Abstract
A reformer (5) which generates hydrogen-rich reformate gas by causing a catalytic reaction of fuel and air comprises a premixing chamber (12) for premixing the fuel with the air. High temperature air is supplied to the premixing chamber (12) from an air intake tube (13) via an orifice (14). A fuel injector (16) injects the fuel into the flow of the high temperature air in the premixing chamber (12) to generate fuel-air mixture. A homogenizing filter (17) homogenizes the composition of the fuel-air mixture in the premixing chamber (12) and supplies a uniform fuel-air mixture to a reforming catalyst (11).
Claims12
A fuel reformer which generates hydrogen-rich reformate gas by causing a reaction of hydrocarbon fuel in the presence of a catalyst, comprising:
- a premixing chamber for mixing the fuel with high temperature air;
- an air intake tube which supplies the high temperature air to the premixing chamber;
- an orifice disposed between the air intake tube and the premixing chamber, the orifice having a smaller cross-sectional area than a cross-sectional area of the air intake tube;
- a fuel injector which injects the fuel into the high temperature air;
- and
- a homogenizing filter which homogenizes the flow of a fuel-air mixture generated in the premixing chamber and leads the fuel-air mixture to the catalyst.
