Abstract
In a heat exchanger fueled by a metal-corroding heating gas, the use of a replaceable aluminum plug component which, because of its chemical affinity, corrodes first to thereby obviate the corroding of other non-replaceable metal components, to thereby contribute to eliminating malfunctioning due to corrosion. The construction of the plug also contributes to the heat transferring efficiency of the heat exchanger.
