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

Pulverized coal injection (PCI) is a well-established technology for hot metal (HM) production in a blast furnace (BF). It is practiced in most of the BFs and all the new BFs are normally built with PCI capability. The composition and properties of the coal used for injection can influence the operation, stability and productivity of the BF, the quality of the HM, and the composition of the BF gas. The coals being used for the PCI are described in the article under link ‘http://www.ispatguru.com/coal-for-pulverized-coal-injection-in-blast-furnace/’.

The critical aspects of PCI systems include coal preparation, its storage and distribution to ensure uniform feed of coal to each tuyere without fluctuations in the coal delivery rate and its combustion through lance design and oxygen (O2) injection.

Stainless Steel Hoses are 100% quality checked and tested since it is manufactured by the latest well-equipped CNC machinery and latest techniques like cutting and bending and for any other structural flaws by our highly qualified professional staff according to Indian and international industry standards guidelines.
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. Furthermore, the amount of coke used can be reduced if huge amounts of pulverized coal are injected. Therefore, in recent years, Pulverized Coal Injection (PCI) systems are used in order to lower production costs as well as extend the life cycle of coke ovens.
