The hot gases may be generated in an external furnace or by a flame inside the kiln. Our cement rotary kiln and sponge iron rotary kiln has been developed for performing drying, calcination and sintering work in a continuous process. Widely used for cement, pet coke calcination, sponge iron and other materials, it uses hot gases for the operation.
Sponge Iron Production in Rotary Kiln Bidyapati
This book comprehensively deals with the production of sponge iron in the rotary kiln. The book is divided into 17 chapters. The initial chapters give a brief on the fundamental theories and basic principles of sponge iron production, commercially used DR (direct reduction) processes and physico-chemical principles of sponge iron production.
Prakash Industries commissions sixth sponge iron
2019-10-18 · Prakash Industries has commissioned its sixth sponge iron rotary kiln and has started commercial production. The kiln has a capacity of two lakh tonnes per annum of sponge iron
SPONGE IRON PRODUCTION IN ROTARY KILN PDF
Sponge iron production in rotary kiln. The cooler is also inclined at 2. The largest improvements would be made by design modifications adopting a novel energy conservation scenario by process integration and thereby decreasing the coal and water consumption and by decreasing the cold fresh air.

Sponge Iron Plant Suppliers & Exporters in
In the DRI plant, production of sponge iron using a solid reductant involves reducing iron ore (lumps/pellets) with a carbonaceous material like coal or lignite. The reduction is carried out in a rotary Kiln (which is inclined and rotates at a pre-determined range of speed) at
Accretion Control in Sponge Iron Production Kiln using
processing plant determines the type of control strategy to be implemented. Sponge iron production process requires accurate monitoring and control of the process parameters. The performance of rotary kiln sponge iron based processes is normally affected by accretion build up along the kiln linings. Accretion build up is the
Flow of materials in rotary kilns used for sponge iron
Abstract. Looking forward to the need of developing coal-based sponge iron technology in India, a country having no significant resources of either coking coal or natural gas, the Research and Development Division of the Tata Iron and Steel Company Limited (TISCO) set up a rotary kiln based direct reduction pilot plant in 1975.
sponge iron tunnel kiln mvdeburcht.nl

Modelling and optimization of a rotary kiln direct
2015-7-3 · Rotary kilns are used for a range of mineral processing operations. Kilns range in size from 2–6 m in diameter and can be 50–225 m long with an operating mass of up to 3000 t. Two of the most common applications are cement production and sponge iron production. Hatch uses a proprietary one-dimensional kiln model
ENERGY INTEGRATION IN SPONGE IRON PLANT USING
2012-5-12 · In the present work a system is designed to integrate the heat of waste gas in the sponge iron process. For this purpose a case study of typical sponge iron production process is considered. Waste gas from the rotary kiln of the sponge iron plant exits at a temperature around 900 C.
