Impact of biofuel in agglomeration process on production of pollutants

Abstract

Production of agglomerate in the metallurgical company belongs among the largest sources of emissions damaging the environment. Effects of coke breeze substitution by charcoal, pine, and oak sawdust there were sintering performed in a laboratory agglomeration pan with substitution ratios of 14 % and 20 % by the emissions of CO 2 , CO, NO x and NO. Variations in the gas emissions might have been affected by physical and chemical properties of the input materials and the technological parameters of agglomeration. It is important and necessary to seek other methods and materials with which it would be possible to optimize the production of emissions and protect the environment.

Utilization of the prepyrolyzed technical hydrolysis lignin as a fuel for iron ore sintering

“…The effect of replacing part of solid fuel during sintering with various biomaterials is investigated. Accordingly, the study [11] of the effect of replacing coke breeze with charcoal, pine and oak sawdust is carried out. It is shown that when using sawdust materials as a solid fuel, considerable fluctuations in the process parameters are observed.…”

The Anthracite as Sinter Fuels

“…Production of agglomerate in the metallurgical company belongs among the largest sources of emissions damaging the environment. Effects of coke breeze substitution by charcoal, pine, and oak sawdust there were sintering performed in a laboratory agglomeration pan with substitution ratios of 14% and 20% by the emissions of CO2, CO, NOx and NO (Lesko et al 2017). Researchers in Asia (Jiang, T., et al 2010) are introducing a completely new method, known as CAP, where it involves total or partial separation of ores (8-16 mm) in a drum and the remainder of the ore is pelleted after the first mixing with the return of the return sinter fines, fuel and additives.…”

The effect of temperature, time of curing and Na2O/SiO2 molar ratio on mechanical and chemical properties of geopolymer cement

“…The production rate of Portland cement is at approximately 3000 Mt/year [3], and about 13500 million tons of CO2 are released in the atmosphere from this process worldwide. The main greenhouse gas is CO2, which has an essential role in increasing global warming [4][5][6]. Due to the increasing temperature around the world, greenhouse gas emissions are an  Corresponding author: Masoud Rajabi, m.rajabi@eng.ikiu.ac.ir environmental issue, and the cement industry has an important role to play in their reduction [5,7,8].…”
