ABSTRACT:
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.
