Abstract
A method of startup for a gasification system includes assembling a fuel mixture for use by a gasifier at a fuel mixture assembly point, wherein the fuel mixture includes a quantity of particulate solid fuel and a quantity of non-ventable carrier gas. The method includes channeling the fuel mixture through a first conduit to a fuel mixture disassembly system including a non-ventable carrier gas removal apparatus, establishing a substantially steady flow of the fuel mixture within the first conduit, and redirecting the fuel mixture through a second conduit to the gasifier to facilitate gasifier startup.
Claims18
A gasification system comprising:
- a gasifier;
- a feed conduit comprising a downstream end coupled in flow communication with said gasifier and an upstream end configured to receive a fuel mixture comprising a quantity of particulate solid fuel and a quantity of carrier gas;
- and
- a gasifier startup system comprising:
- a branch conduit coupled in flow communication with said feed conduit at a location upstream from said downstream end, said branch conduit is configured to receive at least a portion of the fuel mixture from said feed conduit;
- and
- a fuel mixture disassembly system coupled in flow communication with said branch conduit, said fuel mixture disassembly system comprises at least one device configured to separate a substantial portion of the particulate solid fuel from the carrier gas, wherein a residual portion of the carrier gas remains in the substantial portion of the particulate solid fuel after separation, and a carrier gas removal apparatus configured to strip the residual portion of the carrier gas from the substantial portion of the particulate solid fuel.
A fuel feed system for use with a gasifier, said fuel feed system comprising:
- a feed conduit comprising a downstream end configured to couple in flow communication with the gasifier and an upstream end configured to receive a fuel mixture comprising a quantity of particulate solid fuel and a quantity of carrier gas;
- a startup conduit coupled in flow communication with said feed conduit at a location upstream from said downstream end, said startup conduit is configured to receive at least a portion of the fuel mixture from said feed conduit;
- at least one device coupled in flow communication with said startup conduit, said at least one device configured to separate a substantial portion of the particulate solid fuel from the carrier gas, wherein a residual portion of the carrier gas remains in the substantial portion of the particulate solid fuel after separation;
- and
- a carrier gas removal apparatus coupled in flow communication with said at least one device, said carrier gas removal apparatus configured to strip the residual portion of the carrier gas from the substantial portion of the particulate solid fuel.
