Introduction

This chapter gives an overview of microturbine technology. It begins with a discussion of how the technology is unique relative to other distributed generation (DG) as well as to central plants. This is followed by a discussion of special considerations relative to microturbines.

Ultimately, any discussion of microturbine technology, both its positive aspects and its special considerations, provides one with a sense of how best to apply the technology. Later in the book, optimal microturbine applications are described in detail applications that build on the strengths and peculiarities of the technology.

Not all microturbines have the same origins, but there are some similarities. (In a later chapter, the specific beginnings for a particular brand of microturbine will be offered as an example.) Sometimes, specific origins link to the particular strength of a brand. For instance, several manufacturers produce certain components used in microturbines. Many got into the microturbine business by combining their component with other necessary parts to craft an entire microturbine system. The manufacturers then launched a new business line.

Finally, the technology will be described with a focus on its important subsystems and major components. This will be followed by an explanation of how the technology works.

Because this chapter is intended to be a brief overview, it will not teach all there is to know about microturbine technology. Rather, the information provides a basic understanding of microturbines. More detailed information can be obtained through many other technical and trade books and journals, many of which are...
