    • Chari, S.; Thomas, D. (Energy Systems Laboratory (http://esl.tamu.edu), 1994-04)
      Energy measurements play a very important role in a detailed energy analysis. The role is more important in industrial processes where wide variations of process conditions exist. Valid energy measurements make the decision ...
    • Martin, V.; Falk, M. A. (Energy Systems Laboratory (http://esl.tamu.edu), 2000-04)
      In its most basic step by step form, it sounds quite simple and logical. 1.Find an opportunity to improve efficiency. 2. Carry out the upgrade. 3. Realize the great energy savings that were obtained through the ...
    • Salas, C. E. (Energy Systems Laboratory (http://esl.tamu.edu); Texas A&M University (http://www.tamu.edu), 1981)
      The emerging role of the Energy Manager, from a part time technician to a management level technical administrator can only be accomplished through the understanding of long-range energy control of energy facility energy ...
    • Rogers, E. (Energy Systems Laboratory (http://esl.tamu.edu); Texas A&M University (http://www.tamu.edu), 2015)
    • Baldwin, D. A. (Energy Systems Laboratory (http://esl.tamu.edu), 1985-05)
      Today, substantial savings can be achieved by converting constant flow-rate chilled water systems to variable flow-rate systems. This conversion is best suited for large, central plant chilled water systems where two or ...
    • Corey, R. W. (Energy Systems Laboratory (http://esl.tamu.edu); Texas A&M University (http://www.tamu.edu), 1982)
      Some attempts have been made to normalize the power consumption of mechanical draft cooling towers by ON/OFF and/or multi-speed fan motor operation. These have not proven very successful for the most part for lack of control ...
    • Petro, D. (Energy Systems Laboratory (http://esl.eslwin.tamu.edu), 1993-03)
      Variable frequency drives (VFDs) have found widespread application in recent years. VFDs are valued for their potential to save energy and improve processes. Reliability has improved significantly, but there are still ...
    • Massey, G. W. (Energy Systems Laboratory (http://esl.tamu.edu), 1997-04)
      Variable frequency motor drives (VFD's) have been on the market for many years. Early versions were unreliable and prone to failure. Relatively recent developments in Pulse-Width Modulated (PWM) waveform technology have ...
    • Karassik, I. J.; Petraccaro, L. L.; McGuire, J. T. (Energy Systems Laboratory (http://esl.tamu.edu), 1986-06)
      Variable frequency drive represents a major milestone in the evolution of centrifugal pumps and their application. The fundamentals of variable speed centrifugal pump operation are reviewed, then the advantages and ...
    • Vasel, M. (Energy Systems Laboratory (http://esl.tamu.edu); Texas A&M University (http://www.tamu.edu), 1982)
      The purpose of this paper is to describe an application of variable speed pumping to level control of an industrial process. Topics include a comparison of the process using control valves with a variable speed system, an ...
    • Ganapathy, V.; Rentz, J. (Energy Systems Laboratory (http://esl.eslwin.tamu.edu), 1990-06)
      Heat Recovery Steam Generators (HRSG's) are widely used in chemical plants, refineries, incineration and cogeneration systems and in general for recovering energy from waste gas streams. In applications such as hydrogen ...
    • Butler, K. (Energy Systems Laboratory (http://esl.tamu.edu), 1998-04)
      Motor testing at Advanced Energy has shown that a motor that has not suffered irreparable damage as a result of failure can be repaired to perform as well as before the failure. But the only way to achieve the performance ...
    • Schindler, H. E.; Leaver, E. W.; Shewchuk, C. F. (Energy Systems Laboratory (http://esl.eslwin.tamu.edu), 1988-09)
      The usefulness of models of plant utility systems largely depends on the capabilities of the process system simulator which uses them. SACDA has been engaged in a multi-year development of a versatile and powerful ...
    • Kane, J. F.; Bailey, W. F. (Energy Systems Laboratory (http://esl.tamu.edu), 2000-04)
      Training and development of people is absolutely critical to business success in the 21st century. Achieving this goal is increasingly difficult for many companies, however, due to issues carried over from the 20th century. ...
    • Enneking, J. C. (Energy Systems Laboratory, 1992-04)
      A mobile pilot plant capable of removing VOC emissions from exhaust air streams was cooperatively funded by SCE, EPRI, 3M, and NUCON. Valuable information about the process and the recovery operation has been gained by ...
    • Aue, J.; Fineran, B. (Energy Systems Laboratory (http://esl.tamu.edu); Texas A&M University (http://www.tamu.edu), 2005)
