This study focuses on sponge iron kiln based process. The chemical process involved in making sponge iron removes oxygen from iron ore by using a reducing agent in the form of non-coking coal [Patra et al, (2005)]. The reduction process is carried out in an inclined horizontal rotary kiln, which rotates at a programmed speed. A temperature.

Sponge Iron Production In Rotary Kiln

Non-coking coal is required in sponge iron production, since the coking reaction leads to formation of rings inside the kiln. Practically permissible caking index is 3 maximum for rotary kiln operations. 2) Low ash contents - High ash leads to under utilization of the kiln volume available for reduction.

Sponge iron making is a process in which iron ore lumps typically 5mm18mm size are tumbled with a select grade of ironcoking coal little dolomite inside an inclined rotary kiln and control combusted in the presence of air for about 12 hours before the products are air cooled magnetically separated screened and size wise in finished.

DRI, also known as sponge iron, is the product of reducing iron oxide in the form of iron ore and steel plant wastes into metallic iron, below the melting point of iron and typically in the range of 800–1200 C. Iron oxide is charged into shaft furnace, rotary kiln, or fluidized beds in the form of pellet, iron ore lumps, or fines. The reduction takes place using gaseous reductants (CO + H.

Direct Reduction Process In A Rotary Kiln

Direct Reduction Process In A Rotary Kiln

Raw material mix-iron ore, dolomite and coal are fed to one end of rotary Kiln and product sponge iron along with char is taken out from the other end. Apart from this, primary and secondary airs are supplied to the Kiln to initiate the combustion and reaction processes. The reaction takes place at.

Abstract. In this chapter, the rotary kiln freeboard aerodynamic phenomenon is described drawing parallels with fluid flow in conduits. The goal is to describe the characteristics of confined jets that determine burner aerodynamic mixing and, in turn, combustion.

Rotary kiln is cylindrical in shape and is 80m long having 4.2m internal diameter. This is the reactor of the process where reduction as well as combustion reactions are carried out. The role of kiln is to convert the raw material (iron ore, coal and dolomite) into the sponge iron [8]. Detail reaction mechanism of the process is discussed below.

BACKGROUND OF THE INVENTION. 1. Field of the Invention . This invention relates to a process of directly reducing iron oxide-containing material to produce sponge iron in a rotary kiln by a treatment with solid carbonaceous reducing agents having a high content of volatile combustible constituents, e.g., 25 to 50 weight percent in which the charge is moved through the rotary kiln opposite to.
