Industrial Fan Fundamentals
Edward Brunet, Jr., P.E.
Overview
The most suitable fan for a
particular application is dependent upon many factors. Initial cost,
efficiency, operating and maintenance costs, speed, materials, space
constraints, flow rate, pressure, temperature, cleanliness of the product and
the range of operating conditions are all considerations in the selection of a
fan and driver. Improper selection of the fan/driver can result in higher
operating and maintenance costs that far exceed the initial capital cost of the
fan and duct system.
In this course, the student
will learn the fundamentals of axial and centrifugal fans used in industrial
applications and the factors that influence the selection of fans, drivers, flow
control devices and other components of a fan system. The student will
review the document "Improving Fan System Performance: A Sourcebook for
Industry" published by the U.S. Dept. of Energy's Office of Industrial
Technologies.
The student must take a
multiple-choice quiz consisting of twenty-nine questions at the end of
this course to obtain PDH credits.
