This study investigates the sintering behavior of iron ore and its modification regarding the conventional and alternative fuel delivery systems. The modification aims to find an established alternative source of fuel for sintering which would be greener and cleaner. In the process, it will additionally facilitate the development of sustainable technology for cleaner production. The novel strategy mentioned here depends on biomass for heating and reduction purposes. Even though biomass is yet to be validated as a fuel source, there have been widespread research activities across the globe on its usage and efficacy as an alternate fuel source. Previously, several experiments failed in developing the desired quality of sinter by complete substitution with biomass. In the present study, sintering was carried out with variable proportions of biomass and coke to seek out the optimum quantity of biomass that could effectively replace coke. It succeeded in replacing coke by 10% of sawdust, 30% of wood charcoal, and 30% by a combination of sawdust and charcoal. The temperature-time profile indicated the potential of charcoal to generate the maximum temperature in the shortest interval. An opposite response was recorded in the case of sawdust. Coke was found to generate a relatively lower temperature in a relatively long period as compared to charcoal. Sinter reducibility and strength properties were also examined during the present study to determine the technical feasibility of the suggested method.
