Abstract

A fuel feed system for use in a gasification system includes a feed preparation section, a pressurization and conveyance section, and a slag additive section. The feed preparation section is configured to grind the fuel to a predetermined size and to adjust the moisture content within the particulate fuel. The pressurization and conveyance section is coupled in flow communication with the feed preparation section, and includes at least one solids pump configured to receive a flow of the particulate fuel at a first pressure and discharge the particulate fuel at a second pressure. The slag additive section is configured to feed a slag additive mixture into the gasifier and to substantially control the total water content within the gasification system.
