It is of great significance for cleaner production to substitute bio-energy for fossil fuels in iron ore sintering. However, with the replacement ratio increasing, the consistency of heat front and flame front is broken, and the thermal utilizing efficiency of fuel is reduced, which results in the decrease of yield and tumble index of sinter. Circulating …
The experiment involving ammonia injection was conducted to minimize solid fuel consumption and carbon emissions during the sintering process of iron ore. The sintering bed temperature, sintered ore quality, combustion efficiency, and pollutant emission under different ammonia injection concentrations and coke ratios were …
