Abstract

1439717 Oil injection in blast furnaces NIHON SEKIYU HANBAI KK 16 May 1974 21908/74 Heading C7D Coke consumption in the blast furnace production of pig iron is reduced by injecting an atomized fluid fuel composed of a 'light' fraction having a B.P.<250‹C, and a 'heavy' fraction having a B.P.>250‹C. The 'light' fuel is present in the range of 3-50 wt per cent of the total, and may be petroleum naphtha, methanol, light fraction from coal tar, hydrocarbons containing 1-9 C atoms or alcohols containing 1-8 C atoms. Examples of the 'heavy' fuel are petroleum heavy oil, heavy coal tar, and heavy oil. A fuel containing the two fractions may be used, e.g. crude oil, crude coal-tar oil.
