Fuel-Air Combustion: Components Tab

This tab appears on the interface dialog of the following operations:

● Continuous Stoichiometric Reaction in a Rotary Kiln

● Power Generation in a Gas Turbine-Generator

● Power Generation in an IC Engine-Generator

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

○ Oxygen Indicates the pure component associated with oxygen. Click on the list box to bring up a list of available components in order to select one.	<Oxygen>	Any Pure Component
○ Water Indicates the pure component associated with water. Click on the list box to bring up a list of available components in order to select one.	<Water>	Any Pure Component
○ Nitrogen Indicates the pure component associated with nitrogen. Click on the list box to bring up a list of available components in order to select one.	<Nitrogen>	Any Pure Component
○ Carbon Dioxide Indicates the pure component associated with carbon dioxide. Click on the list box to bring up a list of available components in order to select one.	<none>	Any Pure Component
○ Sulfur Dioxide Indicates the pure component associated with sulfur dioxide. Click on the list box to bring up a list of available components in order to select one.	<none>	Any Pure Component

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 Power Generation in a Gas Turbine-Generator: Modeling Calculations or Power Generation in an IC Engine-Generator: Modeling Calculations.

Through this tab, you must select a pure component for each different kind of molecule that may be present in the combustion gas (unburned oxygen, water vapor, nitrogen, carbon dioxide and sulfur dioxide). By default, the oxygen, water and nitrogen molecules are associated automatically with pure components “Oxygen”, “Water” and “Nitrogen”, respectively, of the Designer database. The carbon dioxide molecule will be also associated with an appropriate pure component (one with the same name and molecular weight) if one exists. Similarly, the sulfur dioxide molecule will be associated with an appropriate pure component if one exists.

•Register Pure Components

It is possible to introduce new pure components in the process by simply clicking on this button:

This will present you with the Pure Component Registration Dialog that allows you to register new pure components without exiting the stoichiometry balance and the operating conditions dialogs.
