Solar receiver installation with pressurized heat transfer fluid system

A solar receiver installation with a pressurized heat tranfer fluid system equipped with a pressure relief valve (2) and a trapping device (10) for separating liquid droplets from a pressurized gas released by the pressure relief valve (2) and for capturing said liquid droplets, said trapping system comprising, in use, a vertical exhaust pipe (3) connected to the horizontal pipe (4) substantially in a perpendicular manner and having an open end for discharging in the atmosphere the gas released by the pressure relief valve; the horizontal pipe (4) being provided by a first connection means (8A) for removably connecting at a first end to the pressure relief valve (2) and by a second connection means (8B) for removably connecting at a second end to the liquid trap element (1), the vertical exhaust pipe (3) being connected to the horizontal pipe (4) between the first end removably connectable to the pressure relief valve (2) and the second end removably connectable to the liquid trap element (1).
