14. Demonstration model - condensing boiler technology

During the project ZEBA has developed a demonstration model for condensing boiler technology (see graphic below). The demonstration model can be used in practice-oriented initial and continuing vocational training. With it students can easier understand the function of condensing boiler systems. Also, frequently occurring errors can be simulated and test measurements be performed. On the following pages the model and its function will be briefly presented.
