Abstract:
A gasification system including a first feed line, a second feed line, a stabilization fuel line, and a fuel feed system controller including a processor. The processor is programmed to enable the stabilization fuel line to inject a stabilization fuel into a gasifier to initiate a stabilizer flame inside the gasifier, enable the first feed line to inject a 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 (NOC) dry fuel flow rate, decrease a flow rate of the stabilization fuel as the flow rate of the dry fuel increases to the NOC 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 NOC dry fuel flow rate.
