Minimum load:

Operation with modulated control (Infinitely variable power control)

Low load with ON Qmin / OFF (Stop-and-go mode)

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

Wet fuels:

>W35 further limitations regarding output, degree of efficiency and control behavior

Specification:

See Section Wood Fuel Requirements

Flue gas temperature: An increase is possible by removing the displacement rods [Full load 86°F (30°C);

Partial load 50°F (10°C)]

Pressure:

Per ASME Sec. IV

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).
