Mammern heating network, Mammern TG, Switzerland
Regional forestry timber – heat for Mammern
The district heating network in Mammern is operated by the Wärmeverbund Mammern cooperative. Fernheizzentrale Mammern GmbH supplies the thermal energy from regional forestry wood.
The Mammern district heating plant has been reliably supplying heat to the district heating network since December 4, 2023
In September 2023, two Schmid wood firing systems, two electrostatic precipitator and a heat storage tank were installed in the Mammern district heating center. After installation, the two moving grate firing systems were gradually transferred to regular operation, technically adjusted and optimized for maximum efficiency.
The central heating system has been reliably supplying heat to the Mammern heating network since December 4, 2023. Thanks to the modern technology, the system can be further optimized as required via Telemaintenance so that the system is set efficiently even under changing conditions.
Wide range of fuel – Schmid firing system an “all-rounder”
Fernheizzentrale Mammern GmbH obtains the required fuel from the regional forestry companies. In order to ensure that all parties involved can plan ahead, the fuel deliveries were set out in an agreement.
For the Mammern district heating center, this means that the availability of fuel from the region is guaranteed, but the quality and fuel moisture levels fluctuate. Changing fuel qualities and moisture levels are an important criterion when choosing the right combustion system.
The feed grate firing systems from Schmid are designed precisely for these conditions. Thanks to the special design of the grate and the sophisticated technology, high efficiency levels with the lowest emissions are possible with these firing systems.
It is incredible how efficiently the firing system works. Whether freshly cut maintenance wood or well-stored wood, the combustion technology from Schmid regulates combustion perfectly.
