Abstract: A system for shielding an interior metal surface of a metal container from a hot fluid within the metal container wherein the hot fluid is at a temperature greater than a temperature limit of the metal, including a first insulating layer including metal clad insulation proximate the interior metal surface, a second insulating layer spaced from the first insulating layer including a perforated reflective metal shield and a third insulating layer spaced from the second insulating layer which is structurally stable and substantially inert to the hot fluid.
