| 摘要 |
<p>The present invention is a catalytic gas radiant tube heater, and a method for its use. A radiant tube (10'') encloses a catalyst tube (30) containing a catalyst on a catalyst (60) support (62). Air and a gaseous hydrocarbon fuel diffuse into the catalyst support (62), and react on the catalyst surfaces. The reaction heats the catalyst tube (30), causing the catalyst tube (30) to emit infrared radiation, which heats the radiant tube (10') from within, causing the radiant tube (10') to emit infrared radiation. The infrared radiation emitted by the radiant tube is directed in the desired direction by a reflector (20). The preferred catalyst is cobalt chromium oxide spinel.</p> |
