Flash ironmaking system and method

A flash ironmaking system, comprising:

• a pulverized coal gasifier defining a material inlet and a coal gas outlet, and configured to mix pulverized coal, pure oxygen and steam to obtain a crude coal gas containing carbon monoxide and hydrogen;
• a drying pre-reduction kiln defining a wet iron ore inlet, a block coal inlet and a charging material outlet, and configured to dry and pre-reduce wet iron ore and block coal to obtain pre-reduced iron ore;
• and
• a flash furnace comprising:
• a horizontal bottom defining a hearth in which a molten iron layer region, a slag layer region and a carburizing bed layer region are sequentially formed from bottom to top,
• a reduction tower defining a reduction tower chamber therein, and a lower end connected to an upper end of the carburizing bed layer region,
• a concentrate nozzle provided at a top of the reduction tower, connected to the charging material outlet and the coal gas outlet respectively, and configured to only feed the pre-reduced iron ore, the crude coal gas and a fuel containing pure oxygen and pea coal to the reduction tower chamber to obtain metal iron and a flue gas,
• a flue defining a lower end connected to the upper end of the carbonizing bed layer region, wherein a flue gas vent is formed in a side wall of the flue and communicated with the drying pre-reduction kiln.
