Steam Boiler: What Is It? How Does It Work? Types Of

Steam boilers used to heat skyscrapers can weigh up to 165 tons and consume 3000 liters of fuel per hour; this is enough to heat 2000 private residences. The use of water and steam for skyscrapers is a very practical and effective method for providing heat since it is easy to transport and readily available.

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.

When used in heating processes, steam loses its latent heat energy and condenses. The resultant condensate is usually over 100°C [212°F], and may contain as much as 30% of the heat energy originally held by steam. When flash steam from condensate is vented to atmosphere, this valuable heat energy, much of which can be recoverable, goes to waste.
