Low-Carbon Production of Iron & Steel: Technology Options, …
— BF-BOF operation relies almost entirely on coal products, emitting ~70% of CO2 in the integrated plant (BF iron making). Hot iron is then charged to BOF to make steel HM (BOF steel making). An integrated BF-BOF production plant also include process plants for coking, pelletizing, sinter, finishing, and associated power production.
Raw materials
To make steel in a blast furnace, coal must first be turned into coke. Coke has a dual role in the steelmaking process. First, it provides the heat needed to melt the ore, and second, when it is burnt, it has the effect of 'stealing' the oxygen from the iron ore, leaving only the pure iron behind. In the coking plant, coal is heated in the absence of oxygen to 1250c.
Industrial perspective of the cokemaking technologies
— The model also estimates the coke CSR at coke plant scale. The designed coal blend is directly implemented in the coke plant. It is clear from Fig. 8.15 that the CCP-based coal blend model is better than the old coal blend designing process (Tiwari et al., 2013, Tiwari et al., 2014e, Tiwari et al., 2015a).

It is useful than both for management and cash-flow monitoring purposes at operating stages. Investors putting money into power generation projects expect an appropriate …
Coal to Make Coke and Steel
— Metallurgical coal (also called "met" coal) is an important raw material used in the steel-making process, although very small amounts of coal (relative to the amount used for electricity) are needed. The coal used to make steel is heated without air in an oven at temperatures of as much as 2,060°F (1,125°F), until most of its volatile matter is released.
Advanced Coal Technologies
However, when a portion of the energy from burned coal is diverted from making electricity to carbon capture and storage using current technology, efficiency is projected to drop to about 30%, slightly below average for today's coal-fired plants. Another advanced coal technology is coal gasification, a process in which coal is converted to a ...
How a Nuclear Reactor Works
In most power plants, you need to spin a turbine to generate electricity. Coal, natural gas, oil and nuclear energy use their fuel to turn water into steam and use that steam to turn the turbine. Nuclear plants are different because they do not burn anything to create steam. Instead, they split uranium atoms in a process called fission.
A review of ironmaking by direct reduction processes: …
— Blast furnace ironmaking requires separate coke making and sintering plants and often has reduced operating flexibility (Lu, Pan and Zhu, 2015). Coking coal is regarded as premium quality coal that attracts relatively higher cost and there are concerns over the limited reserves (Chukwuleke, Iiu-ju and Chukwujekwu, 2009).
