Success Story Renergia Zentralschweiz AG
Boosting power, cutting emissions, driving profitability
Imagine a waste incineration plant in the immediate vicinity of a residential area that increases its capacity without triggering a wave of indignation and objections - and, by the way, can also reduce operating costs. This is exactly what Renergia near Lucerne (Switzerland) has achieved thanks to its close cooperation with Rocket Science.
The company
Renergia Zentralschweiz AG operates one of Switzerland's largest waste incineration plants, which recovers the waste heat. The location at the interface between a residential and an industrial area is strategically advantageous. It allows both the efficient collection of waste from the entire central Switzerland and the effective distribution of the produced energy (heat, steam, electricity).
The challenge
Due to the increased demand for incineration capacity and thanks to the available technical possibilities, Renergia has planned to increase its capacity. This resulted in noise emissions - due to the inherent complexity of the system - which had an impact on the profitability of the plant. The more energy the system produces, the more noticeable is a ship's horn-like resonance phenomenon, which increases to a high volume at peak load. As a result, the plant could not be operated at full load or only at certain times.
The solution
Rocket Science successfully tackled the resonances with an Active Noise Cancelling (ANC) system. The plant can now be operated at full load at any time without increasing emissions. However, Rocket Science's solution has two further advantages:
- The overall efficiency of the plant is not reduced - unlike passive resonators / silencers. This also has a positive effect on the profitability of the plant.
- The system can be installed during operation. The plant did not have to be shut down.
