In order to solve the problem of energy consumption, improve efficiency utilization and develop new energy, total consumption fluctuation thermal integrated were analyzed. Four suggestions are put forward for power system flexible plant, namely, electric heat storage system, pump g, heating high pressure via steam turbine, which can air capacity reduce coal system. Among them, in case small con...

A dynamic, first-principles process model for a steelmaking electric arc furnace has been developed. The is an integrated part of application designed optimization during operation the furnace. Special care taken to ensure that non-linear robust and accurate enough real-time optimization. formulated in terms state variables ordinary differential equations adapted data using recursive parameter ...

Steelmaking based on direct reduced iron (DRI, and its compacted derivative hot briquetted iron, HBI) is an anticipated important global alternative to current steel production FeOx reduction in blast furnaces due lower specific CO2 emission. The majority of DRI melted refined the electric arc furnace with different process conditions compared melting scrap raw material composition being rather...

Since its invention until the 1950s, the iron blast furnace was viewed as a strange ‘black box’. Its operation was largely empirical and much of the information needed for monitoring and control of the process was yet to be known. More complete information was needed concerning the process such as the reduction of iron-bearing raw materials, the distribution of materials throughout the stack, t...

Silicon is produced in submerged arc furnaces which are heated by electric currents passing through the furnace. It important to understand distribution of heating within furnace order accurately model silicon production process, yet many existing studies neglect aspects this current flow. In present paper, we formulate a that couples electrical thermal, material flow and chemical processes We ...
