"System And Method For Dry Feed Gasifier Start Up"
Abstract: A gasification system (100) including a gasifier (102) and a fuel feed system (104) coupled in flow communication with the gasifier. The fuel feed system includes a first feed line for injecting conveyance gas and dry fuel into the gasifier, a second feed line (112) for injecting a slurry of coal or a moderator into the gasifier, a stabilization fuel line (114) for injecting a stabilization fuel or a moderator into the gasifier, and a fuel feed system controller (106) comprising a processor. The processor is programmed to enable the stabilization fuel line to inject the stabilization fuel into the gasifier to initiate a stabilizer flame inside the gasifier, enable the first feed line to inject the dry fuel into the gasifier at a start-up dry fuel flow rate, increase the flow rate of the dry fuel from the start-up dry fuel flow rate to a normal operating condition dry fuel flow rate, decrease a flow rate of the stabilization fuel as the flow rate of the dry fuel increases to the normal operating condition dry fuel flow rate, and prevent the stabilization fuel line from injecting the stabilization fuel into the gasifier once the flow rate of the dry fuel is at the normal operating condition dry fuel flow rate or a gasifier reaction is stable. fig. 2
