Superheaters & Economisers in Detail
Within a boiler, the superheater is where the steam from the drum is passed through the hot gases exiting from the furnace to raise its temperature further. Superheaters work at the edge of their metallurgical limits because unlike all other tubes within a boiler which are fully flooded with water, the tubes are only wetted with steam, which means they operate at much higher temperatures and even though they are made from higher and more exotic grades or steel, they have a finite lifespan (approx 100,000hours) even in optimum conditions. Consequently they require close inspection and monitoring, and periodic replacement.
