Functioning

The basic equipment

  • Double-walled pressure vessel similar to a small shell boiler
  • Low-maintenance centrifugal pump
  • Intuitive touch-screen controls in many languages
  • Integrated control cabinet
  • Additional safety devices above regulations: Safety valve, steam pressure limiter, exhaust temperature limiter, steam temperature limiter, low water level shut-off, pump pressure monitoring

The functioning

Depending on the water level in the pressure vessel, the feed water is replenished by means of the boiler pump via the economiser into the pressure vessel.

The burner is controlled depending on the steam pressure. Via multiple pass flue-gas routing, the heat transfer takes place through the pressure vessel on the water.

In the economiser additional heat is transferred from the flue gas to the fresh water in a counter current. In the inner part of the pressure vessel the steam is dried.
