Interview with Krzysztof Goclowski
Technical Production Director of Elektrocieplownia „Zielona Gora“ S.A.
What were the three key success factors of this project
for EC Zielona Gora?
Krzysztof Goclowski:
There were three very important key success factors for us:
The installation of a boiler system with the best available
technology at the best possible price, the strict compliance with
the time frame and no accidents during the construction phase
of the boiler system.
What guidelines regarding the emissions had to be
complied and who checked these values?
Krzysztof Goclowski:
In this project all current and future (from 2016) Polish and
European Emission Regulations (Directive 2010/75/UE) had to
be fulfilled.
For the NOx emissions will then apply:
Natural gas: < 100 mg/Nm3 at 3% O2
Heating oil : < 150 mg/Nm3 at 3% O2
The emission measurements were verified and confirmed by
"Energopomiar" Sp.z o.o., Gliwice, an accredited and certified
Polish organisation.
What were your reasons to decide for boilers of Bosch
(Loos) with marathon
®
burners of dreizler
®
?
Krzysztof Goclowski:
Boilers of Bosch (Loos) combinated with marathon
®
burners of
dreizler
®
guarantee all technical specifications (combustion
capacity, high efficiency, availability), emission values and a very
attractive price.
Pure Energy.
Reliable.
Efficient.
Clean.
