Waste Heat Recovery

Waste heat recovery

Features of the high pressure steam boilers:

  • tubesheet cooling to prevent nitriding;

  • channels in contact solely with the cooled synthesis gas leaving the boiler;

  • freely-movable U-tube design of the bundle;

  • internal bore welding, the heat exchanger tubes are joined to the tubesheet by means of full-penetration welds;

  • steam/boiler water separation in the upper part of the waste heat boiler.

The design of high pressure synthesis loop boilers is a long-standing tradition at thyssenkrupp Uhde dating back to 1969 when equipment of this type was pioneered.

Advantages of high pressure steam boilers:

  • all components fabricated from hydrogen-resistant, easy-to-handle, low-alloy materials;

  • elimination of stress corrosion cracking and crevice corrosion;

  • low thermal stress;

  • integrated boiler feed water preheating;

  • tube-to-tubesheet welds all subjected to non-destructive tests.
