One of the common ways this can be done is through the use of a spark detec-tion and suppression system. “Spark detection and suppression sys-tems are based on detection in the form of an infrared detector, or detectors, de-pending on the duct size, looking for a hot spot, typically a spark or burning ember traveling through a duct or on a convey-or, detecting it, and then, X amount of metres downstream based on conveying velocity, inject a water spray to suppress that burning ember before it gets into the downstream receiving vessel where it might find the right dust-air mix to start an explosion,” Grandaw explains. There are a wide variety of technology suppliers in the dust and spark detection and suppression space, so selecting the right technologies for a plant requires the consideration of multiple factors. “Like with any other technology, there are a number of considerations you have to look at when you put in one of these systems: What is the scale of the detection and protection required? What are your airflow velocities? Is the application out -12 Canadian BIOMASS SUMMER 2025 2025-06-10 10:54 AM CB_ConceptAir_Summer25_CSA.indd 1
