Abstract
An apparatus and process for rapidly injecting or blowing solid combustible material into a metal pool is presented. In a preferred embodiment, the apparatus essentially comprises at least one nonoxidizing compressed gas source, a circuit which supplies granulated carbonaceous material suspended in a carrier gas, at least one circuit which supplies flushing gas, various means for metering different flow rates of the gas and solid particulate streams and means for separately or jointly connecting the above described circuits to appropriate conduits which terminate in a blowing lance.
