<P>PROBLEM TO BE SOLVED: To provide a liquid film forming cap with which a uniform liquid film can be formed in an inner circumferential wall of a heat transfer tube even when installation shift is caused by manufacturing error or the like in a tube plate or the heat transfer tube. <P>SOLUTION: The liquid film forming cap 1 is disposed in an upper end opening of the heat transfer tube 15 which is vertically arranged, and forms a thin film on a surface of the heat transfer tube by making a liquid stored in an upper part of the heat transfer 15 flowing into the heat transfer tube 15. The liquid film forming cap 1 includes: a hollow cylindrical cap body 2 where a top surface is sealed and a bottom surface 4 is opened; and a notch part 5 that is formed on a circumferential wall of the cap body 2 and where liquid vertically extends from the top surface in the direction with a rotational flow. <P>COPYRIGHT: (C)2012,JPO&INPIT |
