Abstract

See full text

Systems and methods for starting a gasifier are provided. In the method, a heated start-up medium can be fed to a gasifier operating at a first temperature. Heat can be transferred from the heated start-up medium to the gasifier to increase the temperature of the gasifier from the first temperature to an intermediate temperature sufficient to auto-ignite a start-up fuel. A start-up fuel and an oxidant can be fed to the gasifier after the temperature within the gasifier is increased to the intermediate temperature. At least a portion of the start-up fuel can be combusted within the gasifier to produce a combustion gas. Heat can be transferred from the combustion gas to the gasifier to increase the temperature of the gasifier to an operating temperature, wherein the operating temperature is sufficient to gasify at least a portion of a hydrocarbon feedstock.
