THERMAL POWER PLANT & TURBO BLOWER STATION.
( Pakistan Steel).
As
a part of project design, Pakistan Steel has its own Thermal Power Plant
(capacity 110
MW ), comprising of 3 generators 55 MW each, two stay in operation and the third as
standby. The plant also has 3 Turbo Blowers of capacity 1,600 - 2,200 N cu. m/min each and
four Boilers of capacity 220 t /hr.
Thermal Power Plant uses mostly the coke oven gas and steam from coke oven batteries (an internally
available fuel) to generate electricity and represents an
extensive energy complex of the industrial power supply with specific focus on
the needs of the metallurgical enterprise.
The turbo blowers generate large volume of air blast
(compressed air) which is supplied to Iron Making Department for melting iron ore
to produce pig iron in Blast Furnace. The compressors powered by steam turbines
are connected to electrical generators.
The above view showing, out-going pipe lines of compressed
air to Iron making department & in-coming gas and steam pipe lines from
Coke oven to T.P.P.& T.B.S.
Due to continuous running
of TPP & TBS, an internal wear & tear result to the turbo blowers, steam
turbines, bearing blocks, stators, rotors and casing of generators. Most of the repair and maintenance work of
turbo-machinery components & generators and associated insulation and
cladding work of boilers is carried out internally by Pakistan Steel with the
help of repair shop complex of Central Maintenance Department and Refractory
repair department.
