In 2016, the Dutch company KARA Energy Systems implemented a system for the visualization and control of district heating in Ede.
Two boiler plants produce steam used in two turbines for power generation. Residual steam is converted in a condenser into condensate (water) that is pumped back into the boiler via a circuit. This condensation is done by pumping cold water from the city through the condenser. This includes a heat exchanger to keep both circuits separated. The cold water is heated by the steam and then again pumped to the city as hot water.
The boiler plants are fed with wood chips supplied by trucks. On delivery, this wood is thrown into a dump pit. Using a crane, the wood is then transported either to the storage bunker or to the hoppers. From the hoppers, the wood is transported by a worm conveyor and a scraper conveyor to the furnace.
To monitor and control the processes of power generation and heat supply, the Reliance SCADA/HMI system and five Hitachi PLCs are used.
