Development of enhanced technology and equipment for heat transfer promises significant benefits for many processing operations. Here’s a look at some interesting innovations to improve heat exchanger performance.
Special designs of open-rack heat exchangers use ambient-temperature seawater for heating and cooling. This article looks at the design, operation and maintenance of such exchangers as well as key mechanical considerations.
Keep Out of Hot Water-- Some simple steps can ease heat exchanger commissioning.
Three parameters govern a heat exchanger's effectiveness.
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.
HTRI plans to review and analyze specific exchanger services to develop design margins for use in sizing heat exchangersrather than relying on fouling factors.
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.
Guidelines for designing a shell-and-tube heat exchangers.
More analysis is needed to determine if a new tank and heat exchanger are needed to maintain temperature.
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.
Respondents disagree on whether switching a heat exchanger from spiral to shell and tube is a good idea.
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.
Mistakes in piping around heat exchangers and jackets can cause serious problems in operations and maintenance. Here are several best practices to follow.
Heat Transfer Research is launching an industry-wide effort to examine the way heat exchangers are designed. The goal of the effort is develop engineering design margins for use in sizing heat exchangers for the chemical manufacturing industry.
Alleviate Heat Exchanger Flaws
Process engineering & chemical manufacturing: Heat exchanger design has usually accounted for fouling by adding extra resistances, or fouling factors, to the overall heat transfer coefficient.
Make the Best of a Blunder -- Readers suggest ways to get an incorrect exchanger to do the job.
Water sprays may boost performance of air-fin exchangers.
The Heat Exchange Institute released the first edition of Standards for Gasketed Plate Heat Exchangers.
Video was created to give steam system designers and operators a visual insight to the most effective way to operate steam heat exchange.
Heat Exchange Institute Releases Standards for Air Cooled Condensers -- First edition outlines design criteria and typical purchaser requirements.
