SPECIFYING METHOD OF PERFORATED POINT IN VERTICAL MULTI-PIPE TYPE HEAT EXCHANGER

摘要

PROBLEM TO BE SOLVED: To provide a method for accurately specifying a perforated position of a tube, a partitioning plate or the like in a vertical multi-pipe type heat exchanger.;SOLUTION: In a vertical multi-pipe type heat exchanger in which a cylindrical vessel is partitioned into an upper chamber, an intermediate chamber and a lower chamber which are aligned in an axial direction by a partitioning plate, and the upper chamber and the lower chamber which sandwich the intermediate chamber are made to communicate with each other by one or more tubes, the inside of the tube is filled with liquid by being supplied with the liquid from an opening of the tube which opposes the upper chamber or the lower chamber, after that, a floating measurement instrument is floated on a liquid level by inserting the floating measurement instrument into the tube in which the liquid level of the liquid is lowered, a distance from the opening of the tube up to the liquid level is measured by using the floating measurement instrument, and a perforated point in the vertical multi-pipe type heat exchanger is specified by using the measured distance.;SELECTED DRAWING: Figure 2;COPYRIGHT: (C)2016,JPO&INPIT
