Abstract:
1. A system, comprising: a cylindrical storage tank configured to receive contents under pressure; a catalytic heater element facing the storage tank and spaced therefrom a distance sufficient to permit passage of air between the catalytic heater element and the storage tank, and sufficiently close that substantially any heat radiated outward from a face of the catalytic heater element impinges on a wall of the storage tank; a fuel supply line having a first end coupled to an outlet of a fuel supply, and a second end coupled to a fuel supply inlet of the catalytic heater element; a housing having a face and a back panel, and being defined around a perimeter by sidewalls, the back panel and sidewalls, the face of the housing being substantially open, and the face of the catalytic heater element being substantially coextensive with the face of the housing; an open space between the catalytic heater element and the back panel defining a plenum chamber; a main fuel inlet traversing the back panel and defining the fuel supply inlet, the main fuel inlet configured to deliver fuel to the plenum chamber; a pilot heater positioned entirely within the perimeter of the housing, defined and enclosed by pilot sidewalls extending from the back panel toward the face at least a depth of the plenum chamber, the back panel and the pilot sidewalls being substantially gas-tight, and including a portion of the plenum chamber as a pilot plenum chamber, and configured to deliver fuel to a portion of the catalytic heater element positioned in front of the pilot heater; and a pilot fuel inlet traversing the back panel and configured to deliver fuel to the pilot plenum chamber.
