  • Evaluate pressure drop in vacuum systems - Plant Services

    Pressure DropOperating Demand Created by Pressure DropLeaksReduce The Pressure LossResultsWhat is pressure drop in a vacuum system? The idea of pressure drop in vacuum systems is similar in concept to pressure drop in plant compressed air systems. Pressure drop is the difference in operating pressure from the supply point to the use point. In compressed air systems, pressure drop is measured in psid, which means pounds per square inch differential. Pressure drop can be used as a measure of pressure drop in vacuum systems as well, but it is much more common to use inches of mercury as unit of measure. Table 1 illustrates some of the common pressure units used in vacuum and how the scales compare with one another. Note that the top of the table represents atmospheric pressure and the bottom of the table represents perfect vacuum. Also, note that there are two scales that use inches of mercury. Finding the pressure drop in a vacuum system is a simple procedure. First, measure the vacuum at the inlet to the vacuum pump using a reasonably accurate vacuum gauge. Then, using th...

    A vacuum gauge is used to measure the pressure in a vacuum—which is typically divided into two subcategories, high (i.e., hard) vacuum and low (i.e,, soft) vacuum. To select the right pressure device for a specific application requires one to know the desired pressure range and the capability of the pumping system to achieve the desired pressure.

  • Condenser Backpressure High? Check Vacuum System Sizing

    Vacuum System StandardsAir-Venting DevicesFactory Tests Versus Hei RequirementsComparing CalculationsHybrid ArrangementsClosing ThoughtsThe Heat Exchange Institute’s (HEI’s) Standards for Steam Surface Condensersprovides clear directions on capacity requirements for venting equipment when operating in either holding or hogging modes. The capacity in the holding mode is more critical, as it has a direct effect on megawatt generation. The HEI recommends that the capacity of venting equipment in the holding mode “be no less than the values shown in [HEI’s] Table 9 at the design suction pressure to ensure adequate removal capacity under commercial operating conditions.” The HEI defines the design suction pressure for electric generation service as “1.0 inch HgA or the condenser design pressure, whichever is lower.” In addition, the HEI states that the saturation temperature of the gas vapor mixture must be considered as the steam temperature corresponding to the design pressure of the venting equipment less the greater of 7.5F or 0.25 (Tsat –Tcw,inlet). Tsat is the saturation temperature of the liquid in the condenser a...
