NOx

Emission control: NOx

NH₃ is added in combustion processes to reduce emissions of the flue gas NO_x. The two compounds will react to uncritical N₂ and H₂O. To avoid any corrosive or environmental effects from overuse, the gas volume needs to be continuously monitored.

O₂

Power maximization of hypersonic aircraft engines: O₂

The maximum power, fuel efficiency and stability of hypersonic aircraft engines depend on the captured air volume. Monitoring the oxygen concentration and velocity are important measures to define the airflow.

O₂ & CO

Combustion control in high temperature processes: O₂ and CO

Oxygen control enhances process and cost efficiency of incinerators. Oxidation requires excess air. But too much air cools down the combustion and increases the amount of CO in the flue gas. Real-time and in situ monitoring helps to optimize the oxygen content in combustion processes.

H₂O

Combustion control in high temperature processes: H₂O

Water vapour is often examined in combustion and propulsion processes as it is a primary product of hydrogen and hydrocarbon fuels.

Combustion control in high temperature processes: CO

CO is a major element in high temperature processes. Optimizing CO concentration in flue gas increases combustion efficiency. Simultaneously, it reduces greenhouse gas emissions. CO detection at long wavelengths like 2.8 μm and 4.3 μm uses stronger vibrational absorption features than the shorter wavelength ranges. This effect increases the sensitivity of the detector and allows using measurement set ups with short path lengths.

CH₄

Combustion control in integrated gasification fuel cell cycles: CH₄

Methane content of syngas is controlled to improve combustion efficiency of integrated gasification fuel cell cycles.

CO₂ & CH₄

Combustion control in high temperature processes: CO₂ and CH₄

Continuous monitoring of contents like CO₂ or CH₄ concentrations is essential for the efficiency of high-temperature processes in e. g. incinerators, furnaces or petrochemical refineries. Managing the CO₂ content in combustion processes simultaneously reduces greenhouse gas emissions. This is also relevant for energy generating industries like coal burning power plants.
