Final answer:
The correct type of gas flue analyzer for adjusting a burner and monitoring the results is the Zirconia Analyzer, which offers real-time oxygen measurements to optimize combustion efficiency.
The correct answer is D.
Step-by-step explanation:
The gas flue gas analyzer that allows you to adjust the burner while watching the results on a monitor is the Zirconia Analyzer (D). Zirconia analyzers use a zirconium dioxide sensor to measure the oxygen content of the flue gases and can provide a continuous real-time measurement.
This is particularly useful for burner control, as the oxygen levels in the exhaust can be closely monitored and adjusted to optimize combustion efficiency on the fly, resulting in better fuel economy and reduced emissions.
As the sample burns, the oxygen in the flue gases reacts with the zirconium dioxide, which changes its electrical properties, allowing the monitor to display real-time data. This technology is routinely used in industrial combustion applications, including power plants, refineries, and other facilities with large-scale combustion processes.
