Pressurized relief tank for steam

摘要

A pressurizer relief or surge tank for connection with the pressurizer of a pressurized-water coolant system, has the usual tank partly filled with water and with a pressurized-gas cushion above the water. For more uniform relief action, the bottom of the tank contains a distribution pipe means rather closely fitting the inside contour of the tank and having a large number of distributing holes in its upper periphery, both transversely and circumferentially, a pipe having an upper end for connection with the coolant pressurizer, extending through the top of the tank and down to the pipe means in the tank's bottom, where the pipe connects with the pipe means by a system of radial connecting pipes.
