Import coking coal. Rotary kiln DRI capacity has been installed because it makes use of domestic iron ore and coal but there is a limit to the growth of this technology because rotary kilns cannot be built larger than about 200kty. Thus it is probably not feasible to build a steel mill to produce 1Mty or more via this route.

Gas quality was investigated. Therefore coal was pyrolyed in a rotary kiln reactor before gasification in a dual fluidied bed steam gasifier. The results were compared in terms of gas quality and quantity for determination of the influence of the state of feedstock pyrolysis on the performance of steam gasification. INTRODUCTION
