1.1
Continuous output in parallel operation
Refer to pages 22-25, Tables 6 and 7 for outputs and
efficiency
The outputs and efficiency satisfy the requirements of
the standards ISO 3046/1 at 25° C air temperature,
100 kPa air pressure (up to 100 m installation height
above sea level),30% relative humidity and methane
number 80 and reactive factor cos phi = 1. The
tolerance for all efficiency, heat output and energy
applications is 5%.
All other data for the cogeneration module applies to
parallel operation. You are receiving the data for the
partial load range for the purpose of information
(although there is no guarantee corresponding to ISO
and DIN).
Only use natural gas fuel that is acceptable in
accordance with DVGW Directive G260, 2nd gas
family, group L. You can get all of the data needed for
other gas quantities and installation conditions at your
request.
Current characteristic number
The cogeneration module is a series product in
accordance with the Gas Equipment Directive without
heat dissipation equipment.
The current characteristic number is defined as the
quotient of the electrical output divided by the heat
output as per the AGFW FW308 worksheet. The figure
in Tables 6 and 7 (pages 22-25) is in the defined range
between 0.5 and 0.9 for internal combustion engine
cogeneration systems.
Primary energy factor ENEV 2007
The primary energy factor (abbreviated »fp«) gives the
ratio of primary energy used to final energy released
and this factor not only includes energy transformation,
but also transport. In other words, that means that the
lower the primary energy factor is, the better it is for
ascertaining the annual primary energy needs. The
fewer resources utilised by the form of energy used
and its transformation, the lower the primary energy
factor.
Primary energy savings in accordance with the
EU Cogeneration Directive
The level of primary energy saved is the percentage
savings of fuels with combined power and heat
generation within a cogeneration process in relation
to the fuel heat consumed in reference systems of
non-combined power and heat generation.
The calculation formula is defined in Appendix III of
the EU Directive 2004/8/EG on promoting
cogeneration geared towards available heat needs.
1.2
Stand-by operation
Charged gas-fuelled engines are only suited for use
in stand-by operation to a limited extent due to their
characteristic torque curves (on request if
necessary).
The hot water return temperature may not be in
excess of 65° C either in stand-by operation or
parallel operation.
The stand-by operation function is not in connection
with operating an absorption refrigerating machine.
1.3
Emissions of pollution
The following emission values after the exhaust gas
purification system refer to dry exhaust gas at 5%
residual oxygen content.
Emission values
NOx content measured
as NO2
< 500 mg/Nm³
