The pulverized coal-air flow ignitionlimit is mainly influenced by such parameters as initial temperature, ignition source temperature, coal rank and the fineness of the pulverized coal.
煤粉气流的着火界限主要受初始温度、点火源温度、煤种和煤粉细度的影响;

Using a small flow number atomizer may obviously improve the lean ignitionlimit of the high density fuel, but the ignition velocity-pressure limit and the rich ignitionlimit are shrunk.
使用小流量数喷嘴可显著改善大比重油的贫油点火性能,但点火的压力-速度边界和富油点火边界缩小了。

In addition, the influence of the spark energy, the gas stream speed and the electrode distance on the lean ignitionlimit of the gasoline-air mixtures by an automobile ignition coil was determined.
