What does an orsat apparatus measure?

An Orsat apparatus is specifically designed to analyze the composition of flue gases from combustion processes. It measures the concentrations of gases such as oxygen (O2), carbon dioxide (CO2), and carbon monoxide (CO) in the flue gas stream. This analysis is crucial for assessing the efficiency of combustion and the environmental impact of emissions.

By determining the levels of these gases, engineers can evaluate how well the combustion is occurring and whether any adjustments are needed to optimize performance or reduce harmful emissions. Effective control of combustion processes relies heavily on this type of analysis, making the Orsat apparatus an essential tool in many industrial applications.

Other measurement options listed are important in their own rights but are not relevant to the function of the Orsat apparatus. For instance, while temperature measurement is key in assessing combustion performance, it is not conducted using an Orsat apparatus. Similarly, pressure measurements in a boiler system or the volume of fuel burned are part of overall system management, but they fall outside the purview of what the Orsat apparatus specifically measures.
