EXHAUST GAS TREATMENT EQUIPMENT AND EXHAUST GAS TREATMENT METHOD IN MARINE ENGINE

摘要

PROBLEM TO BE SOLVED: To remove adherence deposition which firmly adheres on a heat transfer pipe via ammonium sulfate and acid ammonium sulfate which easily precipitate due to reduction agent leaked from NOx removal equipment.SOLUTION: Provided is an exhaust gas heating device 31 which heats a mixture of ammonium sulfate and/or acid ammonium sulfate etc. adsorbed in soot adhered on a heat transfer pipe 5a to temperature at which heat decomposition of the mixture is performed, before soot blow fluid is sprayed from a soot blow pipe 08.
