1
Minimum load:
Operation with modulated control (Infinitely variable power control)
Low load with ON Qmin / OFF (Stop-and-go mode)
2
Moist fuels
:
>W35 further limitations regarding output, degree of efficiency and control behavior
3
Specification:
See section on Wood Fuel Requirements
4
Flue gas temperature:
An increase is possible by removing the displacement rods [Full load 86° F (30° C);
Partial load 50° F (10° C)]
5
Pressure:
Per ASME Sec. IV
6
Weight:
Includes door and refractory concrete lining
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. 68° F (20° C)]
