The statement is accurate because coal, gas, and oil have historically been the three primary fuels utilized for boiler operation. Each of these fuels offers distinct characteristics that make them suitable for particular applications.

Coal has been a traditional boiler fuel due to its availability and cost-effectiveness. It provides high energy content, which is advantageous for generating steam in large industrial boilers. Despite environmental concerns and a shift toward cleaner fuels, coal remains significant in some regions.

Gas, particularly natural gas, has gained popularity because it burns cleaner than coal or oil, producing fewer pollutants. Its ease of use and efficiency also make it a preferred choice for many modern boilers, especially in residential and commercial settings.

Oil, while less commonly used than gas in recent years, continues to be an important fuel source, especially in industries where gas supply is limited. Oil boilers offer flexibility and high energy output.

These three fuels cover a wide range of applications and operational demands, affirming the correctness of the statement regarding their commonality in boiler firing practices.
