WtE plant Wien Spittelau
The waste incineration plant Spittelau, in Vienna, was built and put into operation between 1969 and 1971. It became famous later on, due to its colourful façade designed specially by the artist Friedensreich Hundertwasser. Many years ago, Mokesys® tiles had already been tested and used in both of the old boiler lines. Due to experience gained and the planned energy and economical optimisation of the entire plant, Wien Energie, as plant operator, decided to go again with the proven Mokesa quality on the occasion of the new lining of boiler line 1 in 2014. In addition, the concrete and refractory mass surfaces inside the boiler were minimised in order to ensure flawless operation for as long as possible. In doing so, improved solutions were found for the sensitive areas around the ignition and burnout noses and the connections to the moving hearth. Apart from standard tiles, the proven Mokesys® radius tiles were used as well. After completing the initial installation of boiler line 1 with Mokesys® refractory tiles, it was successfully put into operation in March of 2015. The service life of the entire refractory lining was significantly increased by means of these measures implemented. Every year, 250,000 tons of waste are recycled at the EfW plant in Wien Spittelau and from this, heat for 60,000 households and power for 50,000 households generated. District heating therefore makes a significant contribution to the reduction of greenhouse gases and air pollutants in the Austrian capital and avoids 1.5 million tons of CO2 effluent every year.
