Alberta Boilers Safety Association (ABSA) Practice Test

What device is used for measuring flue gas emissions?

1. A dead weight tester

2. A calorimeter

3. A stock analyzer

4. A continuous metering device

The correct answer is: A stock analyzer

The appropriate device used for measuring flue gas emissions is a continuous metering device. These devices are specifically designed to monitor and quantify the composition of gases produced during combustion in real time. Continuous metering devices provide critical data on various emissions such as carbon dioxide, carbon monoxide, nitrogen oxides, and particulate matter. This information is essential for ensuring compliance with environmental regulations, optimizing combustion processes, and enhancing safety measures in boiler operations. The other options mentioned are not designed for measuring flue gas emissions. A dead weight tester is used to measure pressure and is not relevant to gas emissions. A calorimeter is an instrument used to measure the heat of chemical reactions or physical changes, and while it can provide insights into combustion efficiency, it does not measure gas emissions directly. A stock analyzer, while it may monitor certain parameters in a boiler system, is not specifically focused on the continuous measurement of flue gas emissions. Thus, the continuous metering device stands out as the correct choice for this purpose.
