Abstract
A catalytic heating system for heating a beverage or food that comprises: a container for containing the beverage or food and a catalytic combustion assembly for heating the container, with the catalytic combustion assembly comprising a fuel supply assembly having a fuel canister for supplying a fuel gas having a stoichiometric ratio of about 15 to an air mixing injector for injecting the fuel gas into an elongate sidewall enclosure having curved shape and defining an enclosed catalytic combustion chamber where a catalytic combustion process is generated, causing the complete combustion of all of the fuel gas and heating the container containing the beverage or food.
Claims24
A catalytic heating system for heating a beverage or food, comprising:
- a container for containing the beverage or food;
- a catalytic combustion assembly for heating the container, comprising:
- a chamber plate having a top side and a bottom side, with the top side of the chamber plate integral with the bottom of the container;
- an elongate sidewall enclosure integral with and contained within the chamber plate, with the elongate sidewall enclosure forming an enclosed catalytic combustion chamber;
- with the elongate sidewall enclosure having a fuel gas inlet and an exhaust outlet within corresponding ends of the elongate sidewall enclosure;
- with the fuel gas inlet and exhaust outlet extending through the bottom side of the chamber plate;
- and with the elongate sidewall enclosure thereby providing flow-through paths for a fuel gas to enter the enclosed catalytic combustion chamber through the fuel gas inlet and for an exhaust to exit the enclosed catalytic combustion chamber through the exhaust outlet;
- a catalytic reaction media disposed within the enclosed catalytic combustion chamber;
- a combustion starting element disposed within the enclosed catalytic combustion chamber;
- a fuel supply assembly mounted on a fuel supply platform, with the fuel supply assembly having a fuel and air mixing injector fluidly connected to the fuel gas inlet;
- a fuel canister sealably connected to the fuel supply platform and fluidly connected to the fuel supply assembly, with the fuel canister for containing the fuel gas;
- and
- a shell containing the container and catalytic combustion assembly, thereby forming the catalytic heating system for heating the beverage or food;
- whereby the fuel and air mixing injector within the catalytic combustion assembly can entrain the fuel gas with air and inject a fuel gas and entrained air mixture into the enclosed catalytic combustion chamber where the combustion starting element can ignite the fuel gas and entrained air mixture, and the catalytic reaction media can maintain a catalytic combustion process within the enclosed catalytic combustion chamber, and with the heat energy generated within the catalytic reaction media transferred by thermal conduction to the chamber plate integral with the bottom of the container for containing the beverage or food.

A catalytic heating system for heating a beverage or food, comprising:
- an upper shell;
- a container disposed within the upper shell, with the container for containing the beverage or food;
- a catalytic combustion assembly for heating the container, comprising:
- a chamber plate having a top side and a bottom side, with the top side of the chamber plate for contacting the bottom of the container;
- an elongate sidewall enclosure integral with and contained within the chamber plate, with the elongate sidewall enclosure forming an enclosed catalytic combustion chamber;
- with the elongate sidewall enclosure having a fuel gas inlet and an exhaust outlet within corresponding ends of the elongate sidewall enclosure;
- with the fuel gas inlet and exhaust outlet extending through the bottom side of the chamber plate;
- and with the elongate sidewall enclosure thereby providing flow-through paths for a fuel gas to enter the enclosed catalytic combustion chamber through the fuel gas inlet and for an exhaust to exit the enclosed catalytic combustion chamber through the exhaust outlet;
- a catalytic reaction media disposed within the enclosed catalytic combustion chamber;
- a combustion starting element disposed within the enclosed catalytic combustion chamber;
- a fuel supply assembly mounted on a fuel supply platform, with the fuel supply assembly having a fuel and air mixing injector fluidly connected to the fuel gas inlet;
- a fuel canister sealably connected to the fuel supply platform and fluidly connected to the fuel supply assembly, with the fuel canister for containing a fuel gas;
- and
- a lower shell containing the catalytic combustion assembly, with the lower shell releasably attached to the upper shell, thereby contacting the top side of the chamber plate with the bottom of the container and forming the catalytic heating assembly for heating a beverage or food and contacting the chamber plate with the bottom of the container;
- whereby the fuel and air mixing injector within the catalytic combustion assembly can entrain the fuel gas with air and inject a fuel gas and entrained air mixture into the enclosed catalytic combustion chamber where the combustion starting element can ignite the fuel gas and entrained air mixture, and the catalytic reaction media can maintain a catalytic combustion process within the enclosed catalytic combustion chamber, and with the heat energy generated within the catalytic reaction media transferred by thermal conduction to the chamber plate in contact with the bottom of the container for containing the beverage or food.
