Abstract
The present invention discloses an exhaust gas conduit for feeding exhaust gases to a scrubber wherein the conduit is equipped with a self-cleaning device mounted inside the conduit body adjacent to an outlet end of the conduit for dispensing a cleaning solvent onto the inside wall of the outlet end of the conduit such that solid depositions on the inside wall can be avoided. The present invention is also directed to a method for preventing solid depositions in an exhaust gas inlet port to a wet scrubber by utilizing a self-cleaning device mounted in a conduit adjacent to an outlet end of the exhaust conduit and by dispensing a cleaning solvent through the self-cleaning device and spraying the solvent onto an inside wall of the outlet end of the conduit to prevent the formation of solid depositions on the inside wall.
