Method of coal gasification and direct ironmaking and system therefor |
摘要 |
A system of coal gasification and direct ironmaking attains both heat recovery in a coal-based direct ironmaking process and a reduction in equipment investment in a coal gasification process. A waste heat boiler in the system recovers heat of gas exhausted from a coal gasification furnace. A heater in exhaust gas lines of a heat reduction furnace in the coal-based direct ironmaking process superheats the steam generated by and exhausted from the waste heat boiler. A superheated steam line supplies the steam superheated by the heater as an oxidant to the coal gasification furnace. |
