Photothermal power generation device and method

A photothermal power generation device comprising:

• a combustor for receiving a supply of fuel and air, burning the fuel, and producing a combustion gas;
• an emitter heated by allowing the combustion gas produced in the combustor to flow through a combustion gas flow passage;
• a photoelectric conversion element for receiving light emitted from the emitter and converting the light into electric power;
• and
• a combustor fire vent adjusting unit for adjusting at least one of shapes and a number of, fire vents formed in the combustor, in accordance with a required output of power generation.

A photothermal power generation device comprising:

• an emitter heated by allowing the combustion gas produced in the combustor to flow through a combustion gas flow passage;
• a photoelectric conversion element for receiving light emitted from the emitter and converting the light into electric power;
• and
• a discharge state adjusting unit for adjusting a discharge state of exhaust gas on the basis of a state of the combustion gas;
• wherein the discharge state adjusting unit comprises an exhaust fan.

A method of generating photothermal power, comprising the steps of:

• receiving fuel and air in a combustor;
• burning the fuel and producing a combustion gas;
• heating an emitter by flowing the combustion gas through the emitter;
• emitting light from the heated emitter;
• receiving the emitted light in a photoelectric conversion element and converting the light into electric power;
• and
• adjusting a resistance to flow of the combustion gas in the emitter with a flow resistance adjusting unit.
