Tecnored process - high potential in using different kinds of solid fuels

one important feature of the brazilian tecnored ironmaking process is its flexibility to use different types of solid fuels, other than metallurgical coke, as proved in the pilot plant tests by extensively using green petroleum coke, biomasses, high ash cokes, etc. even if new solid fuels not thus far used are envisaged for a given project, thru the bench scale simulator of the process it is possible to predict the behavior of such solid fuels in the tecnored furnace and establish the best techno-economical-environmental equation for its use. this paper discusses the key aspects involved in the use of alternative solid fuels in the tecnored process.
