Operation and Maintenance
of Boilers
The procedure to be followed in the operation and maintenance of a
boiler plant depends to a large extent on its size, type bustion
equipment, operating pressures, steam requirements, and other factors
pertinent to the specific plant. There are, however, standard practices
that any operator should follow to ensure safe, continuous service and
efficient operation. This chapter is intended to assist the operator in
the correct use of the equipment, to recognize unsatisfactory conditions,
and to take the necessary corrective measures before dangerous, costly
emergencies develop.
Fluidized bed boilers have e popular in the burning of waste
fuels and of those fuels which are difficult to burn by bustion
methods. As a result, the operating characteristics of fluidized bed
boilers are discussed in this chapter. Although detail designs do vary
between suppliers, the general features for operation apply to all
designs.
Combined cycle and cogeneration plants have e the primary
power plant additions in recent years. Even though these facilities
burn natural gas, pared with plex solid-fuel-fired
power plants, the heat-recovery steam generators (HRSGs) require
special maintenance attention to ensure high reliability and long life.
These general requirements are discussed in this chapter.
All operators should be trained properly and should follow the operat-
ing procedures of the equipment manufacturers. These procedures are
developed using the experience gained by the manufacturer from many
operating plants, and they should be modified as required based on
the operating experience and specific operating philosophy of the plant.
