<p>The device comprises condensate collecting trays (8, 9), a tank (10) receiving the water falling from the trays, a reheating device situated at the bottom of the tank, consisting of tubing (14) fed with steam at average pressure, the steam escaping through rows (14, 16) of holes and condensing within the water of the tank, the said tank comprising at its upper part at least one overflow-pipe (11) towards the bottom of the well (7) of the condenser, and furthermore comprising at least one additional deaerating device, characterised in that it is situated at a level slightly above the said reheating device and consists of horizontal tubing (17), the said tubing comprising throughout its length, on the said overflow-pipe (11) side, a perforated zone (19), and being traversed by steam at very low pressure, slightly greater than the pressure of the condenser, the said perforated zone enabling the lower part of the cross-section of the tubing (17) to be filled with water from the tank and enabling the steam to escape from the tubing out of the tank, the upper part of the said perforated zone being situated at a level slightly below that of the said overflow-pipe. <IMAGE></p> |
