Advances in gasification for sythesis gas production
Design and Validation of Auger Jam Recovery Algorithm for a Novel Plug-flow Biomass Conversion System
Short Introductive summary
This technical paper is on the automated recovery of an auger jam from the plug-flow form of biomass conversion called Indirectly-Heated Pyrolitic Gasification (I-HPG), which is the subject of five patents in the United States. A detection algorithm is implemented in Simulink, where the jam signal is input using a manual switch. The algorithm is designed to detect up to four levels of jam severity. If the system identifies a jam for the first time, the auger is operated in reverse direction for three (3) seconds, and then returned to the normal forward-moving direction . Repeated jam occurrences trigger longer reverse operation durations (five seconds for the second jam and twenty seconds for the third jam) to attempt reversal of the auger motor. If the jam cannot be cleared after such, an error is flagged, and the system is shut down for maintenance. The model is tested and validated with different error cases.
