Present embodiments include systems and methods for reducing variations in a solid feed provided to a gasifier. For example, in an embodiment, a gasification feed vessel includes a solid fuel inlet configured to receive a solid fuel into the gasification feed vessel, a dry mixer configured to dry mix the solid fuel within the feed vessel, a solid fuel outlet configured to deliver a feed of the solid fuel to a gasification system, and a metering device coupled to the solid fuel outlet. The metering device is configured to control an amount of the feed of the solid fuel delivered to the gasification system. The gasification feed vessel is configured to provide the feed of the solid fuel to the gasification system within a desired energy concentration range over time.
