Hasselager, Denmark
- Installation
Waste-fired factory with increased emission and environmental requirements. - Fuel
Mixture of seed and grain as well as feedstuff residue, dust, chaff, whole grain and pressed grain. - Boiler
Danstoker Multimiser No. 19, which is a 5-pass hot-water boiler with a 2 MW output. The boiler was installed in 2001.
The problematic fuel meant that the boiler needed to be cleaned manually for every 14 days of operation because of heavy deposits in the tube passes. The decision was consequently made to retrofit the AEROVIT system in December 2002.
Without Aerovit
26 Manual cleaning per year.
Manual cleaning, 8 hours every 14 days. Downtime: 24 hours for each boiler cleaning.
