These hazards are quickly transported along production through conveying systems and can ignite combustible dust, causing fires and explosions. GreCon Spark Detection and Extinguishing Sys-tems are a cost-effective preventative system, which detects sparks and em-bers, then activates countermeasures before they can cause fire or dust explo-sions. GreCon Spark Detection Systems Advanced Cyclone Systems (ACS) is a company exclusively dedicated to the development and commercialization of high efficiency cyclone systems world-wide.Thanks to its superior efficiency, ACS cyclones are a viable alternative to ESPs and Bag Fil-ters for emission limit compliance in both biomass dryers and boilers. Hurricane cyclones are able to capture very fine dust with a Volume Median Diameter (VMD) Rembe has the expertise as an innovator of flameless venting for indoor/outdoor explosion protection (Q-Box/ Q-Rohr); a comprehensive line of Rembe explosion panels and TARGO-VENT that can help manage precious outdoor space utiliza-tion by reducing safety zones without compromising safety; and Q-Flap NX and EXKOP isolation sys-tems to pre-vent explosion propagation.

We’ve rounded up the top maintenance tips for spark detection and extinguishing systems, as well as mechanical dust collectors, courtesy of GreCon and ProcessBarron. Spark detection and extinguishing systems: • Check the spray nozzles for excessive wear, material build-up and proper operation. • The Y-strainer screen should be flushed clean on a regular basis and replaced if needed. • During months in the freezing weather, ensure heat tape and insulation is installed and working properly to avoid any pipes freezing. • After maintenance, ensure any supply ball valve that was closed for maintenance is then opened for normal operations. Mechanical dust collector: • Yearly casing inspection and cleaning: This includes evaluating the condition of all of the tube assembly parts for possible replacement. Every inlet/ outlet tube should be free of any plugging. Guide vanes are the most common wear item and each one should be reviewed. Any inlet/outlet tubes with holes must be replaced. Any holes in the tubesheets or casing must be patched, as the dirty and clean compartments must be kept airtight and separate. Make notes on any material build-up in a particular area or unusual wear patterns. • Yearly hopper inspection and cleaning: This includes looking for evidence of fires and verifying no clinker build-up. Holes in the sidewalls must be patched and cracks in the welds must be repaired. Every time the access door is opened, the seal gasket material must be replaced. If a poke hole opening is present it must always be capped off and sealed while the unit SUMMER 2019 24 Canadian BIOMASS
