Turbo-сompressor units for air supply to blast furnaces (TCU) are technologically advanced products from the point of view of production capacities and technologies. These TCU are stationary, with a long service life, good maintainability.
Purpose and field of application
The turboсompressor units are designed to compress air enriched up to 40% by oxygen and to feed it to the blast furnace.
TCU component parts
The TCU includes a centrifugal or axial compressor, steam turbine drive, instrumentation and AMCS. All the equipment is developed and manufactured by Close Co. “REPH”.
