A Fire Heater Simulator to demonstrate changes when altering operation variables https://estebmaister.github.io/fh-simulator/

Fire-Heater Simulator

Running it locally

Make sure you have node installed and run this simulator with the following command in the terminal:

node . false SI 26.6667 50 0 20 1.01325e5

Arguments:

1. [boolean] Verbose logs at the console
2. [string] Unit System (SI)
3. [number] Ambient temperature (°C)
4. [number] Relative humidity (0-100%)
5. [number] O2 excess (0-30%) // if greater than possible or equal to 0, Air excess is used.
6. [number] Air excess (0-1000%) // overshadowed by O2 excess
7. [number] Ambient pressure (Pa)

Data update

To update the data used in the simulator from the .csv table, run the following command:

npm run data

Changing the algorithm web version

To update the files used by the web version of the app, run the following command:

npm start
