Three parameters govern a heat exchanger's effectiveness.

Heat Exchangers: Prevent Tube Pullout

(Article)

Lack of an expansion joint in the shell of a shell-and-tube heat exchanger to take care of thermal expansion can cause the tubes to pull away from the tube sheets. In addition, flow maldistribution can lead to localized tube pullout.

Reviewing the use of fouling factors in heat exchanger design

(Article)

HTRI plans to review and analyze specific exchanger services to develop design margins for use in sizing heat exchangers—rather than relying on fouling factors.

Assess Heat Exchanger Performance

(Article)

Correlating heat exchanger performance to operating cost or energy savings can be tricky but is very important because it can determine whether an exchanger must be shut down for cleaning or can continue to operate until the next scheduled turnaround.

Heat Exchangers: Don’t Generalize Complex Systems

(Article)

Design temperatures for heat exchangers are important. However, plant operations sometimes doesn’t pay any attention to them. So, it’s important to understand what can happen when design temperatures are completely ignored.

Exchanger Choice Spurs Some Heat

(Article)

Respondents disagree on whether switching a heat exchanger from spiral to shell and tube is a good idea.

Troubleshoot Heat Exchanger: Don’t Jump To Solutions

(Article)

Mechanical problems sometimes can afflict heat exchangers. So, it’s good to know some of the symptoms to look for and to understand how you can diagnose such problems without taking the heat exchanger off line.

Keep Cool When Designing Heat Exchanger Piping

(Article)

Mistakes in piping around heat exchangers and jackets can cause serious problems in operations and maintenance. Here are several best practices to follow.
