partial substitute for expensive coking coals by assessing coal fines reduction, coal blend cost analysis, extended coke production and coke quality. At the optimum condition of adding 6.0 wt.% carbonisation tar, key coke qualities were improved. This occurred even when lower quality coking coal of up to 35% was included in the coal blend.

Author Posts June 25, 2013 at 3:19 am #1629 Freddy Martinez Participant We are facing high generation of fines in our new coker unit. High geneartion of fines of the order of av 30-35% ( less than 1.18 mm partical size) is ...
the values of -1mm fines generated range from 8% to 28.5% for different samples. The fines ge-nerated will have to be screened out before the use of sponge iron in electric arc furnace. Thus, the profitability of the process is dependant on the extent of fines generation. Besides affecting the economical viability,

14-01-2005· Dear All, I am handling lime now through conveyor system.I am asked to calculate generation of fines due to drop of about 3m. I do not know how to calculate the same. Kindly help me in this regards.The data in respect of lime are as below; 1. size,mm.....10 t0 40 2.Bulk density t/cu. m.....1.0 3. Max. temp. of KILN to produce,deg..... 1000 C 4.Strength of lime.
25-06-2013· We are facing high generation of fines in our new coker unit. High geneartion of fines of the order of av 30-35% ( less than 1.18 mm partical size) is observed not all the time but in some specefic crude blends processing.
09-03-2013· Sintering is a thermal process (carried out at 1300 deg C to 1400 deg C) by which a mixture of iron ore, return fines, recycled products of the steel plant industry (such as mill scale, blast furnace dusts, etc.), slag forming elements, fluxes and coke fines are agglomerated in a sinter plant with the purpose of manufacturing a sintered product of a suitable chemical composition, quality ...
• Conveying and sieving: enclose potential dust sources, and filter evacuated gases. ... New coke plants should not generate more than 1 kg of process solid waste (excluding coke breeze and biosludges) ... fines should be recycled to coke ovens. Waste-
If FeO is more, sinter will become more brittle, causing more fines generation & cause for continuous furnace hanging and increases coke rate in blast furnace. If FeO is less, sinter will be weak causing more fines generation & leading continuous to furnace hanging So, FeO should always be optimum.
01-06-2019· Production of coal fines in coke making has lately become a problem worth addressing due to its negative impact on ecosystems. The use of coal fines is becoming an issue due to high Quinoline Insoluble formation during the carbonisation process as well as carry over or enhancement of carbon deposition in the upper parts of the coke ovens.
【Abstract】 <>The behavior of fine coke generation during the drum test was investigated considering the coke breakage mechanism.Change in fine generation rate,its Weibuil analysis and size distribution of fines were examined.Coke fines after the drum test were divided into the following three classes: (1) Under 0.5mm fines generated by compressive breakage of coke matrix.
Fox Venturi Eductors are used for pneumatic conveying of coke fines in dilute phase systems. Is a maintenance-free pneumatic conveying solution of interest at your plant? Fox venturi eductors are installed in hundreds of cement, co-generation, and waste-to-energy plants conveying …
Oct 31, 2000· This minimizes the generation of fines due to attrition and should enable the fines, which might have been generated by the conveying process, to escape from the system. The alternative case is that the cyclone loss rate must be minimized in order …

The current concept is for coke produced at the SEP site to be crushed to a top size limit of 100mm, screened to remove fines then loaded into standard Blackwater train consists of approximately 4,200 tonnes of coke. Coke fines generated at the site may be used in power station feedstock or recycled back into the coke oven charge.
