Ensuring flow of bulk materials by using a system of Myrlen® air pulse nozzles. It belongs among very efficient technical solutions of ensuring the flow of bulk materials in silos and hoppers. So called "dead" zones, the formation of chimneys, funnels and bridges can be generally encountered in all vessels and silos of bulk materials. The application of the system of Myrlen® air pulse nozzles resolves problems, if any, with non-flowing bulk materials in vessels, conduits, pours and in other follow-up transport technologies. From practical life, we can mention our experience from ensuring the flow of lignite with up to 55% of relative humidity. We use different mounting systems to pulse nozzle for assembly. Pulse nozzles can use in Potentially Explosive Atmospheres – FTZÚ 15 ATEX 0129.
