Abstract: The present invention is generally directed toward an apparatus and method for the heating of vaporized aqueous mixture, more specifically toward the pre-heating a vaporization chamber. In a power plant utilizing a cleaning process, such as a selective catalytic reduction (SCR) process, or other type of process, to remove harmful components, such as nitrous oxide (NOx), from a stream of flue gas wherein the cleaning process includes the injection of vaporized aqueous mixture into the stream of flue gas, the present invention comprises a vaporizing chamber having a heat source to facilitate the heating and subsequent vaporization of the ammonia.

Abstract: An apparatus for the distribution of cooling air having a cooling air distribution housing having an exterior wall, an interior wall, an inlet end and an outlet end defining a substantially circular passage therethrough, a cooling air providing assembly provides cooling air to the cooling air distribution housing and a plurality of cooling air distribution conduits before proving passage of the cooling air from the cooling air distribution housing into the substantially circular passage. Each of the plurality of cooling air distribution conduits having an inflow end and communication with the cooling air distribution housing and an outflow end extending into the substantially circular passage.
