To provide a combustion device allowing complete combustion of combustion gas, improving heat efficiency of a reformer, and having excellent durability.
The combustion device includes a flame plate provided with a second combustion gas ejection part to surround a first combustion gas ejection part provided at the center part, a second combustion gas chamber communicated with the second combustion gas ejection part at the upstream of the flame plate, and a second combustion gas ejection means for ejecting second combustion gas to a direction nearly orthogonal to an ejection direction of first combustion gas and to the ejection direction of the first combustion gas at the downstream of the flame plate. Accordingly, the second combustion gas is completely burned by primary air and secondary air according to an ejection amount of the second combustion gas ejected by the second combustion gas ejection means.
