  • Biogenic Refinery
    Publication number: 20240083774
    Abstract: A biogenic refinery has a pyrolysis pot, an exhaust plenum, and a drag chain conveyor system having first and second drag chain conveyor portions. The first and second drag chain conveyor portions have a drying region disposed in the exhaust plenum with the second drag chain conveyor portion depositing feedstock in the pyrolysis pot. A control system includes a drive to control the drag chain conveyor system, a humidity sensor sensing moisture in the exhaust plenum, and a controller that receives a signal from the humidity sensor, compares the humidity sensor signal with the desired moisture level in the exhaust, and controls the drag chain conveyor system based upon a difference between the humidity sensor signal and the desired moisture level in the exhaust to control a rate of movement of the feedstock through the drying regions of the first and second drag chain conveyor portions.
