Heating System


use of stainless steel

6 m pipes bent on radius and welded on site

very stable – wall thickness > 2 mm

resistant against stones and other contaminants

Attachment to the digester inner wall (most efficient heat transfer to the substrate)

Arrangement approx. 1,2 to 1,5 m over bottom

No lowering of heat input by

– sedimentation

– sink layers

No heat stresses due to a floating bearing

Stainless steel can conduct heat approx. 40 x better than PE

No substrate adherence due to a max. flowtemperature of 65 °C (automatic control)

Wärmeleistung TLD ohne Iso Wärmeleistung TLD mit 4 cm Styrodur Wärmeleistung Decke mit 10 cm Styrodur

Beispiel: 6000 m³ slurry, 1000 t solid manure; Digester 16 x 6 m; location: Eifel (colder region in west germany)


AGITATING CONCEPT


Choice of agitator technology depends on severalrequirements

Substrate (dry matter, viskosity,..) Dimension of tank Pobability of floating an sink layers Customer request: internally or outboard

engine

Choice by ÖKOBIT of energy-optimised agitatortechnology with stirring reserve

Stirring guarantee is possible

Use of solid manure and grass silage in ÖKOBIT plants is fully unproblematic


Agitator Digester – low speed



Agitator Digester – fast running



Double-Membrane Roof System


Storage for gas Function of a lung Shape resistant to wind, rain and

snow Level of gas bubble measured by a

belt system with sensors Intelligent connection of the gas

storage with the CHP plant CHP power can controlled by

bubble level (e.g. for demand-oriented peak current)

Mounted on top of the wall with stainless steel clamping rails


Double-Membrane Roof System



Solid Feeding System


Feeding unit for solids, e.g. solid manure

Storage volume: 7 m³ HDPE extruder welded mounted floating in steel frame No corrosion and no wear in the

storage area Stainless steel screws for bulking

the solids with chain drive Stainless steel screw conveyors to

feed substrates into digester

Concept and requirements FermPipe


• Digester as tube, PE pipe, double layer, 100 m³ volume• smaller pipe with high speed agitator, meander as principle for agitating• Integrated heating system in outer wall• Inner wall works as heat exchanger• Entrance over gas dome possible• Low civil engineering costs and space requirements• Thermophile temperature (max. 55 degrees celcius)• Only in combination with insulated and gas-tight storage tank• Total possible input: 4,000 m³/a
