Fuel Unit
| Units: | - |
| Default Value: | 0 |
| Validation Rule: | Any Value |
| Description: | Unit the fuel is measured in |
| Detail: |
Fuel Unit sets the unit that applies to the input properties such as Price, Max Offtake, etc.
If the Fuel Unit is not set, the default unit is read from the settings in the Units of Data page of the Settings menu available from the ribbon in the GUI. The default units are:
| Property type | Metric | Imperial US |
| Fuel consumption by period | giga-Joule (GJ) | million British Thermal Units (MMBtu) |
| Fuel price | $/GJ | $/MMBtu |
| Fuel consumption in summary periods | tera-Joule (TJ) | billion British Thermal Units (BBTU) |
If Fuel Unit is set, you may select any one of a wide range of supported units. Refer to Commodity Unit for a list of units. Note that only a subset are relevant for Fuel Unit.
Unit works with Energy Density to determine the heat value of the fuel for use in the simulation.
Example
| Fuel | Unit | Energy Density ( MJ ) |
| Biomass | kg | 16 |
| Coal | t | 24000 |
| Gas | - | 0 |
| Oil | bbl | 0 |
| Fuel | Property | Value | Data File | Units |
| Biomass | Price | 0.5 | $/kg | |
| Coal | Price | 150 | $/t | |
| Gas | Price | 8 | $/GJ | |
| Oil | Price | 80 | $/bbl |
In this example:
- "Biomass" inputs are in kilograms (kg) and the energy density is 16 MJ/kg and the price is $0.5/kg
- "Coal" inputs are in tonnes (t) and the energy density is 24,000 MJ/t (24 MJ/kg) and the price is $150/t
- "Gas" inputs are in the default unit (GJ for metric) and Energy Density is not required to be input (it is 1000 MJ/GJ) and the price is $8/GJ
- "Oil" inputs are in bbl (barrels of oil) which has a default energy density of 6118 MJ/bbl and the price is $80/bbl
