METHOD OF COAL GASIFICATION AND DIRECT IRONMAKING AND SYSTEM THEREFOR |
摘要 |
A system of coal gasification and direct ironmaking which is effective in attaining both heat recovery in a coal-based direct ironmaking process and a reduction in equipment investment in a coal gasification process. The system is characterized by being equipped with: a waste heat boiler (16) for recovering heat of gas exhausted from a coal gasification furnace; a heater (7) provided in exhaust gas lines (la and 1b) of a heat reduction furnace (1) in the coal-based direct ironmaking process and superheating the steam generated by and exhausted from the waste heat boiler (16); and a superheated steam line (23) for supplying the steam superheated by the heater (7) as an oxidant to the coal gasification furnace (10). |
