Substitution of Charcoal for Coke Breeze in Iron Ore Sintering J

Abstract. The substitution of charcoal as an alternative fuel to coke breeze in a simulated Japanese Steel Mills (JSM) sinter blend was investigated. Compared with coke breeze, Anthracite coal as fuel for iron ore sintering is compared with coke breeze. Anthracite is lower in porosity, higher in density, and slower in combustion rate. With Effects of anthracite replacing coke breeze on iron ore sintering

Research on the Quality Improvement and

In order to increase agglomeration production and improve its quality while reducing energy consumption, a new intelligent blending method has been established at Ansteel to optimize its sinter blends. The sintering process is an important production link in the iron and steel industry, and its energy consumption accounts for about 11–16% of the total energy consumption of the industry, and the pollutants emitted by sintering account for about 50% of the total emissions of steel enterprises [1, 2].In April 2019, the Ministry of Ecology and Thermodynamics and Kinetics of Coke Breeze Combustion Under

Effect of Coke Size on Iron Ore Sintering Semantic Scholar

The coke combustion process in iron ore sintering is dependent on the coke size.Therefore pilot-scale sintering tests with blends containing different coke size distributions were carried out to investigate the effect of coke size(the ore blend contained 10% MAC marra mamba fines).It was found that increasing the coke mean size by Lime coating coke method, where coke breeze is coated with hydrated quick lime (Ca(OH) 2), has been developed in NSC to decrease the nitrogen oxide (NO x) emission from iron ore sintering machine. The Ca(OH) 2 powder coated on the coke breeze surface reacts with the iron ore fines existing around the lime coated coke Iron ore sintering ScienceDirect

Abstract and Figures. The sinter process of iron ore with biomass carbon instead of coke breeze as fuel was investigated via thermodynamic analysis in this paper through a comparison of sintersolid fuel in iron ore sintering. Reduction in consumption of primary fuel (coke breeze) without compromising on plant productivity and sinter quality would help in the operational cost reduction as well as in achieving the compliance of regulation related to hazardous emissions from sinter plants. Due to the poor availability of coke breeze inModified coke breeze distribution in iron ore sintering a novel

Influence of Sinter Parameters on CO Emission in Iron Ore Sintering

Iron ore sintering is an agglomeration process of iron ore fines, fluxes, fossil fuel (coke and coal), and some iron-bearing waste materials in the ironmaking and steelmaking industry . Sinter is one of the main raw materials used in a blast furnace (BF) accounting for more than 70% ferrous burden of BF in China [ 2 ].Coke breeze is the main heat source in sintering process. Its combustion yields enough amounts of heat which melts the sinter mix. One of the factors that significantly affect the course of coke breeze combustion is its grain size [1,2,3].It is known that fine-grained coke reduces permeability of the sinter mix and the use of coke breeze Effects of Particle Size of Coke on Iron Ore Sintering Process

Sintering: Most Efficient Technologies for Greenhouse Emissions

Minimizing the addition of −0.25 mm coke breeze, maintaining the highest combustion temperature at around 1300 °C, and keeping relatively high oxygen content in atmosphere are expected to promote combustion efficiency of coke breeze and thus energy utilization in iron ore sintering (Ogi et al. 2015).Sintering of iron ores is an enormous energy-intensive and resources consuming process. Introducing a selective waste gas recirculation (SWGR) to the sintering process reduces the energy consumption, stack gas volume flow, and sulfur dioxide emissions of an iron sinter production. Simulating this complex process in flowsheet Model of an iron ore sinter plant with selective waste gas

Sintering: A Step Between Mining Iron Ore and Steelmaking

According to the U.S. Environmental Protection Agency, the sintering process converts fine-sized raw materials, including iron ore, coke breeze, limestone, mill scale, and flue dust, into an agglomerated product, sinter, of suitable size for charging into the blast furnace.The production of crude steel in the iron and steel industry in China has grown dramatically, which has made the country the world's largest steel producer since 1996 1 3. 40%–60% of the total iron-containing burden in the blast furnace during ironmaking is sinter 4.The iron ore sintering process is one of the vital steps -in an Partial substitution of anthracite for coke breeze in iron ore sintering
