Abstract: A feed injector for a gasifier comprising a burner and a cooling jacket to protect the burner from high temperatures. The cooling jacket comprises two concentric channels in order to provide a flow path for a heat transfer fluid, typically water, to travel through one channel toward the burner front, travel along the burner front, and return through the other channel. Heat transfer in the cooling jacket is improved by introducing one or more fins in the path of the heat transfer fluid and/or by increasing the radius of curvature of the wall corner bordering the flow recirculation zone in the cooling jacket.

Abstract: Process, reactor and burner for the gasification of a hydrocarbon fuel. The burner comprises coaxial channels for the separate supply of an oxidizer gas, a hydrocarbon fuel and a moderator gas. A coaxial channel with the smallest width is bordered by a separating wall with at least one gas exchange. The gas exchange passage can for example be formed by a retracted end of the separating wall and/or by openings in the separating wall.

Abstract: Gasification reactor and process for the production of synthesis gas by partial combustion of a carbonaceous feed. The reactor comprises a reactor chamber with one or more burners and at least one oil lance extending into the reactor chamber. The oil lances can for instance be located at a level 1.5 meters or less below or above the burners.
