Which of the following best describes the purpose of combustion efficiency determination?

Determining combustion efficiency primarily involves analyzing flue gas concentrations because this process allows engineers and technicians to assess how effectively fuel is being burned. By evaluating the composition of flue gases, specifically the levels of oxygen, carbon monoxide, and other combustion byproducts, one can gain insights into how complete the combustion process is. This analysis helps in identifying how much of the fuel is converted into usable energy versus how much is wasted through unburned fuel or inefficient combustion, which ultimately informs ways to optimize performance and reduce losses. Understanding these concentrations is crucial for improving overall combustion systems and ensuring they operate within designed parameters.
