  • 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
    Patent number: 9527030
    Abstract: 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.
