  • Application notes: The Sievers InnovOx TOC analyzer: boiler water monitoring

    Background A boiler system is a semi-closed loop system in which water is heated and converted into steam to power a generator. The steam is then allowed to form a condensate and the process is repeated. Boiler water chemistry directly impacts boiler efficiency and fuel use. Improper water treatment allows scale formation and corrosion. Boiler scale and deposits form when impurities ...

  • Scaling vs. Corrosion: Why It Matters for Your Boiler Feedwater System

    When using boilers for an industrial plant and process, one of the most important things to implement is the appropriate treatment of the boiler feedwater before it has a chance to scale and corrode equipment. Before beginning any process with a boiler, understanding the makeup and return water chemistry/characteristics, the manufacturer’s requirements for the boiler (what pressure it ...

  • Power Plant Improves Operating Efficiency with Culligan Matrix Solutions

    Challenge A large chemical manufacture was challenged with boiler tube failures in its power plant, resulting in costly repairs and down time. The boiler tube failures were a result of the incoming water quality to the power plant. Until recently, the boiler make-up water was treated with a combination of carbon media filtration and softening. As a result less than 50% of condensate was ...

  • The advantage of speed for damper drive applications - Case Study

    Overview There certainly is no substitute for speed. In nature, on the athletic field or on the computer, superior speed makes all the difference. Pneumatic-powered damper drives are excellent choices for speed sensitive installations. There are no motor windings or gear sets that can compete on pure speed applications the way a quick acting pnuematic drive can react. For combustion air and ...

  • Luminant Oak Grove Power Station - Case Study

    Powering Texas Luminant, a subsidiary of Energy Future Holdings Corp. (EFH) -which owns competitive and regulated energy subsidiaries in Texas -is the largest electricity generator in Texas. Unit two of the Oak Grove Power plant near Franklin in Robertson County, TX went online in the middle of 2010. Fluor, the project’s EPC company, completed the plant in 35 months and used ...

  • Convection pass lower header closure plate cracking - Case study

    Purpose This bulletin advises owners to inspect for cracks in closure plates and wall tubes located in the convection pass lower header area of UP and RB boilers. Problem Closure plate cracking has occurred between adjacent lower convection pass headers at membrane panel splits. Figure 1 shows the general location of this cracking. In some cases, cracks have ...

  • Reliable silica monitoring supports power station efficiency

    West Burton B CCGT is a Combined Cycle Gas Turbine power station near Nottingham in the UK. It has three open-cycle gas turbines capable of generating enough electricity for approximately 1.5 million UK homes. In common with all combustion based power stations, the CCGT has a requirement to monitor silica levels in the Plant’s water and steam processes. Sean Todd, the Plant’s Control ...

  • Controlling Scale Deposition and Industrial Fouling

    It costs US industry billions of dollars a year to control and remove the limescale that builds up in industrial equipment such a heat exchangers, evaporative coolers, boilers, chillers and other water fed equipment. Oil wells, for example, face significant scaling problems from the highly mineralized water that are extracted with the oil. Limescale not only increases downtime, maintenance ...

  • Recuperative Thermal Oxidizers and midstream natural gas processing - Case study

    A large midstream natural gas processing facility was in urgent need of a VOC abatement device for their newly expanded gas processing plant. The operator was expanding their operations at an unusually fast pace. In the process of bringing on new gas treating capacity, they found themselves up against the limits of their current operating permit. Any new sources would put them over their limits ...

  • Application of Membrane Technology for the Recovery and Reuse of Water

    Abstract As water and sewer costs are expected to increase over the next decade, membrane technology will continue to be a viable and economical option in the recovery and reuse of water. This paper describes the mechanism of membrane effected separation (specifically reverse osmosis, ultrafiltration and microfiltration), membranes commercially available, membrane element configurations, and how ...
