Adaptive Control System For Reagent Distribution Control In Scr Reactors
US Patent:
2009011, Apr 30, 2009
Filed:
Oct 30, 2007
Appl. No.:
11/980047
Inventors:
Rajaram Jambhekar - Randolph MA, US
Robert Lisauskas - Shrewsbury MA, US
William Medeiros - Leominster MA, US

International Classification:
G05B 15/00
US Classification:
700266
Abstract:
A method for controlling dosage of a reagent in a selective catalytic reduction (SCR) system includes the step of providing the system with a plurality of reagent injection nozzles, each nozzle being configured and adapted to be independently calibrated during an SCR reaction when the system is in operation. The method further includes determining an influence coefficient for each injection nozzle for a catalyst independently of the other injection nozzles, and optimizing the flow of reagent from each injection nozzle to minimize a sum of deviation across a surface of the catalyst. A system performs selective catalytic reduction (SCR) and a machine readable medium contains program instructions to controlling dosage of a reagent in a selective catalytic reduction (SCR) system.
