Outlines the different type of heat transfer equipment such as
Shell-and-Tube heat exchangers, Plate-and-Frame or Compact heat exchangers and Air-cooled heat exchangers. Also
provides criteria for heat exchanger type selection.
|
|
Outlines the construction details of shell-and-tube heat exchangers.
Details such as the shell, tubes, tubesheets, baffles, tie rods and spacers, pass partitions and channels are discussed.
Different types of tube-to-tubesheet joints are explained and typical applications for shell-and-tube heat exchangers are
listed.
|
|
Outlines common operating problems for air cooled heat exchangers
(ACHE) such as: reduced air flow, dirty tube bundles, fan blade pitch, fouling, control and process conditions changes.
It also offers solutions to many of these common problems.
|
|
Discusses overall and film heat transfer coefficients and how
they are calculated. Offers typical values for overall heat transfer coefficients and film heat transfer coefficients.
|
|
Describes fouling
mechanisms encountered in heat transfer equipment such as scaling and crystallization fouling, particulate and sedimentation
fouling, corrosion fouling, chemical fouling, freeze fouling and biological fouling. Pictures of each type of fouling
are provided to help with identification. Design tips to minimize fouling in heat exchangers are also provided.
|
|
Discusses the
use of fouling factors in the design of heat exchangers and the physical and economic considerations which influence the selection
of fouling factors. A link to typical fouling factor values is provided.
|
Start-Up and Shutdown Procedures
|
Discusses the sequence for introducing at start-up
and for removing at shutdown the hot and cold fluids in shell and tube heat exchangers to avoid damage from differential
thermal expansion.
