Abstract
A gas fired catalytic heater is provided that foregoes the need for an electrical heating element to provide the activation energy for the hydrocarbon catalyst pad. An alcohol self-igniting catalyst pad is used to provide the activation energy to the hydrocarbon catalyst pad thereby removing dependence of the heater on an outside electrical energy source to initiate start-up of the heater. The catalyst pad includes a flexible wash coat; a noble metal dispersed on the wash coat; an anti-sintering element saturating the wash coat; and a catalyst promoter saturating the wash coat.
Claims13
A gas fired catalytic heater comprising:
- a hydrocarbon catalyst pad for igniting a hydrocarbon fuel;
- an alcohol injection device;
- an alcohol self-igniting catalyst pad in communication with the alcohol injection device, the alcohol self-igniting catalyst pad adapted for exothermic reaction with alcohol to provide activation energy to activate the hydrocarbon catalyst pad and initiate catalytic combustion of the hydrocarbon fuel when injected thereacross;
- and
- a regenerating moisture trap in proximity to the alcohol self-igniting catalyst pad for adsorbing moisture thereby reducing moisture adsorbed by the alcohol self-igniting catalyst pad;
- wherein the alcohol injection device comprises holes situated adjacent the alcohol self-igniting catalyst pad for spraying alcohol onto the surface of the alcohol self-igniting catalyst pad when alcohol is injected into the alcohol injection device.
