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. Note that due to how the variables are used in the modeling equations, the range of acceptable values may be further reduced; for more details, see Steam Generation: Modeling Assumptions & Constraints.

The following list describes the available specification choices in this tab; for more details on how these are implemented, see Steam Generation: Modeling Calculations.
•Composition of Combustible Fuel Components...
You only need to specify the molecular composition (in mass percentage) of those pure components of the fuel stream that correspond to combustible fuel (such as methane). For each combustible fuel component of the fuel stream, specify the elemental composition in terms of carbon, hydrogen, oxygen, nitrogen, and sulfur, as well as the moisture and ash composition. You must make sure that the total composition is 100%.
You do not need to specify the composition of other pure components (e.g., oxygen, nitrogen, water, ash).
