<p>PURPOSE:To improve thermal efficiency by preventing pressure loss by a preheating means heating compressed air. CONSTITUTION:A fuel mixing section 42, in which compressed air from a compressor 3 and fuel are mixed, a catalytic combustion section 43, in which the mixture is burnt by a catalytic reaction, and a preheating heater 45, in which compressed air is heated, are provided. A bypass hole 41b introducing compressed air from the upstream side of the preheating heater into the fuel mixing section, a slide ring 46 opening and closing the bypass hole, an ECU 50 driving the slide ring and opening the bypass hole when the disuse of heating by the preheating heater is decided and a driving means 51 are furnished. When the bypass hole 41b is opened, compressed air is not passed through the preheating heater 45, passed through the bypass hole and introduced into the fuel mixing section 42, thus obviating pressure loss.</p> |
