Modern industrial turbines are custom-built to meet specific operating conditions differing so widely from each other that rarely are identical turbines built for different purchasers. This is particularly true in the field embracing turbine generators rated from 5oo to 75oo kw, and including almost every conceivable variation in type and operating conditions. Initial steam pressures, for example, range from atmospheric pressure to more than 2000 lb. per square inch, and this diversity of operating steam pressure, coupled with other variables, results in a different design for almost every application. The proper application therefore is a specialty in which a knowledge of design plays an important part. But many practicing engineers at one time or another are confronted with the problem of turbine application, who do not have this specialized knowledge. Sometimes the result is a ntis-application. The book at hand was written for just such cases.
