Canada’s industrial sector is a beacon of innovation, and leading this transformative journey is Anssum. With its latest project, the “Recovery Boiler Combustion Optimisation,” initiated in Canada from 01/03/2023 and currently in progress, Anssum aims to redefine the standards of boiler efficiency through accurate ratio control.

Project Overview

  • Category: Energy
  • Location: Canada
  • Project: Recovery Boiler Combustion Optimisation
  • Duration: 01/03/2023 – Present
  • Status: In Progress


Recovery boilers play a pivotal role in the pulp and paper industry, converting black liquor from the digester into steam while recovering chemicals for reuse. The efficiency of these boilers is paramount, not only for energy conservation but also for optimal chemical recovery. One of the primary factors influencing this efficiency is the precision of combustion.

The Challenge

  • Achieve optimal combustion in the recovery boiler.
  • Ensure a consistent and accurate fuel-to-air ratio for combustion.
  • Minimise emissions and wastage while maximising boiler efficiency.

Anssum's Groundbreaking Approach

To address these challenges, Anssum employed a systematic strategy:

  • Advanced Sensors: Integrating high-tech sensors to continuously monitor the fuel-to-air ratio in real-time, ensuring that any deviations are instantly detected.
  • Dynamic Ratio Control: Developing advanced control algorithms that dynamically adjust the fuel and air supply, maintaining an optimal ratio for combustion. This not only ensures efficient combustion but also reduces emissions.
  • Data Analytics: Harnessing the power of data analytics to analyse combustion patterns, identifying areas of improvement, and predicting potential issues before they arise.

Anticipated Outcomes

  • Enhanced Boiler Efficiency: By ensuring accurate ratio control, the recovery boiler will operate at peak efficiency, leading to significant energy savings.
  • Reduced Emissions: Optimal combustion will result in reduced emissions, contributing to a cleaner environment.
  • Sustainable Chemical Recovery: By optimising combustion, the recovery of chemicals will be more efficient, leading to sustainable operations and reduced wastage.


The “Recovery Boiler Combustion Optimisation” project is a testament to Anssum’s commitment to pushing the boundaries of industrial efficiency. By merging technology with practical applications, Anssum is not only enhancing operational standards but also paving the way for a sustainable and energy-efficient future.

With such initiatives, industries can look forward to a future where energy conservation is not just a goal but a standard operational practice.
