Which of the following states the major difference between oxidation and fire?
A steady flame in a gas burner is the result of ______.
选项
A、a burning velocity equal to the combustion wave
B、fuel being supplied at the same rate as the combustion wave
C、fuel being supplied at a higher rate than that of the burning velocity
D、a low combustion wave
答案
B
解析
煤气灶的稳定火苗的产生是因为燃料流入的速度与燃烧波相同。本题考查对具体细节的理解。文章第四段第一句If the fuel flows at the same speed as the combustion wave,the result is a stationary flame,like the one in your kitchen gas burner.提到如果燃料流入的速度与燃烧波相同时会产生稳定的火苗。
