Aerospatiale Nord 262: Aircraft Combustion Analyzers

Combustion analyzers are specialized instruments used to measure gases produced during the combustion process, including oxygen (O2), carbon monoxide (CO), and stack temperature. They help optimize combustion efficiency by ensuring the correct fuel-to-air ratio, which is crucial for reducing fuel costs, minimizing harmful emissions, and ensuring safety in heating systems like boilers and furnaces.

A combustion analyzer uses sensors to help determine how efficiently fuel is being burned. Many analyzers include a probe that is inserted into the flue or exhaust system to collect data. The device calculates parameters like combustion efficiency, excess air, and flue temperature to provide a comprehensive analysis of the combustion process.

Combustion efficiency is a measure of how effectively fuel is converted into usable heat during the combustion process. It is calculated based on the levels of O2 and CO in the flue gases, along with flue gas and inlet air temperatures. High combustion efficiency means that the fuel is being burned completely, with minimal heat loss, leading to lower fuel consumption and reduced emissions.

Yes, many combustion analyzers are designed to work with various fuel types, including natural gas, oil, propane, and even wood. These devices often come with preset fuel profiles that allow the user to select the type of fuel being analyzed, ensuring accurate measurements and calculations.

Calibration frequency depends on the manufacturer's recommendations as well as the frequency of use. Test Products International (TPI) recommends that its combustion analyzers be calibrated every 12 months.
