Efficiency + ensures program by WELTEC optimal concept k angle agricultural KG has connected to a district heating network on the basis of bio-gas the first residential building late September in Tauhardt (Saxony-Anhalt). This could be an example because after the verebbten boom in building of biogas in Germany the bio gas investment portfolio to optimize is. The first were connected to the district heating network of a total of 51 houses. The heat provides a so-called satellite block heat and power (CHP) that could install the k angle agricultural KG by WELTEC BIOGAS POWER GmbH about their program efficiency +. Specifically, a branch line was laid by 2.7 km in length by an existing biogas plant to the new satellite-CHP. Over the line, biogas comes out of the plant, which stands in Saubach, according to Tauhardt. There, dug the biogas in the satellite-CHP and waste heat from the electricity used for a chicken fattening and in a district heating network. So far, the biogas plant in Saubach drove only on about two-thirds of the potential power of gas.
The limitie-rende factor was the lack of sales of falling to heat when the electricity generation from biogas. Now, the biogas plant in Saubach can extend their load fully in cooperation with the satellite plants in Tauhardt. Two locations: The original in Saubach with a power of 600 kilowatts electrical and new, who has an electrical output of 365 kW. The project was designed and implemented by the bio gas plant manufacturer WELTEC BIOGAS POWER GmbH, Vechta on its optimization program for biogas plants, efficiency +. In the program are biogas plants analyzed individual improvement concepts developed and implemented, which differ from the general concept of repowering for biogas: dealing with individual modules which optimize a system running according to financial and approval situation. The measures range from the technical and biological process optimization about heat utilisation possibilities plant expansions. Tauhardt installed on a heat buffer tank with a volume of 3,000 cubic meters. He ensures the contractually guaranteed thermal performance in the District heating network with. The investment in the district heating network to amortize Brown and Hans Herrmann Klug according to Kahlwinkel – agriculture – managing director Roland in ten years. The efficient biogas is gaining economically for biogas plants in the future, because the renewable energy sources Act (EEG) while over 20 years guarantees a remuneration, in it but not the price increases in the market for substrates and the management are taken into account.
