What instrument is commonly used to monitor combustion efficiency?

The combustion analyzer is the instrument commonly used to monitor combustion efficiency. It provides crucial measurements of gases produced during the combustion process, including oxygen, carbon dioxide, carbon monoxide, and unburned hydrocarbons. By analyzing these gases, the combustion analyzer helps determine how effectively fuel is being burned in a heating system.

Optimal combustion efficiency is essential for maximizing energy usage, reducing emissions, and ensuring safety. The combustion analyzer can also measure temperature and draft pressure, providing a comprehensive overview of the combustion process. This information allows technicians to make necessary adjustments to improve performance and efficiency, ensuring that heating systems operate safely and effectively.

Other instruments listed do have specific functions in measuring temperature and airflow, but they do not specifically address the full spectrum of combustion efficiency. For instance, a thermocouple and a pyrometer are primarily used for measuring temperature, while an anemometer measures the flow of air. These tools do not provide the detailed analysis of combustion gases that is essential for evaluating combustion efficiency, making the combustion analyzer the most appropriate choice for this purpose.
