes

  • Steam Savings: The initiative led to savings of 0.14 klb steam per ton of BL fired, a significant reduction in operational costs.
  • Economic Impact: This efficient sootblowing translated to a monetary saving of $CAD 142k per annum, showcasing the dual benefits of the project – enhanced efficiency and cost savings.


The “Recovery Boiler Sootblowing” project in Canada stands as a testament to Anssum’s commitment to energy conservation and operational efficiency. By integrating smart solutions with traditional practices, Anssum has once again demonstrated its prowess in driving sustainable and economical outcomes for industries.

The future of energy efficiency lies in the harmonisation of traditional practices with innovative technologies. Projects like these pave the way for a more sustainable and cost-effective industrial landscape.
