摘要： A low-temperature steam generating device comprises a pressure reducing unit 2 that lowers the pressure of steam to below atmospheric pressure by means of a vacuum pressure reducing valve 3 and a cooling unit 4 that changes steam with reduced pressure into saturated steam by lowering the temperature of the steam. The vacuum pressure reducing valve 3 is controlled based on the pressure and temperature of the steam with reduced pressure, whereas the cooling unit has a spray nozzle 5 that sprays cooling liquid into a passageway 61 at the entry end of a cooler proper 6 through which the steam with reduced pressure is admitted. The cooler proper 6 has a cylinder 60 through which the steam with reduced pressure passes and multistage constricting plates 65 disposed in the cylinder.

摘要： A condensate recovering vacuum pump uses the condensate in a condensate tank as the boiler feed water. A circulating pump supplies the feed water to the feed-water ejection nozzle of a jet pump. The condensate collected from the steam trap of the steam-using equipment is returned to the condensate tank together with the feed water. The penstock of a tank water level gauge is connected to the condensate tank through a throttle orifice while the upper part of the penstock is connected to the condensate tank 14 through an equalizing pipe. Water-level sensors to detect the water levels required for control are provided in the penstock. The condensate recovered by the jet pump from the trap of the steam-using equipment contains leaked steam and residual air in the piping. The vacuum pump with the above provisions always assures detection of the correct mean value of the water level in the condensate tank by keeping the water level gauge immune to the influence of the pressurized gas from the jet pump even if the gush of the pressurized gas may temporarily raise the pressure in the space above the water surface in the condensate tank.

摘要： To ensure the effective recovery of the condensate from steam-using apparatus, together with leaked steam from the trap and residual air in the piping, a condensate recovering vacuum pump is equipped with a jet pump comprising a vacuum chamber into which a condensate inlet port opens, a convergent cylindrical segment opening into the vacuum chamber and having a constricting cross-sectional area, a throat segment adjoining the convergent cylindrical segment and having a substantially uniform cross-sectional area, a divergent segment flaring from the throat segment, and a nozzle having an orifice at the tip thereof that protrudes somewhat into the convergent cylindrical segment from the side of the vacuum chamber, with the inside wall of the tip of the nozzle flaring so that a jet stream expelled therefrom diverges toward the internal surface thereof near the rear end of the throat segment. The jet pump is disposed so that the feedwater ejected therefrom issues forth upward.
