HEAT RECOVERY TEST APPARATUS AND METHOD FOR MAKING AND TESTING THE SAME

摘要

A test apparatus for testing the tube-to-header connections in a heat recovery system in which a plurality of tubes (18-20) is connected to a header (11) via tube-to-header connections. The test apparatus includes a source of test gas, a shroud (21) surrounding the tube-to-header connections and a test gas detector (44) in communication with the chamber (17) within the shroud (21). The invention also relates to a method of testing the tube-to-header connections by forming a test chamber surrounding the tube-to-header connections, introducing a test gas into the chamber and then detecting the level of test gas in the chamber.
