Summary
Spittelau waste incineration plant in Vienna processes approximately 1,000 tons of waste daily, generating energy for around 10,000 households. This facility plays a crucial role in the local energy supply by converting waste into usable heat and electricity.
Waste is manually mixed to ensure a consistent calorific value before incineration, which occurs at temperatures between 850 and 1,000 degrees Celsius. This process produces steam that drives a turbine for electricity generation.
Heat generated from the incineration is transferred to a district heating network, with a significant portion directed to the Vienna General Hospital (AKH). The hospital's energy demand is comparable to that of a city like Wiener Neustadt.
A dual pipeline system allows for heating during winter months, while one line can be switched to cooling mode in summer, providing climate control for the hospital. This system enhances the efficiency of energy use throughout the year.
