  • Fuel physical property determination method and fuel physical property determination device
    Patent number: 9322818
    Abstract: The fuel physical property determination method relating to the first aspect of the present invention includes: a test fuel flame-imaging step of obtaining imaging data by imaging flames formed by supplying a pre-mixed gas containing a test fuel and an oxidant agent, to a test tube in which an internal flow path thereof has a diameter set smaller than a flame-quenching distance at normal temperature; and a physical property determination step of determining a physical property of the test fuel by comparing the imaging data obtained in the test fuel flame-imaging step and imaging data obtained by imaging flames ignited by supplying a pre-mixed gas containing a standard-mixed fuel and an oxidant agent, to the test tube, the standard-mixed fuel having a known physical property.
