In a boiler furnace, incomplete combustion due to insufficient air yields an excess amount of _______________.
AI Explanation
The correct answer is D) carbon monoxide.
In a boiler furnace, incomplete combustion due to insufficient air supply results in an excess production of carbon monoxide (CO). This is because with insufficient air, the fuel cannot undergo complete combustion, leading to the formation of CO instead of the complete combustion product, carbon dioxide (CO2). The other options, sulfur dioxide and nitrogen oxide, are not directly related to incomplete combustion caused by air deficiency in a boiler furnace.
