Heat Transfer

The use of tube inserts in fired heaters

Martin, M., XRG Technologies

In 1896, Whitham1 reported the successful use of twisted tapes (originally called retarders, and now also called turbulators) to increase heat transfer in boiler fire tubes—their effectiveness in increasing heat transfer is well known.

Getting the most out of your process burner tiles

Baukal, C., Johnson, B., John Zink Hamworthy Combustion

It is often incorrectly assumed that the burner tile is simply a piece of refractory or firebrick. Nothing could be further from the truth.

Specifying internals in sour water strippers—Part 1

A sour water stripper (SWS) system is a common process in petroleum refineries and other processes where hydrogen sulfide is present.

Optimizing for viability—VDU revamp in a brownfield project

Revamping an existing column in an operating plant for higher throughput is a challenge, especially when the column is already operating at its rated capacity.

Stop oxidation and scale growth with high-emissivity coating

Poth, J., Integrated Global Services

Oxidation of external tube surfaces is responsible for metal loss at around 0.25 mm/yr, which limits tube life.

Selection and comparison of thermic fluids in a fired heater

Karre, A. V., Worley Group Inc.; Valsaraj, K. T., Cain Department of Chemical Engineering, Louisiana State University

Hot oil, also called thermic fluid, is a heat transfer fluid (HTF) used in oil refineries and chemical plants.

How to support condition monitoring with wireless instrumentation networks

Cureton, A., Emerson

When WirelessHART first hit the market in 2008, most of the native devices using it were process measurement instruments.

What went wrong with my furnace?

Patel, R., Mahra, R. K., Engineers India Ltd.

We should learn from our own mistakes and experiences, but it is wiser to keep track of and learn from all past mistakes and experiences, including those made by others.
