Physico-chemistry of coal combustion under blast furnace tuyere conditions*
Physico-chimie de la combustion du charbon dans les conditions des tuyères de haut-fourneau
Replacement of metallurgical coke by pulverized coal injected in blast furnace tuyere is a major economical challenge, due to the high price of coke.
Combustion conditions of the coal in this system are quite different compared to usual combustors : high temperature (1 200 °C-2 000 °C), short residence time in presence of oxygen (less than 30 ms), followed by gasification in the presence of C02.
Within the frame of a collaboration IRSID-CNRS, a series of experiments has been conducted to reproduce at the laboratory scale the industrial conditions.
