In order to accurately produce the kerosene steam used for kerosene sensor calibration and to meetthe needs of the engineering application，we made a reference material selection and solved the technical difficultiesof the occurrence technology of saturated steam compression，precise temperature，and flow control to complete thedesign of kerosene steam generator． This paper presents the modified algorithm of the concentration deviation cor-rection algorithms and temperature compensation tracking method，and completes the testing and error analysis ofkerosene steam generator． The experimental results show that the design meets the requirements of concentrationrange and precision of the steam generator．
