What items can an electronic flue gas analyzer read?

An electronic flue gas analyzer is a device used to measure various parameters of gas emissions from combustion processes, primarily in boiler systems. The ability to measure oxygen (O2), carbon dioxide (CO2), carbon monoxide (CO), temperature, and smoke is crucial for assessing combustion efficiency and emissions.

Oxygen levels indicate how complete the combustion process is. High O2 levels can suggest that too much air is being used, leading to inefficiency, while low levels can indicate incomplete combustion. Carbon dioxide measurements help determine the efficiency of the combustion process; higher levels generally indicate more efficient burning of fuel. Carbon monoxide is a critical indicator of incomplete combustion, which can lead to harmful emissions and safety hazards. Measuring temperature gives insight into the combustion efficiency and helps in analyzing the overall system performance, while smoke measurements provide data on particulate emissions and combustion completeness.

The other choices include parameters that do not necessarily pertain to the standard measurements made by a typical electronic flue gas analyzer. For instance, while temperature is a common measurement, parameters like humidity are not usually monitored in the same context as the combustion gases.
