Steam power plant configuration, design, and control Xiao Wu,1 Jiong Shen,1 Yiguo Li1 and Kwang Y. Lee2∗ This article provides an overview of fossil-fuel power plant (FFPP) configura-tion, design and especially, the control technology, both the conventional and the advanced technologies. First, a brief introduction of FFPP fundamentals and con-
Using the wrong materials in a steam plant can increase the potential for corrosion, scaling, and deposition. For example, water and steam chemistry control is much simpler and more efficient when copper alloys are avoided throughout the cycle. Control Of copper-alloy corrosion requires boiler, feedwater, and condensate treat- ment chemicals.

A given mass of steam can hold five to six times more energy than an equivalent mass of water. It can be generated efficiently; many boilers operate with >80% thermal efficiency. It can be distributed easily by creating a pressure difference in the steam system. It is non-toxic and does not damage the environment.

The thermophysical properties of steam change as its conditions of state change and it is relatively easy to generate steam across a wide range of states. Consequently steam has a very wide range of applications. The following brieflydescribes a few of the major thermophysical attractions of steam to the engineer. An explanation of
