ORNL Uses New Technologies to Take Steam Out of Wasted Energy

07.10.2010
By installing wireless sensors and replacing faulty traps along the 12 miles of steam lines at Oak Ridge National Laboratory, officials expect to save as much as $675,000 per year.

With 1,600 steam traps, which normally open slightly to discharge condensed steam with a negligible loss of live steam, the problem occurs when a trap fails and that failure goes undetected and unrepaired, said Teja Kuruganti, a member of the Computational Sciences and Engineering Division.

Manual inspections of each trap is a daunting and sometimes dangerous task, but by collecting and monitoring data initially from 30 sensors at five steam trap locations, the team of researchers expects to demonstrate significant savings.

Steam is used at ORNL, industrial sites and universities throughout the nation for heating and cooling buildings. A Department of Energy study published in 2005, however, identified faulty steam traps as a major source of energy waste at industrial sites. “Approximately 20 percent of the steam leaving a central boiler plant is lost via leaking traps in typical space heating systems without proactive assessment programs,” the report, “Steam Trap Performance Assessment,” stated.

With this project, ORNL researchers see a chance to save money, reduce the lab’s carbon footprint and lead by example.

Working with Johnson Controls, ORNL has already repaired or replaced any faulty traps, and is considering expanding the wireless sensor system by installing hundreds of sensors.

“The installation of wireless sensors throughout much of the steam system can give us an early warning of component failures or impending failures,” said Wayne Parker of ORNL’s Utilities Division. “Catching problems as early as possible is essential in minimizing losses and maximizing savings.”

Kuruganti noted that wireless capability is “an ORNL hallmark” and this project leverages tools and technologies developed under the DOE Industrial Wireless Program. The sensors will monitor steam flow and temperature. The project will use the ORNL-developed Sensorpedia technology for standards-based information visualization.

Others involved in this project are Glenn Allgood, Joe Lake, Seddik Djouadi, Wayne Manges, Robert Baugh, Teresa Baer, Rob Crowell, Kenneth Woodworth, Mohammed Olama and Rangan Sukumar.

ORNL is managed by UT-Battelle for the Department of Energy's Office of Science.

Im Focus: Can the immune system be boosted against Staphylococcus aureus by delivery of messenger RNA?

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.

Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....

Im Focus: A quantum walk of photons

Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.

Im Focus: Turmoil in sluggish electrons’ existence

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.

We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...

Im Focus: Wafer-thin Magnetic Materials Developed for Future Quantum Technologies

Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.

Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
