Abstract
An energy producing system includes a compressor side for compressing an air/fuel mixture, and a turbine side for producing mechanical, electrical, and/or heat energy, and driving the compressor side. A catalytic combustor is disposed upstream of the turbine side for combusting a steady state air/fuel mixture during a steady state operation of the apparatus. During start-up of the system, the catalytic combustor is preheated by being supplied with a preheat air/fuel mixture capable of lighting-off therein at ambient temperature, whereby oxidization of the preheat air/fuel mixture in the catalytic combustor produces heat. The preheat air/fuel mixture is produced on-site, preferably in a reformer which burns natural gas in the presence of insufficient oxygen for complete combustion, thereby producing hydrogen and carbon monoxide.
