ABSTRACT:
An apparatus for gasifying and combusting a liquid fuel, comprising: a fuel spraying nozzle; an air blowing cylinder disposed coaxially with and so as to surround the fuel spraying nozzle; a porous burner cone made of an absorptive porous ceramic, consisting of a practically cylindrical section and a conical section merging into the practically cylindrical section and expanding toward the front, and disposed in front of the air blowing cylinder coaxially with the fuel spraying nozzle; a burner cup of the shape of a hollow cone provided with a suitable number of small holes formed in the wall thereof over the entire area except the central portion thereof around the apex and disposed with the majority thereof received in the conical section of the porous burner cone so that the space formed between the porous burner cone and the burner cup has an appropriate cross-sectional area to prevent the stagnation of the air-fuel mixture within the porous burner cone and to make the air-fuel mixture flow through the space at a flow speed higher than the flaming speed; and a flame holding ring disposed in front of the burner cup for forming stable blue flames. The combustion gas is circulated through the porous burner cone to gasify the fuel droplets sprayed by the fuel spraying nozzle.
