Inputs for the performance of the GE gasifier are entered on the Performance parameter screen. The following parameters are displayed:

Gasifier Area:

Gasifier Temperature: This is the temperature of the syngas exiting GE Entrained-Flow Reactor. You may choose from the following values:

2350°F

2450°F (this is the default)

2550°F

Gasifier Pressure: This is the pressure of the syngas exiting GE Entrained-Flow Reactor. This value is provided for reference only.

Total Water or Steam Input: This is the ratio of water to carbon in the coal slurry.

Oxygen Input from ASU: The GE gasifier requires a constant value for the oxygen (O2) in the oxidant to carbon (C) in coal ratio. This value is provided for reference only.

Total Carbon in Slag: This the percent of carbon in the fuel that is lost in the slag. You may choose from the following options:

1

3 (this is the default)

5

Sulfur Loss to Solids: This is the percent of the sulfur in coal that is lost in the slag.

Coal Ash in Raw Syngas: This is the percent of ash in the coal that is in the syngas.

Percent Water in Slag Sluice: This is the percent of the slag sluice that is water.

Number of Operating Trains: This is the total number of operating trains. It is used primarily to calculate capital costs. The value must be an integer.

Number of Spare Trains: This is the total number of spare trains. It is used primarily to calculate capital costs. The value must be an integer.

Raw Gas Cleanup Area:

Particulate Removal Efficiency: This is the percentage of the ash which is removed by the raw gas cleanup process.

Power Requirement: This is the equivalent electrical output of thermal (steam) energy used for reheat, plus the actual electrical output power required.
