PCI+®-Pulverised coal injection

PCI+® S is characterized by:

main conveying pipelines to static distributor with injection pipelines based of dense stream technology
minimum wear and tear due to low conveying velocity
high availability of the PCI+® S installation (more than 99 %)
high specific conveying flow rate (more than 400 kg/cm²/h)
troubel-free adaption to the blast furnaces due to small inner diameters of the injection pipelines (12 - 26 mm)
Erection of the PCI+® S installation in high distance from the blast furnace (length of the main conveying pipeline up to 700 m)

PCI+® V is characterized by:

Multiple dosing of pulverized coal from fluidized bed for uniform distribution over all injection pipelines
Minimum wear and tear due to low conveying velocity
High availability of the PCI+® V - installation of more than 99 %
Very high specific conveying flow rate of more than 650 kg/cm²/h
Trouble-free adaption to the blast furnace due to small diameter of the injection pipeline (12 - 26 mm inner diameter)
Erection of the PCI+® V - installation in sufficient distance from the blast furnace (length of injection pipelines up to 150 m)
Low nitrogen load of the blast furnace by PCI (10-20 Nm³/t injected pulverized coal)

PCI+® VC ist characterized by:

Vessel-distributor with single independent conveying pipelines based on the dense-phase pneumatic transport
Multiple dosing of the pulverized coal out of a fluidized bed for equal distribution over all conveying lines
Extreme small specific conveying rates possible (from 30 kg/h per single conveying pipeline)
Minimal wear by low conveying velocities
High availability of the PCI+® VC - equipment (nearly 100 %)
Extreme high specific conveying rate (more than 650 kg/cm²/h)
Uncomplicated adaptation to existing Cupolas by small diameter of the single conveying pipelines (10 - 14 mm internal diameter)
Erection of the PCI+® VC - Silo and intermediate conveying plant in large distances of the vessel-distributor (up to 500 m)
Small required space for the vessel-distributor near by the Cupola
Ultralow nitrogen - input into the Cupola (10 - 15 Nm³/t oulverized coal)
Use of various pulverized coals and coal mixtures
Use of Oxycoal lances for complete coal combustion
