The high-temperature steam is used in the fields of industrial, residential, and commercial. Especially, in case of high-temperature steam, it can be used to produce hydrogen and likewise it can be used to generate electricity in the field of power generation. However, the steam condition for producing hydrogen and the steam condition for producing electricity are different, it is considerably important to distribute the high-temperature steam in condition satisfying each demand. Moreover, the required pressure and the pressure loss of a steam distributor at the load side should be considered. Therefore, In this study, the numerical simulation using ANSYS fluent was performed by dividing into pipe A(4,000kPa at use of power generation system) and pipe B(300kPa at use of hydrogen production). In addition, it was simulated according to the variation of diameter of pipe B(20mm - 30mm) for analysis of a steam distribution techology. The pressure outlet that can be used in hydrogen production was about 300kPa approximately when the diameter of pipe B was 20mm. As a result, the distribution technology that is used hydrogen production and in the power generation system was obtained through numerical simulation in proposed condition.
