Aiming at tube burst caused by overheat of tube results from wall tube blockage by scale spalling of superheater of 600 MW boiler of unit 2 in Chaozhou Power Plant,metallographic structure of the sample of ferritic steel tube(T23/T91) near the broken seam of boiler tube,composition and structure of the scale are analyzed,from which generation mechanism and spalling mechanism are concluded.The
FANGKUAI Boiler has customized 8 atmospheric pressure electric heating hot water boilers with a output of 0.176MW (CWDR0.176-95/70-II). The boiler can flexibly adjust the number of operating units according to weather changes and user needs, avoiding the waste of electricity and energy.

Symptoms: Aggressive localized boiler tube corrosion and loss of tube wall.Pits can act as stress-concentration sites which can be initiation points for stress-related corrosion mechanisms. Causes: Oxygen pitting occurs with the presence of excessive oxygen in boiler water.It can occur during operation as a result of in-leakage of air at pumps, or failure in operation of preboiler water
Drawing upon a full century of experience and expertise, Boiler Tube Company of America (BTA) manufactures replacement pressure boiler components and related auxiliary industrial boiler parts for all sizes and styles of boilers, regardless of original OEM.
Cost of boiler tube failures 9/4/2013 Steag O&M Company 7 The cost of boiler tube failures is comprised of three main components; the cost of the repair, the cost of start up oil to return unit to service, and the cost of lost production. A rule of thumb for repair costs of 200000 per day out of service+ cost of material
