Modernization & heat pump integration in the Saalfelden heating plant
THERMA FLEX DEMO PROJECT: Increased efficiency of the existing biomass boiler
In order to increase the share of renewable energy in the Saalfelden district heating network, work is currently underway on a comprehensive modernization of the Saalfelden heating plant. The modernization is planned in two stages. The essential components of expansion stage 1 to increase the efficiency of the existing biomass boiler are:
- Adaptations to the existing biomass firing system, including increased performance of flue gas condensation and improved exhaust gas cleaning
- Construction of a storage tank (150 m³)
- Renewal of the control technology / control
- Renewal of the thermal hydraulics
In expansion stage 2, the energy efficiency of the system is to be further increased through the implementation of an innovative heat pump concept. By using a heat pump, the heat recovery from the flue gas can be significantly increased again.
In parallel to the two stages of modernization, work is being carried out on optimizing and expanding the district heating network.
