Patent number: 8108073Abstract: 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.Type: GrantFiled: July 13, 2011Date of Patent: January 31, 2012Assignee: Babcock Power Environmental Inc.Inventors: Rajaram Jambhekar, Robert Lisauskas, William Medeiros, Clayton Erickson

Publication number: 20110320943Abstract: An adaptive and interactive training system and method is provided. The system provides training content to a user of an application program based upon a variety of factors. The system selects the training content based upon the user's individualized needs vis-à-vis an application program. The system may customize the training sent to the user by evaluating the user's actual interaction with the application program, the user's personal profile and the group profile of groups to which the user belongs.Type: ApplicationFiled: June 29, 2010Publication date: December 29, 2011Applicant: Brainstorm, Inc.Inventors: John Wade, Derek Adams, Christopher Mascis, Clayton Erickson Farr, Jeff House, Robert Barker, JR., Casey Margell

Patent number: 8017100Abstract: The invention provides a system for converting urea into reactants useful for removing NOX from industrial emissions. The system includes a urea inlet, a steam inlet, and a reactor in fluid communication with the urea inlet and the steam inlet. The reactor is configured and adapted to inject urea from the urea inlet into a steam flow from the steam inlet to convert the urea into at least one reactant for NOX reduction within a substantially gaseous mixture. The invention also provides a method of converting urea into reactants for reducing NOX out of industrial emissions. The method includes injecting urea into a steam flow to convert the urea into at least one reactant for NOX reduction within a substantially gaseous mixture.Type: GrantFiled: September 28, 2009Date of Patent: September 13, 2011Assignee: Babcock Power Environmental Inc.Inventors: Calvin E. Phelps, Sr., Clayton A. Erickson, Rajaram Jambhekar, John R. Harold

Patent number: 7682586Abstract: This invention relates generally to the treatment of NOx in combustion flue gas. In certain embodiments, the invention relates to the use of a regenerative heat exchanger (RHE) to convert urea to ammonia in a side stream of flue gas. Ammonia and/or other urea decomposition products exit the heat exchanger, are mixed with the rest of the flue gas, and enter a selective catalytic reduction (SCR) unit for reduction of NOx in the flue gas. The use of an RHE significantly improves the thermal efficiency of the overall process. More particularly, in certain embodiments, the regenerative heat exchanger is a dual chamber RHE.Type: GrantFiled: August 22, 2007Date of Patent: March 23, 2010Assignee: Babcock Power Environmental, Inc.Inventors: John R.
