NOVELTY - The biomass power plant comprises dry fermenter modules (11, 12) comprising four dry fermenters (19, 20), a process water reservoir (10) integrated between the dry fermenter modules, process water lines formed between the process water reservoir and the dry fermenter modules, and a process water collection duct (15) that is coupled in the form of a module with the process water reservoir and/or the dry fermenters. The dry fermenters have perforated grating segments made of stainless steel and/or plastic installed on the side.    USE - Biomass power plant useful for dry-wet simultaneous fermentation for the production of biogas.    ADVANTAGE - The biomass power plant is compact and can be simply and economically constructed.    DETAILED DESCRIPTION - The biomass power plant comprises dry fermenter modules (11, 12) comprising four dry fermenters (19, 20), a process water reservoir (10) integrated between the dry fermenter modules, process water lines formed between the process water reservoir and the dry fermenter modules, and a process water collection duct (15) that is coupled in the form of a module with the process water reservoir and/or the dry fermenters. The dry fermenters have perforated grating segments made of stainless steel and/or plastic installed on the side and have a light width of maximum 4.5 m and a light height of maximum 5.0 m. The perforated grating segments are inclined to 2 degrees in such a way that its interval increases towards the top to the side wall of the dry fermenters. The dry fermenters are equipped with concentric nozzles integrated into the dry fermenter cover. The process water collection duct has a volume of 50 m3 and is arranged against one of the side of the process water storage turned to the dry fermenter. Piping, pumps, blower and booster are arranged above the dry fermenter cover by machine technology. A gas storage and/or biofilter are arranged on the side of the dry fermenter modules turned to the process water reservoir.
