  • Secundary air flow measurement for power generation industry

    Secondary Air Flow Overview: The need for accurate, repeatable & reliable combustion air measurements in power generation plants is critical to efficient operation and safety throughout the entire facility and processes. Accurate secondary air flow measurement to the burners is critical for maintaining the proper air to fuel ratio, result­ing in more complete and stable combustion, better performance and lower emissions. Coal-fired power plant applications pose a number of challenges to obtaining these critical flow measurements including large ducts, limited metering runs, poor velocity and temperature profiles, vibration and high temperatures.

  • Primary air control for coal-fired power plants

    Power Generation Combustion Air Measurements: The need for accurate, repeatable & reliable combustion air measurements in power generation plants is critical to efficient operation and safety throughout the entire facility and processes. Coal-fired power plant applications pose a number of challenges to obtaining these critical flow measurements includ¬ing large ducts, limited metering runs, poor velocity and temperature profiles, high vibration, temperatures up to 750° F and dirty `Fly Ash` laden air.

  • Dye Tracing

    Monitoring the dilution and movement of a tracer introduced into the water column provides an excellent means of determining the path that may be followed by a discharge and the rate at which dilution is likely to take place. Fluorescent dyes such as Rhodamine, Fluorescein or Agma are the most frequently used tracers for such investigations. Chelsea Technologies has been providing dye tracing systems for over 30 years. Typical applications include sub-sea pipeline leak detection, pollution studies, natural water flow analysis (rivers, lakes, ocean currents, cave water flows, groundwater filtration etc), sewer and storm water drainage analysis. The Chelsea systems can be configured for a wide variety of tracers, are highly sensitive, robust, and deliver real-time data. They can be moored, profiled, towed or affixed to ROV / AUV platforms.

  • Variable frequency drive controls AC motors

    Consider integrating a variable frequency drive. It often can optimize energy efficiency by enabling you to match motor speed to the demands of the system. Look for opportunities, for example, to replace throttle valves or dampers used to restrict flow. However, a variable frequency drive may not make sense if the load on the motor is relatively small and constant — because speed changes will occur infrequently and any benefits from varying the speed will be negligible. So, thoroughly assess the system load profile to determine the scale and frequency of required speed changes before deciding about installing a variable frequency drive.
