(pdf) comparison of different coal based direct reduction

The coal-based processes can be grouped into four categories according to their reduction reactors. The rotary kiln processes include ACCAR/OSIL, DRC, Krupp-CODIR and SL/RN processes. Kinglor Metor

rotary kiln electrotherm engineering & technologies

Coal Based Rotary Kiln for Direct Reduced Iron / Sponge Iron (100 TPD, 350 TPD, 500 TPD) Solid state reduction of Iron Ore using either coal/gas as a medium of reduction to produce a substitute raw material for steel making is termed as Direct Reduced Iron (DRI)

rotary kiln with sl/rn process

Coal Based Rotary Kiln for Direct Reduced Iron / Sponge Iron (100 TPD, 350 TPD, and 500 TPD) Solid-state reduction of Iron Ore using either coal/gas as a medium of reduction to produce a substitute raw material for steel making is termed as Direct Reduced Iron (DRI). Since DRI is produced by removing oxygen from iron ore, its structure is just like a sponge with a network of connecting pores

rotary kilns - feeco international inc

Rotary kilns work by processing material in a rotating drum at high temperatures for a specified retention time to cause a physical change or chemical reaction in the material being processed. The kiln is set at a slight slope to assist in moving material through the drum

thermogravimetric analysis of coal used in rotary kiln of

Abstract. Thermogravimetric analysis (TGA) has been used to research the pyrolysis and combustion processes of coal used in rotary kiln of iron ore oxide pellet. Furthermore, the effects of air flow and oxygen concentration on the combustion behavior of coal were examined with TGA. The results showed that two individual stages can be distinguished for the pyrolysis of coal, the water evaporation stage …

dri production | international iron metallics association

The SLRN coal-based rotary kiln process uses lump ore and, increasingly, pellets as feedstock. There are variants of these processes which are described on the websites of the various technology providers

energy survey of the coal based sponge iron industry

Sep 01, 2015 · In conventional coal based sponge iron plant, Fig. 1, kiln feed (Stream no. 1), which consists of iron ore, feed coal and dolomite, is fed to the rotary kiln (RK). A separate conveyor collects different size fractions of coal (Stream no. 5) for injection into the kiln with the help of pressurized air (Stream no. 4) from discharge end side

how to choose the coal used in cement rotary kiln

Different coal will have different effects,therefore,users must be based on their use of rotary kiln to reasonably choose the coal which meet their requirements,so as to produce better results! So,first of all,we need to understand our needs,then analyze the characteristics of the coal required by the rotary kiln, and then select

coal gasification based production of direct reduced iron

Jan 25, 2020 · The coal-based variant was developed in the 1970s. Coal is pulverized and fed to the gasifier through two sets of horizontally opposed burners using a transport gas (either syngas or nitrogen). Preheated O2 and steam (as a moderator) are mixed and fed to the injector, where they react with the coal to produce syngas consisting mainly of H2 and CO with only small amount of CO2 and no …

rotary kiln to making sponge iron

Iron and Steel Making Machines - Coal Based DRI Plant , Quality of sponge iron made by the Tunnel Kiln technology is superior as compared to that made from the rotary kilns because, while the input raw material gets just about 24hours for the reaction, the figures almost reverse in case of the Tunnel Kiln
