METHOD FOR PREVENTING FOULING OF EXHAUST GAS FLOW PATH OF BURNING EQUIPMENT AND METHOD FOR REMOVING AMMONIUM HYDROGEN SULFATE CONTAINED IN EXHAUST GAS OF BURNING EQUIPMENT

摘要

Provided is a method for effectively preventing fouling of an exhaust gas flow path of a burning equipment due to ammonium hydrogen sulfate; and thus, the method for preventing fouling of an exhaust gas flow path of a burning equipment in the present invention comprises: a step of adding a tertiary amine and/or a quaternary ammonium compound to an exhaust gas which contains ammonium hydrogen sulfate which is generated in a burning equipment thereby forming a reaction product between the ammonium hydrogen sulfate and the tertiary amine and/or the quaternary ammonium compound, and a step of controlling a temperature and a relative humidity in at least a part of an exhaust gas flow path of the burning equipment in such a way that the reaction product may be kept in a solid state.
