Corrosion is recognized as a serious problem in power plants that generate
electricity. Many power plants generating a huge amount of electricity are needed to be
taken care of it. Otherwise, these will cause a serious damage to human life. Corrosion
gives rise to wastage of material in huge quantities, failure of tubes, leakage of tubes,
sudden shutdowns as well as a reduction in the lifetime of components. Also, it reduces
the thermal and electrical efficiency of a power plant to a maximum extent leading to
minimum maintenance, outage, and replacement of cost. In understanding this
problem, the present chapter illustrates the corrosions that take place in the power
plants and preventive measures to be taken to avoid huge destruction to the life on the
earth and to the environment. This, in turn, reduces the maintenance cost and damage
to the human life.
