The Shell Gasifier Diagram result screen shows the major flows into and out of the Shell gasifier unit:


IGCC: GET RESULTS: Gasifier Area: Shell: Shell Gasifier Diagram

Each result is described briefly below:

Area 1

Cold Gas Eff.: This is the ratio of the heat contents calculated at room temperature of the syngas fuel output and the coal fuel input. The higher heating value is used here.

Area 2: Flows Entering the Gasifier

Temperature In: This is the temperature of the oxidant stream into the gasifier.

Oxidant In: This is the mass flow of oxidant into the gasifier.

Steam In: This is the flow rate of steam used for the coal slurry into the Shell entrained-flow gasifier.

Dried Coal In: This is the flow rate of dry coal into the Shell entrained-flow gasifier. The coal flow rate is on a wet basis.

Area 3: Coal Entering the Dryer

Wet Coal: This is the flow rate of wet coal entering the coal dryer.

Area 4: Slag

Sluice Water: Slag collected can be removed from the gasifier and disposed by sluicing the slag with water.

Wet Slag: Slag collected is removed from the gasifier. Sluice water may or may not be used to facilitate its transportation. This is the total slag flow rate leaving the gasifier on a wet basis.

Area 5: Flows Exiting the Gasifier

Temperature Out: This is the syngas temperature exiting the Shell entrained-flow gasifier.

Pressure Out: This is the approximate pressure of the syngas exiting the Shell entrained-flow gasifier.

Syngas Out: This is the mass flow rate of syngas exiting the Shell entrained-flow gasifier.

Syngas Out: This is the volumetric flow rate of syngas exiting the Shell entrained-flow gasifier.
