摘要：This paper describes three operating biogas plants with
a comparable electrical power of 600 kW. The plants are situated in
Germany and were constructed between 2007 and 2013. They belong to
one owner who has a farm with an area of ca. 1,200 ha, oriented towards
plant production. The article presents technological solutions applied in
biogas plants; an attempt was also made to determine their effect on the
amount of electricity consumed in the process (operation of stirrers,
substrate feeders, pumps, control systems, lighting, etc.). Despite similar
electrical power, the biogas plants differ in terms of construction and
technological solutions. The differences stem mainly from the number and
capacity of digestion chambers, the method of biomass stirring and the
method of substrate supply. The preliminary conclusions from
observations of these facilities confirm the literature data concerning the
consumption of electricity in the process compared to total electricity
production. The paper also presents the capacity factor for each facility and
the level of heat use from cogeneration.
