Abstract

Corrosion processes appearing on the watertubes in a combustion chamber of pulverized coal-fired boilers require permanent control and service. Subject to the power plant strategy, different anti-corrosion protection methods can be applied. Technical-economical analysis has been performed to evaluate and support the decisions on maintenance and operation services. The paper presents and discusses results of the application of an air protection system in boiler OP-230 in view of anti-corrosion measures. It is indicated that a low-cost protection method of watertubes (evaporator) against corrosion can be efficient and lead to financial savings in comparison to the standard procedure of replacement of watertube panels.
