过热蒸汽再利用装置及其使用方法;SUPERHEATED STEAM RECYCLING APPARATUS AND METHOD FOR USING SAME

摘要

本发明提供一种过热蒸汽再利用装置及其使用方法，有效活用利用完毕的过热蒸汽来抑制热量损失，并且抑制为生成过热蒸汽而从水生成饱和蒸汽的热量。前述过热蒸汽再利用装置包括：过热蒸汽生成部(3)；蒸汽供给流道(L1)，向过热蒸汽生成部(3)供给饱和蒸汽；过热蒸汽利用部(4)，被供给由过热蒸汽生成部(3)生成的过热蒸汽；蒸汽返回流道(L3)，使通过过热蒸汽利用部(4)的利用完毕的蒸汽返回过热蒸汽生成部(3)；以及流量计(8)，测量返回过热蒸汽生成部(3)的利用完毕的蒸汽的流量，根据应由过热蒸汽生成部(3)生成的期望的过热蒸汽的流量与由流量计(8)得到的利用完毕的蒸汽的流量的差，控制从蒸汽供给流道(L1)向过热蒸汽生成部(3)供给的饱和蒸汽的流量。; a steam supply flow path L1 for supplying saturated steam to the superheated steam generating part 3; a superheated steam utilization part 4 that is supplied with superheated steam generated by the superheated steam generating part 3; a steam return flow path L3 for returning used steam having passed through the superheated steam utilization part 4 to the superheated steam generating part 3; and a flowmeter 8 that measures a flow rate of the used steam returned to the superheated steam generating part 3, and on the basis of the difference between a desired flow rate of the superheated steam to be generated by the superheated steam generating part 3 and the flow rate of the used steam obtained by the flowmeter 8, controls a flow rate of the saturated steam to be supplied to the superheated steam generating part 3 through the steam supply flow path L1.
