Question 1558 Deck General
70% to passCombustion can occur inside a piping system such as a vapor collection header in a marine emission control system. Which of the following will not aid in this combustion process?
A
oxygen
B
fuel
C
nitrogen
D
ignition
AI Explanation
The correct answer is C) nitrogen. Combustion requires three main elements: fuel, oxygen, and an ignition source. Nitrogen is an inert gas that does not participate in the combustion process. Unlike oxygen, which supports combustion, nitrogen will not aid in the combustion process inside a piping system like a vapor collection header. The other options, A) oxygen, B) fuel, and D) ignition, are all necessary components for combustion to occur, which is why they would aid in the combustion process rather than prevent it.
