  • Good accessibility for maintenance and a compact design. Modular and expandable with additional JUMAG steam boilers

How it works

In contrast to the traditional steam generator (water tube boiler with pipe coil and piston pump), JUMAG steam boilers work as follows:

  • The feed water in the pressure vessel is topped up by the boiler pump through the economiser depending on the water level in the pressure tank.
  • The burner is controlled depending on the steam pressure. Multi-lane flue gas routing transfers the heat from the flue gas through the pressure vessel to the water.
  • In the economiser, additional heat from the flue gas is transferred to the fresh water in the counter flow. The steam is dried in the inner system of the pressure vessel.
