USF-S
Underfeed combustion 100 - 300 kW
The compact ENDRESS USF-S wood combustion system guarantees economic and efficient residual wood utilisation even for small output ranges from 100 to 300 kW.
Suitable for dry fuels such as wood chips, wood briquettes, pellets, sawdust, sanding dust and shavings - especially also for fuels of classes 6 and 7.
Ingenious design
2-sided ventilated combustion chamber
High efficiency: Clean combustion by virtue of 2-sided, controlled ventilation of the cantilever combustion chamber made of high-temperature ceramic cement. The 15 mm thick steel fire retort has an automatic ash discharge and standard ash containers for convenient disposal. Robust boiler with 10 mm boiler wall thickness.
High temperature resistant grate bars
Long service life: Grate bars of the underfeed retort are made of high-temperature resistant cast stainless steel with 27 % chrome content.
Automatic cleaning
High comfort: The permanent removal of ash deposits from the heat exchanger and combustion trough ensures a consistently high boiler efficiency, prolongs the cleaning intervals and saves time as well as cleaning material.
Automatic ignition
Comfortable heating: A sophisticated ignition programme, in conjunction with the temperature-controlled ignition fan, ensures simple, material-saving heating.
Standing tube heat exchanger
High thermal performance: Large-volume, high-performance heat exchanger in 3-pass design
High quality drives
Made in Germany: The stoker screw and ash discharge are driven by high-quality geared motors.
