FIRE PREVENTION IN STORAGE SILOS

摘要

Apparatus and method for preventing and extinguishing fires in storage silos containing flammable materials, especially biomass. A liquid carbon dioxide storage vessel has a liquid outlet supplying at least two flow paths. At least one of the flow paths supplies gaseous carbon dioxide to a storage silo for controlling smouldering fires, and the at least one other flow path supplies carbon dioxide vapour and carbon dioxide snow to the storage silo for fire extinguishing. The liquid carbon dioxide vessel may be arranged to supply gaseous and liquid carbon dioxide to more than one storage silo.

主权项

1. An apparatus for preventing and extinguishing fires in silos containing flammable materials, the apparatus comprising:
a storage vessel for storing liquid carbon dioxide, the storage vessel having a liquid outlet; a first flow path extending from the liquid outlet to a first net into the headspace of a silo; and a second flow path extending from the liquid outlet to a second net into the headspace of the silo; wherein the first flow path is arranged to supply substantially gaseous carbon dioxide to the headspace of the silo via the first inlet, and wherein the second flow path is arranged to supply substantially liquid carbon dioxide to the second inlet, wherein the second net is arranged so that, in use, the liquid carbon dioxide expands to carbon dioxide vapour and carbon dioxide snow substantially on entry into the headspace of the silo.
