<P>PROBLEM TO BE SOLVED: To provide a vaporizer capable of stably producing a vaporized gas and performing stable ignition by significantly increasing a heat transfer area of a former stage-vaporization chamber of a vaporizing section with a simple constitution, and efficiently and uniformly transferring heat even in a latter stage-vaporization chamber. <P>SOLUTION: In the vaporizer composed of the vaporizing section 1 for heating and vaporizing liquid fuel, and a nozzle section 2 for jetting the vaporized gas from the vaporizing section 1, a cylindrical sintered metal mesh 13 is disposed on an inner face of an inner pipe 5 defining the former stage-vaporization chamber 6, a heat transfer pipe 16 as a passage of the vaporized gas, in which projecting sections 14 and recessed sections 15 are alternately arranged in the circumferential direction, is disposed between an outer pipe 7 defining the latter stage-vaporization chamber 8 communicated with the former stage-vaporization chamber at its tip section, and a storage pipe 17, and the latter stage-vaporization chamber 8 is divided into a number of passages. <P>COPYRIGHT: (C)2012,JPO&INPIT |
