Combustion & Emissions

The key to fuel economy, lower operational costs, improved safety, and reduced emissions in combustion applications is to find the optimal combustion setpoint.

Combustion is a balance between the ratio of the fuel source and the supplied air. Measuring oxygen (O2) by itself can provide a control point for operation. Measuring combustibles (CO+H2) as well can unlock the optimum control point for operation by minimizing the efficiency losses from excess air and excess combustibles.

As combustion processes continue to be used for power generation and process heating, plant operators will increasingly focus on process efficiency and emission monitoring to achieve their sustainability targets. Flue gas measurement provides a mechanism to optimize combustion control and ensure safe operation of fired heaters and boilers alike. Accurate emission monitoring will continue to allow plant operators to demonstrate that their process remains within the permitted emissions limits, minimizing the risks to human health and the wider environment.


  • Application +


    Industrial Boilers

    Boilers are required to provide the power and steam needed for many industrial processes. Efficient burner control ensures reduced fuel costs and lower emissions, and depends upon optimizing the combustion reaction between oxygen (from air) and the fuel used. An ideal ratio between the two ensures safe and efficient operation with minimal emissions.

    Recommended products: WDG-V, WDG-HPII

    Fired heaters

    Fired heaters are direct-fired heat exchangers that use safe, efficient, and controlled combustion to raise the temperature of feed flowing through coils throughout the heater. They rely on efficient combustion to reduce fuel consumption, minimize emissions and ensure process safety. Depending on the use, these are called furnaces, or process heaters, and are critical to hydrocarbon processing.

    Recommended products: WDG-V

    Steam methane reformers

    Steam reforming is widely used in the hydrocarbon processing industries for the production of important gases, particularly hydrogen, methanol, and ammonia. The steam reforming process uses a furnace that heats a large number of tubes containing a catalyst to produce these important gases.

    Recommended products: WDG-V

    Thermal oxidizers

    Thermal oxidizers are specifically designed for air pollution control, receiving many of the waste streams from the production plant.  Variability in the waste compositions requires constant adjustment of the burner air-fuel ratio, and the swift monitoring of oxygen levels ensures proper destruction removal efficiencies of all emissions.

    Recommended products: WDG-V, WDG-V Blowback, WDG-HPII

    Kilns

    Combustion control is important in a kiln, but can prove challenging due to the high temperatures, high variability in fuel sources, and high levels of dust and particulate matter. Efficient control of the combustion processes in cement and lime production can help reduce the fuel costs involved in creating the significant amounts of energy required, and also lower emissions.

    Continuous emissions monitoring (CEM) systems

    CEM systems constantly analyze gases to measure the released pollutants, demonstrating compliance. Equipment must provide stable, and accurate results that are not subject to cross-interference from other pollutants.
