Continuous output: Output levelling out as base load boiler in continuous operation with pneumatic cleaning
system (for track time, see Operating Instructions)
2)

3)
Efficiency: Specification with displacement rods and flue gas recirculation system
for dry fuels (W5 to W20) without flue gas recirculation system-reduced values
4)
Wet fuels: >W45 further restrictions in terms of output, efficiency and control behaviour
5)
Specification: See Spec Sheet 1010, Minimum Requirements for Wooden Fuels
6)
Exhaust gas temperature: A reduction is possible by installing the displacement rods (Q
N
- 20°C; Q
min
– 10°C)
Other influences: fuel water content, ash content, pneumatic cleaning system yes/no, track time (number of
operating hours without cleaning) Specifications for the start of the track time (toward the
end of the track time there is an increase in the exhaust gas temperature by approx.
+15°C)
