Gasified fuel burner for burning a liquid fuel and water in a gaseous mixture

Claim 2

A gasified fuel burner adapted to convert a liquid fuel and water into a mixture of a gasified fuel and steam for combustion of the fuel in gasified state, comprising a combustion cylinder, a gas chamber defined in said combustion cylinder and formed with an opening substantially in its central portion, a diffuservaporizer rotatably mounted in said combustion cylinder and formed with an opening disposed in spaced juxtaposed relationship to said opening in said gas chamber, with a fuel scattering clearance of a size large enough for the liquid fuel to move therethrough and scatter in the combustion cylinder in atomized particles formed between the opening in the diffuser-vaporizer and the opening in the gas chamber to sustain combustion of the liquid fuel, a frusto-conical blast supply member extending through the gas chamber into the diffuser-vaporizer to supply a stream of air under pressure to the diffuser-vaporizer and then to the gas chamber, a steam generating annular chamber provided at the end of a flame ejecting opening of the combustion cylinder for heating supplied water by the heat produced by combustion of the fuel in liquid state and generating superheated steam therein, a steam line connected at one end to said steam generating annular chamber and opening at the other end in said frusto-conical blast supply member so that the superheated steam produced in said steam generating annular chamber is mixed with the gasified fuel produced in said diffuser-vaporizer together with the stream of air supplied under pressure through the blast supply member, and a combustion plate provided at the periphery of the gas chamber for ejecting therethrough a mixture of gasified fuel and superheated steam together with the stream of air supplied under pressure through the blast supply member whereby combustion of the gasified fuel can be carried out satisfactorily.
