Abstract
Garbage incinerator fumes containing water vapor and HCl are drawn downwardly over a cooled tube bundle (41) in a vertical heat exchanger (4), whereat the water vapor condenses and the HCl dissolves in the condensate, which then falls into a collection reservoir (43) for siphon removal. The fumes are maintained above their dew-point temperature throughout the process.
