The system has a conveying unit (13) arranged in a conveying channel (19) and is driven directly or indirectly by an internal combustion engine (2) e.g. diesel engine. A primary heating device (P) is provided for the conveying unit and/or the conveying system. A secondary heating device (S) partially reduces load of the primary heating device by using direct or indirect unused waste heat of the combustion engine. An engine exhaust air collecting system (10) and an engine exhaust air guiding system (18) are guided from the engine in an area of the conveying unit. |
