Abstract
A storage silo apparatus having a storage silo including a shell wall, a secondary wall spaced radially outwards from the shell wall, and a space having a first width formed between an outer surface of the shell wall and an inner surface of the secondary wall. An insulation layer located in the space is narrower than the space such that an air gap is formed within the space. The air gap is formed radially adjacent the insulation layer and is configured to resist heat transfer between the shell wall and the secondary wall.
Claims19
A storage silo apparatus comprising:
- a storage silo having a shell wall having a height;
- a secondary wall spaced radially outwards from the shell wall and surrounding the silo;
- a space having a first width formed between an outer surface of the shell wall and an inner surface of the secondary wall;
- and
- an insulation layer disposed in the space between the secondary wall and the shell wall, the insulation layer having a second width that is smaller than the first width such that the difference between the first width of the space and the second width of the insulation layer forms an air gap within the space,
- wherein the air gap is formed radially adjacent the insulation layer and is configured to resist heat transfer between the shell wall and the secondary wall.
An insulation system for a storage silo having a shell wall, the system comprising:
- a secondary wall configured to surround the silo and to be spaced radially outwards from the shell wall such that a space having a first width is formed between an outer surface of the shell wall and an inner surface of the secondary wall;
- and
- an insulation layer disposed in the space between the secondary wall and the shell wall, the insulation layer having a second width that is smaller than the first width such that the difference between the first width of the space and the second width of the insulation layer forms an air gap within the space,
- wherein the air gap is formed radially adjacent the insulation layer and is configured to resist heat transfer between the shell wall and the secondary wall.
An insulation system for a storage silo having a shell wall and an adjacent insulation layer, the system comprising:
- a secondary wall configured to surround the silo and to be spaced radially outwards from the shell wall such that a space having a first width is formed between an outer surface of the shell wall and an inner surface of the secondary wall;
- and
- a radiation reflective surface provided on the inner surface of the secondary wall that is configured to reflect radiation towards the shell wall.
