Bibliography

These requirements apply to atmosperic fluidized-bed and grate firing systems. This system commence at the fuel bunkers and at the ash extractions plant. For combination of various firing systems, the individual requirements of each system shall also apply, especially those included in prEN 12952-8 and prEN 12952-9. If several fuels are burnt simultaneously or if a fuel quality varies considerably (e.g. moisture content), additional safety measures may be necessary, especially with respect to limitation of the fuel flow into the firing system and ensuring proper air supply to the individual fuels.
