Incineration: Oper. Conds Tab

Variable Definitions, Ranges and Default Values

The following table shows a brief description of the variables appearing in this tab. The table also displays their default values and their generally acceptable range:

Variable	Default Value	Range

● Fuel Stream Indicates the input port that is connected to the stream that is used as fuel source. If an inlet stream is already present at the selected port, then the button next to the selection is active. Click on the button to bring up the attached stream’s simulation dialog in order to provide its composition.	<None>	Dedicated Input Port
○ Adjust Fuel Flow for Complete Combustion of Waste Check this box to adjust the flowrate of the fuel stream for complete combustion of the waste stream.	Yes	Yes/No
● Fuel Requirement for Complete Combustion The mass of fuel required per mass of waste for complete combustion of waste.	0.0	Positive
● Air Stream Indicates the input port that is connected to the stream that is used as oxygen source. If an inlet stream is already present at the selected port, then the button next to the selection is active. Click on the button to bring up the attached stream’s simulation dialog in order to provide its composition.	<None>	Dedicated Input Port
○ Adjust Air Flow Check this box to adjust the flowrate of the air stream.	Yes	Yes/No
◙ Excess Oxygen (%) The % excess oxygen of the air stream.	25.0	0-100
● Relative Humidity of Entering Air (%) The % relative humidity of the air stream.	0.0	0-100
○ Ash to Flue Gas (%) The %ash that is entrained in the flue gas stream.	0.0	0-100
○ Flue Gas Temperature (^oC) The temperature of the flue gas stream after energy recovery.	250.0	Positive
● Excess Heat The excess heat of the fuel stream with respect to that for complete combustion of the waste stream expressed as energy per mass of the waste stream.	0.0	Positive

Symbol Key: ○ User-specified value (always input); ● Calculated value (always output); ◙ Sometimes input, sometimes output

Specification Choices / Comments

The following list describes the available specification choices in this tab; for more details on how these are implemented, see Incineration: Modeling Calculations.

•Ash to Flue Gas (%) ...

The Ash to Flue Gas (%) parameter determines the percentage of ash that is entrained by the flue gas stream. By default, all generated ash exits in the bottom stream.
