Abstract
Present embodiments include systems for reducing moisture in a solid feed provided to a gasifier. For example, in an embodiment, a feedstock preparation system includes an aspirator having a first inlet for receiving a flow of steam, a second inlet for receiving a flow of a moist gaseous phase from a grinding mechanism configured to grind a solid fuel in the presence of a conveyance gas. The moist gaseous phase includes the conveyance gas and moisture removed from the ground solid fuel. The aspirator also includes an outlet configured to output a reduced pressure flow having the steam and the moist gaseous phase. The aspirator is configured to enhance moisture removal from the ground solid fuel to produce a dry feed of the ground solid fuel. The aspirator discharge is recycled within the process to heat the incoming dry conveyance gas and improve system efficiency.
