    • The object of the invention is a biogas generator with tunnel fermentation chamber, equipped with biomass container with thermally insulated base and essentially vertical foundation walls, installations for moisturising biomass with a process liquid, installations for recirculation of seepage water, arch roof covering spread over arch load-bearing construction and supported on essentially vertical foundation walls, gas-tight gable walls, and biogas store created by double layer of roof covering foil with inlet to biogas store situated in upper part of fermentation chamber, characterised in that two layers of foil, upper (3a) and lower (3b), forming biogas store (3c), are secured on opposite sides of rigid arch roof covering load bearing construction, the lower foil (3b) has, at approx. 1/4 of the height of arch load-bearing construction, gas slots (29), duct fan and a duct fan (8) forcing circulation of biogas to biogas store (3c) is connected into the inlet channel, wherein lower edges (5) of roof covering are supported on upper part of essentially vertical foundation walls (1) of the biomass container, while the installations for moisturising biomass with process liquid have moisturising nozzles (7a), placed in the biomass loading zone and variable heights, depending on the height of the biomass loading zone, preferably in intermediate zone (1b), and furthermore in the biomass loading zone there is a channel (2) for pulp, preferably created by a perforated barrier (4) supported on the base of biomass container or constituting a perforated pipe, suspended, supported or resting freely in a biomass layer.
      The invention also includes installation to produce and utilise biogas, comprising a tunnel fermentation chamber, constituting a space inside a biogas generator with a convex roof covering spread over an arch load-bearing structure, a gas store formed by two layers of roof covering foil with an inlet to the gas store situated in the upper part of the fermentation chamber, installations for moisturising biomass with a process liquid, installations for recirculation of seepage water, a cogeneration system powered by biogas supplied through a gas pipeline from the biogas store and an automated system for controlling the process of production and utilisation of biogas, characterised in that two layers of foil, upper (3a) and lower (3b), forming the biogas store (3c), are secured on opposite sides of the rigid arch roof covering load-bearing construction, the lower foil (3b) has gas slots (29) at approx. 1/4 of the height of the arch load-bearing construction, and a duct fan (8) forcing circulation of biogas to biogas store (3c) is connected into the inlet channel, wherein lower edges (5) of roof covering are supported on upper part of essentially vertical foundation walls (1) of the biomass container, while the installations for moisturising biomass with process liquid have moisturising nozzles (7a), placed in the biomass loading zone and variable heights, depending on the height of the biomass loading zone, preferably in intermediate zone (1b), and furthermore in the biomass loading zone there is a channel (2) for pulp, preferably created by a perforated barrier (4) supported on the base of biomass container or constituting a perforated pipe, suspended, supported or resting freely in a biomass layer, supplied with pulp through an internal pipeline (6) situated in the channel (2) for pulp, wherein the installations for recirculation of seepage water include a non-membrane heat and mass exchanger connected with through a seepage water pipeline (20) with the biomass container and a return pipeline (22) with installations for moisturising biomass with a process liquid, and wherein the non-diaphragm heat and mass exchanger has a permanent mass (15) of a high heat capacity, through which seepage water is passed in the opposite direction to exhaust gases supplied to the permanent mass by an exhaust conduit (19) from the cogeneration system.
