ABSTRACT:
A tube-in-tube heat exchanger for exchanging heat between two fluids is provided. The heat exchanger has at least one tube pair; spaced apart first and second tube sheets; first and second annular flow chambers; and first and second inner tube flow chambers. A gasket surrounds each inner tube of each tube pair at each end, forming a seal between each annular flow chamber, each inner tube flow chamber, and each inner tube. Such configuration allows for modular construction and easy cleaning and replacement of fouled or damaged tubes.
