Technical specification of the circuit of four cogeneration units
The source of electrical and thermal energy consists of four cogeneration units: a pair of two identical engine-generators powered by biofuels (the device is also adapted to be powered by natural gas – GZ-50 or LNG) and a pair of two identical engine-generators powered by methan-rich natural gas GZ-50 or LNG.
The technology used in the process of generating electric and thermal energy is an internal multi-cylinder combustion engine (four-cycle). The engine-generator is compact; the engine and the generator are joined and elastically fixed to the frame. Thanks to this solution the already minor vibrations are isolated from the frame. The remaining vibrations are eliminated through placing the engine-generator on an isolation pad (e.g. sylomer). The engine shaft is directly coupled with the shaft of the synchronous generator with the number of pairs of magnetic poles p=2 (for gas-engines) and the number of pairs of magnetic poles p=4 (for the engines powered by biofuels), hence the rotational speed of gas-engines is 1500 rpm (high-speed engine) and for engines powered by biofuels it is 750 rpm (low-speed engine). The generator is intended to work in parallel with the electro-energetic network and it is adapted to work for an allocated, autonomous electro-energetic system.
Le generateur est destine a travailler simultanement avec le reseau de production electrique mais est egalement apte a travailler en tant que systeme de production electrique autonome a part entiere (en toute autonomie)
The solutions to protect the environment
The installation is efficiently isolated from the environment thanks to the sound-absorbing walls. This strategy protects the environment from the noise emissions but also, in the unlikely situation of oil spill, keeps the ground and water environment from contamination.
Thanks to the up-to-date technology and the machines characterized by low energy consumption, the efficiency of electrical and thermal energy generating achieves c. 82%.
As the water is isolated within the cooling system, the installation does not produce sewage. The waste water from the industrial premises are, if necessary, purified from any suspended solids or petroleum derivatives.
Protection from the vibrations is ensured by the up-to-date construction of the machines (e.g. the interconnection of the engine and the generator), their perfect alignment and the use of isolation pads.
