01 / FOLLOW THE DUTY
From steam
to airflow.
Choose boiler output, fuel and operating conditions. Follow the calculation from combustion demand to the flow the fan must move.
01 / Equipment & energy
Every pascal.
Every kilowatt.
Connected.
A boiler breathes through two fans. Follow the air, open the machine and see how the duty becomes a fan selection.

Start with a question
Where does the
energy actually go?
From steam
02 / OPEN THE MACHINE
See what each
part does.
Move between assembled, cutaway and exploded views. Inspect the impeller, shaft and bearings in the existing interactive lab.
03 / COMPARE CHOICES
Pressure has
a power cost.
Explore system resistance and compare damper control with variable speed at part load. Review the assumptions behind the savings.
Your next five minutes
Try one boiler.
Then change the load.
Start with the forced-draught fan, switch to induced draught, then explore the savings tab. Watch how the same boiler creates different duties.
Open the interactive lab ↗First-pass design examples for learning and budgeting. Final equipment selection needs verified duty and manufacturer-tested performance.
