JUMAG steam boiler oil- or gas-fired

JUMAG steam boilers combine the advantages of a compact quick steam boiler with those of a robust shell boiler. Depending on the device, they deliver steam outputs of 160 – 1060 kg/h. This capacity can be multiplied with multiple units. The DG series is oil- or gas-fired.

JUMAG oil- or gas-fired steam boilers in detail

How it works

Why do JUMAG steam boilers require minimal maintenance and boast maximum energy efficiency? This is due to the fact that they work differently from the classic quick steam boiler with pipe coil and piston pump.

Depending on the water level in the pressure vessel, the feed water in the pressure vessel is replenished by the boiler pump through the economiser.

The burner is controlled depending on the steam pressure. The heat from the flue gas is transferred through the pressure vessel to the water by a multiple path system.

The steam is dried in the internal system of the pressure vessel.

In the economiser, additional heat from the flue gas is transferred to the fresh water in the counter flow.
