Erdgas Schwaben supplies the city of Dillingen with environmentally friendly and cost-effective bio-heat from a biomass ORC cogeneration plant. eta Energieberatung develops measures for the technical and operational optimisation of the biomass CHP plant with district heating network in Dillingen.
Through eta Energieberatung a sustainable concept for a secure procurement of fuel assortments was developed and a regional market overview was created. In addition, a profitability analysis and a sustainability assessment was carried out.
The new concept envisages using a heat pump to raise the temperature level of the low-temperature waste heat generated in the condensation power plant. The waste heat can then be integrated into the production process in combination with a CHP plant and a pre-dryer. This results in annual energy cost savings of approx. 1 million €.
By implementing an innovative steam generation system using CHP, consisting of a conventional steam boiler with micro gas turbine and gas turbine exhaust gas burner, renewal of the steam distribution system with a pure steam generator and a new ventilation system to supply highly hygienic areas, CO2 emissions were reduced by almost 20 %.
In Taufkirchen (Vils), a district heating network with a route length of approx. 5,200 m and 41 heat transfer stations was built. The base load requirement is covered all year round by combined heat and power plants. In addition, a community-owned conventional peak and reserve system was also set up.
The waste heat of a local foundry was integrated into the existing heating network. The existing district heating network was extended to connect a school centre. In the course of this, extensive conversion and expansion measures were carried out on the existing hydraulic and control technology and a buffer storage tank was installed.
eta Energieberatung provided a rough analysis for the evaluation of measures to reduce energy costs. The areas of waste heat utilisation, cooling water, electric drives and fans, lighting optimisation, own power generation, renewable energies and support measures were included.
In Engelsberg, a biomass heating plant with a capacity of 1,700 kW and a district heating network with a route length of approx. 7,400 m and 180 heat transfer stations were built. Afterwards, the biomass heating plant and the district heating network were optimised during operation.
At Lauterbach castle, which has been owned by the von Hundt family since the 15th century, the oil heating system was replaced by a woodchip heating system. A neighbouring house is also supplied with heat by this system. eta Energieberatung was commissioned with the planning of the wood chip heating with connected local heating network.
The main focus of product development is to examine what charging capacity is required when building a new e-bus charging station and what measures can be taken to optimise the investment and running costs.
Various charging concepts for electric vehicles were analysed for SWM. In addition to the technical specifications for the installation of charging points, the connection of the charging points as well as the specifications for the recording of measured values were examined.
The community Wunsiedel will become a pellet stronghold through the investment of 30 million euros in the new pellet plant with a connected CHP. The new pellet plant is supplied with the necessary energy by three connected natural gas CHPs.
It was analyzed how the location can be supplied with energy in a CO2-neutral manner. For efficient energy generation and optimal use of fuel with biogas cogeneration units, the heat supply had to be split into a separate high and low temperature supply.
After successful cooperation with the wood pellet plant, the Stadtwerke Wunsiedel also relied on the technical support of eta Energieberatung for this local heating concept with a wood gas cogeneration unit and pellet boilers.
Daimler AG is building a new engine plant in Jawor (Poland). The energy supply should be CO2 neutral via external suppliers. Eta Energieberatung was involved in the concept creation and implementation for the CO2-neutral heat supply as well as a transitional supply to the engine plant.
