PURPOSE:To improve the heating efficiency by covering the upper area of an expansion cylinder with the heat insulative radiation plate having a high radiation rate and introducing a heater tube into the back of the radiation plate, in the combustor for heating a heater by combusting the fuel for a thermal gas engine. CONSTITUTION:In the combustor for a thermal gas engine, the combustion air introduced from an air stream inlet 1 performs heat exchange with exhaust gas and temperature rises in a heat exchanger 2, and the air is provided with swirling by a swirler 4 and flows into a combustor 5. Fuel is jetted from a fuel nozzle 6, and mixed with the combustion air described the above, and ignited by a spark plug 7 and combusted, then discharged through a heater tube 8, heat exchanger 2, and an exhaust outlet 9. In this case, the upper area of the expansion cylinder 10 onto which combustion gas collides is covered with the heat insulating radiation plate 13 having a high radiation rate, and the heater tube 8 brached from the concentrated pipe 14 of the expansion cylinder 10 are arranged radially on the back side of the radiation plate 13, ad allowed to communicate to a regenerator 11. |
