Boiler Tube FailuresBoiler Tube Failures

Boiler Tube Failures

Super heater and reheat super heater tubes commonly fail after many years of service, as a result of creep. During normal operation, alloy super heater tubes will experience increasing temperature and strain over the life of the tube until the creep life is expended. Furnace water wall tubes also can fail from longterm overheat.

Superheater Wikipedia

A superheater is a device used to convert saturated steam or wet steam into superheated steam or dry steam. Superheated steam is used in steam turbines for electricity generation, steam engines, and in processes such as steam reforming.There are three types of superheaters: radiant, convection, and separately fired. A superheater can vary in size from a few tens of feet to several hundred feet
