Mixed gas distribution system and ammonia synthesis system comprising mixed gas distribution system

A mixed gas distribution system comprising:

• a gas distribution device;
• a mixed gas supply line connected to the gas distribution device;
• a flow induction guide;
• an upper area;
• and
• a plurality of mixed gas flow pipes fixed to a circumference part of a bottom surface of the upper area, and connected to a plurality of openings formed in the circumference part of the bottom surface to enable a movement of mixed gas,
• wherein:
• the gas distribution device is installed horizontally,
• a plurality of mixed gas distribution openings are formed in an outer surface of the gas distribution device for distributing the mixed gas,
• the upper area has the bottom surface and a side surface connecting the bottom surface with an upper wall inside an ammonia synthesis reactor,
• a circular opening is formed in a center of the bottom surface of the upper area,
• the flow induction guide has a side surface connecting an upper circumference of an inner drum included in the reactor with a circumference of the circular opening formed in the center of the bottom surface of the upper area,
• a fixation bracket is disposed on an inner surface of the flow induction guide, and
• the gas distribution device is supported by the fixation bracket.
