Boiler Tubes Overheating Failures and Actions to Control Them

Boiler tube failures continue to be the leading cause of forced outages in fossil-fired boilers. To get your boiler back on line and reduce or eliminate future forced outages due to tube failure, it is extremely important to determine the specific root cause. One of the main reasons for boiler forced outages is boiler tube leakage. The plan was to carry out for experimental investigation and analysis of the boiler tube failure, and then strategy is to implementation of plan with different power plants and failure techniques until it was considered effective. This paper aims to covers the major reasons of Boiler tube Leakages and effective design considerations and recommended suggestions to avoid the same. Failure analysis methodology is applied to the principal mechanisms by which boiler tubes fail during service. Several important factors often associated with component failures are deficiency in design, fabrication, operating conditions and expended useful life.
