Type of CHP system: Anaerobic digestion
Plant owner: The GF-Bio-Energie Hasetal in Löningen is a limited liability company with 3 owners.
Status of plant: Commercial
Contractor details: SCHMACK Biogas AG (type EUCO S5, discharge-digester: EUCO 400)
biogas CHP units: Schell
Power generation: Gas engine
Main fuel: Biogas
Nominal capacities & efficiencies:
Gross electrical output: 0,8 MWe
Net electrical output: 0,767 MWe
Electrical efficiency, gross: 35 %
Gross-heat capacity by full load: < 28 MJ/s How is plant controlled: The biogas plant generates a maximum of electricity to feed into the public grid and is limited by the amount of arising biomass input material.
Heat usage: Heating only
Energy usage: Process heat for digester: 3 109 MWh/a
Fuel storage: The biomass plant storage building has a capacity of max. 1000 m³.
The biogas plant in Löningen consits of 10 x 80 kWh CHP units, 2 laying digesters of 400 m³ each and 5 downstream storage digesters of 1800 m³ each. The company uses only liquid manure, renewable primary energy products and vegetable waste to produce biogas. Two of the company owners run also a liquid manure stock market.
Fuel feeding system: Mechanical loading system
Digester capacity: 7130 m³
Residence time: 28-35 days
Process temperature: mesophilic (40°C)
Annual gas production: 32000 Nm³
Gas quality: 54 % methane
Engine: pilot injection engines a’ 80 kW (35% efficiency)
Flue gas cleaning:
Dust removal via fabric filter system
HCL reduction by flue gas scrubber
NOx-reduction via selective catalytic reduction (SCR)
SO2/SO3 reduction also by flue gas scrubber
one-level process; wet-fermentation (dry substrate content: 7 %)
The plant produces appr. 50 000 t fertilizer per year, which is used in agriculture and forestry.
Staff: Appr. 2 full time persons
Electricity sale info:
The German biomass-CHP plants, which feed the generated electricity into public grid, get a fixed amount of allowances per kWh (according capacity and year of commissioning) by legal restrictions – EEG -. This allowances decreases every year.
