Pulverization characteristics of coal affected by magmatic ...

The particle size distribution of the coal samples reflects the pulverization degree of the coal to some extent. To study the pulverization characteristics of the coal samples obtained from the field, we measured the particle size distribution. The test results are shown in Table 1. Three groups of screening results of the pulverized coal ...

Pulverized Coal Injection (PCI) System for Blast Furnaces ...

Pulverized Coal Injection (PCI) System for Blast Furnaces. In the past, reactions within the blast furnace were stimulated by injecting heavy oil, as auxiliary fuel, along with the blasts and oxygen. The heavy oil was replaced by pulverized coal after the oil crisis. This made it possible to use cheap coal, such as non-coking coal.
