again be relied upon as the prime electrical power source of the future. Pow-
er production systems must be designed that will produce electrical energy
in the most economical and environmentally responsible way.
Coal-fired System Simulator
A coal-fired electrical power system simulator can’t be used to study this
method of power production. The various subsystems of the coal-fired
power plant are interconnected within the overall system. There are basi-
cally five subsystems for this type of power plant. These subsystems are
the feedwater system, the fuel and air system, the coal-pulverizing system, the
boiler-water system, and the steam and turbine system. Each of these five sub-
systems is shown in the diagrams of Figures 4-7 through 4-11.
Oil-fired System Simulator
An oil-fired electrical power system simulator is very similar to the coal-
fired system. The subsystems are identical to those used in the coal-fired
Figure 4-7. The feedwater subsystem (Courtesy Omnidata, Inc.)
