摘要

Fuel dosing device, especially for dosing secondary fuels, comprises a cellular wheel sluice (6) having a material inlet (8) above the cellular wheel and a material outlet provided by a fan (5) arranged in front of the cellular wheel sluice and connected via a pneumatic main conveying line (4) to a combustion furnace. A secondary conveying line (1) provided in the region of the material inlet for dedusting and connected to an intake device opens into the main conveying line. Preferred Features: A transport ventilator (2) provided as the intake device feeds the dust, easily extracted constituents and leakage air via the secondary conveying line in the region of a burner (3) of the combustion furnace into the main conveying line. The cellular wheel sluice is a blow-through cellular wheel sluice having chambers from which the secondary fuel is blown into the main conveying line.
