What is the function of the probe in a combustion analyzer?

The function of the probe in a combustion analyzer is primarily to sample flue gases. Combustion analyzers are tools used to evaluate the efficiency of combustion processes, and the probe plays a crucial role in this by collecting samples from the exhaust gases that come from combustion systems such as boilers, furnaces, and engines.

When the probe is inserted into the flue gas path, it measures the concentration of various gases, including carbon dioxide, carbon monoxide, oxygen, and other pollutants. This information is vital for determining combustion efficiency, diagnosing operational issues, and ensuring compliance with environmental regulations.

While the boiler stack might be involved in the context of where the probe is used, its primary function is to sample the flue gases directly, which are then analyzed to assess performance and safety. This function allows technicians to make necessary adjustments to optimize efficiency and reduce emissions, thus supporting effective maintenance and operational practices in combustion systems.
