BORSIG supplies synthesis gas boilers for gas pressures up to 350 bar (35,000 kPa) and steam pressures up to 160 bar (16,000 kPa). They are used in the synthesis gas loop of ammonia plants. The boilers are equipped with U-tubes and can be mounted both in the vertical as well as in the horizontal positions. With both designs, the steam drum can be integrated into the boiler if requested by the customer. At the same time, a feed water pre-heater can be installed in the boiler when required.
