LIQUID FUEL SUPPLYING METHOD

摘要

PROBLEM TO BE SOLVED: To sufficiently restrain generation of harmful matters such as nitrogen oxides or soot at a low cost in combusting liquid fuel in a combustion chamber, by supplying the liquid fuel to the combustion chamber under a condition of a temperature and pressure in which a combustion temperature depressant in the liquid fuel is not in a pseudo critical state or supercritical state. SOLUTION: In this liquid fuel supplying method, a fuel mixture obtained by adding the combustion temperature depressant consisting of liquid having vaporization latent heat higher than 30J/K.mol to the liquid fuel so as to be 1 to 10 wt.% for the total amount of the mixture is supplied to the combustion chamber in a uniform mixing state at 60 to 320 deg.C.
