1
Minimum load:
Operation with modulated control (Infinitely variable power control)
Low load with ON Qmin / OFF (Stop-and-go mode)
2
Moist fuels:
Efficiency: Specification with displacement rods and flue gas recirculation system
or dry fuels (W5 to W20) without flue gas recirculation system-reduced values
3
Wet fuels:
>W35 further limitations regarding output, degree of efficiency and control behavior
4
Specification:
See Section Wood Fuel Requirements
5
Flue gas temperature:
An increase is possible by removing the displacement rods [Full load 86° F (30° C);
Partial load 50° F (10° C)]
6
Pressure:
Per ASME Sec. IV
7
Overall weight:
Includes displacement rods
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 flue gas temperature by approx. 59° F (15° C).
