Patent number: 10131857Abstract: A system includes a quench system that may cool a syngas generated in a gasification chamber. The quench system includes a quench chamber, a dip tube that may direct the syngas from the gasification chamber into a quench liquid to cool the syngas to generate a cooled syngas, a draft tube disposed circumferentially about the dip tube and that may receive the cooled syngas in a first direction. A first passage is disposed between a first wall of the dip tube and a second wall of the draft tube. The system also includes a first baffle that may receive the cooled syngas from the first passage. The first baffle may split a flow of the cooled syngas into a first syngas flow and a second syngas flow, and the first baffle may redirect the first syngas flow in a second direction different from the first direction.Type: GrantFiled: February 9, 2017Date of Patent: November 20, 2018Assignee: General Electric CompanyInventors: John Saunders Stevenson, Pravin Sadashiv Naphade
