Pulverized coal injection method - Wikipedia

Pulverized coal injection is a method for improving the performance of a blast furnace.. Background. Iron is a metal which has fundamentally affected the way of life of human beings ever since the Iron Age.It is relatively abundant and can easily be extracted and modified due to its useful material properties, all of which results in low prices.


12.2 Coke Production - US EPA

12.2 Coke Production 12.2.1 General Metallurgical coke is produced by the destructive distillation of coal in coke ovens. Prepared coal is heated in an oxygen-free atmosphere (–coked–) until most volatile components in the coal are removed. The material remaining is a carbon mass called coke.


THE BLAST FURNACE - IRON PRODUCTION - Technology Student

Blast furnaces are used continuously and are only shut down when their brick lining needs replacing. As the mixture of iron ore, coke and limestone heats, the hot waste gases are collected and cleansed. They are then used to help heat the air blast, required if blast furnace is to reach the high temperatures needed to produce molten iron.
