In the modern KVA Linth plant, waste is not simply incinerated, but is used to generate thermal energy for electricity and district heating. KVA Linth also separates iron scrap from incineration residues. With the realization of far-reaching renovations, the consortium (arising from the merger of 28 local municipalities) has made a clear commitment to environmental protection. The ecological impact has been reduced to an absolute minimum.
The Linth waste incineration plant uses the waste heat from waste recycling to supply customers with ecological district heating. A district heating network functions like a large central heating system. Instead of generating heat in each individual building, the Lint waste incineration plant supplies an entire region.
The commando room is the switching centre of the Linth waste incineration plant. The entire plant is controlled and monitored from here around the clock, 365 days a year. The crane that feeds the incinerator with refuse is also operated from here. The commando room was completely renovated in 2016, including the deployment of a new process control system that makes it easier to evaluate and process data. A static circuit diagram made way for a modern dynamic video wall, the workplaces were redesigned for ergonomics and the technical furniture was replaced.
The static so-called "mosaic" mimic diagram was replaced by a dynamic video wall consisting of 10x 60" modern rear projection cubes. The video wall offers full flexibility with regard to the switching and display of sources. It displays not only the new 800xA distributed control system from ABB, but also CCTV video images of the incinerator itself, office information, alarms, etc.
The generous video wall is the eye-catcher in the new control room. It is also used for educational purposes and for public relations, e.g. during public tours of the facilities.
With WEYTEC smartCONTROL, every image on the video wall is freely selectable, placeable and scalable. The dispatchers can use shortcuts on the tailor-made keypads of the smartTOUCH keyboards to select between different video wall presets. This makes it much more intuitive and faster than ever before to use the new process control system.
The Project with ABB
When KVA Linth decided to renew their control system, they opted to completely redesign the commando room. ABB was the general contractor and after conducting their own research, ABB chose the WEYTEC solution as the smart addition to the overall package. The WEYTECdistributionPLATFORM makes it possible to display all information sources on any screens, including the video wall, and to operate the entire working environment via a single multifunctional keyboard.
