  • 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 ...

  • 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 ...

  • Boiler Dissolved Oxygen Control

    DISSOLVED OXYGEN CHEMISTRY Dissolved Oxygen (DO) is a measure of the amount of oxygen, usually thought of as a gas, that is dissolved in a liquid such as water. Oxygen is essential to life and is also the most common element found taking part in corrosion reactions. DO can be thought of as the fuel needed for the corrosion process to proceed. It is the corrosion reactions that necessitate ...

  • Hydrocarbon in Water Monitors using Fluorescence

    Hydrocarbon in Water Monitors using Fluorescence are capable of detecting hydrocarbons as low as 5 Parts per Billion and as high as 10,000 Parts per Million depending on the application.  Because only the target hydrocarbons will fluoresce, these monitors have no significant affect due to water turbidity (rust, dirt, gas bubbles, soot, etc.).  Fluorescence monitors provide a measurement ...

  • Common Boiler Feed Water Treatment Issues and How to Avoid Them

    When treating boiler feed water (the combination of boiler makeup and condensate return water), several issues can arise that cause boiler scaling, corrosion, fouling, and system failure. Below, we break down the most common boiler feed water issues and how to avoid them to help ensure system efficiency and operational safety. While treating boiler feed water is extremely ...

  • BTC coatings for trouble-free Boiler Operation

    In April 2014, the CastoLab® Division of Eutectic Canada performed an on-site coating contract for a Steel Mill. The work was performed on a critical section of the Fume Extraction Ducting: a series of water cooled tubes which remove heat from the exhaust fumes exiting the drop box. Conveyed within the ducting is hot ash debris which is corrosive and very abrasive. In this particular job, the ...

  • Fabrication and evaluation of an attapulgite membrane as the filter for recycling blowdown water from industrial boilers

    Continuous blowdown water (CBW) from industrial boilers is of great quantity and energy, and therefore worth recycling. According to the data from a long period of monitoring, carbonate and sulfate were documented as the main contaminants in CBW. Herein, an attapulgite (ATP) membrane was prepared on a macroporous Al2O3 support through solid state sintering. The prepared membrane ...

  • Insitu analysis of ammonia slip and water vapor using a tunable diode laser for SCR/SNCR optimization and boiler tube surveillance in power plants

    ABSTRACT Environmental Regulations driven by the 1990 Clean Air Act require Power Plants to reduce NOx emissions. SCR's and SNCR's reduce NOx emission by injecting ammonia into the combustion flue gas. which ideally reacts with the NOx to form H?0 and Nj. The efficiency of the SCR SNCR is determined by monitoring the outlet for excess NH3. referred to as NH3 slip. The flue gas sample ...
