Feeding of the reactors becomes one of the most important part in managing a Biogas plant, because it is a critical factor for the stable biogas production.

This article overviews all the experiences we could gain from a research work performed in a biogas plant, aiming the improvement of the applied technology, focusing on the solid input material crushing process.

The intensive abrasion causes serious problem in the hammer crusher, and because of this, breakdowns, operational failure, and economic damage can appear in the biogas plants quite often. Hammers wore rapidly causing inappropriate chopping. If the crushing is not effective, the fibrous material reduces the mixing efficiency that causes less gas production.

Within the frame of the research, we worked out the applicable technology for improving the abrasion resistance of the hummers of the crusher that caused improved reliability for not only the equipment, but the whole biogas plant as well.

Key words

renewable energy production, biogas technology, circular economy, adequate repairing technology, plant management
