Abstract: The invention relates to a biomass power plant for dry-wet simultaneous fermentation, having dry fermenter modules comprising dry fermenters. In order to refine the biomass power plant such that the length of the pipes for delivering process water is reduced to a minimum, the invention proposes to integrate a process water reservoir between two dry fermenter modules.

Abstract: An apparatus for the opening up of garbage dumping ground gas sources and for the exploration and sanitization of old deposit site burdens and contaminated soils. A hollow cylindrical probe is insertable into the gassy zone of the dump and is provided with wall perforations, serving as gas inlet apertures, as well as with a gas evacuation duct. The apparatus posseses a rigid probe body permitting it to be pile-driven into the dump or soil surface. The body includes a hollow cylindrical steel container, the casing wall of which is provided with the wall perforations and the diameter of which is larger than that of a gas evacuation duct coaxially and detachably connected therewith the apparatus is insertable with as little disturbance as possible of the dump material. At the same time, the apparatus forms a cavity therein which is suitable as a gas collection and control chamber.
