Model Study of Blast Furnace Operation with Central

2/8/2019· Blast furnace (BF) remains the dominant ironmaking process worldwide. Central coke charging (CCC) operation is a promising technology for stabilizing BF operations, but it needs reliable and quantified process design and control. In this work, a multi-fluid BF model is further developed for quantitatively investigating flow-thermal-chemical phenomena of a BF under CCC operation. This

How Does a Blast Furnace Work? – Hani Tech

In the blast furnace production, iron ore, coke, and slag-forming flux (limestone) are charged from the top of the furnace, and preheated air is blown from the tuyere loed at the lower portion of the furnace along the circumference of the furnace.

A GUIDE TO THE OLD STONE BLAST FURNACES PENNSYLVANIA

blast furnace evolved. Itwas all a matter of economics, supply and demand, technology, etc. This furnace was charged from ground level. Inthe early years, the blast was powered by water turning a wheel which in turn either worked a bellows (early furnaces) or

Blast furnace - Wikipedia

Blast furnaces operate on the principle of chemical reduction whereby carbon monoxide, having a stronger affinity for the oxygen in iron ore than iron does, reduces the iron to its elemental form. Blast furnaces differ from bloomeries and reverberatory furnaces in that in a blast furnace, flue gas is in direct contact with the ore and iron, allowing carbon monoxide to diffuse into the ore and

Simulation of Burden Distribution and Charging in an

1/1/2015· I T TI The burden distribution in the blast furnace is controlled by selecting a burden charging progra , i.e., the aterials, their a ounts and positions here they are charged into the blast furnace. It is the pri ary eans of controlling the conditions in the lu py zone, including the aterial flo s, heat and ass transfer and che ical reactions.
