sponge iron process

Based on our experience an ideal coal based sponge iron plant shall have the following facilities. As the manufacture of sponge iron is very sensitive to the physical and chemical characteristics of raw materials, a well designed raw material preparation plant with crushing/screening facility for iron ore and coal to control the size of input materials to the kiln is a prime requiste.

Energy survey of the coal based sponge iron industry ...

01-09-2015  The efficiency of the coal based sponge iron process is defined as the energy needed for the reduction reactions compared to the energy added to the system. Due to chemical reactions and combustion the heat generated inside the kiln is 64.98 Gcal/h and the heat value of coal input is 118.6 Gcal/h resulting in a thermal efficiency of the process to be 51.31%.

It has been found out that around 1.6-1.75 tonne of Fe, 1.2- 1.5 tonne of coal 0.035 tonne of dolomite are required for production of one tonne of sponge iron. This results in production of 0.54 tonne of solid waste which includes 0.25 tonne of dust and 0.29 tonne of coal char. Due to non- availability of good grade of coal, the amount of char fines increases.

Sponge Iron - an overview ScienceDirect Topics

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

DESIGN OF WASTE HEAT RECOVERY SYSTEM IN A SPONGE IRON

(DRI). Sponge iron is produced primarily both by using non-coking coal and natural gas as reductant and therefore classified as coal based and gas based process respectively. Due to a promising availability of coal, the coal based sponge iron plants share the major amount of its production.

Summary of findings from HYBRIT Pre-Feasibility Study 2016 ...

volatile matter in coal are used as energy for the high temperature baking process in coke production. Even though the existing LKAB-SSAB production system is one of the most efficient of its kind worldwide, it emits around 6 million tonnes of carbon dioxide per year in Sweden. BLAST FURNACE 3 The iron ore and coke is added to a process designed

Profitability analysis of power generation using waste ...

15-12-2017  In the sponge iron process coal is the only source of energy, which produces through its combustion. The coal consumption is determined by energy demand of the process, which depends on preheating of feed materials and air, heat involved in reduction reactions, heat lost through the kiln wall, preheating required by coal itself and latent heat required for evaporation of moisture of feed material.
