An object of the present invention is that it is small reformer but to provide a reformer and reforming method shows the advantage for large-scale reformer in terms of investment costs and operating costs .
The present invention is, gaseous hydrocarbons - steam reforming method and reformer relates to (100), the first fuel / air mixture logistics (102) by partial combustion, gaseous hydrocarbons - of water vapor flow heating the fuel / air mixture flow used during the reforming, the second fuel / air mixture flow is burned, gaseous hydrocarbons - heating the air stream used during the reforming of the steam flow , gaseous hydrocarbons - water vapor stream is reformed, thereby forming synthesis gas stream (110) and the fuel gas stream (112).
