Abstract
For a number of years, especially since the end of World War II,
the engineering literature has contained an increasing number of references
to forced circulation boilers. Most of these articles extol the
virtues of some one kind of boiler or tend to justify the conventional
natural circulation principles. The range of boiler types covered by
the term "forced circulation" is much broader than usually realized,
and since some of these types are basically quite different the existing
confusion on this subject is understandable. We comaonly think of the United States as a leader in technological
progress and development, and in many fields that is true. There
are other fields, however, where from time to time we t^nd to lag.
This has been especially so with regards to the application of forced
circulation in boilers even though some of the working principles were
originally discovered in this country. It is gratifying to note the
rapid and accelerating interest which is now being shown towards making
up the lost time. In this paper an attempt is made to classify and describe the common
types of forced circulation boilers. By comparison with natural
circulation principles, advantages and disadvantages are brought out.
The ccmparison is not intended to minimize the importance of natural
circ\ilation, but rather to show that forced circulation represents a
step forward in steam generation similar to that of the watertube over
the firetube boiler.
