power unit with associated electricity and
heat recovery systems. thus, we achieve
higher energy efficiency and power supply
security,” says Klaus Gartz, as Manager
electrics responsible for the energy
man agement at the machine factory. this
project was made possible by an investment
of approx. 2.4 million euros at the
Krefeld location.
It is planned to generate up to 2.0 MW of
power for in-house use as well as heat for
the production halls and office buildings.
natural gas will be used as fuel for now.
Alternatively, the system can be converted
to bio gas according to the Renewable
energy sources Act later on. the main
component of the new siempelkamp
combined heat and power unit is a gasoperated
gasoline engine (otto engine),
which drives a generator to produce power.
Isolated operation ensures energy
autonomy
the electrical energy is directly fed to
the on-site medium-voltage switching
facility at a 10 kV level and supplies, via a
medium-voltage power network, a total

Combined heat and power units, cogeneration of heat and electricity & co.: Mini-Lexicon
Combined heat are used in Germany for decentralized power generation while simultaneously using exhaust heat. they
and power units: are predestined to lower the primary energy demand and Co emissions. A gas-operated combined heat
2
and power unit generates heat and electricity at the same time (cogeneration of heat and electricity). Its
capacity is designed for use in businesses and housing areas.
Cogeneration of kills two birds with one stone: on the one hand, mechanical energy is generated which, most of the
heat and electricity: time, is directly converted into electrical power. on the other hand, useful heat for heating purposes or
for production processes (process heat) is produced. this concept utilizes the used primary energy with
significantly higher efficiency than the separate generation of electricity and heat.
Combined heat and effective since 2002. By promoting the combined generation of electricity and heat in order to save
power generation act: energy, the legislative body aims to contribute to environmental protection and climate protection objec tives.
It is planned to increase the share of combined heat and power generation to 25 percent until 2020.
Otto engine: ivery common in combined heat and power units; the four-stroke engine from automotive engineering
was modified for this application. the gas engine presents a special option: While traditional otto engines
are operated with liquid fuel, the gas engine for combined heat and power units is operated with natural
or bio gas.
