    Abstract:

    A multiphase mathematical model based on the transport equations of momentum energy and chemical species is improved to take into account the inject of rich hydrogen gas into the mini blast furnace based on biomass technology. A base case of charcoal mini blast furnace operation is simulated and compared with industrial operations parameters. Thus, newly operation techniques are proposed to investigate new technologies of low carbon intensity. In this study, a parameter of carbon intensity is proposed to compare the new technologies based on the gas injection into multilevel tuyeres. The simulations results indicated that carbon intensity parameter can be reduced lower than 40%, which represents clearly new possibilities for the reduction step using mini blast furnace technologies and could open new possibilities for the reduction technology.
