Publication number: 20170335734Abstract: The present application provides a selective catalyst reduction system for use with a combustion gas stream of a gas turbine. The selective catalyst reduction system may include a tempering air system with a finger mixer and a number of mixer plates and a catalyst positioned downstream of the tempering air system. The tempering air system cools the combustion gas stream and evens out the temperature profile before the combustion gas stream reaches the catalyst.Type: ApplicationFiled: May 19, 2016Publication date: November 23, 2017Inventors: Ali Mustapha Tabikh, John Buschmann, Lawrence Joseph Czarnecki, Lars-Erik Johansson

Patent number: 9643117Abstract: An air quality control system (AQCS) 14 useful for treating flue gas FG, such as flue gas FG produced by a fossil fuel fired boiler 12 is described. The AQCS 14 is equipped with a dust separator 37. The dust separator 37 is useful under relatively high dust load conditions downstream from a dry scrubber reactor 36 with limited equipment wear and limited space requirements. As such, the dust separator captures particulate matter with a dust trap that intercepts the flow of particulate matter for collection of the particulate matter in a hopper.Type: GrantFiled: September 29, 2015Date of Patent: May 9, 2017Assignee: General Electric Technology GmbHInventors: Robert Råhlin, Ali Mustapha Tabikh

Patent number: 9453460Abstract: The invention pertains to fluegas recirculation in gas turbines, and specifically to an intake section upstream of the inlet of a compressor of a gas turbine unit with fluegas recirculation. The intake section includes at least one section with a flow path defined by sidewalls in which the fresh airflow of the intake air is flowing along a principal airflow direction, including at least one mixing duct extending into the flow path from at least one sidewall. The mixing duct includes an intake at the at least one sidewall for receiving recirculated fluegas, as well as including at least one outlet opening distanced from said sidewall for blowing recirculated fluegas out of the mixing duct into the airflow.Type: GrantFiled: July 23, 2013Date of Patent: September 27, 2016Assignee: GENERAL ELECTRIC TECHNOLOGY GMBHInventors: Eribert Benz, Niclas Lars Olof Lindqvist, Ali Mustapha Tabikh, Lars Filip Lundin
