Abstract
A system and method for a multistage condenser is described that reduces problems associated with temperature and pressure differential strains on tubes above and below a dead tube. Instead of connecting the dead tube to the I/O manifold, a physical separation is created. The physical separation can be created by shortening the dead tube, coring a portion of the I/O manifold where the dead tube is received, independent I/O manifolds, or other means.
