Gasifier: Equipment Tab

Variable Definitions, Ranges and Default Values

The following table shows the meaning of the variables appearing in this tab, as well as their default values and their generally acceptable range. Note that due to the manner by which the variables are used by the sizing and costing equations, the range of acceptable values may be further reduced.

Variable	Default Value	Range

◙ Fuel Throughput (MT/h) The mass flow rate of fuel.	0.0	Positive
○ Maximum Fuel Throughput (MT/h) The desired upper limit of the sizing variable. Used only in design mode to determine if multiple units are required.	100.0	Positive

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

Sizing: Design Mode

In design mode, the software will size the unit based on the demand on fuel throughput by the gasification operation executed in the unit. If the fuel throughput exceeds the specification for the maximum fuel throughput then the software will assume multiple number of identical units (each with fuel throughput equally distributed) that are operated in parallel.

Sizing: Rating Mode

In rating mode, the fuel throughput and the number of units are provided by the user.

Costing

Currently there is no built-in purchase cost model for this equipment. The user-defined equipment purchase cost model is based on the fuel throughput.
