  • Organics in boiler water condensate

    With the wide use of high efficiency boilers and current high-pressure boilers in industry today limiting condensate analysis to the more traditional parameters can result in very expensive repairs. Condensate return should be the highest quality least expensive water that most systems can generate. Boiler operators do not want to lose this or have it contaminated. Condensate return analysis has ...

  • A connection between cycle chemistry & condenser configuration

    Abstract The most important contributor to power plant chemistry upset conditions and to the overall plant thermal efficiency is the condenser. In-leakage into the subatmospheric pressure, or shell side, of this important balance-of-plant component is responsible for most system wide corrosion, loss of availability and loss of heat transfer in boiler tubes due to deposition of ...

  • Condenser performance optimization and life extension case study

    In 2007 Intek was presented with performance enhancement requirements imposed on an existing Westinghouse condenser. The objective was to determine if the condenser performance could be improved from design capability and to estimate the achievable amount of improvement. The principal drivers for the retrofit were load limiting conditions in the summer time and a desire to switch tube material ...

  • Water and vapor movement with condensation and evaporation in a sandy column

    The diffusion of warm, humid air into an initially cold, dry, sandy column was analyzed to study the movement of water vapor and liquid water under nonisothermal and low water content conditions. The analysis was performed using the HYDRUS-1D code. While the water retention curve of sand was measured experimentally, the unsaturated hydraulic conductivity function was inversely estimated from the ...

  • Noise Measurement

    Definitions Threshold and criterion levels The threshold level is the A-weighted sound level at which a personal noise dosimeter begins to integrate noise into a measured exposure. For example, if the threshold level on a sound level meter is set at 80 decibels (dB), it will capture and integrate into the computation of dose all noise in the employee's hearing zone that equals or exceeds 80 dB. ...


  • A voyage on the seven c`s - phase II common cause correction of a condenser`s conduct & condensate chemistry

    Abstract Experiences in power plant chemistry has moved beyond understanding chemical reactions, controlling reaction rate or preventing reactions from occurring. Today, emphasis is placed on root cause analysis that demands a holistic approach employing multidisciplinary problem solving methods. This may be accomplished through a team effort or the chemist becoming more aware of ...

  • A connection between cycle chemistry and condenser configuration: part II

    Abstract Air in-leakage into the steam space of a condenser can become stored in pockets of high partial pressures that negatively impact condenser performance and become a source of dissolved gases in the feedwater. These pockets can be configuration caused and generally cannot be eliminated by reducing air ingress or increasing venting capacity. Fortunately, engineering designs are ...

  • Total Dissolved Solids (TDS) Measurement

    Definition Total Dissolved Solids (TDS) is a measure of the sum of all inorganic and organic substances in a liquid in molecular, ionized or micro-granular colloidal suspended form. The solids must be small enough to survive filtration through a sieve the size of two micrometer.  TDS solids are normally found in all freshwater systems. Major applications of TDS are: at low levels the ...
