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.
