Abstract
State of coal injection technology. Description of the operating plant for coal injection at blast furnace 1 Schwelgern of the Thyssen Stahl AG. Determination by measuring technique of the energetic processes i nside the tuyeres. Description of the measuring technique: metrologica l investigations of the temperature and analysis distribution within t he tuyere with the aid of a single lance and a coaxial lance. Methods of temperature measurement: thermographic measurements, stationary the rmoelements, temperature measuring lance. Results of the temperature m easurements. Analytical measurements and results. Discussion of the re sults: the temperature and analytical measurements within the tuyere s how that the coaxial lance with additional oxygen injection features a higher combustion efficiency than the single lance.
