TREATMENT OF EMISSIONS IN POWER PLANTS

A method for injecting a reductant into an exhaust gas stream of a combustion turbine engine for selective catalytic reduction. The method may include the steps of: directing the exhaust gas stream through an exhaust duct; receiving the directed exhaust gas for treatment by a catalyst positioned wit...

Beschreibung
Zusammenfassung:	A method for injecting a reductant into an exhaust gas stream of a combustion turbine engine for selective catalytic reduction. The method may include the steps of: directing the exhaust gas stream through an exhaust duct; receiving the directed exhaust gas for treatment by a catalyst positioned within the exhaust duct; providing a reductant in a liquid state; pressurizing and heating the reductant in a manner that maintains the reductant in the liquid state; and injecting the heated, pressurized reductant into the exhaust gas stream such that the reductant flash vaporizes upon injection due to a pressure differential.
