Thermodynamic Analysis Method for Iron and Steel Manufacturing System Based on Enthalpy Balance

Abstract

Thermodynamic analysis method for iron and steel manufacturing system is developed to describe the energy flow. The theoretical energy consumption for the manufacturing process is proposed to analyze the energy-saving potential. Energy balance based on enthalpy with a uniform reference state is established to analyze the amounts and forms of energy flow in the manufacturing system. The energy-saving potential of blast furnace system is discussed to choose the appropriate energy-saving methods and technologies.

Interaction mechanism among material flows, energy flows and environment and generalized thermodynamic optimizations for iron and steel production processes
