Heating boilers - Import export

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.

BORSIG manufactures reformed gas waste heat boilers for more than 50 years. We supply reformed gas waste heat boilers for gas inlet temperatures of up to 1,200°C and steam pressures of up to 160 bar (16,000 kPa) for petrochemical industry (ammonia plants, methanol plants, hydrogen plants, ethylene plants, styrene plants, MTBE plants, oxo-alcohol plants, direct reduction iron plants, coas gasification plants, gas to liquid plants, and others. Every reformed gas waste heat boiler is designed and manufactured exactly in accordance with the customer´s individual requirements. BORSIG offers two different designs: 1. Reformed gas waste heat boilers with BORSIG´s thin stiffened tube sheet design 2. Reformed gas waste heat boilers with thin flexible tube sheet design.

BORSIG has developed its own boiler design. This boiler design is suitable for all gasification processes. The waste heat boiler is designed as a fire-tube boiler. The hot synthesis gas enters the heating surfaces with a temperature of about 1,400 °C and is cooled down in these tubes to approximately 300 °C. The heat from the synthesis gas is used for generating saturated steam.

BORSIG patented steam superheaters are suitable for steam pressures of up to 160 bar (16,000 kPa). The steam superheaters are arranged direct in line after the waste heat boilers which are connected to the secondary reformer or reformer – depending on the process. The steam superheater can be provided as two stage or one stage, horizontally or vertically arranged. The final design arrangement is determined by the process requirements. We have delivered steam superheaters for superheating saturated steam at a pressure stage of 12,500 kPa from 328 °C to 531 °C by cooling down process gas from 723 °C to 355 °C.
