1. The effects of hydrogen fraction in co-injection gas on combustion characteristics of the raceway in low carbon emission blast furnace are studied.
2. Increase of hydrogen fraction promotes the pulverized coal burnout and improves the prediction accuracy of temperature fields.
3. Combustion, gasification and water-gas shift reactions play conjoint roles in the redistribution of reducing gas species.
The article is generally reliable and trustworthy, as it provides a detailed analysis of the effects of hydrogen fraction in co-injection gas on combustion characteristics of the raceway in low carbon emission blast furnace. The article is well-researched and provides evidence for its claims, such as citing relevant studies and providing numerical results from simulations. Furthermore, it does not appear to be biased or one-sided, as it presents both sides equally and does not promote any particular point of view. However, there are some points that could be improved upon, such as exploring counterarguments more thoroughly or providing more evidence for certain claims made. Additionally, potential risks associated with this technology should be noted to provide a more comprehensive overview.
