Title (EN) METHOD IN CLEANING FLUE GAS IN A PFBC PLANT INCLUDING A GAS TURBINE DRIVEN THEREBY
(FR) PROCEDE D'EPURATION DE GAZ DE COMBUSTION DANS UNE INSTALLATION PFBC COMPRENANT UNE TURBINE A GAZ ENTRAINEE PAR CEUX-CI
Abstract:
(EN) The invention refers to a method in cleaning flue gas in a PFBC plant including a gas turbine driven thereby, wherein the reduction of the NOx content in the flue gas is accomplished by thermal reduction by injecting ammonia into the flue gas flow to the gas turbine and then accomplished catalytically entailed reduction in the presence of ammonia in the flue gas flow from the gas turbine.
(FR) Procédé d'épuration de gaz de combustion dans une installation PFBC (à chaudière à un ou à plusieurs lits fluidisés sous pression) comprenant une turbine à gaz entraînée par ceux-ci, dans lequel la réduction de la teneur en NOx des gaz de combustion est accomplie par réduction thermique par injection de gaz ammoniac dans le flux de gaz de combustion dirigé vers la turbine à gaz, puis par réduction provoquée de manière catalytique en présence de gaz ammoniac dans le flux de gaz de combustion provenant de la turbine à gaz.
