    Improving Burner Control with Gas Chromatographs

    There once was a time for industrial manufacturers when they received fairly homogeneous supplies of natural gas that did not vary much in energy content. Here in the U.S. with the rapid increase in shale gas production as part of the overall energy mix, there is more variance. In a Power magazine article, Gas Chromatographs Offer New Technology for Power Plant Burner Control , Emerson’s Bonnie Crossland describes...

    Calibrating Toroidal Conductivity Sensors

    By Dave Joseph, Emerson Conductivity measurement is one of the most ubiquitous in industry so the issue of how to correctly calibrate a toroidal conductivity sensor comes up for a lot of plant personnel. Because the purpose of the measurement is to get information about the total concentration of ions in solution (i.e., the conductivity), the effect of sensor dimensions and windings must be accounted for. The correction...

    Optimizing Ammonia Usage in NOx Emission Reduction Processes

    Mono-nitrogen oxides (NO x ) including NO and NO 2 are byproducts of combustion where it occurs in the presence of nitrogen. Since the composition of the atmosphere is 78% nitrogen , this would include most places where this combustion occurs. These NOx gases : …react to form smog and acid rain as well as being central to the formation of tropospheric ozone . To control the level of NOx emissions to meet regulatory...
