The subject of the entire investment is the housing of two electric power generators in a designed technological building. The building consists of the following rooms:
- two independent engine halls, separated with a wall
- pump station with exchange station
- switchgear 0.4 kV
- switchgear 15 kV
- two rooms with unit transformers
- auxiliary transformer rooms
Cogeneration generators will be located in soundproof rooms.
The engines will be powered by GZ-50 natural gas.
The generator unit will include:
- heat recovery system from cooling water: engine housing, oil system and flue gas cooling
- interstage cooling system of fuel mixture
- emergency engine cooling system with the water/air cooler
- fuel-air mixture cooling system after the 2nd stage (lost heat)
- lubrication system
- flue gas removal system
- gas line
- vantilation and combustion air system
- gas detection system,
- fire risk detection system
