Which of the following verification tests is typically conducted alongside combustion analysis?

Combustion analysis is a crucial process that assesses the efficiency of a combustion appliance by measuring the concentrations of various gases produced during the combustion process, such as carbon monoxide (CO), carbon dioxide (CO2), and oxygen (O2). To ensure the combustion process is optimized, it is vital to measure the airflow into the combustion chamber. This measurement helps determine if the appliance is receiving adequate air to promote efficient combustion.

Airflow measurement is often conducted alongside combustion analysis because the ratio of air to fuel directly affects combustion efficiency and emissions. If airflow is insufficient, it can result in incomplete combustion, leading to higher levels of pollutants like CO and lower thermal efficiency. Ensuring that the airflow is measured simultaneously with combustion analysis provides a comprehensive assessment of the appliance's performance and helps identify any potential issues that could affect safety and efficiency.

Other tests, such as voltage analysis, temperature analysis, and pressure drop measurement, may be relevant in certain contexts, but they do not specifically address the relationship between combustion efficiency and the availability of air needed for effective combustion in the same manner that airflow measurement does. Thus, airflow measurement is the most pertinent verification test conducted alongside combustion analysis.
