Process flue gas monitoring for combustion optimization - Case Study

• Customer: Any industry having a stake in improved combustion technologies
• Material measured: Combustion flue gases
• Installation: At the boiler outlet
• Function: Reliable and accurate monitoring of O2 and CO for combustion control optimization

Application

Combustion has a number of outputs such as the ash and the emission to the atmosphere of flue gas. Before the flue gas cleaning system, if installed, the flue gases may contain particulate matter, heavy metals, dioxins, furans, sulfur dioxide, and hydrochloric acid. If plants have inadequate flue gas cleaning, these outputs may add a significant pollution component to stack emissions.

Gas monitoring at the boiler outlet

Combustion optimization is not only a question of power. Monitoring the flue gases on a boiler or burner, makes sense ecologically as well as economically. Poor combustion can produce corrosive compounds and ash deposits in the boiler itself. To avoid damage due to these by-products, combustion must be accurately evaluated by monitoring mainly the O2 and the CO.
