Brighton 'B' Power Station - Page 5
Control Room
The control room was on the centre line of the station and contained
the main 132 kV and 33 kV control panels for operating switchgear at two
substations situated at Southern Cross and Fishersgate. All main switching
and synchronising of the six generators was carried out on individual control
desks, as was the switching of 3.3 kV auxiliary supplies.
In the grid control centre directions were issued for feeding the high
voltage current into the National system.
Ash & Dust Plant
Ash from the boilers was washed by high pressure water jets to a central
collecting pit whence it was removed by grabbing crane to a storage and
drainage hopper. After draining, the ash was conveyed to a disposal point
where lorries were loaded to take it from the station.
Current from the generators was stepped up to a higher voltage by the
windings of oil-cooled transformers.
The dust handling plant was designed to remove flue dust accumulating
in the collecting hoppers of the economisers in the mechanical grit arrestors
and electrostatic precipitators of the eleven boilers, and from the base
of the two chimneys. The plant consisted of hydrovactors creating a vacuum
in a pipeline which transfered the dust from the hoppers to central collecting
bins capable of holding 2,100 tons.
The dry dust was then fed by rotary feeders to four double shaft mixers
where it was conditioned or wetted before disposal by lorry to brick manufacturers,
road builders or waste ground for levelling. Dry dust could be loaded direct
to tanker lorries for use in concrete manufacturing. With the station generating
on full load, approximately 305 tons dust and 66 tons ash were disposed
of daily.
In the substation the switchgear and its operating mechanism controlled
power flow on grid lines.
Water treatment Plant
A demineralisation plant was installed to produce high quality make-up
water from the town main supply. Raw water was fed in series through the
first two treatment units which turned all the dissolved mineral salts into
their corresponding acids, which were then absorbed. A degasifier tower
scrubbed out the carbon dioxide with a stream of air and a final unit removed
the silica and was capable of converting any neutral salts to the corresponding
hydroxide.
