Claim 19:
20. The method of claim 19, wherein the heating and igniting of the fuel carried through the ignition tube in a multiple of stages comprises:
receiving the fuel particles after recirculating in a first stage of the ignition tube;
further irradiating the fuel particles by the beam of laser light in the first stage of the ignition tube, the further irradiation leading to combustion and flame generation;
receiving the fuel particles undergoing combustion and flame generation in a second stage of the ignition tube; and
additional irradiating of the fuel particles undergoing combustion and flame generation in the second stage of the ignition tube by the beam of laser light, the additional irradiation leading to further flame growth and propagation.
