Petroleum coke also known as petcoke is a byproduct of the refining process of crude oil It is a carbon rich solid material that is used for various Anodes Production Needle coke is used to produce the electrodes used in electric arc furnace EAF steel production No other material has needle coke s combination of electrical
Thus for shaft furnaces operating on solid fuel it is necessary to attempt to reduce the height of the high temperature zone This can be done by using fuel which has a low reactivity in relation to carbon dioxide such as a fuel based on petroleum coke or is of reduced coarseness which ensures an efficient distribution of the air blast
The results show that the vertical shaft furnace is a self sufficiency equipment without additional fuel required but the overall exergy destruction accounts for % of the total exergy input In addition the energy ous reacting flow of petroleum coke calcination in the shaft Moreover Elkanzi [10] adopted a
In the context of reducing greenhouse gas emissions and achieving carbon neutrality the steel industry is rapidly developing towards a low carbon hydrogen metallurgy path and the hydrogen based shaft furnace direct reduction route which has lower CO2 emissions compared to the conventional blast furnace route is now receiving widespread attention This

Vertical shaft furnace for calcination is quite different from rotary kiln for calcination in the principle of calcination process calcined coke quality product availability production capacity
thermally desulfurized in a shaft furnace since the work by Edwards [13] found that such cokes give better results than those calcined in a rotary kiln Particle gas contact is important for hydrodesulfurization and thus tests need to
The partial substitution of petroleum coke with alternative solid fuels such as biomass is advantageous for mitigating greenhouse gases and energy consumption in cement production furnace performance and the influence of biomass co combustion on combustion properties species emission and unburned Carbon in ash [5 6 7] This research
Within the coke making industry the ability to accurately predict the quality of the coke produced from a variety of global coal basins is critical in both coal selection and blast furnace control
GPC green petroleum coke Rotary kiln calciners are widely used for CPC production in the world while the vertical shaft calciners are used in most Chinese CPC plants Vertical calciners are stationary calcining furnaces The technical and economical comparisons between the rotary calcining and the old vertical shaft calcining technologies are
In recent years the reformed coke oven gas COG was proposed to be used as reducing gas in a shaft furnace A mathematical model of gas flow based on the reformed COG was built The effects of the pressure ratio of reducing gas to cooling gas k on the gas distribution in the shaft furnace were investigated The calculation results show that k is an
This study reported the development of an advanced shaft furnace which improved the conventional waste gasification system and evaluated its performance using operation data and gasification criteria such as cold gas efficiency carbon conversion ratio lower heating value emissions slag quality and heavy metal distributions The coke consumption of
The blast furnace is a tall vertical shaft furnace which uses coke to reduce iron ores The product a hot metal which is impure iron is suitable as feed material for steelmaking There are different charging systems for BF discussed in detail
process the shaft furnace/electric furnace short process can reduce CO 2 emissions by about 1/3 [2] Among them the MIDREX and ENERGIRON processes are impor tant technologies for shaft furnaces and DRI produced by shaft furnaces using these two technologies account for and pct of world direct reduced iron production
