cm 2 , the pressure of the waste gas 28 from the fuel cell 27 is usually about 3 to 4 kg/cm 2 , which is sufficient. Furthermore, in the embodiment shown in FIG.
It uses a catalytic combustion method as shown in the figure. The combustion catalyst 41 is generally made of platinum (Pt) or palladium (Pd), and is generally heated at 200 to 300°C.
If the temperature is at least 500°C, sufficient ignition and combustion will be possible. However, since the waste gas 7 from the gas turbine 5 satisfies the temperature level for igniting and burning the combustion catalyst, the amount of fuel is reduced by the amount of enthalpy brought in by the waste gas 7. Furthermore, since the catalytic combustion method does not require the use of complicated equipment such as burners, it can have a mechanically simple structure.
