The conveyor is designed for dosed fuel supply (wood, peat, or agropellets) with a maximum diameter of 10 mm from the hopper to the boiler burner. The conveyor workflow is controlled by the boiler or burner controller according to the set work program. The segmental design of the auger conveyor with turns of large radii and straight sections, allows to provide a connection between the boiler and the fuel warehouse, located in buildings with a layout that is inconvenient to ensure the fuel supply process.
