To provide a combustion device having a simplified structure of low cost and a hydrogen manufacturing device of a fuel cell system, in which both off-gas and fuel gas of high calories are ignited at common flame holes as the combustion device for the hydrogen manufacturing apparatus for a fuel cell attaining hydrogen used in the fuel cell system under a reaction between raw material gas and water vapor.
There are provided a combustion device and a hydrogen manufacturing device having the combustion device in which high calorie gas and off-gas are supplied to flame holes of a combustion device under application of a double-pipe, a fuel gas discharging part is formed at its central part, a slant surface of the flame hole plate expanding in a cone-shape, the flame holes for the high calorie gas are made common to that for off-gas.
