Special challenges
Measurement through narrow chute, poorly reflecting medium, measurement during filling
Application
Waste incineration converts domestic and commercial waste into combustible gases and ash. Pyrolysis is carried out in the absence of air at temperatures up to 500 °C. The intermediate product, charcoal, is then further burned by adding air. Ash and synthesis gas with high thermal content are the end products. For continuous operation, the vessel must be loaded and emptied automatically. To this end, the level of material in the pyrolysis chamber and in the ash pan has to be measured.

VEGAPULS 69
The ideal solution for this application is the radar sensor VEGAPULS 69. With its small beam angle, the instrument measures with extreme precision through the narrow chute down to the ash container. Thanks to the high dynamic range of its measuring method, it gathers level data reliably in spite of the poor reflectivity of the ash. The non-contact measuring method also makes the instrument virtually maintenance free. VEGAPULS 69 prevents backup and ensures that the ash container is always emptied at the right time, guaranteeing reliable, continuous operation of the plant.
