A study on the accretion formation in DRI kilns and

Jan 11, 2016 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 accumulation of semi-molten material which form rings along kiln lining. These rings narrow the kiln diameter thereby hindering efficient material flow and effect lowering production rate and performance of the kiln. A study on the

PDF A study on the accretion formation in DRI kilns and

Direct reduction of iron ore with aid of either carbon or natural gas under controlled temperatures and pressures within a rotary kiln generates sponge iron as a product. However rotary kiln performance is adversely affected by the ring formation known as accretion. These accumulated sintered solid particles which gives formation of ring along the length of the kiln hinder material flow, lowers the

A Case Study on Accretion Formation in Rotary Kiln of DRI

Nov 13, 2020 Accretion formation in a rotary kiln of 100 tpd DRI plant has been investigated. The nature of accretion formation with respect to the charge burden and operational parameter have been discussed. High ash content in the coal and excess use of dolomite lead to accretion formation. Two different types of accretion are revealed the major one is due to agglomeration of DRI by-products while another one is sintered product of
