METHOD OF STARTING A PLANT FOR THE PRODUCTION OF PIG IRON OR STEEL PRE-MATERIAL AS WELL AS ARRANGEMENT FOR CARRYING OUT THE METHOD

摘要

A process for starting a plant for producing pig iron, having a direct-reduction shaft furnace and a melt gasifier, is characterised in that, … …  - initially the still empty melt gasifier (6) is heated up by means of a combustible gas and the flue gases (30) formed are introduced into the still empty direct-reduction shaft furnace (1) …  - that coke (31) is charged to the direct-reduction shaft furnace (1) and the flue gases introduced into the direct-reduction shaft furnace (1) are passed through the coke (31) while releasing their sensible heat (Figure 3), …  - that the coke (31) is thereby heated to the ignition temperature and charged in the hot state to the melt gasifier (6) and is ignited by introducing an oxygen-containing gas or oxygen, …  - whereupon a further coal bed or coke bed serving for gasification is charged on top of the ignited bed of coke (31) and the feedstocks are charged to the direct-reduction shaft furnace (1) (Figure 3). …
