Gas Devourer which is fitted to each oil tanker to suck out gasoline vapour remaining in cargo oil tanks after unloading cargo oils, must be so designed as to have short time reguired for sucking and small steam consumption because of steam being wasted away completely. The author has tried the approximate calculation method on characteristic curves of steam ejectors by the same method as tried by Mr. T. Ueda, the Tokyo University, and also some relations between steam consumption and time have been calculated on some typical cases. The following results have been made clear. (1) Steam ejectors which have short guide, long parallel throat and large throat area ratio, have large air ratio at low suction vacuum. (2) It is desirable to use steam of relatively low pressure as driving fluid. (3) Optimum condition has been found to exist in design of gas devourer.
