MLADÁ BOLESLAV PLANT
SUCCESSFULLY FIGHTS LIGHT
sky full of stars is an amazing but increasingly rare sight. Just a few decades ago, over 3,000 stars were usually visible on a moonless night. Today, you
can hardly make out 400 on a city’s outskirts. The reason is an effect called light
pollution. Its rate is determined by the nine-level Bortle scale. One means perfect
darkness – not just stars but also distant
galaxies can be seen with the naked eye.
At the opposite end, nine is common in
the centre of Prague and elsewhere –
the sky is so bright that a less experienced eye would not even recognise well-known constellations. We no longer
experience level one in the Czech Republic today. Most of the territory is at a five
and higher. However, there are three exceptions where it is possible to observe
astronomical phenomena. The nearest
one is located near Jizerka, a settlement
in the Jizera Mountains.
The largest sources of light pollution
are unshielded street lamps. Illuminated
buildings at a wrong angle and advertising
and entertainment lighting also contribute to the pollution. And as any other kind
of pollution, the light pollution is bad for
your health: You sleep less well, you are
prone to depression, and research has also
shown that it has an influence on obesity.
Therefore, at selected locations in the Mladá Boleslav plant, the PSZ/4 – Service and
Infrastructure Operation department has
replaced a total of 148 old and unsuitable
street lamps with new LED lights that do
not disturb. The new lamps are used at the
M1 test track, on the main street nicknamed Václavák in the old plant and on some
roads, such as at Rolnická škola. The replacement has not only decreased light pollution but also saved about 30 percent
of electric power, almost 80 MWh a year.

CENTRAL TECHNICAL SERVICE PUTS A COUPLE OF ECO-FRIENDLY
BOILERS INTO OPERATION IN THE KVASINY PAINT SHOP
hanks to modern technologies in
the Paint Shop, the PSZ – Central Technical Service department
contributes to lowering the production
of CO2 and other harmful substances in
the Kvasiny plant, bringing the carmaker
closer to its goal of carbon-neutral production. Emission reduction and financial savings come from two newly installed burners that are part of the thermal
emission control device, replacing the
original ones that had been in continuous operation for 18 years. Specifically, they are thermal afterburners (TNV),
which are used for the afterburning of
VOC emissions. The resulting hot air is
used to heat car bodies. “Their proper
functioning ensures that the lines are
working and the entire Paint Shop is running”, explains Lukáš Bartoš from PSZ.
The Paint Shop depends on heat from
the afterburners and cannot afford an interruption. It is the most critical bottleneck in production, and if stopped, the
entire factory production will cease very
“The planning regarding future replacements took over a year. We had
to prepare each step in meticulous detail so that everything went according to
plan. The whole process could be described in three fundamental stages: preparing the space (we chose a completely
new location for the electrodisposition
afterburners), moving the equipment to
the building (which, among other things,
made it necessary to open the roof
structure in order to bring it in) and connecting and commissioning the equipment”, describes Bartoš.
One burner instead of two
In cooperation with local maintenance services, the PSZ department managed to install more efficient devices.
The innovation made it possible to
shut down the existing pre-electrodisposition (ED) oven, creating a modern
shop floor with the most significant
change on the ED coating line, where
the device can do with just one burner.
In the original boiler, one burner was
used to heat the air for the pre-oven
space, which prevents thermal shocks,
and the other prepared the air for a higher temperature for the actual oven.
Today, different temperatures are provided by the exchanger, which increases the overall operation efficiency.
“We will see tangible savings only after a year”, Bartoš explains, adding
that the expected reduction in gas and
electricity consumption is already significant. LUDĚK VOKÁČ
