Patent number: 10329979Abstract: A method for controlling an emission amount in an exhaust gas stream emitted from a power generation system is presented. The method includes determining a pre-catalyst emission level using a combustion engine model. The method further includes determining a post-catalyst emission level using a three-way catalyst model based on the pre-catalyst emission level. Furthermore, the method includes determining an adjusted post-catalyst emission level based on the post-catalyst emission level. Moreover, the method includes determining a difference between the post-catalyst emission level and the adjusted post-catalyst emission level and comparing the difference with a threshold value. Additionally, the method includes determining whether to adjust an actual value of an engine operating parameter based on the comparison such that the emission amount in the exhaust gas stream is maintained below an emission regulatory limit. An engine controller and a power generation system employing the method are also presented.Type: GrantFiled: September 15, 2016Date of Patent: June 25, 2019Assignee: AI ALPINE US BIDCO INCInventors: Prashant Srinivasan, Maruthi NarasingaRao Devarakonda, William Collins Vining, Edward Owen Reinbold, Dipankar Deb

Patent number: 10245539Abstract: A filter system and method use a filter housing that defines an interior chamber and that includes an inlet opening extending into the interior chamber. The outer air flow housing has an outlet conduit through which a flow of air having particles is directed toward the inlet opening of the filter housing along a flow direction toward the interior chamber of the filter housing. The outer air flow housing engages the filter housing such that the filter housing is separated from the outer air flow housing along the flow direction to permit at least some of the air to pass around an exterior of the filter housing and exit the outer air flow housing while the particles in the at least some of the air pass into the interior chamber of the filter housing through the inlet opening.Type: GrantFiled: November 5, 2015Date of Patent: April 2, 2019Assignee: General Electric CompanyInventors: William Collins Vining, Robert Francis Manning, Victor Hugo Silva Correia, Corey Bourassa, Jared Peter Buhler, Hojjat Nasr
