Abstract
A container for the above-ground storage of flammable fuels has an inner tank which may be rectangular, with a bottom surface, side surfaces, and a top surface, or which may be some other shape, such as cylindrical, placed within an outer shell having a similar shape. In the case of a rectangular inner tank and a rectangular outer shell, the bottom surfaces of the inner tank and outer shell are spaced apart from each other by first bottom spacers which connect the two bottom surfaces. The side walls of the inner tank and outer shell are also spaced apart from each other by second side spacers which connect the tank and shell. The side spacers for connecting the tank and shell prevent the inner tank from floating within the outer shell when an insulating material, such as concrete, is added therebetween. The inner tank may be constructed of metal, fiberglass, fiberglass-coated metal, polyethylene, or other like materials, while the outer shell is steel.
