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 30, Figure 7 in
the installation plan should be kept for operating
and servicing.
-
These dimensions are needed 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 G160 design.
-
The optional exhaust air ventilator box can be
disassembled for installing the cogeneration
module. Please let us know before delivery.
-
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 engine shut-off valve that is 100% sealed to
exhaust gas.
-
A return temperature increasing mechanism is
needed when the heating water return
temperature is below 60 °C.
A separate return temperature increasing
mechanism should be provided with the EM-
401/549 model for the low-temperature mixed
cooling circuit.
-
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.
4.5
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 is caused by operation and is not a
defect.
4.6
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).
