PURPOSE: To offer a combustion apparatus for anode waste gas of a fuel cell which is capable of safely and efficiently burning anode waste gas without severe control over anode waste gas feeding to stages and is excellent in durability and maintainability.
CONSTITUTION: A combustion apparatus main body 2 has an oxygen-containing gas inlet 3, two or more anode waste gas inlets 4 and 5, and a combustion gas outlet 5. Pre-combustion chambers 13 and 14 for anode waste gas and oxygen-containing gas, and two or stages of contact beds 9 and 12, consisting of plate-like mixing layers 7 and 10 and honeycomb or plate-shaped catalyst layers 8 and 11, are installed in the combustion apparatus main body 2. The oxygen-containing gas inlet 3 leads to the pre-combustion chamber 13 on time upstream side, and the two or more anode waste gas inlets 4 and 5 respectively communicate with the two or more stages of the pre-combustion chambers 13 and 14. The pre-combustion chambers 13 and 14 are respectively arranged upstream the contact beds 9 and 12, and the mixing layers 7 and 10 upstream the catalyst layers 8 and 11.
