METHOD OF SUPPLY ON NATURAL GAS INTO TUYERES OF BLAST FURNACE Russian patent published in 1996 - IPC

Abstract RU 2061053 C1

FIELD: ferrous metallurgy. SUBSTANCE: method can be used for injection of natural gas into air tuyeres of blast furnaces. Natural gas is mixed in advance with oxygen- carrying containing oxygen 0.5-25.0 per cent by mass. Reduction of cost of method is achieved since compressed air is used as oxygen-carrying gas. With same purpose in view compressed agglomeration gases can be used. EFFECT: increased efficiency of use of natural gas with simultaneous decrease of cost for its preliminary preparation before use. 3 cl
