the coal based direct reduction rotary kiln process was developed for converting iron ore directly into metallic iron without the melting of the materials. the process has the advantage of low capital expenditure and no requirement of coking coal. the metallic iron in this process is produced by the reduction of iron oxide below the fusion temperature of iron ore (1535 deg c) by utilizing

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). since dri is produced by removing oxygen from iron ore, its structure is just like sponge with a network of connecting pores. these
waste gas from the rotary kiln of the sponge iron plant exits at a temperature around 900 c. this gas has a lot of sensible heat and can be used for energy integration. this heat is used for heating water in a boiler. superheated steam which is produced in the boiler is used to rotate a prime mover like a steam turbine. the objective in the project is to design a system that will utilize waste
