Embodiment

The present invention is described in detail below in conjunction with drawings and Examples:

Consult Fig. 2, Fig. 3, a preferred embodiment of fuel gas generation device of the present invention comprises control unit 6 among a generator unit 4, heat energy feeding unit 5 and.

This generator unit 4 has the hot gas engine 41 that conversion thermal energy is a kinetic energy, and conversion kinetic energy is a generator 42 of electric energy.

This heat energy feeding unit 5 has one first cavity 51 defining a firing chamber 501, defines one second cavity 52 of a vacuum chamber 502 around this first cavity 51 and with this first cavity 51, is communicated with and imports respectively a Flow valve 53 of combustion gas with this firing chamber 501, and passes this first, second cavity 51,52 and be communicated with a discharge passage 54 extraneous and this firing chamber 501.This firing chamber 501 contacts with this hot gas engine 41.This Flow valve 53 is used to carry air and hydrocarbon to this firing chamber 501.This discharge passage 54 is used to discharge the product after the burning.What deserves to be mentioned is that aforementioned hydrocarbon can be that hydrogen, rock gas, refining hydrogen, electrolysis by-product hydrogen are wherein a kind of, this preferred embodiment is to form combustion gas behind the hydrogen mixing air.

Should in control unit 6 have and be arranged in this firing chamber 501 and a temperature detector 61 that contact with this hot gas engine 41, be used to light an ignition 62 of combustion gas in this firing chamber 501, reach a central controller 63 that is electrically connected and is used for program setting one value range T with this temperature detector 61, this ignition 62, this Flow valve 53.This value range T has a upper change point T1, and a lower-limit point T2.

Consult Fig. 2, Fig. 3, and Fig. 4, below promptly at the present invention and in conjunction with previous embodiment explanation as back:

Step 71: see through upper change point T1 and lower-limit point T2 that this central controller 63 is set this value range T.

Step 72: see through these gas mixer 531 input combustion gas of these central controller 63 controls to this firing chamber 501, and drive the combustion gas of igniting of this ignition 62, temperature in this firing chamber 501 is sharply risen, and conduction heat energy is to this hot gas engine 41, make this hot gas engine 41 produce kinetic energy, see through again and export after this generator 42 is converted to electric energy with kinetic energy.

Step 73: with the temperature in this this firing chamber 501 of temperature detector 61 detectings.
