201486 · 1. Process Description: The gasifier feed system consists of weight bins, conveyors, and lock hopper systems that supply the gasifier with coal at pressure. The coal feed is pressurized in a lock hopper system and metered into the gasifier using a rotary or screw feeder.
Lock hoppers provide a means of both allowing operation of many feeding devices that have only a lowpressure capability, to operate at very much higher pressures, and allowing continuous conveying from a single blowtank feeder. The lock hopper is located between the supply hopper, which will generally be at atmospheric pressure to allow ...

Rotary feeders are primarily used for discharge of bulk solid material from hoppers/bins, receivers, and cyclones into a pressure or vacuumdriven pneumatic conveying system. Components of a rotary feeder include a rotor shaft, housing, head plates, and packing seals and bearings.
UNDERSTANDING AND PREVENTING FINE POWDER FLUSHING When a fine powder traps air between particles, it may exit the bin like it is in a pneumatic conveyor system, shooting through any crack or crevice, including poorly fitting or worn rotary valve vanes, screws, feeders, bolt holes, vibratory feeder .
Dry Coal Feed Shell and Siemens gasifiers are examples that use a dry coal feed system. Dry feed systems use a lock hopper operating in a batch mode, intermittently charging coal fines into the pressurized gasifier via staged opening and closing of valves on .
Coal industry Diamondback Hopper.
