Biogas e.g. methane, production method involves guiding supplied solids on horizontal delivery path below fermenting pile, where percolated liquid and/or small fraction of pile down drips or falls on solids to be fermented

摘要

Biogas production involves mixing and heating supplied solids to be fermented at a preliminary stage. The heated solids are distributed from the stage on a fermenting pile provided in a fermenter. The solids are distributed on a lower surface of the pile. The supplied solids are guided on a horizontal delivery path below the pile, where percolated liquid and/or small fraction of the pile down drops or falls on the solids to be fermented. An independent claim is also included for an arrangement for biogas production by dry fermentation.
