Rotary drum dryers remain the most common—and most practical—drying technology in Canadian pellet plants. They are robust, heat-efficient and responsive to changes in feed moisture. At the same time, incident history across the sector shows a recurring reality: when a dryer incident occurs, it rarely involves only the drum. It can involve the entire integrated line, from the furnace and dilution duct to the drum and cyclones and through the induced-draft fan and quench interface. To help the industry reduce fires and explosions in rotary drum dryers, the Wood Pellet Association of Canada (WPAC) has released a Safer Operations of Rotary Drum Dryers report. The report was developed by a multi-stakeholder Rotary Drum Dryer Working Group tasked with consolidating lessons from incident reviews and bowtie analysis into practical expectations for safer, verifiable operation—what “good” looks like when the process is under stress, not just when it is steady.
