A biogas plant fermenter supply method increases total throughput of substrate through fermenter chambers while not changing the number of fermenter chambers. An inoculum fermenter chamber is supplied with raw fermentation substrate and fermenting for a dwell time, returning part of the substrate fermented in the inoculum fermenter chamber in the form of a self-inoculating substrate to the inoculum fermenter chamber by a return path, the part being mixed with the raw fermentation substrate, and supplying a fast fermenter chamber coupled to the inoculum fermenter chamber with an additional part of the substrate fermented in the inoculum fermenter chamber in the form of a fast fermenter inoculation substrate and mixing the additional part with fast fermenter raw substrate of an amount per unit of time, wherein fermented output substrate is removed from the fast fermenter chamber after a dwell time of the substrate mixture introduced into the fast fermenter chamber.

Abrégé

A slag remover for discharging combustion residues of an incineration plant comprises a trough, which has a trough housing having two side walls, which define the trough width, and having a trough bottom, and which is intended to collect the combustion residues evacuated from a combustion chamber of the incineration plant. The trough further comprises at least two push rams for pushing the combustion residues out of the trough, and a shaft rotatably mounted in two shaft bearings and on which at least one drive lever cooperating with a cylinder-piston unit and at least two output levers connected to respectively one of the push rams are disposed in a rotationally secure manner. The cylinder-piston unit is here designed such that the push rams move back and forth between a retracted position and an extended position. The drive lever is disposed between two output levers.

A plug-flow operated, horizontal fermenter for anaerobic fermentation of biogenic waste includes a fermenter tank having an inlet and an outlet that is configured to be filled with a biomass material. The fermenter also includes an agitator having a shaft passing through the fermenter tank in its longitudinal direction, wherein the shaft is mounted in end regions of the fermenter tank and is designed as a closed, hollow shaft having an inner space filled with gas or air. A plurality of agitator arms are arranged on the shaft. The inner space of the shaft is monitored with respect to a gas or air pressure to ensure that a buoyancy of the shaft in the filled fermenter tank at least approximately compensates for a sagging of the shaft.
