Abstract

PURPOSE:To make it possible to conduct leakage checking for sure by providing a bend tube of a vertical type low pressure water cooling pipe in the furnace that has a slip joint section with differential pressure take-out openings at two places. CONSTITUTION:Differential pressure take-out openings are installed at two places in the bend of the lower inlet of a vertical type LPCI piping in the furnace. Those openings are for measuring leakage that is the same as the sum of the volume of leakage from those two places and the total volume of leakage from a vent hole 9. With this arrangement it is possible to check leakage for sure from the slip joint in the ordinary operation, and it becomes possible to take measures for drop in the plant efficiency and large leakage, so that the maintanence of the piping in the furnace can be carried out for sure.
