“丙烷”应用在铁路信号灯上是一件新技术,已经哈尔滨局试验成功,在新望哈车站两架信号机上安装试用。丙烷是石油裂化出来的一种副产品,近来由于我国石油工业、化学工业有了飞跃的发展,现在有大量丙烷的回收,可以用来代替煤油。以丙烷做燃料的优越性很多:从运用情况看来,丙烷做信号灯燃料完全能满足运输要求,其效果优于煤油信号灯。丙烷灯发光强度约等于煤油灯发光强度的一倍牛,丙烷灯的红光比较少,接 The application of “Propane” on railway signal lights is a new technology that has been successfully tested in Harbin Bureau and installed on the two signal stations of Xincheng Railway Station. Propane is a by-product of petroleum cracking. Recently, due to the rapid development of China’s petroleum industry and chemical industry, there is now a large amount of propane recovery that can be used to replace kerosene. Advantages of using propane as fuel are numerous: from the point of view of operation, propane as a beacon fuel can fully meet the transportation requirements, and its effect is superior to that of kerosene signal light. Propane lamp luminous intensity is about equal to the kerosene lamp luminous intensity of cattle, propane lamp less red, then
