Emission Factors

← Previous | Next →

Inputs for the gas turbine emission factors are entered on the Emission Factors parameter screen . This screen is available for both the NGCC and IGCC plant types. The following parameters are available:

•Percent SOx as SO3: This is the volume percent of SOx that is SO3. The remainder is SO2.

•NOx Emission Rate: This is the concentration of NOx emitted from the gas turbine after combustion.

•Percent NOx as NO: This is the volume percent of NOx that is NO. The remainder is NO2.

•Percent Total Carbon as CO: This is the volume percent of the total carbon in the syngas entering the combustor that is emitted from the gas turbine as CO.
