Blast Furnace Operation with Oxygen-Enriched Unheated Blast Air

摘要

Three trials with oxygen-enriched unheated blast air are described. The trials were conducted in the Bureau of Mines experimental blast furnace located in Bruceton, PA. For the first trial, moisture was added to the oxygenated blast. The second and third trials were conducted with natural gas injection. The test was basically a feasibility study; the practice was demonstrated to be feasible and also have possible advantages over hot blast operation. The testwork was conducted in 1964 and 1965 as part of a continuing study of ironmaking technology in cooperation with several North American steel companies.
