Power station gets new gear units on the quiet September 1st 2010 New Flender FZG gear units
from Siemens Industry are
proving their worth at E.ON
UK's Connah's Quay combined cycle
gas turbine power station on Deeside.
Originally 40 gear units, all Flender
FZGs (size B2SV10), were fitted in
1994 for the cooling tower fan units at
the power station.
The power station is adjacent to a
residential area, so noise levels have to
be minimised, and the original fans
featured noise-attenuating baffles.
However, these made them inaccessible
for maintenance – at 9.2m
across and weighing 2.5t, each fan
would take 4-6 weeks to dismantle if a
gearbox needed maintenance. A
decision was therefore taken to install
quieter fans and gearboxes, allowing
removal of the baffles to increase
airflow and improve accessibility
The improved specification units
supplied from the Siemens factory in
Penig, Germany, were specially
enhanced to reduce noise, and are
significantly quieter than the original
units supplied in 1994. The 20 new
units were also fitted with 132kW
inverters, and new, quieter fans were
fitted to the cooling towers. More articles from Siemens Industry Automation & Drive Technologies (Flender): |
