Abstract:
1. A gasification system, comprising: a gasifier comprising a gasification region, a gasifier inlet positioned above the gasification region, a gasifier outlet positioned below the gasification region, and an outer wall surrounding the gasification region; a first fuel source configured to supply a first fuel to the gasifier while the gasifier is in operation, wherein the first fuel comprises a liquid fuel, a slurry fuel, or a combination thereof; and a first fuel path comprising a heat exchanger portion and a fuel injection portion, wherein the heat exchanger portion extends along the outer wall, the heat exchanger portion comprises a heat exchanger inlet and a heat exchanger outlet, the heat exchanger inlet is fluidly coupled to the first fuel source, the heat exchanger outlet is positioned above the heat exchanger inlet, and the fuel injection portion is fluidly coupled to the heat exchanger outlet and to the gasifier inlet; wherein the heat exchanger portion is configured to receive the first fuel from the first fuel source at the heat exchanger inlet and to flow the first fuel to the heat exchanger outlet along the outer wall to cool the gasifier while the gasifier is in operation; and wherein the fuel injection portion is configured to receive the first fuel from the heat exchanger outlet and to inject the first fuel into the gasifier inlet while the gasifier is in operation.
