The basic energy indices of steelmaking processes, namely, the consumption of energy carriers, the total energy intensity, the full energy efficiency of a process, and the amount carbon dioxide released in atmosphere, are considered. The energy, ecology, and economic efficiencies of the processes are quantitatively analyzed for various alternative energy carriers during steelmaking in an ASF. The problem of sustainable development of an object in the environment is analyzed in relation to its main three parameters, namely, economics, energetics, and ecology. [ABSTRACT FROM AUTHOR] |
