Inspection chamber to control the biogas in the already restored area Biogas conditions detail Biogas piping pass key detail Gas circulators of the aspiration centre

The network of pipes, which is buried in trenches in the already restored areas, and aereal in the closed and operational areas, makes it possible to transport the biogas captured from the wells. It has utility shafts, sectoring valves, and a set of purging devices that allow excessive humidity (condensate) to be removed from the captured gas. The biogas is aspirated from the wells by means of a system of tubes and pipes with different diameters, which finally meet in two main collectors, with diameters of 355 mm, which, in turn, lead it to the aspiration centre. The whole biogas capturing and transport system is kept at a pressure below that of the atmosphere, thus ensuring that no biogas can escape to the outside. The system is fitted with three centrifugal gas circulators, each with a capacity of 3,000 m3/h. It is at this point that the depression is created, required for the gas to circulate in the entire network and receive the required impulse towards the engine generators or, when required, towards the high-temperature safety torches.
