Building fans Combined heat and power unit
the result is impressive: At maximum heat
utilization between fall and spring, a total
efficiency of up to 87 percent, regarding
the burned natural gas, is achieved.
During the summer when heating energy
consumption is at a minimum, the heat
is released into the environment, consequently,
the degree of efficiency is
decreased. “Altogether, we expect savings
of 15 to 20 percent in the primary energy
consumption compared to today’s supply
situation,” says Klaus Gartz.
Prepared for winter
Big events have cast their shadows ahead
since fall of 2011. Back then the largescale
excavation and installation work for
the gas and local heating pipelines and
for the electrical control for the heat distribution
started on siempelkamp premises.
At the same time the company-own
medium-voltage grid was upgraded, the
new Büttner building integrated into the
electricity network and a significantly
stronger power supply line was installed
between the public power grid and the
factory building.
After completing the startup and acceptance
phase in mid-December 2012,
the combined heat and power unit is expected
to supply almost the entire amount
of electricity and approximately half of the
required heat for the company. the production
buildings take precedence, however,
other companies of the siempelkamp
Group at the location can benefit from
surplus electricity. It is also planned to feed
additional electricity into the public power
grid.
Rising energy costs demand good energy
management: It is forecast that energy
costs will further increase in the future. In
order to be prepared, siempelkamp will
introduce an energy management system
in addition to the combined heat and power
18

unit for the efficient use of electricity and
heat. Both systems will be managed by
Klaus Gartz, just as the photovoltaic
system, which was installed in 2011. the
self-sufficient operation will be ensured,
the maintenance and inspection of the
operating parameters guaranteed.
Furthermore, within the meaning of an integrated
energy concept, we will continue
to improve the use of the heat generated
by the combined heat and power unit. We
are already planning an absorption-type
refrigeration system for room air conditioning.
this system will use heating water at
105° C for cooling. “If the energy consumption
in our factory should sustainably
increase in the future, for example, due
to additional large machine tools, the installation
of another combined heat and
power unit could be worthwhile. For this
case, we have already designated a location
and heating network capacity,” says
Klaus Gartz thinking about the future.
