Abstract:
Several sources of biomass have been used in the energy and chemical industries. The use of biomass to reduce greenhouse emissions is a promising technique due to the short recycling of carbon in the environment based on photosynthesis natural process.
The partial use of elephant grass charcoal (EGC) on iron ore sintering plant is an ecological solution to reduce the consumption of fossil fuels in this process and simultaneously attain the physical and metallurgical properties of the sinter product. The advantage of elephant grass compared to another biomass source is its high productivity, high mechanization of the plantations and utilization of poor soil (degraded) with small amount of chemical fertilizer.
In order to replace anthracite (ANT) by EGC, it is necessary to use a mass substitution factor (MSF) to keep thermal energy supply in the process due to its lower calorific value compared to the fossil fuel.
In this experimental study, 25% of CB is replaced in the sintering process by EGC using the MSF of 1.45. The results were compared to a standard operation of 100% of fossil fuel based on the chemo-physical properties of sinter product. The results of the sinter properties obtained in this study on the pilot sinter plant for 25% of EGC were compatible with the standard operation.
