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.
Claims21
1-22. (canceled)
A gas fired catalytic heater comprising:
- a hydrocarbon catalyst pad for igniting a hydrocarbon fuel;
- an alcohol injection device;
- and
- 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
- 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.
An alcohol self-igniting catalyst pad for insertion in an explosion proof gas fired catalytic heater behind a hydrocarbon catalyst pad, 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, the alcohol self-igniting catalyst pad comprising:
- a flexible wash coat;
- and
- a noble metal catalyst highly dispersed on the wash coat.
A method of igniting a gas fired catalytic heater, the method comprising:
- i) initiating an exothermic reaction between an alcohol self-igniting catalyst pad and alcohol for providing activation energy to a hydrocarbon catalyst pad,
- ii) contacting the hydrocarbon catalyst pad with a hydrocarbon fuel once the necessary activation energy has been imparted to the hydrocarbon catalyst pad from the exothermic reaction to initiate combustion of the hydrocarbon fuel across the hydrocarbon catalyst pad.
