FUEL REFORMING APPARATUS

摘要

A mixer to mix a fuel with air includes plural fluid inlets, at least one fluid outlet, a casing, a plurality of stirring blades, and a particle material or a porous material. The casing has a substantially tubular shape extending in an axial direction of the casing between the plural fluid inlets and the at least one fluid outlet. The plurality of stirring blades are provided in the casing to align in the axial direction so that a torsional turning direction of the plurality of stirring blades is sequentially reversed in an order of alignment. The particle material or a porous material is disposed in the casing to fill an entire space containing the plurality of stirring blades from the plural fluid inlets to the at least one fluid outlet. Sizes of gaps existing in the entire space are less than a quenching distance of the fuel.

主权项

1. A fuel reforming apparatus comprising:
a reformer containing a reforming catalyst that reforms a fuel mainly composed of a hydrocarbon by using air and produces an alcohol; a mixer that is provided on the upstream side of the reformer, mixes the fuel with air, and supplies the mixture to the reformer; and a condenser that is provided on the downstream side of the reformer and separates the gas produced from the reformer into a condensed phase mainly composed of the reformed fuel and a gas phase, wherein the mixer includes two or more fluid inlets and one or more fluid outlets; a casing with a substantially tubular shape as a whole extending in the axial direction between the fluid inlets and the fluid outlets; a plurality of fixed stirring blades provided to align in the axial direction in the casing so that the torsional turning direction is sequentially reversed in the order of alignment; and a particle material or a porous material disposed to fill the entire remaining space of a housing part that is set to house at least the plurality of fixed stirring blades in a space including the inside of the casing and that extends from the fluid inlets to the fluid outlets; and the size of a gap produced in the entire remaining space in which the particle material or porous material is disposed is less than the quenching distance of the fuel supplied from the fluid inlets.
