The Veto 6 is a modern wood chip burner (biomass burner), with two sturdy spring-loaded mixing trays for unloading fuel. These sturdy mixing trays enable to use various types of solid fuel in this stoker (wood chips, peat, pellets, briquette). The basic size of the silo is 2 m³, and extension silos are available for that as an accessory, in the following sizes: 0.5 m³, 2 m³, and 4 m³. The Veto 6 wood chip burner (biomas burner) can be installed into Veto stoker boilers. The silo's air-tight lid, the AVT-A valve, the wax plug, and the programmed rear flame retardant ensure that it is safe to use this stoker.
