Waste heat boilers — Sandvik Materials Technology

The Sandvik program includes composite tubes for use in waste heat boilers in metallurgical plants. Composite tubes with Sandvik 3R12 (ASTM TP304L) outer layer provide excellent protection against flue gas (for example SO 2) corrosion. Sanicro ® 28 (UNS N08028) is an even better oxide former and used for more severe conditions.

What is a Waste Heat Boiler? (with picture)

2022/1/31 · A waste heat boiler uses the heat formed as a byproduct of another process, heat which would normally be wasted, and uses it to create steam. The steam can be used to drive turbines which produce electricity. Alternatively, the boiler can simply be used to heat water or other kinds of fluid.
