Our products

Product category: Pneumatic conveyors

PCI+® S - Injection of pulverized-coal

Injection of pulverized coal into the tuyères of blast furnaces using a static distributor

PCI+® S is characterized by:

Main conveying pipeline to static distributor with injection pipelines
Minimum wear and tear due to low conveying velocity
High availability of the PCI+® S installation of more than 99 %
High specific conveying flow rate of more than 400 kg/cm²/h
Troubel-free adaption to the blast furnaces due to:
- Small diameter 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)

Product category: Pneumatic conveyors

PCI+® VC - Pulverized Coal Injection

Injection of pulverized coal into the tuyères of a Cupola by means of a vessel-distributor.
PCI+® VC is 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

About us

Company portrait

The E.S.C.H. GmbH was set up in 1992 to apply existing expertise in pneumatic conveying technology in iron and steel industry, to develop new processes in order to transfer them to other industrial branches. Since this time the E.S.C.H. GmbH has been commissioning different dosing, injection, absorbing and transportation plants on blast furnaces, converters and electrometallurgy workshops, aluminum melting aggregates, and other industrial plants. The main technological targets of the designed facilities are the improvement of the environmental impact by absorbing toxic contaminants from exhaust gas as well as the reduction of the costs of production by saving of raw materials and substitution of oil and gas with alternative solid fuels.
