  • Boiling water is easy as one, two, three, four

    There’s more to boiler level control than measuring level and adjusting a feedwater valve. Improved measurements and inverse response are just a few of the influences on operating boilers in a reliable manner.

  • CAGI to verify compressor claims

    The compressed air industry is taking a step that will clear the air about the performance of its equipment. For the first time, many compressed air equipment manufacturers will submit their 50 hp to 200 hp lubricated rotary-screw compressors and 200 cfm to 1,000 cfm refrigerated air dryers to an independent laboratory for performance testing.

  • Implementation fatigue

    The new market realities of higher and rising energy costs as well as global pressures to reduce fossil fuel intensity have made energy management tracking much more valuable. Learn how to keep energy productivity programs from running out of gas in Peter Garforth's latest Energy Expert column.

  • Energy savings are often disguised as problems

    Carefully managing compressed air can save money. Compressed air is often overlooked in energy studies because many people do not fully understand compressed air equipment, their own system, or what it costs to produce compressed air power.

  • Pumping Temperature Considerations

    "Bad actor" pumps are those pumps that have trouble with frequent and repetitive failures. In many cases, the source of the problem is an ANSI pump trying valiantly to handle a liquid well beyond the range of its design rating.of 300 degs. F.

  • Who Will Manage Your Industrial Energy Costs?

    Energy cost control is not a one-time event, and it takes more than one tool to make progress. A number of people, both internal and external to an industrial facility, can contribute to effective energy management.

  • Design methods for reflux condensers

    Reflux condensers have become increasingly important to eliminate condensable organic components from plant off-gas streams and meet environmental requirements. Recognizing this need, HTRI conducted an experimental and analytical study in the late 90s to predict flooding, as well as heat transfer and pressure drop in vertical intube reflux condensers.

  • The Synergy of Simulation, Experimentation and Technical Support Activities in a Research Consortium

    For the business of designing process heat exchangers, computational fluid dynamics (CFD) tools are still not practical for everyday use. However, in a research consortium such as HTRI, integrating advanced analysis tools like CFD with industrial-sized experimentation and then applying them to real-world technical problems provides a significant synergistic benefit to the consortium members.

  • New data support development of spiral plate heat exchanger software

    HTRI has conducted extensive testing on a spiral-spiral single-phase flow unit for a wide range of Reynolds (6.5 to 74,000) and Prandtl (3.8 to 2260) numbers. These data were used to evaluate open literature and HTRI methods.
