Heat Transfer

This Series of thermal fluid heaters includes new sizes

With the addition of the ASME Code 16-mil. and 20-mil. Btu/h thermal-fluid heaters, these Btu fuel-fired horizontal heaters are now available from 2.4-mil. to 20-mil. Btu/h output. In addition, the firm offer fuel-fired vertical heaters from 0.2-mil. to 14-mil. Btu/h…

Problem-free pumping of heat-transfer fluids

Etanorm SYT is the latest generation of single-stage volute casing pumps, which were developed for applications in modern heat-transfer systems and hot-water circulation. Besides hot water, the pumps handle mineral-oil-based thermal fluids and synthetic thermal oils at temperatures up to…

Heat Transfer Fluid Leaks: Break the Fire Triangle

Management of process plants requires the understanding and application of the fundamental tenets of safe design, construction, and operation of each facility. In that context, many years of practical experience with systems that use very high-temperature organic heat-transfer media has…

Heat Transfer Fluids: System Filtration

OVERVIEW Indirect heating of processes by organic thermal-liquid fluids offers highly reliable operation, and the heat transfer systems are generally treated as low-maintenance utilities. Occasionally, the heat transfer fluid can become contaminated, resulting in the formation of sludge particles, or…

Controlling Acoustic Coupling

Acoustic coupling in industrial furnaces is an issue that appears to have become more prevalent as designs increase the volumetric heat density of furnaces, and burner technology is required to meet more-stringent emission requirements. The problems associated with acoustic coupling…

Process cooling: Just Cool It!

Like other aspects of chemical processing, cooling operations are being closely examined for ways to reduce costs and resource usage. Whether it’s cooling towers or industrial gases, experts say embracing new technologies makes it possible to get more bang for…
