  • How does coke and coal play into steel making

    Jun 22 2016  It is produced by baking coal until it becomes carbon by burning off impurities without burning up the coal itself. When coke is consumed it generates intense heat but little smoke making it ideal for smelting iron and steel. Prior to the 1880’s steel was produced using charcoal. By 1920 nearly 90 of US steel was produced using coke.

    Coal Cargo

    The main consideration to keep in mind with coal is that it emits methane an odourless flammable gas which is less dense than air. This gas is emitted particularly if the coal has been freshly mined or if it is dropped into the hold when loading causing it to break up. Thus a risk of fire and explosion is always present on a ship carrying coal.
