PURPOSE:To enhance the density of heat accumulation and to obtain steam of good quality by circulating the water stream in an accumulator forcedly from below toward above immediately before completion of steam injection into a pressure vessel and immediately before commencement of releasing and taking out. CONSTITUTION:Steam storage in an accumulator is made by injecting the steam P from a steam blow-in nozzle 3 into water W contained by a pressure vessel 1, where high-pressure steam P' is blown in from a nozzle 9 for injection of the steam for warming the air immediately before completion of this injection or, as another process, a water stream from below toward above is caused forcedly by a circulation system using a pump 10, in order to make uniform the temp. distribution for the purpose of enhancing the density of heat accumulation. Immediately before commencement of release and takeout, a water stream likewise from below toward above is caused previously for a short while. Thus bumping is prevented to ensure stable self-evaporation, and now a steam of good quality can be obtained which does not contain any water drops. |
