Installation

You can find detailed instructions on design in the
"Natural Gas Block-Type Thermal Power Plant Series
– Project Management" and in the relevant assembly
instructions.
You have to bear the items below in mind for installing
the cogeneration module:
-
A blocked clearance as per page 27, Figure 6 in
the installation plan should be kept for operating
and servicing.
-
Make sure at on-site installation that the module
bases are unscrewed to a clearance of at least 9–
11 cm.
-
These dimensions are needed up to a simple pipe
length of 10 meters; otherwise, it will be necessary
to make a separate calculation.
-
We recommend dimensioning the gas connecting
lines for the block-type thermal power plant to use
this lane as buffer storage. This can be used to
intercept fluctuations in pressure with boiler
circuits.
-
We recommend using a calibrated gas meter with
a G25 design.
-
The exhaust air ventilator box can be
disassembled for installing the cogeneration
module. Please let us know before delivery.
-
The exhaust air can be carried away on all sides
of the exhaust air ventilator box. The connecting
sleeves for conducting the exhaust air can be
mounted on the specific point.
-
It should not drop below the dewpoint in the
exhaust gas system. Any condensate
accumulating should be continually drained. A
water reservoir should be provided on the
condensate output.
We recommend separate exhaust gas conduction
for every cogeneration module with multiple
module systems. If you use a collecting exhaust
gas line, it is necessary to reliably prevent the
exhaust gas from flowing back into any
cogeneration modules not in operation with an
26 ESS Energie Systeme & Service GmbH
engine shut-off valve that is 100% sealed to
exhaust gas.
-
Condensate flows out of the cogeneration module
when starting in the cold state. Neutralisation is
not necessary due to exhaust gas purification in
accordance with ATV A251 (Nov. 1998). A water
reservoir (siphon loop) should be provided with an
effective water column height corresponding to the
exhaust gas system pressure (a maximum of 150
mm WS) to keep the exhaust gas from flowing out
through the condensate drain.
-
The exhaust gas condensate should be disposed
of in accordance with applicable regulations.

Start-stop ratio

The module should be at least 120 min in operation
per start (approximately 2:1 ratio of the number of
operating hours to the starts).
Early wear and tear in the starting equipment from
shorter times are caused by operation and are not a
defect.

Ecotax in Germany

You have to register your block-type thermal power
plant with your main customs office before starting it
up in Germany so that your block-type thermal power
plant can be exempted from the petroleum (natural
gas) and electricity tax. This provides a substantial
improvement of 10%-35% in economic efficiency.
Metering equipment may be required for this.
NOTE
All electricity generated in Germany via
cogeneration has been supported since
January of 2009 (2009 Cogeneration
Law).
