Wood burner. The Veto Spring Agitator burner (biomass burner for solid fuel) with a container has been designed to solve to the challenges of contemporary burner equipment. The 16 m³ silo enables a large load of fuel to be added to the container during a single loading. The sturdy spring-loaded structure enables to use various types of solid fuel (wood chips, peat, pellets, cutters, sawdust and other small-diameter fuels). The circular feed pipe (the semi-circular feed pipe with the capacity of 40 – 120 kW) ensures that the fuel is fed into the burner evenly. The silo's air-tight lid, the BVTS valve, the wax plug, and the programmed rear flame retardant ensure that it is safe to use this stoker. The control panel is the A-T Log 1, with cutting-edge technology, which makes the device easier to use. The silo's filling direction can be adjusted in four different ways. The Veto Spring Agitator with a container is available with a 40 – 640 kW burner. The feed screw size Ø 125 – 200 mm (depending on the capacity of the burner).
