ABSTRACT:
Inner and outer welded steel protective tanks are separated by a space containing a granular insulating material such as perlite preventing excessive heating of fuel in a storage space in the inner tank, even when there is a fire at the site. The inner tank may be subdivided into portions by a partition defining a storage space and an overfill containment space receiving overflow from the storage space portion, with a sensor detecting overflow. The overflow containment space is also arranged to collect separated fuel when the tank system is used with a vapor recovery system. The granular insulating material acts as an explosion suppressant by dissipating heat and fuel vapors which may be present in the insulation space as a result of leakage from the inner tank. A triple walled tank of increased reliability against spills and penetration resistance is provided by a two closely spaced inner tanks within the insulation. Insulated tank saddles provide fire protection for the tank support.
