<P>PROBLEM TO BE SOLVED: To enable separately supplied steam and raw material to be distributed to a plurality of reformers after they have been homogeneously mixed. <P>SOLUTION: In the annular mixing and distributing header, an annular mixing chamber 35 and an annular distributing chamber 36 are arranged in a stacked relationship via a partition plate 37. In the mixing chamber 35 a block plate 38 is provided, in the partition plate 37 of the one side position of the block plate 38 an orifice 39 for communicating to the distributing chamber 36 is provided, and in the mixing chamber 35 a circulated flow path 40 in one direction that is led to the orifice 39 via a fluid-agitating area 41 from the other side position of the block plate 38 is formed. The steam 13 and the raw material 9 which are supplied from supplying tubes 43 and 44, respectively, to the mixing chamber 35 are agitated when they pass through the fluid-agitating area 41 of the circulated flow path 40 so that they become a homogeneously mixed gas 46, and the homogeneously mixed gas 46 that is led to the distributing chamber 36 through the orifice 39 is dispersed in the peripheral direction and then distributed and supplied to each reformers 5. <P>COPYRIGHT: (C)2008,JPO&INPIT |
