In this paper the solutions, types and groups of immovable mixers for the dedicated biogas power plants, as well as the connections (calculation) of the pipes for the transport of the substrata from the mixer to the digester are presented.
The continuous feeding on biogas devices represents the challenge with which every producer of the electricity, more precisely, of the biogas device, is faced.
Apart from numerous research, the feeding with the immovable mixers for the dosing of the mass, turned out to be an adequate and the most economical solution.
The using of the immovable mixers with the direct inserting of the mass into the digester represents the most effective way of feeding the biogas devices which have the need for the solid matter and it does not have the liquid preparation. The new way of feeding is ideal for the biogas devices which have diagonal mixers in the digesters and which can follow the dosing of the immovable mixers.
