Nitrogen Inerting System for Biomass Storage
Wood Pellet Storage
Nitrogen Inerting
Fighting a silo fire once it has begun presents multiple challenges, so the preferred measures taken are preventative approaches, such as proactively inerting storage silos with dry nitrogen. The migration of smoldering pellets will be reduced by a continuous inert nitrogen purge. Limiting oxygen concentration of the biomass protects the silo and its contents. A penetrative approach can also include purging with an inert nitrogen gas during the filling and emptying steps.
Condition the Biomass Before Storage
Moisture on the surface of the biomass can be reduced by dry nitrogen gas. This helps to curtail biological activity at the same time as cooling the biomass to lower the chemical oxidation rate. A lower oxygen concentration is created by providing a continuous purge of dry nitrogen gas into the silo which reduces the risk of an explosive atmosphere forming in the headspace.
