This white paper focuses mainly on challenges and solutions related to fouling and sootcleaning for recovery boilers at chemical pulp mills. The black liquor recovery boiler is so integral today that, without it, most pulp mills would have to shut down operations due to high chemical and electricity costs. In the first chapter, we will present common fouling challenges, and how inefficient sootblower operation can consume unnecessary steam. In the second chapter, solutions to these challenges will be presented.

When reading this white paper, you will learn:

• A clear description of the common fouling challenges and how to handle them
• Examples of solutions for increasing the efficiency of the recovery boilers
• Examples of solutions resulting in more sustainable power production
• Results obtained when upgrading sootblowing systems
