White flue gas (resembling steam) coming out of the chimney of a thermal power plant indicates that the fuel used in the boiler furnace is_______?
Correct answer: A. Coke Oven Gas
- A. Coke Oven Gas
- B. Sulphide Coke
- C. Tar
- D. Pulverised coke
Explanation
Coke-oven gas contains hydrogen and hydrocarbons that produce substantial water vapour on combustion, which can appear as a white steam-like plume after cooling. The listed solid fuels do not best explain this characteristic appearance.
