Abstract:
Gasifier preheater fuel and moderator injection apparatus, systems and methods are provided. A preheater distributor ring is securely mounted within the shell dome of a gasification vessel, for the selective discharge of preheat fuel and oxidizer into the vessel during preheating operations, or for the selective discharge of moderating agents into the vessel during normal gasification operations.
Abstract:
A system includes a solids combining system with a solids mixing section having a mixing chamber and a plurality of solids inlets configured to supply one or more solids into the mixing chamber. The system also includes a solids breakup section having a plurality of fluid inlets configured to supply one or more fluids into the mixing chamber and a solids flow control section having a converging-diverging passage downstream of the mixing chamber.
Abstract:
A system includes a gasification feed injector that includes a tip portion with a first threaded portion, a coolant chamber disposed in the tip portion, and a coolant fluid conduit having a second threaded portion. The coolant fluid conduit is coupled to the tip portion adjacent to the coolant chamber via screwing of the second threaded portion into the first threaded portion.
