48 This method controls NO formation by limiting the amount of air (or oxygen )in the combustion process to just a bit more than is needed to burn the hydrocarbon fuel in question.
49 For example,the reaction for burning natural gas is:
CH4+2O2=2H2O+CO2
50 Nitrogen in the air used for combustion will compete with the natural gas for oxygen ,in the competitive reaction
N2+O2=2NO
参考答案:48 这一个方法藉由仅仅限制在燃烧程序中的空气 ( 或氧 ) 的数量为没有控制形成有一点超过被需要燃烧问题的碳化氢燃料。
49 举例来说, 反应为燃的天然气是:
CH4+2 O2=2 H2O+ CO2
50 被用为燃烧将会竞争由于天然气作为氧的空气氮 , 在竞争的反应方面
N2+O2=2 NO
